Yes, blue light from your phone can harm your skin. A dermatologist explains

<p><em><a href="https://theconversation.com/profiles/michael-freeman-223922">Michael Freeman</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>Social media is full of claims that everyday habits can harm your skin. It’s also full of recommendations or advertisements for products that can protect you.</p> <p>Now social media has blue light from our devices in its sights.</p> <p>So can scrolling on our phones really damage your skin? And will applying creams or lotions help?</p> <p>Here’s what the evidence says and what we should really be focusing on.</p> <h2>Remind me, what actually is blue light?</h2> <p>Blue light is part of the visible light spectrum. Sunlight is the strongest source. But our electronic devices – such as our phones, laptops and TVs – also emit it, albeit at levels <a href="https://melasmaclinic.com.au/wp-content/uploads/2024/01/Melasma-LEDS.pdf">100-1,000 times</a> lower.</p> <p>Seeing as we spend so much time using these devices, there has been some concern about the impact of blue light on our health, including <a href="https://theconversation.com/do-blue-light-glasses-really-work-can-they-reduce-eye-strain-or-help-me-sleep-213145">on our eyes and sleep</a>.</p> <p>Now, we’re learning more about the impact of blue light on our skin.</p> <h2>How does blue light affect the skin?</h2> <p>The evidence for blue light’s impact on skin is still emerging. But there are some interesting findings.</p> <p><strong>1. Blue light can increase pigmentation</strong></p> <p><a href="https://academic.oup.com/ced/article-abstract/46/5/934/6598472?redirectedFrom=fulltext&amp;login=false">Studies</a> <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/srt.13401">suggest</a> exposure to blue light can stimulate production of melanin, the natural skin pigment that gives skin its colour.</p> <p>So too much blue light can potentially worsen hyperpigmentation – overproduction of melanin leading to dark spots on the skin – especially in people with darker skin.</p> <p><strong>2. Blue light can give you wrinkles</strong></p> <p>Some research <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6280109/">suggests</a> blue light might damage collagen, a protein essential for skin structure, potentially accelerating the formation of wrinkles.</p> <p>A laboratory <a href="https://pubmed.ncbi.nlm.nih.gov/29399830/">study suggests</a> this can happen if you hold your device one centimetre from your skin for as little as an hour.</p> <p>However, for most people, if you hold your device more than 10cm away from your skin, that would reduce your exposure <a href="https://en.wikipedia.org/wiki/Inverse-square_law">100-fold</a>. So this is much less likely to be significant.</p> <p><strong>3. Blue light can disrupt your sleep, affecting your skin</strong></p> <p>If the skin around your eyes looks dull or puffy, it’s easy to blame this directly on blue light. But as we know blue light affects sleep, what you’re probably seeing are some of the visible signs of sleep deprivation.</p> <p>We know blue light is particularly good at <a href="https://journals.physiology.org/doi/full/10.1152/japplphysiol.01413.2009?rss=1">suppressing</a> production of melatonin. This natural hormone normally signals to our bodies when it’s time for sleep and helps regulate our sleep-wake cycle.</p> <p>By suppressing melatonin, blue light exposure before bed disrupts this natural process, making it harder to fall asleep and potentially reducing the <a href="https://www.tandfonline.com/doi/abs/10.1080/07420528.2023.2173606">quality of your sleep</a>.</p> <p>The stimulating nature of screen content further disrupts sleep. Social media feeds, news articles, video games, or even work emails can keep our brains active and alert, hindering the transition into a sleep state.</p> <p>Long-term sleep problems can also <a href="https://academic.oup.com/ced/article-abstract/40/1/17/6621145?login=false">worsen</a> existing skin conditions, such as acne, eczema and rosacea.</p> <p>Sleep deprivation can elevate cortisol levels, a stress hormone that breaks down collagen, the protein responsible for skin’s firmness. Lack of sleep can also weaken the skin’s natural barrier, making it more susceptible to environmental damage and dryness.</p> <h2>Can skincare protect me?</h2> <p>The beauty industry has capitalised on concerns about blue light and offers a range of protective products such as mists, serums and lip glosses.</p> <p>From a practical perspective, probably only those with the more troublesome hyperpigmentation known as <a href="https://dermnetnz.org/topics/melasma">melasma</a> need to be concerned about blue light from devices.</p> <p>This condition requires the skin to be well protected from all visible light at all times. The only products that are totally effective are those that block all light, namely mineral-based suncreens or some cosmetics. If you can’t see the skin through them they are going to be effective.</p> <p>But there is a lack of rigorous testing for non-opaque products outside laboratories. This makes it difficult to assess if they work and if it’s worth adding them to your skincare routine.</p> <h2>What can I do to minimise blue light then?</h2> <p>Here are some simple steps you can take to minimise your exposure to blue light, especially at night when it can disrupt your sleep:</p> <ul> <li> <p>use the “night mode” setting on your device or use a blue-light filter app to reduce your exposure to blue light in the evening</p> </li> <li> <p>minimise screen time before bed and create a relaxing bedtime routine to avoid the types of sleep disturbances that can affect the health of your skin</p> </li> <li> <p>hold your phone or device away from your skin to minimise exposure to blue light</p> </li> <li> <p>use sunscreen. Mineral and physical sunscreens containing titanium dioxide and iron oxides offer broad protection, including from blue light.</p> </li> </ul> <h2>In a nutshell</h2> <p>Blue light exposure has been linked with some skin concerns, particularly pigmentation for people with darker skin. However, research is ongoing.</p> <p>While skincare to protect against blue light shows promise, more testing is needed to determine if it works.</p> <p>For now, prioritise good sun protection with a broad-spectrum sunscreen, which not only protects against UV, but also light.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/233335/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/michael-freeman-223922">Michael Freeman</a>, Associate Professor of Dermatology, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Your skin is a mirror of your health – here’s what yours might be saying

<p><em><a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/12095893/">Skin accounts for around 15% of our body mass</a>. It is the largest and most visible organ in the human body.</p> <p>Yet many of the skin’s functions are often overlooked. It’s a sunscreen, a shield from germs, a reservoir of <a href="https://pubmed.ncbi.nlm.nih.gov/28994020/">vitamin D</a> and a means of tightly regulating our body temperature.</p> <p>Being the most visible of our organs, the skin also offers us a view into the body tissues that it protects. So don’t think of your skin merely aesthetically – think of it as a reflection of your health. Disorders of the gut, blood, hormones and even the heart might first be seen on the skin in the form of a rash.</p> <p>Here are a few to look out for.</p> <h2>Bullseye</h2> <p>Ticks are pesky creatures that no one will want to return home from a country walk with.</p> <p>But while the vast majority of tick bites <a href="https://pubmed.ncbi.nlm.nih.gov/36116831/">won’t make you ill</a>, there is one rash that should prompt a visit to your doctor if you spot it.</p> <p>Erythema migrans, a rash named for its ability to rapidly expand across the skin, is a hallmark of <a href="https://www.bmj.com/content/369/bmj.m1041.long">Lyme disease</a>, a potentially severe bacterial illness. This rash forms a classic target pattern, like a bullseye on a dartboard.</p> <p>Be vigilant for a few weeks after being bitten to check this rash doesn’t make an appearance – especially if you noticed a red lump that wasn’t there before or if you had to remove a tick from your skin. You should also keep an eye out for other associated symptoms of Lyme disease – such as swinging temperatures, muscle and joint pains and headache.</p> <p>The condition is treated with antibiotics, which can prevent long-term complications, including chronic fatigue symptoms.</p> <h2>Purpura</h2> <p>Some rashes are given a <a href="https://linkinghub.elsevier.com/retrieve/pii/S1538-7836(22)01880-3">colourful namesake</a> – purpura is one such example. This rash’s name is derived from a mollusc which was used to make purple dye.</p> <p>Purpura refers to a rash of small purple or red dots. The cause is pooling of blood into a deeper layer of the skin (dermis). When pressed with a finger – or even better, the side of a glass – it refuses to blanch away.</p> <p>Purpura signals an issue with either the walls of the tiny blood vessels that feed the skin or the blood within them. This might be from a deficiency in platelets, the tiny cell fragments that allow blood to clot – perhaps from bone marrow failure, or an autoimmune condition where the body turns on itself and attacks its own cells.</p> <p>At worst, purpura may signal the life-threatening condition <a href="https://www.magonlinelibrary.com/doi/full/10.12968/hmed.2017.78.8.468">septicaemia</a>, where an infection has spread into the bloodstream – perhaps from the lungs, kidneys or even from the skin itself.</p> <h2>Skin spiders</h2> <p>Skin rashes can also take on <a href="https://pubmed.ncbi.nlm.nih.gov/32513406/">recognisable shapes</a>.</p> <p>Spider naevi represent an issue within skin arterioles (small arteries which supply the skin with blood). Arterioles open and close to control the loss of heat from the body’s surface. But sometimes they can get stuck open – and a spider-like pattern will appear.</p> <p>The open arteriole is the spider’s body, and the even tinier capillaries fanning out in all directions are the thready legs. Crush the body under a fingertip and the whole thing disappears, as your touch temporarily stops the blood flow.</p> <p>Often, these are benign and not associated with any specific condition – especially if you only have one or two. However, more than three suggest higher circulating levels of the <a href="https://dermnetnz.org/topics/spider-telangiectasis">hormone oestrogen</a>, often due to liver disease or from the hormonal changes seen in pregnancy. Treat the underlying cause, and the spiders often vanish with time – though they may persist or reappear later.</p> <h2>Black velvet</h2> <p>Changes to the folds of your skin (usually around the armpits or neck) – especially if it becomes thickened and velveteen to the touch – may suggest a condition known as <a href="https://onlinelibrary.wiley.com/doi/10.1111/jocd.13544">acanthosis nigricans</a>. This “black velvet” skin appearance is more commonly seen in darker skins.</p> <p>Usually, the condition is associated with <a href="https://pubmed.ncbi.nlm.nih.gov/29241752/">disorders of the metabolism</a> – namely type 2 diabetes and polycystic ovary syndrome. If either of these conditions are successfully treated, the rash may fade. In rare cases, it can also be a sign of <a href="https://www.hkmj.org/abstracts/v29n4/355.htm">stomach cancer</a>, which should be considered in patients with few or none of the key signs of metabolic disease (obesity and high blood pressure).</p> <h2>Butterfly rashes</h2> <p>Even disorders of the heart can be visible on the skin.</p> <p>Cardiac valves have the important role of correctly directing the journey of blood through the heart and preventing backflow. The valve between the chambers on the left side of the heart (the mitral valve – so called because of its resemblance to a bishop’s hat, or mitre) can sometimes become narrowed, causing the heart’s function to deteriorate. The body’s natural response is to preserve core blood volume, shutting off flow towards the skin.</p> <p>The net effect can produce a purple-red rash, high across the cheeks and the bridge of the nose, like the outstretched wings of a butterfly. We call this <a href="https://journals.sagepub.com/doi/10.1177/2050313X231200965?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubmed">mitral facies</a> which, depending on the extent of damage to the heart and great vessels, may persist despite treatment.</p> <p>It’s important to pay heed to your skin. It’s constantly talking to you, and any changes in its texture, colour or if new marks or patterns appear, may indicate something is going on beneath the surface.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221937/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, Senior Lecturer, School of Physiology, Pharmacology and Neuroscience, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Sarah Ferguson diagnosed with malignant melanoma – here are the latest treatments for this increasingly common skin cancer

<p><em><a href="https://theconversation.com/profiles/sarah-allinson-137762">Sarah Allinson</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>News that Sarah Ferguson, the Duchess of York, has recently been diagnosed with malignant melanoma highlights the dangers of this increasingly common skin cancer.</p> <p>Malignant melanoma affects <a href="https://www.iarc.who.int/cancer-type/skin-cancer/">325,000 people worldwide</a> every year. While it’s not the most common form of skin cancer – typically, for every one diagnosed case of melanoma, up to ten non-melanoma skin cancers are diagnosed – it causes <a href="https://theconversation.com/skin-cancer-more-people-die-from-types-that-arent-melanoma-surprise-new-finding-215378">almost as many deaths</a>. The reason for this is because it’s far more likely to spread, or metastasise, to other sites in the body compared to non-melanoma skin cancers.</p> <p>Melanoma arises in a type of pigment-producing skin cell called a <a href="https://www.cancer.org/cancer/types/melanoma-skin-cancer/about/what-is-melanoma.html#:%7E:text=Melanoma%20is%20a%20type%20of,to%20grow%20out%20of%20control.">melanocyte</a>. These cells produce and export melanin in order to provide a protective layer in the skin which helps to screen out ultraviolet (UV) radiation.</p> <p>Mutations in genes that normally carefully regulate cell growth and survival override the controls that ensure the body only produces the cells it needs. The result is uncontrolled cellular growth, or a tumour, that normally appears as an unusual-looking mole.</p> <p>The mutations that drive the growth of a melanoma usually happen as a result of exposure to UV from the sun or from an artificial source, such as a tanning bed. We know this because when a melanoma’s genome is compared to that of a normal cell we can see a high number of mutations that have a <a href="https://www.nature.com/articles/s41586-020-1943-3">characteristic “UV signature”</a>. For this reason, melanoma skin cancers occur most frequently in people who have light-coloured skin and who are exposed to high amounts of UV.</p> <p>Non-melanoma skin cancers are also mainly caused by exposure to UV but arise from a different kind of skin cell called a keratinocyte. These are the cells that normally make up the majority of the outer part of our skin, called the epidermis. Cancers that arise from keratinocytes are less likely to spread than those that come from melanocytes – although <a href="https://www.cancerresearchuk.org/health-professional/cancer-statistics/statistics-by-cancer-type/non-melanoma-skin-cancer#heading-One">they can still be fatal</a>.</p> <p>In the duchess’s case, the melanoma was discovered during treatment for breast cancer. Her dermatologist recommended that some moles be removed for biopsy during breast reconstruction surgery. After testing, one was identified as malignant melanoma.</p> <p>If the results of the biopsy show that the cancer hasn’t spread, then like the majority of patients with melanoma, the duchess will be treated with surgery. In this case the tumour will be removed along with some of the surrounding normal skin.</p> <p>The amount of normal skin removed depends on the results of the biopsy – in particular, how deep into the skin the tumour has penetrated (called the <a href="https://www.macmillan.org.uk/cancer-information-and-support/melanoma/staging-of-melanoma">Breslow thickness</a>). The normal skin will be checked for any signs that cancerous cells might have spread out of the tumour.</p> <p>For most people diagnosed with melanoma, particularly if it’s at an early stage, <a href="https://www.ncbi.nlm.nih.gov/books/NBK481850/">surgery will cure the cancer</a> and they will be able to go on with their lives. But for around <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8544364/">20% of patients</a>, additional treatment will be needed. This happens if their cancer has spread further into the body or if their cancer can’t be treated surgically. The <a href="https://ascopubs.org/doi/10.1200/OP.21.00686">good news</a> for these patients is that the past decade has seen huge improvements in treatment.</p> <p>Previously the only options other than surgery were radiotherapy or non-specific chemotherapy treatments. These treatments work by affecting the ability of cells to copy their DNA, which prevents them from duplicating and causes fast-growing cancer cells to die. But because these also affect the patient’s normal cells, they were accompanied by severe side effects – and were often ineffective.</p> <p>But we now have a better understanding of the specific changes melanoma makes to cell growth pathways. This has led to the development of drugs, such as <a href="https://www.cancer.gov/news-events/cancer-currents-blog/2022/fda-dabrafenib-trametinib-braf-solid-tumors">dabrafenib</a> and <a href="https://pubchem.ncbi.nlm.nih.gov/compound/Trametinib">trametinib</a>, that specifically target cells with these altered pathways. In other words, they only target the cancerous cells.</p> <p>These drugs are much more effective and have fewer side effects than traditional chemotherapies – although about half of patients who initially respond to them relapse within a year. In these patients a few of the tumour cells survive by activating other pathways for growth and use these to <a href="https://acsjournals.onlinelibrary.wiley.com/doi/full/10.1002/cncr.30435">regrow the tumour</a>. Promisingly, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10417341/">a recent study</a> suggests that re-using these drugs after a period off them can have good results in relapsed patients.</p> <p>Another exciting development in the treatment of malignant melanoma has been the use of immunotherapies. These involve harnessing the patient’s own immune system to fight the tumour.</p> <p>One particularly successful immunotherapy approach for melanoma involves the use of drugs called checkpoint inhibitors. These prevent cancer cells from being able to hide from the body’s immune system. A <a href="https://www.ejcancer.com/article/S0959-8049(23)00694-9/fulltext">recent report</a> has highlighted how the introduction of these treatments has led to improved survival for melanoma patients.</p> <p>Although the duchess’s skin cancer was discovered while she was being treated for breast cancer, it’s unlikely that the two are related. A more likely risk factor is the duchess’s famous red hair. People with red hair and pale skin that tends to freckle and burn in the sun are at a greater risk of developing skin cancer because their skin produces <a href="https://medlineplus.gov/genetics/gene/mc1r/#conditions">less melanin</a>. This means that their melanocytes are exposed to higher levels of UV and are more likely to undergo cancer-causing mutations.</p> <p>While melanoma is much more common in people with the duchess’s skin type, it’s important to be aware that anyone can get it. It’s a good idea to regularly check your skin for unusual looking moles and to contact a doctor for advice if you have a mole with any of the so-called <a href="https://www.cancerresearchuk.org/about-cancer/melanoma/symptoms">ABCDE characteristics</a>: such as an asymmetrical shape, irregular, blurred or jagged border, uneven colour, is more than 6mm wide and is evolving (either in size, texture or even bleeding).<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221647/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/sarah-allinson-137762">Sarah Allinson</a>, Professor, Department of Biomedical and Life Sciences, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p><em>Image credits: Getty </em><em>Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"I just don't like old skin": Jane Fonda's bizarre confession

<p>Jane Fonda has made an unusual confession about her dating life, explaining why she would only date people of a certain age. </p> <p>The Hollywood legend, 85, has been married three times throughout her life: first to director Roger Vadim from 1965 to 1973, then to activist Tom Hayden from 1973 to 1990, and finally to CNN founder Ted Turner from 1991 to 2001.</p> <p>Fonda is currently single, but doesn't plan on staying that way. </p> <p>Despite being open to finding love, the actress has a very specific criteria for potential suitors to meet before agreeing to a date. </p> <p>On the <em>Absolutely Not</em> podcast, the Oscar winner initially suggested she was done with men for good, saying, “I’m done, I’m over, I’m [almost] 86 years old, even in the dark I wouldn’t want to be naked in front of anybody.” </p> <p>But she then went on to confess that there’s still a chance she could fall for a man, but they would just have to be substantially younger. </p> <p>“And here’s another thing, I’m ashamed to say this, if I were to take a lover, he’d have to be 20. Because I don’t like old skin,” said Fonda.</p> <p>She continued, “And consequently, I don’t want to foist that on anybody else. I assume other people are like me, I just don’t like old skin.”</p> <p>“I disapprove of 86-year-old men with 20-year-old women, so I’m not going to repeat it. I can ogle them, and I can’t pretend that I don’t get turned on if I see a certain kind of a person, but no, no, no, I don’t want to force that on anybody.”</p> <p>Her confession has been criticised on social media, with some suggesting the star would be “cancelled” if it was a man that had said the same about young women. </p> <p>“This is seriously weird,” tweeted one fan, while another said: “But an 85 year old man wanting to date a 20 year old woman is disgusting? Am I right?”</p> <p><em>Image credits: Getty Images </em></p>

Name that rash: 6 common skin conditions (and how to treat them)

<p><strong>Psoriasis</strong></p> <p><span style="text-decoration: underline;"><em>What psoriasis is like:</em></span> Psoriasis is made of red, scaly plaques that can be itchy and painful. It can show up anywhere but is most commonly found on the scalp, as well as the outside of the elbows and knees. It usually starts between age 10 and 30 and tends to be a chronic condition. “It’s a stubborn disease that waxes and wanes, so people have it for their whole lives,” says dermatologist Paul Cohen.</p> <p><span style="text-decoration: underline;"><em>What causes psoriasis:</em></span> This skin rash is the result of your immune system attacking the skin’s cells, and creating new ones too quickly, which then build up into the plaques. There’s no one single cause, but the condition runs in families. Stress, obesity, smoking and having many infections (particularly strep throat) increase your risk.</p> <p><span style="text-decoration: underline;"><em>How to treat psoriasis:</em></span> The first step is generally topical steroids, which can be used for a week or two at a time to clear up the plaques. For ongoing treatment, people use a synthetic form of vitamin D (which slows skin growth), medicated shampoos and retinoids (a topical version of vitamin A). Daily exposure to sunlight also seems to help, as does moisturising well. For more serious cases, options include oral medications that suppress the immune system and phototherapy done in a doctor’s office with a special light. (Discover more applications of light therapy.)</p> <p><span style="text-decoration: underline;"><em>Possible red flag:</em></span> Serious cases can involve the joints, a condition called psoriatic arthritis. Also, psoriasis increases your chances of having some other diseases, including type 2 diabetes, cardiovascular disease and autoimmune conditions such as Crohn’s – all of which are, like psoriasis, linked to inflammation.</p> <p><strong>Hives</strong></p> <p><span style="text-decoration: underline;"><em>What hives are like:</em></span> Hives are itchy, raised welts that often have a red ring around them. Their most salient characteristic is that they disappear after about a day, only to show up later in a different location. They come in two forms: acute, which lasts six weeks or less, and chronic.</p> <p><span style="text-decoration: underline;"><em>What causes hives:</em></span> Hives are often the result of the body releasing histamine as part of an allergic reaction to drugs, food or some other irritant. They also commonly appear after a viral illness, as a side effect of your immune system revving up to battle the disease. “There are a number of potential triggers,” says dermatologist Katie Beleznay. In most cases, she adds, the specific origin is never determined.</p> <p><span style="text-decoration: underline;"><em>How to treat hives:</em></span> Since hives are a histamine reaction, over-the-counter antihistamines are the first line of defence. If that doesn’t clear them up, ask a doctor if you should use a stronger antihistamine or oral prednisone, an anti-inflammatory medication.</p> <p><span style="text-decoration: underline;"><em>Possible red flag:</em></span> Rarely, people suffer from ongoing outbreaks of hives almost daily for six weeks or more, a condition called chronic idiopathic urticaria (CIU). The treatment for CIU is the same as for regular hives, but in some cases, it can also be a sign of an underlying thyroid disease or cancer.</p> <p><strong>Eczema</strong></p> <p><span style="text-decoration: underline;"><em>What eczema is like:</em></span> Eczema presents as patches of red, scaly skin that are extremely itchy, especially at night. These rashes often appear on the inside of your elbows and knees. If it’s more serious, the skin might blister or look thickened and white in those areas.</p> <p><span style="text-decoration: underline;"><em>What causes eczema:</em></span> Eczema is the result of having a weakened skin barrier, which can lead to inflammation and an overreaction from your immune system. Most people are born with it, and your genes are partly to blame. “You’re more predisposed to eczema if you have a family history of asthma, hay fever or the condition itself,” says Lisa Kellett, a dermatologist in Toronto. Some research also suggests that it might be a reaction to pollution, or to not being exposed to enough germs in childhood. (Kids who have dogs, for example, are less likely to have eczema.)</p> <p><span style="text-decoration: underline;"><em>How to treat eczema:</em></span> For general maintenance, apply a thick, hypoallergenic moisturizer to affected areas immediately after a bath or shower and at night. More serious flares will need topical prescription steroid creams or non-steroid immunosuppressant creams. People with stubborn eczema might also try phototherapy, which uses UVB light to help calm your immune system and reduce itchiness.</p> <p><span style="text-decoration: underline;"><em>Possible red flag:</em></span> Rarely, what looks like eczema is actually skin cancer, as both can appear red and scaly. “The difference with skin cancer is that it doesn’t go away if you use a steroid,” says Kellett.</p> <p><strong>Contact Dermatitis</strong></p> <p><span style="text-decoration: underline;"><em>What contact dermatitis is like:</em></span> Contact dermatitis is a variation of eczema, and it looks similar – red, itchy patches on your skin. But unlike that chronic condition, this skin rash is a reaction to something specific and appears only where the offending object has made contact. “Poison ivy, for instance, will show up as a streak where the branch touched the skin,” says Beleznay.</p> <p><span style="text-decoration: underline;"><em>What causes contact dermatitis:</em></span> Besides poison ivy, other common culprits that can cause the immune system to go into overdrive are face cream, jewellery or fragrances. You can also develop a new intolerance to something you’ve used for a long time, such as Polysporin. If it’s not clear what caused it, your dermatologist can do a patch test, putting small amounts of suspected substances on your skin to see if you react.</p> <p><span style="text-decoration: underline;"><em>How to treat contact dermatitis:</em></span> Contact dermatitis is treated with topical steroids, or a stronger oral one, to calm down your immune system and stop the reaction.</p> <p><span style="text-decoration: underline;"><em>Possible red flag:</em></span> Like eczema, the red and scaly presentation of contact dermatitis could be confused for skin cancer, which is another reason to visit your doctor if you’re not sure what caused it.</p> <p><strong>Rosacea</strong></p> <p><span style="text-decoration: underline;"><em>What rosacea is like:</em></span> As rosacea is a dilation of the blood vessels in your cheeks and nose, it often presents as red, sensitive skin in those places. Another form of the condition also includes bumps that resemble acne. For some people, the skin on their nose thickens, making it appear larger.</p> <p><span style="text-decoration: underline;"><em>What causes rosacea:</em></span> We don’t know what brings rosacea on, but, as with eczema, you’re more likely to have it if others in your family do, too. You’re also prone to acquire the condition if you have sun-damaged skin. “Rosacea usually begins around the age of 35 and gets worse with time,” says Kellett. People often find their flare-ups come after eating or drinking specific things.</p> <p><span style="text-decoration: underline;"><em>How to treat rosacea:</em></span> For many, preventing activation of their rosacea is as simple as avoiding triggers – but that’s easier than it sounds and can be a serious test of a sufferer’s willpower. “Those are often the good things in life,” says Beleznay, citing coffee, spicy foods and alcohol as common aggravators. Some women find that everyday makeup is enough to cover up the cosmetic impact of the condition, while others use prescription creams or laser or light therapy to constrict the blood vessels in the cheeks and reduce redness. For those whose rosacea includes bumps, topical creams or oral antibiotics often get rid of them.</p> <p><span style="text-decoration: underline;"><em>Possible red flag:</em></span> Rarely, what looks like rosacea can be confused for the butterfly rash that’s a symptom of lupus, a serious autoimmune disease. The butterfly rash is named as such because of the shape it makes on the nose and both cheeks.</p> <p><strong>Shingles</strong></p> <p><span style="text-decoration: underline;"><em>What shingles is like:</em></span> Shingles normally starts out as a tingly, numb or bruised feeling in a small area, most commonly a patch on the abdomen. A few days later, a painful skin rash with blisters appears over those places. As the condition follows the path of a nerve, the rash eventually presents as a stripe that lasts from two to six weeks.</p> <p><span style="text-decoration: underline;"><em>What causes shingles:</em></span> This one’s easy: chicken pox. Even once you have fully recovered from that virus, your body never totally beats it; it simply retreats and lies dormant in your nerve cells, where, decades later, it can re-erupt as shingles. You’re more likely to get them if you’re immunocompromised or over 50, the age at which most public health agencies recommend you get the vaccine.</p> <p><span style="text-decoration: underline;"><em>How to treat shingles:</em></span> If you suspect you have shingles, see your doctor immediately. “You have to go right away because studies show that people do much better if the antiviral pills are started within 72 hours of the rash onset,” says Cohen. Additionally, sufferers are often given medication, like a local anaesthetic or codeine, to help control the pain.</p> <p><span style="text-decoration: underline;"><em>Possible red flag:</em></span> The real worry with shingles is that for some people, if it is not contained quickly, the virus can lead to longer-term pain lasting over three months and in some cases over a year. If the skin rash appears on the face, it can even cause blindness.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/name-that-rash-6-common-skin-conditions-and-how-to-treat-them" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

The best skin-care routine for oily skin, according to dermatologists

<p><strong>What is oily skin?</strong></p> <p>Oily skin is exactly what it sounds like: skin characterised by the production of a lot of oil. If you’re constantly dealing with shininess, always feel like your face has been hit by an oil slick by the end of the day or tend to notice a bit of oil buildup across your nose and forehead, it may be time to invest in a skin-care routine for oily skin.</p> <p>Need another reason to target oily skin with your daily regimen? Because it produces so much oil (also known as sebum), this skin type often goes hand in hand with acne. But take heart: if you’re battling breakouts, you’re in good company. According to the Australasian College of Dermatologists, acne is the most common of skin diseases and up to 85 per cent of Australians will develop it during their lifetime.</p> <p>Luckily, there are great skin-care formulations that can help oily skin avoid acne and stay healthy, and some formulas may even help curb oil production. Finding the best skin-care routine for oily skin just takes a little know-how, so we reached out to board-certified dermatologists Dr Corey L. Hartman and Dr David Kim to find out what makes a great oily-skin routine.</p> <p><strong>What causes oily skin?</strong></p> <p>“Oily skin is genetic, and it has to do with the size and activity of the oil glands that are associated with the hair follicles,” Dr Hartman explains. “That means if you have thicker hair, you may have thicker or larger oil glands.”</p> <p>Another thing that can impact the amount of oil your skin produces? Hormones. That’s why acne, which is so often associated with oily skin, commonly shows up during puberty, and for those who menstruate, around their periods.</p> <p>Now that you know what triggers oiliness, it’s time to put together your ideal skin-care routine for oily skin – and it’s simpler than it sounds. As Dr Kim notes, when it comes to oily skin types, less is more. “It’s best not to add too many layers for oily skin,” he says. “Otherwise, it can clog your pores and cause acne flares.”</p> <p>If you’re ready to get glowing (but not shiny!) skin, follow the regimen below. Trust us: skin care for oily skin has never been easier.</p> <p><strong>Skin-care routine for oily skin</strong></p> <p>The heart of a good skin-care routine for oily skin has four main daily steps:</p> <p>Cleanser</p> <p>Toner</p> <p>Moisturiser</p> <p>Sunscreen</p> <p>There are additional steps you can add in if necessary or as needed:</p> <p>Exfoliator</p> <p>Acne treatment</p> <p>If hitting all those steps sounds intimidating, don’t worry. We have everything you need to know, including product recommendations.</p> <p><strong>1. Cleanser</strong></p> <p>Every good skin-care routine – including one for oily skin – begins with a good cleanser. You want to use it twice a day: once in the morning to prep your skin to apply your products, and again at night to take off any debris you’ve collected throughout the day.</p> <p>You might’ve heard that you can skip a morning cleansing, but rinsing without washing is better suited to a skin-care routine for dry skin. If yours is oily, go ahead and use a cleanser in the morning and at night.</p> <p>Dr Hartman says that for oily skin, the best face wash is likely “something a little astringent” that uses hydroxy acids or benzoyl peroxide. “You don’t want to do so much that it pushes you in the direction of overly drying,” he explains. That can lead your skin to produce more oil, a process called rebound oiliness.</p> <p>As for the best face wash formulations, Dr Hartman recommends staying away from oils, which can sometimes be comedogenic. (In other words, they can clog your pores.) Instead, look for gel, foam or cream cleansers.</p> <p><strong>2. Toner</strong></p> <p>Toner is technically an optional skin-care step, but many dermatologists recommend it for oily skin because it can help regulate sebum. These watery formulas are meant to eliminate any leftover makeup and grime left after cleansing, while treating the skin with helpful ingredients.</p> <p>What’s the best way to use them? “Once or twice a day on a cotton pad,” says Dr Kim. “Apply to [your] full face.”</p> <p>The best toner for you depends on your goals: Are you aiming for better skin texture? Regulated oil production? A combination of both? According to Dr Kim, if you have oily skin, look for gentle exfoliating acids, such as glycolic or lactic acid, to gently resurface the skin. Or go with salicylic acid to help with sebum control.</p> <p>You’ll know you’ve found the right one when your skin feels soft and smooth after use, not tight or dry. Luckily, unlike the harsh toners of the past, today’s formulas are much gentler and more foolproof.</p> <p><strong>3. Moisturiser</strong></p> <p>Yes, oily skin needs moisturiser. It may sound counterintuitive, but keeping your skin moisturised means it won’t have to work as hard to keep hydration levels up! In fact, Dr Hartman says it’s one of the keys to holding off rebound oiliness. You want to use it morning and night, after cleansing.</p> <p>When looking for the best moisturiser for oily skin, the formula is everything. “I like things that are less creamy and more like a serum or gel base,” says Dr Hartman. “You want something light, nothing too heavy, nothing too emollient,” he explains. In other words, look for terms like daily or sheer, and skip thicker formulas – night creams and bottles marked intense may be too heavy for oily skin. One thing to stay away from: oils, as they can be comedogenic, meaning they may clog pores.</p> <p><strong>4. Sunscreen</strong></p> <p>Sun damage impacts every skin type, including oily skin, so having SPF in your morning routine is non-negotiable. And, yes, that means you need to use it year-round, even on cloudy days and in the winter.   (And don’t forget the scalp sunscreen!)</p> <p>Admittedly, sunscreen can make your skin look a little oily, so finding a nongreasy sunscreen is essential (more on that in a second). But Dr Kim reassures us that’s not impossible. “If you’re using good skin care that helps exfoliate and regulate sebum production, you should be able to wear sunscreen without feeling too greasy,” he says.</p> <p>When it comes to the best face sunscreens for oily types, lightweight daily formulas win. Just be sure yours has an SPF of 30 or higher.</p> <p>Whether you reach for a mineral or chemical sunscreen is a matter of personal preference, and it often comes down to how they wear on your skin (mineral sunscreens can sometimes leave a white cast). “The goal is to find your favourite sunscreen – chemical or mineral – and actually use it every day,” says Dr Kim.</p> <p>Powder sunscreens are a good option for touching up oily skin – they allow you to reapply SPF on the go while soaking up oil. Sunscreen oils, on the other hand, are best avoided. “These can clog the pores,” he says.</p> <p><strong>Exfoliant</strong></p> <p>Exfoliators help remove the dead skin cells that can mix with sebum and clog pores, which is why exfoliating can be an important step in your routine.</p> <p>There are two categories of exfoliants: chemical (like glycolic and salicylic acid or retinols, which increases cell turnover) and physical (scrubs that use friction). Dr Hartman recommends starting with chemical exfoliators, as “they’re a more controlled way of exfoliation,” he says.</p> <p>Apply an exfoliator once or twice a week – or more if your skin can handle it – either in the morning or at night. You may need to start slow, only using it more often if you don’t experience irritation. Beyond that, exfoliate only for very special events, when you really want a glow. That way, you won’t trigger irritation.</p> <p>Dr Hartman’s go-to products for oily skin are prescription retinoids or over-the-counter retinols – not surprising, as these vitamin A derivatives are darlings of the dermatology world. But retinoids are harsh chemicals. “For retinol, start using a pea-size [amount] only twice weekly, and let your skin develop tolerance,” says Dr Kim. You’ll want to apply retinol at night and be extra careful about wearing sunscreen during the day.</p> <p>For people who don’t tolerate them well, Dr Hartman says an alpha hydroxy acid (like glycolic acid) or beta hydroxy acid (like salicylic acid) is a great alternative. If you prefer a physical facial scrub, remember: the finer the particles, the better.</p> <p><strong>Acne treatment</strong></p> <p>First, forget about spot-treating blemishes – if you’re dealing with acne, Dr Kim insists it’s best to treat your whole face. That way, you prevent breakouts before they have a chance to form. And if you’re struggling with breakouts, he says, “you should use at least one prescription cream on your full face to treat existing pimples and prevent new ones.”</p> <p>Heads up: retinoids don’t just aid exfoliation; they can treat acne too. If you’re using a retinoid for acne control and have sensitive skin, you may want to consider this your combo acne and exfoliating treatment. It covers both needs, and including an additional exfoliant in your skin-care routine may cause irritation, especially if your skin is sensitive.</p> <p>If acne is something you grapple with more than occasionally, see your dermatologist for a prescription cream – your doctor will pick the formula that’s best for your skin. If it’s a retinoid, you’ll use this at night.</p> <p>But if you only experience the occasional pimple and would rather go for an over-the-counter option, you’ve got some choices. First things first: you’re going to want a cream rather than a medicated face wash. Sure, face washes offer some acne-fighting ingredients, but you wash them away almost immediately. “Acne wash stays on your face for five seconds, so you need something that will stay on your skin the whole day or night,” Dr Kim explains.</p> <p>While you may see a few other ingredients (like azelaic acid) pop up in the acne world, when it comes to OTC options, there are two all-star ingredients: salicylic acid and benzoyl peroxide. Both are effective, but of the two, benzoyl peroxide tends to get a little more love – it’s especially effective when combined with antibiotics (under a doctor’s care), according to the Mayo Clinic.</p> <p>Just be aware that it can bleach fabrics, so make sure to let it really soak in before getting dressed. And, again, make sure to apply it to your whole face, not just one pimple. Remember, your goal is to avoid pimples in the first place.</p> <p><strong>Skin-care tips experts swear by</strong></p> <p>Armed with our dermatologist-approved skin-care routine for oily skin, you’re well on your way to a less-greasy face. But there are a couple more things to consider as you follow this regimen.</p> <p><strong>Skin care and exercise</strong></p> <p>You know you need to wash your face in the morning and at night. But what if you’re feeling particularly grimy midday? If you work out in the middle of the day, for instance, should you wash your face if you have oily skin? “You probably don’t need to do that,” says Dr Hartman. “Twice a day is enough.”</p> <p>Adding an additional cleansing session may dry your skin out, causing more oiliness. You do want to rinse your face, however. That’ll prevent the sweat, debris and oil from mixing and clogging your pores. And it has the added bonus of leaving you refreshed after a gruelling workout.</p> <p><strong>Smart product use</strong></p> <p>Take your time when introducing ingredients. Before slathering a new product all over your face, do a spot test to make sure your skin can handle it. And when dealing with ingredients like benzoyl peroxide and retinoids, which some people find irritating, start slow to acclimate your face, building to more frequent use as your skin adjusts to the ingredient.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/the-best-skin-care-routine-for-oily-skin-according-to-dermatologists?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Why being married cuts your risk of skin cancer

<p>A new study has found that married couples are less likely to die of skin cancer because they spot warning signs earlier than singles.</p> <p>The study, which observed 50,000 American skin cancer patients, found that 45.7 per cent of those who were married, had stage 1 tumours – which have a 98 per cent survival rate.</p> <p>The chance of catching skin cancer early dropped 32 per cent for singles, 38 per cent for divorcees and 70 per cent for widowers.</p> <p>The researchers from the University of Pennsylvania said they were stunned by the striking difference in diagnoses.</p> <p>The researchers believe these findings should help dermatologists adjust their advice to patients based on their relationship status, suggesting screening at an earlier age for single patients and encouraging home-screen training for those in relationships.</p> <p>Victims of melanoma, the deadliest form of skin cancer, are expected to increase by seven per cent by 2035.</p> <p>For those diagnosed with stage 1 disease, the five-year survival is reportedly 98 per cent. The five-year survival drops to 62 per cent for those diagnosed with stage 3 disease</p> <p>The study, published in the<em> Journal of the American Heart Association</em>, aimed to investigate how lifestyle and relationships could impact patients’ early detection chances.</p> <p>“Spouses likely facilitate early detection of melanomas by assisting in identification of pigmented lesions that may have otherwise gone unnoticed,” said corresponding author Dr Cimarron Sharon, a dermatologist at the Hospital of the University of Pennsylvania.</p> <p>“They may also provide support and encouragement to see a physician for evaluation.</p> <p>“Thus, married patients are likely to receive a better prognosis because of earlier surgical management.”</p> <p>The study also found that married patients were more likely than single, divorced or widowed patients to have a sentinel lymph node biopsy.</p> <p>SLNB is linked to survival as the sentinel lymph node is closest to a tumour and is the first place it would spread.</p> <p>Dr Sharon said this could be “associated with the spouse's role in supporting the patient and engaging in further discussion”. A partner also reduces the difficulty in travelling to and from a hospital and finding a carer post-surgery.</p> <p>This study is the largest of its kind to find the influence of marriage on the detection of melanoma.</p> <p>Dr Sharon said, “These findings support increased consideration of spousal training for partner skin examination and perhaps more frequent screening for unmarried patients.</p> <p>“Marital status should be considered when counselling patients for melanoma procedures and when recommending screening and follow-up to optimize patient care.”</p> <p><em>Image credit: Shutterstock</em></p>

Lumps, bumps and oil slicks: what your skin is really trying to tell you

<p>It is common knowledge to drink water, cleanse, tone and moisture to ensure your skin is healthy, but sometimes these methods aren’t enough. Skincare expert and touch therapist, Sarah Jones, believes that skincare starts from the inside and her approach is based around the idea that your skin reflects the tensions and emotions in your life.</p> <p>“Have you ever noticed that your skin reacts badly when you’re under stress? I can sometimes point to a spot and say, 'This is from that terrible traffic jam I got stuck in yesterday.' Or when you’re giddy with good news, people often comment on your skin, saying you’re “glowing”. Don’t underestimate how emotions play a huge role in how our skin behaves,” Sarah said.</p> <p>Sarah explains the emotions behind common skin complaints.</p> <p><strong>Dry skin</strong></p> <p>Sarah suggests that dry skin can be linked to deep-rooted stress, self-criticism and a little sadness. This is common in those who are caring and help others but tend to forget to look after themselves. Be sure to look after yourself even if it is escaping to have a bath, and if you need to talk to someone, speak to a trusted friend or counsellor.</p> <p><strong>Cold sores and breakouts</strong></p> <p>Both of these skin problems can be an indication of unexpressed anger. Sarah explains that cold sores and spots are nature’s way of communicating that you have gotten off balance.</p> <p><strong>Eczema</strong></p> <p>Eczema, which causes crusting and red patches on the skin, is tedious to treat and can be a real battle to overcome. Sarah believes eczema can be a signal that you feel suffocated in your thoughts and emotionally overwhelmed. She suggests writing down how you feel and finding ways to tackle each emotion.</p> <p><strong>Oily skin and acne</strong></p> <p>Those who have oily skin are prone to large pores and regular but small breakouts. Sarah suggests that this can be a sign that you are not relaxed and you put a lot of pressure on yourself. You may also be prone to highly critiquing yourself. Be sure to focus on your confidence and surround yourself with people who encourage you.</p> <p><em>Images: Getty</em></p>

Hugh Jackman reveals skin cancer results

<p dir="ltr">Hugh Jackman has shared an update on his skin cancer scare just <a href="https://www.oversixty.com.au/health/caring/hugh-jackman-s-health-scare">two days after revealing he had undergone two biopsies</a> to determine whether or not he had basal cell carcinomas. </p> <p dir="ltr">At the time, Hugh explained “basal cell” to be “the least dangerous of them all” when it came to skin cancers, and that he would get his results in a matter of days. It’s also the most commonly occurring, and typically approached with surgery if the biopsy doesn’t remove the cancer first.</p> <p dir="ltr">And now, Hugh has shared his good news, informing his 31.1 million followers on Instagram that his “biopsies came back NEGATIVE!!!” </p> <p dir="ltr">“Thank you ALL for the love,” he continued in his story post, “I feel it! And to the media for helping get this very important message out.”</p> <p dir="ltr">He concluded his statement by reminding everyone to “wear sunscreen with a high level of SPF (no matter the season)”. </p> <p dir="ltr">It was an important message that echoed what he’d told his supporters just two days before, when he explained that “I know you’ve heard me talk about my basal cell carcinomas before. I’m going to keep talking about them, if need be.</p> <p dir="ltr">“And if it reminds even one person to put on sunscreen with a high SPF, then I’m happy.”</p> <p dir="ltr">He went on to add that no matter how much someone might want to tan, it wasn’t worth it, and that his scares were the result of “stuff that happened 25 years ago”.</p> <p dir="ltr">In 2015, Hugh explained to <em>ABC News</em> that his childhood was spent outdoors, and that his “dad or mum ever bought it [sunscreen] or made us put it on”.</p> <p dir="ltr">And in another clip posted to Instagram during one of his previous cancer scares - of which Hugh has had numerous - he urged followers again to take care of their skin health, and prioritise their approach to being in the sun.</p> <p dir="ltr">“If you’re like me and you didn’t really know any better when you were young, and you didn’t wear sunscreen, and you were in the Australian sun, then you need to get a check-up even more.</p> <p dir="ltr">“I just had mine done, I just had a little biopsy. It’s precancerous, it’s not much, but I’m really glad I went.”</p> <p dir="ltr">In total, the <em>Wolverine</em> and upcoming <em>Deadpool 3 </em>star has had six skin cancer removals from his face - all of which took place in 2017 - and another biopsy in 2021. The latter returned an inconclusive result for the actor, when the worst he could have faced was also basal cell carcinomas.</p> <p dir="ltr"><em>Images: Instagram</em></p>

What happens to our skin as we age?

<p>The main factors that contribute to how old we look include the shape of our face, the number of lines or wrinkles, and the luminosity of our skin. Each of these is influenced by intrinsic and external factors.</p> <p>Skin is the most visible organ. So ageing skin has a big impact on a person’s self-esteem. Aussies spend <a href="https://stat.mozo.com.au/images/more-on-mozo/media-releases/twenty-two-billion--the-annual-cost-of-vanity.pdf" target="_blank" rel="noopener">nearly A$5 billion per year</a> on skin care products and treatments, with Queenslanders spending the most on beauty per capita.</p> <h2>Intrinsic ageing of the skin</h2> <p>Rates of intrinsic (also known as chronologic) ageing are predicted, to a degree, by our genetic makeup, including our skin colour.</p> <p>With age, the epidermis (the top layer of the skin) becomes thinner and more transparent. This means that it reflects less light and so appears less luminous as time goes on.</p> <p>The epidermis may also start to develop growths, including small brown dots (dermatosis papulosa nigra and seborrhoic keratoses) and overgrown oil glands, as well as spots that result from ultra-violet (UV) light exposure such as lentigines (freckles), melasma (pigmentation), solar keratoses (sun spots) and skin cancers.</p> <p>Our dermis (the layer of skin under the epidermis) loses collagen and elastin as we age, causing the skin to sag and develop wrinkles when our muscles move under the skin. The blood vessels in the dermis also become thinner, which leads to easy bruising. And because the dermis and epidermis are thinner and hence closer together as we age, the blood vessels become more visible on the surface of the skin with time.</p> <p>The reason collagen decreases as we age is complex, but is partly due to the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1606623/" target="_blank" rel="noopener">reduced function of the cells</a> that make collagen (fibroblasts) and an increase in the enzyme that breaks down collagen.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4174174/" target="_blank" rel="noopener">Research has also shown</a> that fat is lost and bone is resorbed from different compartments of the face at different rates, and this affects our perceived age.</p> <p>When fat disappears from under the eyes (usually in our 20s or 30s), a dark shadow appears, making us look tired. And as the fat pad around the cheeks moves downwards (in our 30s and 40s), lines are created that extend outwards from the nose.</p> <p>Decreases in collagen and elastin cause frown lines and crows feet to develop, alongside other dynamic wrinkles (wrinkles from muscle movement). Meanwhile, the edge of the brow begins to drop and the lips start to thin out.</p> <p>As we move into our 50s, collagen and elastin levels fall further, causing our wrinkles to deepen, and resorption of bone occurs around the eyes causing “bags” to form. Fat hanging from now less-elastic skin causes our eyebrows and nasal tips to droop and the skin on our neck to sag.</p> <p>But intrinsic factors aren’t the whole story. Our lifestyle, environment and habits also play a role in skin ageing.</p> <h2>Extrinsic ageing of the skin</h2> <p>Extrinsic ageing can be induced by environmental factors such as UV exposure, smoking and air pollution. This means the skin’s apparent age and its chronological age are not always the same.</p> <p>UV light breaks down elastin in the dermis, causing saggy, stretchy skin. The skin also bruises and tears more easily and takes longer to heal with ongoing exposure to UV rays.</p> <p>Tobacco smoke results in insufficient oxygen supply to the skin and blocked blood vessels. It reduces immunity (meaning skin cancers can develop more easily) and increases the level of an enzyme that breaks down collagen. Reduced collagen results in wrinkles and loss of volume. Smoking also increases dryness, coarseness and a dull appearance of the skin, and increases wrinkles around the mouth.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pubmed/20664556" target="_blank" rel="noopener">Recent research</a> also suggests a positive correlation between air pollution and extrinsic skin ageing, with 20% more pigment spots noted on the forehead and cheeks of those with exposure to more soot and particles from traffic.</p> <h2>Differences in ageing</h2> <p>So why is it that people of different ethnicities and skin colours seem to age differently? Different types of skin have different amounts of elastin, collagen, pigment cells (melanocytes), and fats.</p> <p>Darker skin has larger, more numerous <a href="https://en.wikipedia.org/wiki/Melanosome" target="_blank" rel="noopener">melanosomes</a>, which manufacture, store and transport melanin, in turn giving the skin pigment. This provides protection against UV rays in people with darker skin types.</p> <p>The average protective factor against UV-B radiation in black skin was found to be 13.4 – compared with 3.4 for white skin, while the average rate of UV-B transmission into the dermis was 5.7% in black skin, compared with 29.4% in white skin.</p> <p>While increased melanin serves as an inbuilt sunscreen, it’s also the responses of these pigment cells that make patients with skin of colour more susceptible to pigment problems over time.</p> <p>And those with darker skin types are said to have a thickened outer layer of the skin with larger and more numerous fibroblasts (cells that make connective tissue and collagen) and compact collagen. This means this type of skin won’t wrinkle as easily, but has a greater chance of keloid scarring (overgrowth of scar tissue).</p> <p>So it seems that not all skin is created equal, but there are things we can do to optimise our skin health. Sun protection (hat, sunscreen, seeking shade) and avoiding smoking are good places to start. Retinoids have been proven to help minimise fine lines, pigmentation and to increase collagen and repair sun-damaged skin.</p> <p>As for the myriad lotions and potions that claim to magically make us look 21 again … if I find one that works I’ll let you know.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://cosmosmagazine.com/health/body-and-mind/wrinkles-liver-spots-crows-feet-what-happens-to-our-skin-as-we-age/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by The Conversation. </em></p>

“Less is more”: Skin doctor shares her holy grail skincare routine

<p dir="ltr">A skin and cosmetic doctor has shared her holy grail skincare routine that focuses on a “less is more” approach for more mature skin. </p> <p dir="ltr">Dr Imaan Joshi, 49, only began her foray into the complicated world of skincare when she was 42, and now had refined her routine to work in her favour. </p> <p dir="ltr">Dr Joshi only cleanses once each day, uses a handful of serums in the morning and puts on hyaluronic acid and retinol before bed.</p> <p dir="ltr">Chatting with <a href="https://www.dailymail.co.uk/femail/beauty/article-11300931/Skin-doctor-shares-products-uses-face-everyday.html">Femail</a>, she admitted she prefers the “wash and wear” approach to achieving healthy skin. </p> <p dir="ltr">“You don’t need 10 steps or whatever to get the job done if you use targeted personalised stuff for you and stop following fads and trends,” she said.</p> <p dir="ltr">“Most of my patients are busy with hectic lifestyles. Keeping it simple means they’re more likely to stick to their routines rather than skip it completely because it’s too hard.”</p> <p dir="ltr">She also says looking after your skin isn't about “looking younger”, but rather about looking healthier.</p> <p dir="ltr">“I think my skin looks better but the goal is never to look younger. I’m not trying to pass as younger, that’s an unintended consequence if it happens, not the goal,” she said.</p> <p dir="ltr">As well as her five minute a day routine in the mornings and evenings, Dr Joshi also likes to do  monthly laser and chemical peels, and an 'anti-wrinkle' treatment every three or four months. </p> <p dir="ltr">She also likes to do micro needling or have a deep hydration done twice each year.</p> <p dir="ltr">While she admits these treatments, creams and clinic visits can “all add up”, she says it's important to invest in your skincare the same way you would your physical health. </p> <p dir="ltr"><em>Image credits: Instagram</em></p>

Top tips for growing tomatoes

<p>Nothing beats the flavour of home-grown tomatoes, so start your own crop today with our top tips for growing tasty tomatoes.</p> <p><strong>Don’t crowd seedlings –</strong> Crowded conditions inhabit growth so be sure to give your seedlings plenty of room. For each plant, prepare at least a 60 centimetre by 60 centimetre plot.</p> <p><strong>Prime location –</strong> Tomatoes need at least eight hours of direct sunlight daily and shelter from strong wind.</p> <p><strong>Plant a few varieties –</strong> There’s so many different types of tomatoes available so grow a few varieties. You’ll soon find that some types just suit your garden better, while others may be susceptible to disease.</p> <p><strong>Staking –</strong> This is essential for tall-growing varieties of tomatoes. Add the stake at planting time and as the plant grows, tie it to the stake. Use soft ties, such as old stockings rather than string. This trains your plant, keeps it stable, takes up less space, prevent damage from strong winds and escapes the adverse effects of damp soil.</p> <p><strong>Water well –</strong> Tomatoes need regular deep watering, especially during the warmer months. Even letting plants go thirsty for a few days will affect the quality of fruit. Water the soil, not the plant.</p> <p><strong>Inspect often –</strong> Check daily for signs of pest or diseases. Remove dead leaves, unwanted shoots and harvest anything that is ready.</p> <p><strong>Companion plant –</strong> Plant marigolds around tomatoes to reduce whitefly infestations. Or sacrifice some basil which will attract white flies away from your tomato. Garlic, nasturtiums or tagetes will repel aphids.</p> <p><strong>Pot plants –</strong> Tomatoes grown in pots are more likely to dry out than those in the ground. However, if that’s not possible, the small bush type do best in pots. Use a big pot and water well.</p> <p><strong>Yellowing leaves –</strong> Once tomato plants reach around a metre tall, the leaves at the bottom might turn yellow and die. This is normal so just snip them off.</p> <p><strong>When to give up –</strong> If there are many yellowing leaves and the plant on a whole looks unhealthy, it may have contracted a bacterial, fungal or virus disease. The plant generally won’t flourish now and it’s best to be pulled out and disposed of. Don’t attempt to grow tomatoes in the same spot for at least a couple of years.</p> <p><em>Image: Getty</em></p>

Why is newborn baby skin-to-skin contact with dads and non-birthing parents important? Here’s what the science says

<p>Soon after a baby is born, it’s getting more common these days for the father or non-birthing parent to be encouraged to put the newborn directly on their chest. This skin-to-skin contact is often termed “kangaroo care”, as it mimics the way kangaroos provide warmth and security to babies.</p> <p>Mothers have been encouraged to give kangaroo care for decades now and many do so instinctively after giving birth; it has been <a href="https://pubmed.ncbi.nlm.nih.gov/27552521/" target="_blank" rel="noopener">shown</a> to help mum and baby <a href="https://www.sciencedirect.com/science/article/pii/S0882596316000531?casa_token=QBk4MOx7VIMAAAAA:3DIH_RF_PdsZDqHkKSYgbM37Tgsau5GpTBPqUowy4kDN3tOwtnnPvpXCGkpBI8lJEQIqSorp" target="_blank" rel="noopener">connect</a> and with <a href="https://connect.springerpub.com/content/sgrnn/27/3/151.abstract" target="_blank" rel="noopener">breastfeeding</a>.</p> <p>So what does the evidence say about kangaroo care for other parents?</p> <p><strong>A growing body of research</strong></p> <p>A growing body of <a href="https://www.researchgate.net/publication/361591701_Fathers_providing_kangaroo_care_in_neonatal_intensive_care_units_a_scoping_review" target="_blank" rel="noopener">research</a> shows kangaroo care brings benefits for both baby and parent.</p> <p>One <a href="https://onlinelibrary.wiley.com/doi/10.1111/apa.14184" target="_blank" rel="noopener">study</a> that measured cortisol (a stress hormone) levels and blood pressure in new fathers found:</p> <blockquote> <p>Fathers who held their baby in skin-to-skin contact for the first time showed a significant reduction in physiological stress responses.</p> </blockquote> <p>Another <a href="https://www.hindawi.com/journals/nrp/2017/8612024/" target="_blank" rel="noopener">study</a> in Taiwan involving fathers and neonates (newborn babies) found benefits to bonding and attachment:</p> <blockquote> <p>These study results confirm the positive effects of skin-to-skin contact interventions on the infant care behaviour of fathers in terms of exploring, talking, touching, and caring and on the enhancing of the father-neonate attachment.</p> </blockquote> <p>A <a href="https://www.researchgate.net/publication/361591701_Fathers_providing_kangaroo_care_in_neonatal_intensive_care_units_a_scoping_review" target="_blank" rel="noopener">paper</a> I co-authored with the University of South Australia’s Qiuxia Dong found:</p> <blockquote> <p>Studies reported several positive kangaroo care benefits for fathers such as reduced stress, promotion of paternal role and enhanced father–infant bond.</p> </blockquote> <p>Qiuxia Dong also led a <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/jocn.16405" target="_blank" rel="noopener">study</a> (on which I was a co-author) exploring the experiences of fathers who had a baby in the Neonatal Intensive Care Unit at Women’s and Children’s Hospital in Adelaide.</p> <p>This study found kangaroo care helps fathers connect and bond with their baby in an intensive care environment. This had a positive impact on fathers’ confidence and self-esteem. As one father told us:</p> <blockquote> <p>I think after all the stress, when I have skin-to-skin I can actually calm down a little bit. I sit down and relax, I can cuddle my child and it’s just a little bit of a happy place for me as well as him to calm down, not to do any work all the time, not to be stressed out. There’s other things on my mind all the time but it’s time to relax and turn off a little bit.</p> </blockquote> <p>Another told us:</p> <blockquote> <p>She nuzzled around a bit, kind of got my smell I guess and then literally fell asleep. It was great. It was very comforting for both I guess for her and myself.</p> </blockquote> <p>As one father put it:</p> <blockquote> <p>Of course, they can hear your heartbeat and all that kind of stuff, of course warmth […] it’s being close with your baby, I think that would be the best way of building a relationship early.</p> </blockquote> <p>However, this study also reported that some dads found giving kangaroo care challenging as it can be time-consuming. It is not always easy to juggle with commitments such as caring for other children and work.</p> <p><strong>Involving both parents</strong></p> <p>One study noted <a href="https://pubmed.ncbi.nlm.nih.gov/21820778/" target="_blank" rel="noopener">dads</a> can sometimes feel like a bystander on the periphery when a newborn arrives.</p> <p>Encouraging and educating all non-birthing parents, including fathers, to give kangaroo care is a <a href="https://pubmed.ncbi.nlm.nih.gov/21820778/" target="_blank" rel="noopener">valuable way</a> to get them involved. And if a caesarean birth makes it difficult for the mother to give kangaroo care while still in theatre, the father or non-birthing parent is the next best person to do it while the mother or birthing parent is not able.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/480777/original/file-20220824-22-j9lpxl.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/480777/original/file-20220824-22-j9lpxl.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/480777/original/file-20220824-22-j9lpxl.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=401&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/480777/original/file-20220824-22-j9lpxl.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=401&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/480777/original/file-20220824-22-j9lpxl.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=401&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/480777/original/file-20220824-22-j9lpxl.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=504&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/480777/original/file-20220824-22-j9lpxl.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=504&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/480777/original/file-20220824-22-j9lpxl.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=504&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><em><span class="caption">A caesarean birth sometimes makes it difficult for the mother to give kangaroo care while still in the theatre.</span> <span class="attribution"><span class="source">Isaac Hermar/Pexels</span>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/" target="_blank" rel="noopener">CC BY</a></span></em></figcaption></figure> <p><strong>More research needed</strong></p> <p>There is a need for broader research on these issues, especially around the experiences of fathers from culturally diverse backgrounds and other non-birthing parents.</p> <p>But the research literature on kangaroo care shows there is good reason for dads and non-birthing parents to do some kangaroo care when a baby is born.

<h2>Kidney disease</h2> <p>Intense itchy skin all over the body often occurs in people with late-stage kidney disease or those who suffer from chronic renal failure. In fact, 42 per cent of dialysis patients suffered from moderate to extreme itchiness, according to a study published in Renal Failure. “Some people describe it as a nuisance,” says dermatologist, Dr Anthony M. Rossi. “[The itch] is so intense that people wake up in the middle of the night scratching.” Science has yet to uncover why kidney disease causes itchiness, but doctors suspect it has to do with the build-up of toxins in your body when your kidneys are unable to remove the waste from your bloodstream.</p> <h2>Liver disease</h2> <p>Itchy skin all over could also be a silent sign of liver disease. Where incessant itchiness shows up late-stage in kidney disease, it can be an early symptom of liver disease. “If your liver is not functioning properly to detoxify the body, byproducts like bile acids back up,” says Dr Kathleen Cook Suozzi, assistant professor in the department of dermatology at Yale School of Medicine. “The primary goal is to treat the underlying liver disease and prescribe medications that can eliminate bile acids.” Doctors will typically prescribe medications that can inhibit your body’s uptake of bile acids or help reduce the amount of bile acid returning to the liver.</p> <h2>Dermatographia</h2> <p>If after lightly scratching your skin, your fingernails leave thin, raised red welts on your skin that take 15 to 30 minutes to disappear, you may suspect dermatographia or dermatographism, a form of chronic hives. “It’s an extreme skin condition, where your skin is sensitive to touch and releases too much histamine,” says dermatologist and cosmetic surgeon, Dr Cameron Rokhsar. Although the cause of this condition is unclear, it may be triggered by stress, infections, allergens, or medications, he says, adding that areas commonly touched by other skin or clothing are the most susceptible to dermatographic flare-ups. It’s easy to diagnose but often goes undiagnosed because it’s not severe or bothersome enough for people to make an appointment with their dermatologist. If the itch becomes severe, your doctor can prescribe an antihistamine to relieve the inflammation, he says. For patients with severe hives who don’t get better with antihistamines, omalizumab injections in a doctor’s office may provide relief.</p> <h2>Spinal disease</h2> <p>Chronic itchy skin on the upper middle section of the back (without a rash) can be a hallmark of neuropathic itch, a symptom of nerve malfunction. Before providing treatment, doctors will first rule out spinal cord disease as a cause. Research has shown that spinal disease, whether due to age or injury, can apply pressure on the nerve and pinch it, which results in an itchy sensation on the skin. Neuropathic itches can occur on one side of the body or both, but it’s a big red flag if scratching brings no relief. “People with eczema get a good sensation from scratching,” says Dr Rossi. “But [nerve itch] doesn’t improve with scratching. The itch intensifies most of the time.” Some people say it feels like insects are crawling on them. Once spinal cord disease or other health conditions have been ruled out, neuropathic itches can be treated with capsaicin cream, which is derived from capsicums, to burn out the nerves that are firing irregularly on the skin.</p> <h2>Coeliac disease</h2> <p>Extremely itchy bumps or blisters on knees, elbows, buttocks, and/or hairline may be signs of dermatitis herpetiformis (DH), a skin manifestation of coeliac disease, says dermatologist, Dr John Zone. Basically, when a person with coeliac disease eats food containing gluten, their immune system responds by producing antibodies called immunoglobulin A (IgA). These IgA antibodies travel to and bind with the skin cells to trigger an itchy response. The prescription Dapsone can provide short-term itch relief for the skin, but if the intestinal damage is serious patients have to adopt a strict gluten-free diet for life. If they continue to eat gluten, coeliac patients can develop malnutrition, anaemia, bone loss, ulcerative colitis, and even cancer.</p> <h2>Lymphoma</h2> <p>“The other thing that you want to rule out are blood disorders,” says Dr Suozzi. “Anywhere from five to 30 per cent of lymphomas such as Hodgkin’s and non-Hodgkin’s can present with itch.” Itchiness with or without a rash can be the first symptom of Hodgkin’s disease – likely caused by cytokines, cell signal molecules that trigger inflammation in response to infection. If your doctor suspects lymphoma, she may order a chest X-ray. If you’re diagnosed with the disease, the itching will cease soon after starting chemotherapy or radiation therapy.</p> <h2>Thyroid disease</h2> <p>“Thyroid disease, whether it’s overactive or underactive, can cause weird sensations in the skin,” says Dr Rohskar. “No one knows the association but it may be that the changes in the sweat glands can cause skin dryness.” Itchy, dry skin is more common in people who have hypothyroid because skin tissue contains thyroid hormone receptors that are seeing diminished cellular activity in the absence of thyroid hormone.</p> <h2>Allergies</h2> <p>Allergies are one of the most common chronic health conditions in the world. In fact, many skin allergies are classified under the umbrella term contact dermatitis, the itchy rash on your skin that you get when you come into contact with an allergen. Plants, nickel, or compounds found in personal care items like baby wipes and makeup are just a few of the allergens that can cause contact dermatitis. If the itchiness is localised to your eyes, if could be a sign of eyelid dermatitis. Your dermatologist or allergist can use a patch test to figure out what your triggers are. “It’s like a treasure hunt when we’re trying to look into all the products that people use,” says Dr Suozzi. A strong topical steroid is prescribed for relief.</p> <h2>Menopause</h2> <p>If you’ve finally hit menopause, you may have noticed a sudden change in your appearance – including dry, itchy skin. The loss of oestrogen, an essential building block for collagen production, leads to thinner, itchier skin due to a diminished supply of natural oils that keep your skin’s moisture intact, says OB/GYN, Dr Sherry Ross. Maintain your fountain of youth with aloe vera gel or calamine lotion, which help hold water in your skin’s outermost layer to alleviate drying and itching.</p> <h2>Breast cancer</h2> <p>Paget’s disease of the nipple is an incredibly rare form of breast cancer where cancer cells collect in or around the nipple. According to Rare Cancers Australia, Paget’s disease of the nipple is more common in women and is often found in people over 50 years old. The first sign is scaly, red, itchy patches around the nipple and areola. “Sometimes it’s misdiagnosed as eczema of the nipple,” says Dr Suozzi. “But when it’s breast cancer-associated, it’s unilateral.”</p> <h2>Pregnancy</h2> <p>The Royal Australia College of General Practitioners states that 1 in 200 women will develop pruritic urticarial papules and plaques (PUPP), an outbreak of itchy red rashes commonly seen on the abdomen, though they can also appear on your legs and arms. Most women can’t do much about the itch because the rash typically doesn’t develop until late into the third trimester when most medications are off-limits. “It’s not proven but some people say [PUPP] can happen with multiple gestations like twins,” says Dr Rossi. “And some people think it’s because the skin gets stretched out.” Fortunately, it’s harmless and goes away after pregnancy.</p> <p><strong>This article originally appeared in <a href="https://www.readersdigest.com.au/healthsmart/beauty/skin/11-things-your-itchy-skin-can-reveal-about-your-health?pages=1" target="_blank" rel="noopener">Reader's Digest</a>.</strong></p> <p><em>Image: Shutterstock</em></p>

12 silent signs of skin cancer you’re probably ignoring

<p><strong>Subtle signs of skin cancer you shouldn’t ignore</strong></p> <p>When the weather gets warmer and daylight hours longer, people are more likely to spend time outdoors in the sun. This also means there’s an increased risk for skin cancer. Australia has one of the highest rates of skin cancer in the world, according to cancer.org.au, which account for around 80% of all newly diagnosed cancers. Although common, it’s also the most preventable and curable cancer if caught early. It’s recommended that you do monthly self-check exams from head to toe to look at moles and any other abnormalities on the skin. But aside from monitoring spots throughout your body, there are other subtle signs of skin cancer you may be ignoring.</p> <p>We asked dermatologists to tell us what skin cancer symptoms people might miss.</p> <p><strong>Skin growths or moles that aren’t brown or black</strong></p> <p>While you might focus on brown or dark moles when you think of skin cancer, there are actually several types of skin growths to keep an eye on. The major types of skin cancer are basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and melanoma. Both BCC and SCC are known as non-melanoma skin cancer or keratinocyte cancers, says Cancer Council Australia.</p> <ul> <li>BCC is the most common type of skin cancer. It often has no symptoms and tends to grow slowly without spreading to other parts of the body. Symptoms include a pearly lump or a scaly dry area.</li> <li>SCC is the second most common form of skin cancer. Symptoms may include thickened red, scaly spots; rapidly growing lump; looks like a sore that has not healed; and may be tender to touch.</li> <li>Melanoma is the rarest but the deadliest form of skin cancer. Often melanoma has no symptoms, however, the first sign is generally a change in an existing mole or the appearance of a new spot. Melanoma is projected to be the third most common cancer diagnosed in Australia, which along with New Zealand has the world’s highest incidence rate for melanoma.</li> </ul> <p>The tricky part is recognising trouble, says surgical and cosmetic dermatologist Dr Adele Haimovic. Some melanoma moles can actually be skin-coloured or pink – they’re known as amelanotic melanomas. This kind of melanoma is a challenge to recognise because we’re inclined to think it’s just a harmless bump. That’s why it’s important to have regular skin checks by a dermatologist to look at any skin growths or abnormalities.</p> <p><strong>Shaving nicks</strong></p> <p>If you find yourself bleeding after shaving, it may not be due to clumsiness: “Basal cell carcinoma and squamous cell carcinoma can bleed after shaving or other minor trauma, and sometimes spontaneously bleed with no known inciting event,” says Dr Haimovic. “This is because skin cancer leaves the skin more fragile than healthy skin.” If you find yourself bleeding in the same spot, get it checked out.</p> <p><strong>Your family tree</strong></p> <p>Having a first-degree relative with melanoma approximately doubles an individual’s risk of developing melanoma, according to the Royal Australian College of General Practitioners (RACGP). Having relatives who have multiple melanomas or who are diagnosed at a younger age further increases the risk of developing melanoma.</p> <p><strong>A pimple that doesn’t go away</strong></p> <p>“Basal cell carcinoma may look like a translucent, skin-coloured or pink pimple that does not resolve or recurs in the same spot,” says Dr Haimovic. Usually, pimples go away on their own in two to three weeks; if one sticks around longer than that, it should be evaluated by a dermatologist.</p> <p><strong>A dark band on your nail</strong></p> <p>If you notice a fairly defined, dark vertical line on your fingernail or toenail, you might think you banged the nail. Take a closer look: “If the band has multiple different shades of brown and black, that is a concern. Also, if the width of the band is greater than three millimetres, that is another concerning feature,” says dermatologist Dr Steven Wang. Although there are other causes (such as an injury), a dark vertical line can sometimes be a sign of a melanoma, so make sure to ask your doctor to take a look.</p> <p><strong>One of your moles is not like the others</strong></p> <p>“A reddish- or light-brown-coloured mole in a sea of dark moles is what dermatologists call ‘the ugly duckling sign,’” says Dr Wang. Basically, one of the moles doesn’t belong in the group or doesn’t look like the others, so it could be a sign of melanoma. If you have a dominant mole pattern on your back and it’s disrupted by a darker, larger mole, it could be an ugly duckling sign. Another example: You have two patterns of small and dark moles on your back, but there’s a smaller, pale mole. The only way to confirm if this is a malignant melanoma is to have it checked by a dermatologist.</p> <p><strong>You’ve had PUVA treatments</strong></p> <p>Psoralen and UV-light treatments (PUVA) are a type of ultraviolet radiation treatment for severe skin conditions such as psoriasis and dermatitis. A previous study published in the Journal of the American Academy of Dermatology found an increased risk of malignant melanomas 15 years after a patient’s first PUVA treatment. In fact, patients who have had 250 or more treatments have five times the risk of people who have never had PUVA.</p> <p><strong>You’ve had an HPV infection</strong></p> <p>There are many forms of human papillomavirus (HPV), with some increasing the risk of cervical cancers. But other kinds of HPV (there are more than 100 in this family of viruses) can cause warts on the skin, often the hands or feet.</p> <p>It’s thought that these skin wart-causing viruses may also increase the risk of non-melanoma skin cancers. In a 2012 study published in the American Journal of Epidemiology, the participants with antibodies against certain types of HPV had a higher risk of developing non-melanoma skin cancer.</p> <p><strong>Your immune system is weak</strong></p> <p>People with weakened immune systems because of disease or certain types of treatment can have a higher risk of skin cancer. HIV/AIDS and lymphoma patients may have an elevated risk, according to the American Cancer Society. This is also true of people who get chemotherapy or other medications that suppress immunity.</p> <p><strong>You have the XP gene</strong></p> <p>Xeroderma pigmentosum (XP) is a rare inherited disorder. According to the Genetics Home Reference, it’s estimated that about one in one million people have it. People with the disorder have an extreme sensitivity to ultraviolet rays from the sun. The gene limits the skin cells’ ability to repair damage to their DNA. According to the American Cancer Society, people with XP have a high risk of developing melanoma and other skin cancers when they are young – when the condition usually reveals itself – especially on the eyes and sun-exposed areas.</p> <p><strong>You work with industrial chemicals</strong></p> <p>People who work in the fields growing produce, in steel and iron foundries, or in coal and aluminium production plants have a higher risk of skin cancer, according to a 2014 study published in BioMed Research International. Also at risk are people who work with industrial carcinogens. These include arsenic – used in pesticides – and polycyclic aromatic hydrocarbons – which are in raw paraffin, creosote, chimney soot, asphalt, shale oil, tar and pitch, and even diesel-engine exhaust fumes.</p> <p><strong>You already had skin cancer</strong></p> <p>Just because you’ve had a squamous cell carcinoma or another type of skin cancer removed doesn’t mean you can relax – if anything, you should be more concerned. SCC recurrence is relatively common on the ears, nose and lips; it typically occurs during the first two years following surgery. In fact, having any type of skin cancer makes it more likely that you will develop another type of skin cancer. “During your regular skin check, your dermatologist will examine old scars to make sure there is no evidence of the cancer returning,” says Dr Haimovic.</p> <p><strong>Stay vigilant</strong></p> <p>Dermatologists recommend that you do a monthly self-check of your moles and any other skin abnormalities to help catch trouble early. This will help you keep tabs on any changes. Be on the lookout for moles or lesions that change in colour (including fading), shape or size, or if you’re experiencing pain, itching or bleeding in these areas, Dr Wang advises.</p> <p>If you do have a growth, use the guideline called ABCDE to evaluate it. That stands for:</p> <ul> <li>Asymmetry (melanomas are less likely to be symmetrical),</li> <li>Border (melanoma borders tend to be uneven),</li> <li>Colour (multiple colours aren’t good),</li> <li>Diameter (if it’s the size of pencil eraser or bigger, that’s a red flag), and</li> <li>Evolving (a change in size or behaviour, such as bleeding, itching, or crusting).</li> </ul> <p>The good news is that although skin cancer is a common form of cancer, if detected early it is usually curable.</p> <p><em><span id="docs-internal-guid-c59a899b-7fff-2066-ec88-9d358f744e6a">Written by Lisa Marie Conklin.

Collagen 101: What you need to know about this skin saviour

<p dir="ltr">Collagen is having its moment in the world of beauty and health at the moment, taking the form of tablets, creams, lotions and powders that promise to hydrate skin and reduce signs of ageing, but do these products actually work?</p> <p dir="ltr">Products such as <a href="https://happyhealthyyou.com.au/" target="_blank" rel="noopener">Happy Healthy You’s</a> Happy Collagen powder include benefits for overall skin health, hydration and nutrition, and it turns out that collagen is one of the most abundant proteins found in the human body in our skin, muscles, tendons and bones.</p> <p><span id="docs-internal-guid-fb92fec4-7fff-9ddc-a7c9-d79319e07d45">Renee Grandi, a naturopath, nutritionist and collagen advocate who helped create Happy Collagen, tells <em>OverSixty </em>that collagen is the “body’s scaffolding system”, which is “critical” for the structure of your skin matrix, arteries, digestive tract, uterine/vaginal tissue, cartilage, eyes and bones.</span></p> <p><img src="https://oversixtydev.blob.core.windows.net/media/2022/06/Collagen_I_alpha_chain_98-110_500.png" alt="" width="500" height="500" /></p> <p dir="ltr"><em>Collagen Type I makes up between 60-80 percent of the collagen peptides in our skin’s dermal layers. Image: PubChem</em></p> <p dir="ltr">“Collagen constitutes 95 percent of human skin, so it’s a big deal,” she says. “Collagen peptides are formed from glycine, proline, hydroxyproline and arginine amino acids.”<br />There are even different types of collagen - types I through V being the most common - with types I and III making up a combined 90 percent of our skin’s dermal layers.</p> <p dir="ltr">But, ageing (particularly the onset of menopause), lifestyle habits, and even stress can cause collagen to degrade over time - which is where supplements can come in.</p> <p dir="ltr">“Those that are more likely to need a collagen boost include women going through perimenopause and menopause as this is when collagen production particularly starts to diminish,” Grandi says. </p> <p dir="ltr">“This is due to lowered oestrogen levels and increased adrenal stress/fatigue.</p> <p dir="ltr">“The adrenal glands become the primary source of oestrogen instead of the ovaries during menopause. Unfortunately, when we're stressed and cortisol is heightened, cortisol takes precedence over collagen and oestrogen production. </p> <p dir="ltr">“There’s an average of 2.1% skin-collagen decline for post-menopausal women per year. This can also impact predispositions to accelerated ageing, uterine prolapse, vulvovaginal atrophy, and bone and joint pain. Collagen is essential for women in menopause, especially if you've had a hysterectomy. A collagen supplement is an easy way to ensure you’re getting your recommended intake.”</p> <p dir="ltr"><strong>Food vs skincare</strong></p> <p dir="ltr">Though collagen got its start as a skincare treatment, the protein isn’t well-suited to these kinds of products since it is too large to penetrate the skin, Dr Joshua Zeichner, the director of cosmetic and clinical research in dermatology at New York City’s Mount Sinai Hospital, told <em><a href="https://www.everydayhealth.com/diet-nutrition/what-is-marine-collagen-and-should-you-try-it/" target="_blank" rel="noopener">Everyday Health</a></em>.</p> <p dir="ltr">This is why collagen products nowadays use collagen peptides (hydrolyzed collagen), which is already broken down, making it easier for collagen to be absorbed in a similar way to when we eat it.</p> <p dir="ltr">Some of the food we eat can contain collagen - think bone broths, eggs, octopus and squid - which is broken down into amino acids that circulate in the blood.</p> <p dir="ltr">But, Grandi says supplements can make it easier for people to get the amount of collagen they need every day.</p> <p dir="ltr">“To boost your collagen for therapeutic integrations you would have to eat about 3-4 servings of collagen-rich foods per day,” Grandi explains.</p> <p dir="ltr">“The best practice is to focus on a holistic approach to skincare with strategic diet, lifestyle, product and supplement interventions. </p> <p dir="ltr">“For instance, you need a healthy gut and skin microbiome to achieve such results, it’s so empowering to learn about what goes on behind the scenes of your skin!”</p> <p dir="ltr">However, upping your collagen intake, whether through diet, supplements, or both, Grandi says it isn’t just a matter of consuming every kind of collagen you can get your hands on.</p> <p dir="ltr">“The trend became to have every form of collagen available and the “more collagen the better mentality”,” she says.</p> <p dir="ltr">“In reality, the body only uses type 1 and type 3 collagen to improve the skin matrix which is most abundant in bovine collagen. The body also does not need more than 5 grams per day. Any more simply will not be assimilated by the body.”</p> <p dir="ltr">Grandi adds that this is why products like Happy Collagen stand out from the crowd of other products that aren’t as selective.</p> <p dir="ltr">“We conducted two years of developmental testing of different forms of collagen and the range of supporting skin nutritional ingredients in the formula,” she says. “We also worked with our Happy Healthy You Community and our practitioner team for their feedback.”</p> <p dir="ltr"><strong>Where collagen comes from makes a difference</strong></p> <p dir="ltr">Collagen products can source collagen from one of two sources: marine and bovine.</p> <p dir="ltr">Marine collagen comes from the skin and scales of fish, and tends to contain types I and II, the collagen which is found in cartilage and eye structures.</p> <p dir="ltr">In comparison, bovine collagen contains both type I and III, and is the kind of collagen used in Happy Collagen products.</p> <p><span id="docs-internal-guid-f428b469-7fff-fe15-bc14-01b7671bdc41"></span></p> <p dir="ltr">For women over 50, types I and III can have additional benefits besides improving the skin’s appearance.</p> <p dir="ltr"><img src="https://oversixtydev.blob.core.windows.net/media/2022/06/LisaCurry-Happy-Healthy-You-Happy-Collagen-.jpg" alt="" width="1000" height="667" /></p> <p dir="ltr"><em>Products like Happy Healthy You’s Happy Collagen powder use bovine collagen, which contains types I and III, for maximum benefits for your skin. Image: Supplied</em></p> <p dir="ltr">“Research shows that menopausal women and women suffering from pelvic organ prolapses, vulvovaginal atrophy, genitourinary dysregulation, and painful sex may have significantly reduced levels of collagen type I &amp; III peptides,” Grandi explains. </p> <p dir="ltr">“Type I collagen enhances skin membrane health, wound healing, tissue regeneration, bone, hair, nails, tendons and even your eyes' cornea! Type III is ideal for uterine health, inflammation, cartilage, and cardiovascular integrity. This makes bovine collagen a powerful healing resource for women over 50.”</p> <p dir="ltr">If you are considering introducing collagen supplements into your diet, it’s recommended you seek the advice of a medical professional first.</p> <p dir="ltr">Grandi also advises to add food rich in vitamin C and zinc to “support collagen production and utilisation while taking a collagen supplement”.</p> <p dir="ltr">But, improving your skin health with supplements isn’t just about collagen either, Grandi says.</p> <p dir="ltr">“There is a range of other factors such as digestion, oxidation and stress that need to be addressed in a formula as well.” </p> <p dir="ltr"><span id="docs-internal-guid-b41e82fc-7fff-24db-38e1-f59a2d27ec88"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>

Always do this if you want to avoid dry skin in winter

<p><strong>How to avoid dry skin in winter</strong></p> <p>Ah, winter. ’Tis the season for dry skin, along with potential complications, including itching, flaking, cracking, bleeding, rosacea (redness and inflammation) and eczema flare-ups. There are several reasons for this. First, the air outdoors is drier. Indoor air tends to be parched as well, an effect of heating systems. Seniors need to take extra care, since cumulative sun damage and slower production of natural oils put them at greater risk of dryness. Happily, there’s plenty you can do to combat dry skin in winter.</p> <p><strong>Switch up your shower routine</strong></p> <p>To start, adapt your bathing routine. Piping hot water may feel good, but that’s a sure way to strip away your skin’s natural oils. Use warm water instead, keep your baths or showers short, and apply a generous amount of moisturiser after you dry off. Thick, oily products are especially effective at fighting winter moisture loss, “but don’t despair if you can’t tolerate those due to pore clogging or shininess,” says dermatologist, Dr Bav Shergill. “Even a light moisturiser will give you some protection.”</p> <p><strong>Hand care</strong></p> <p>When it comes to your hands, frequent washing with soap is essential for preventing the flu and other infections, but it leads to dryness. So after you clean them, apply hand cream. If that doesn’t help enough, try a dab of petroleum jelly before bed; you can put on cotton gloves to keep it in place overnight. Wearing mittens or gloves outdoors also reduces damage, since exposure to the frigid air further harms skin.</p> <p><strong>Layer up</strong></p> <p>If you’re prone to winter itch (which is exactly what it sounds like), avoid direct contact with potentially irritating fabrics such as wool or synthetic fibres. “The best approach is to wear several thin layers,” says Shergill. “The one next to the skin could be cotton or a cotton/silk blend, both of which appear to be well tolerated by most people.” Layering lets you adapt to various temperatures during the day, keeping you toasty while avoiding excessive sweating that could trigger itching and scratching in already-irritated skin.</p> <p><em><span id="docs-internal-guid-62168d91-7fff-a6b7-a41f-75d2117cf61f">Written by Samantha Rideout.

New “sweaty” living skin for robots might make your skin crawl

<p dir="ltr">A team of Japanese scientists have crafted the first living skin for robots that not only resembles our skin in texture, but it also repels water and has self-healing functions just like ours.</p> <p dir="ltr">To craft the skin, the team submerged a robotic finger into a cylinder filled with collagen and human dermal fibroblasts - the two main components that make up our skin’s connective tissues. The way that this mixture shrank and conformed to the finger that gave it such a realistic appearance - making for a large leap forward in terms of creating human-like appearances for robots.</p> <p><span id="docs-internal-guid-699f2960-7fff-1b2e-d849-c1bc95a796a9">“The finger looks slightly ‘sweaty’ straight out of the culture medium,” <a href="https://www.scimex.org/newsfeed/this-robots-sweaty-living-skin-that-can-heal-might-make-your-skin-crawl" target="_blank" rel="noopener">says</a> Shoji Takeuchi, a professor at the University of Tokyo and the study’s first author. “Since the finger is driven by an electric motor, it is also interesting to hear the clicking sounds of the motor in harmony with a finger that looks just like a real one.”</span></p> <p><img src="https://oversixtydev.blob.core.windows.net/media/2022/06/robot-finger1.jpg" alt="" width="1280" height="720" /></p> <p dir="ltr"><em>The team submerged the robotic finger into a mixture of collagen and human dermal fibroblasts to create the new skin.
