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

<div class="theconversation-article-body"><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.<!-- Below is The Conversation's page counter tag.

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.com.au/healthsmart/the-best-skin-care-routine-for-oily-skin-according-to-dermatologists?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

The best anti-ageing secrets dermatologists won’t tell you for free

<p><strong>The best tips from top dermatologists </strong></p> <p>A wide array of over-the-counter anti-ageing skincare products aim to improve the signs of ageing, such as skin spots, fine lines, wrinkles, and boost collagen. Yet, most of these products are more hype – it’s important for consumers to understand when a product is a cosmetic, drug, or both to evaluate the validity of these claims. So, which products can actually deliver results that improve the signs of ageing?</p> <p>We spoke with medical experts who told us the best anti-ageing secrets for better skin health.</p> <p><strong>Opt for sunscreen to fight ageing skin</strong></p> <p>Sunscreen is one of the best weapons when it comes to protecting your skin against skin cancer, and it’s also one of the best ways to keep your skin looking younger and healthier. “The sun emits ultraviolet radiation that damages skin, both the overlying epidermis and the underlying dermis,” explains dermatologist, Dr Jerome Garden. “In addition to increasing your risk of skin cancer, the sun causes brown spots, red spots, and wrinkles.”</p> <p><strong>Expensive products are not always more effective</strong></p> <p>It may be tempting to splurge on a skin-care item that promises to yield worthy results, but pricey doesn’t always equal quality. There are some great inexpensive products that can produce great results, according to dermatologist, Dr Dendy Engelman. “A higher price tag can mean better quality ingredients or a higher concentration of an ingredient, but the ingredients list is always more important than the brand selling the product,” she says.</p> <p><strong>Don't buy generic skincare</strong></p> <p>You don’t need to spend a fortune to get a high-quality skincare product, but there is a difference between a brand name product and a generic one, according to dermatologist, Dr Joshua Zeichner.</p> <p>“Many generic products are packaged to look similar to the original, and may even have the same ingredients list, however, the difference is the quality of the ingredients and how they are actually formulated,” he says.</p> <p><strong>Skimp on a fancy cleanser</strong></p> <p>No matter what an expensive cleanser may cost, it’s not going to work any more magic than most lower-cost competitors, according to dermatologists. “The goal of a cleanser is to remove dirt, oil, makeup and pollution from the skin without disrupting the outer skin layer – and the ingredients used to create a product that can do this are not expensive,” says Dr Zeichner. “In fact, some of the best quality cleansers are actually among the least expensive products on the market.”</p> <p><strong>Opt for a serum</strong></p> <p>Serums, which are meant to be layered underneath your daily and nightly moisturiser, often are the first skincare products to be skipped. But, they actually play an important role in your daily routine. “Serums contain a high concentration of active ingredients and are lightweight, so they penetrate deeper into your skin to provide maximum benefits,” says dermatologist, Dr Whitney Bowe.</p> <p>She recommends looking for serums that contain ceramides and amino acids, which help to bolster the skin’s natural barrier, and antioxidants, which protect skin from sun damage and free radicals.</p> <p><strong>Don't trust anti-wrinkle face cream claims </strong></p> <p>“We develop fine lines because of repeated folding of the skin from underlying muscles,” explains Dr Zeichner. “Young, healthy skin has a strong foundation that resists folding and bounces back to its original shape, but, with age, that skin foundation gets weaker.”</p> <p>While topical creams will certainly help keep the skin barrier strong, the only way to truly reduce wrinkles is to relax the muscles underneath the skin, according to Dr Zeichner.</p> <p><strong>Wear sunscreen year-round</strong></p> <p>It’s true that even on the cloudiest or snowiest of days, sunscreen should be a part of your daily skincare routine. “Incidental sun exposure for only 10 to 15 minutes a day adds up over time and can cause significant sun damage and accelerated photoaging,” says Dr Engelman.</p> <p>In order to keep skin looking its youngest and healthiest, she recommends applying sunscreen every single day of the year, as brief sun exposures throughout the year can add up to significant damage (think driving with the sunroof open or walking around outdoor shopping centres during peak sun hours).</p> <p><strong>Use retinol - it really works</strong></p> <p>According to dermatologist, Dr Hadley King, topical retinoids are the most effective topical anti-ageing products (after sun protection). “There is great data that supports their effectiveness and safety,” she says. “While prescription retinoids are the most effective, there are now plenty of over-the-counter products that contain retinol and work well, especially on those with sensitive skin.”</p> <p><strong>Invest in laser treatments</strong></p> <p>If you’re looking for fast results without the use of creams, Dr Garden recommends laser treatments, which he specialises in. “We have lasers for brown spots, red spots, blood vessels and wrinkles,” he says. “Newer devices called fractionated lasers can produce impressive results with less downtime than before.” Although they’re on the pricier side, he says that these treatments can offer results far superior to creams.</p> <p>But the only caveat is that these machines are powerful and, in many states, can be operated by unqualified individuals who are not even physicians. He recommends making sure that your laser treatments are being performed by a board-certified dermatologist to avoid complications.</p> <p><strong>Try collagen supplements </strong></p> <p>Collagen is a protein that’s a building block for our hair, skin and nails. “Supplemental collagen is fragmented pieces of amino acids and peptides that connect in the bloodstream with enzymes that trigger the production of collagen,” explains Dr Engelman. “In a collagen-deficient system, this will support and increase collagen production.” It’s important, however, that you choose the right type of collagen, since 16 different strains exist.</p> <p>“For oral supplements, hydrolysed collagen is easiest to digest, as it is broken down into the smallest forms of peptides and amino acids,” she says. “I like pills and powders because they are easy to incorporate no matter what your lifestyle.”</p> <p><strong>Don't fall for 'trendy' products</strong></p> <p>The latest and greatest products on the market might be eye-catching, but their popularity doesn’t mean that they’re effective. “Just because something is ‘hot’ right now in the beauty industry, does not mean that you should run out to purchase it,” says Dr Bowe. “I always encourage my patients to look for scientific studies and statistics which prove that products deliver the results they promise.”</p> <p><strong>Follow a healthy diet</strong></p> <p>No matter how much time, energy and money you spend on your skincare regimen, if you’re not supplementing it with a healthy diet, you’re wasting your efforts, according to experts. “Your skin is a reflection of your overall health and wellness and your diet absolutely impacts the appearance and health of your skin,” says Dr Bowe.</p> <p>“For example, sugar in any form causes multiple changes in our body, from our cellular membranes and our arteries to our hormones, immune systems, gut, and even microbiome – the microbes in our intestines that affect our biology all the way out to our skin.”</p> <p><strong>Allergy pill and a nap may reduce dark circles and puffy eyes</strong></p> <p>There are other causes of dark circles that are unrelated to your skin, such as seasonal allergies or lack of sleep. Dermatologist, Dr Joel Schlessinger recommends trying Clarityne or Zyrtec, drinking more water, or heading to bed an hour earlier to clock in more sleep. If your dark circles and puffiness aren’t improved by any of those suggestions, then he says a well-formulated and hydrating eye cream could help.</p> <p><strong>Avoid sleeping on your side</strong></p> <p>Believe it or not, the way you sleep does have an effect on the smoothness of your skin. “Sleeping on your side presses your cheek into the pillow and causes the skin on your chest to be scrunched, creating new or reinforcing existing wrinkles,” warns Dr Schlessinger. “Train yourself to sleep on your back as much as you can – it will keep skin as flat and smooth as possible.”</p> <p><strong>Don't wait until it's too late too start Botox</strong></p> <p>Some fine lines and wrinkles are caused by repetitive movements, so starting these treatments early, even in your late 20s and early 30s, may potentially help prevent them or slow their progression, according to cosmetic dermatologist, Dr Sejal Shah.</p> <p>“People are often afraid of injectables because they don’t want to look ‘frozen’ or overdone, but many neurotoxins (Botox, Dysport, Xeomin, and Jeuveau) can look very natural when appropriately placed.” Just be sure to seek treatment from trained individuals, such as a board-certified dermatologist.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/beauty/the-best-anti-ageing-secrets-dermatologists-wont-tell-you-for-free?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

8 things dermatologists wish women knew about cellulite

<p><strong>What is cellulite?</strong></p> <p>Cellulite is the term for lumpy, dimpled flesh on the thighs, hips, buttocks and abdomen. It can also appear on the arms and breasts. “Cellulite is enlarged packets of body fat deep beneath the skin pushed against the vertical connective tissue that surrounds fat cells,” says dermatologist, Dr Dendy Engelman.</p> <p>“When the fat cells expand, it limits the space under the skin and puts pressure on the connective tissue. The pressure forces the fat against the top layers and creates the dimpled look.” So, before you try the latest and sometimes unfounded cellulite treatment, our skin experts explain what you need to know.</p> <p><strong>Almost every woman has cellulite</strong></p> <p>“Cellulite is very common – 93 per cent of women have it,” says Dr Engelman. “The first thing women with cellulite need to know is that they aren’t alone,” echoes dermatologist, Dr Bruce Katz. “The vast majority of women have at least some of these dreaded pockets of fat.”</p> <p><strong>Cellulite is harmless and not a disease</strong></p> <p>Although we may not like how it looks, cellulite is a completely normal and benign condition. “Cellulite is not the disease the media would have us think,” says dermatologist, Dr Tanya Kormeili. Cellulite doesn’t hurt, and it also doesn’t affect overall physical health.</p> <p><strong>Exercise can help reduce cellulite</strong></p> <p>“Since cellulite is fat, excess fat can contribute to the appearance of cellulite. Increasing muscle tone and exercising can minimise cellulite,” says Dr Engelman. Dr Katz agrees: “Generally, the key to alleviating cellulite is weight loss combined with building muscle. Muscle lies below the pockets of fat that strain against the skin and create cellulite. Smoothing the muscle should lead to smoother skin. Most women carry cellulite in their thighs and buttocks, so workouts emphasising leg lifts, squats and lunges tend to be most effective.”</p> <p>Dr Katz says that in his experience, lifestyle changes alone aren’t enough to reduce cellulite to most women’s satisfaction. Some cellulite treatments are nonsurgical and require very little downtime.</p> <p><strong>Diet can also affect cellulite appearance</strong></p> <p>Having a healthy diet is a positive for your body in general but may also reduce the appearance of cellulite. “Antioxidants and omega-3s can be a woman’s best friend in fighting cellulite because they help break fat cells down and strengthen the skin and connective tissue, respectively,” says Dr Katz.</p> <p>“I recommend foods like flaxseed, dark berries and salmon. Many women patients are also overjoyed to learn that they don’t have to cut out chocolate. Natural cocoa is loaded with antioxidants, so dark chocolate is a welcome part of any anti-cellulite diet.”</p> <p><strong>Cellulite has a genetic component (woman of any size can have cellulite)</strong></p> <p>Women who have cellulite tend to have mums, sisters and aunts with cellulite no matter what their body size or shape. Dr Katz says, “One of the biggest misconceptions about cellulite is that losing body fat alone will reduce its appearance. I have treated cellulite in women who are marathon runners and triathletes who still have cellulite. I treated one woman who did the Ironman triathlon in Hawaii four times and still came in to have her cellulite treated.”</p> <p>Dr Engelman echoes this by saying, “Cellulite is genetic, so while weight can influence the presence of cellulite, even the thinnest women can have it.”</p> <p><strong>Men rarely get cellulite because of their skin structure</strong></p> <p>Men, on the other hand, are unlikely to have cellulite; according to the Cleveland Clinic, less than 10 per cent of men are affected by it.</p> <p>That’s because the support tissue in a woman’s body is softer, likely because women’s bodies have to stretch so much to accommodate a growing baby. Visualise fishnet pantyhose – this is what women’s covering of skin looks like versus men’s covering, which is more like a thick, uniform pantihose holding all the fat in place and not allowing as much herniation.</p> <p>“This is an anatomical issue with our bodies as women. Not our fault! Biology! As we get older or under the effects of hormones, the fishnet ‘holes’ can get even more permeable with more herniation, and hence cellulite forms,” says Dr Kormeili. “Therefore, creams and fads can’t really correct cellulite unless they could go deep in the skin and repair the fishnet into a thick pair of pantyhose,” she says.</p> <p><strong>Be wary about expensive "miracle" cellulite treatments</strong></p> <p>We’ve all seen the super expensive creams and potions that claim to erase cellulite – but are they worth it? “While many treatments claim to be able to improve the appearance of cellulite, the long-term effectiveness of these treatments or their true efficacy is still being investigated.</p> <p>So, please, don’t waste your hard-earned money on claims that won’t really yield the results you want,” says Dr Kormeili. If cellulite is a true concern, it’s best to contact a board-certified dermatologist to discuss your options as there are several treatments that can help but they require a physician’s intervention.</p> <p><strong>Caffeine may improve skin's texture</strong></p> <p>“Most cellulite-fighting creams contain caffeine as their active ingredient, which can be more helpful than you’d imagine when applied religiously,” says Dr Engelman. “This is because of the temporary effects caffeine has on the body, which are actually prolonged to daily effects. It shrinks fat cells by dehydrating them.”</p> <p>Dr Engelman suggests applying these creams with an aggressive massage or a rolling motion to help aid in the penetration and see better results.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/beauty/8-things-dermatologists-wish-women-knew-about-cellulite" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Got lip lines? Here’s what a dermatologist would do

<p><strong>How you got wrinkles around your mouth</strong></p> <p>Even if you never smoked in your life, you can develop fine lines around the mouth from sipping through a straw, whistling a tune, pursing your lips in frustration, or even overdoing it on those duck-face selfies. Even speech patterns which involve frequent pursing of the lips can contribute. “Minor lips lines are caused by ageing and sun damage,” explains plastic surgeon, Dr Norman Rowe. “Larger lips lines are caused by muscle overactivity.” Regardless of the cause, top cosmetic doctors have more tools than they’ve ever had to help delete your lip lines and prevent them from coming back.</p> <p><strong>Neuromodulators</strong></p> <p>For fine, moderate (not too deep) lip lines, neuromodulator injections such as Botox, Dysport, or Xeomin can often paralyse them into submission, says cosmetic surgeon, Dr Joe Niamtu. “This helps relax the muscle tension around the mouth and makes a small but generally noticeable difference.” “Prejuvenation” is a big buzzword in aesthetics today, and it has a role to play in staving off severe lip lines, adds dermatologist, Dr Joel Cohen. “If I see patients in their 20s and maybe early 30s, and I use Botox, Dysport, or Xeomin in low dosages to soften the muscles, these columns are less prominent, less deep, and less likely to imprint the skin.” Some effects are visible immediately, but it can take up to two weeks for these neuromodulators to fully kick in. Results last anywhere from two to four months. Cost varies by the amount needed.</p> <p><strong>Fillers</strong></p> <p>For deeper static lines, hyaluronic-acid based dermal fillers are the way to go, says plastic surgeon, Dr David Shafer. Hyaluronic acid is found naturally in almost every cell in our body (especially the skin), but our supply tends to dwindle with advancing age. “Some hyaluronic acid fillers – Juvederm and Restylane – can provide volume to plump the lip, while others – Volbella, Restylane Silk, and Belotero – are much thinner and can help fill lines without adding as much bulk,” he says. “Since the lips lose volume with age, I often suggest a combination of natural plumping and line filling.” For people who have mild lines in the upper lip, Dr Cohen injects the filler very superficially so it blurs them. He also likes to pretreat the area a week or two earlier with a little bit of Botox, Dysport, or Xeomin to soften that musculature. Cost is based on the type of filler, amount needed, and often the location of the medical practice. Exactly how long results last also varies by product. Another option for those who hate needles: Fillerina Replenishing Treatment, a gel composed of six hyaluronic acids that is released via a pen-like applicator to fill in fine lip lines.</p> <p><strong>Lasers, lights and peels</strong></p> <p>Patients with fine lip lines and an aversion to needles have other options as well, Dr Shafer says. “The outer layer of the skin can be treated with superficial treatments such as laser resurfacing, radiofrequency energy, chemical peels, micro-needling, dermabrasion and other such treatments,” he says. These treatments all remove the skin’s uppermost layer, getting rid of dead skin cells and making room for new, healthier ones. “Treating the superficial layer helps improve skin texture and colour and soften very fine static lines.” These treatments are quick and relatively pain-free with numbing cream, and there’s minimal recovery depending on the type of treatment and how aggressive it is. Peels and laser treatments will cause several days or more of redness, which you can conceal with makeup, he says. A series of treatments are typically needed for optimum results. “For deeper etched lines, I like to use full-field erbium resurfacing lasers, which is done to a very deep level,” Dr Cohen says. The downside? There’s some downtime with this aggressive procedure, he says. The upside? It’s often one and done, meaning there’s no need to come back for more treatments. “I often pre-treat these patients a week or two before with Botox or Dysport just to decrease the mechanical action of that underlying muscle contracting for a synergistic result,” he adds.</p> <p><strong>PRP: the newest kid on the block</strong></p> <p>Platelet-rich plasma (PRP), a substance in our own blood that is rich with growth factors, is being used to treat hair loss, orthopaedic injuries, and more, including lip lines. “PRP injections stimulate new collagen formation like spackling,” says New York City facial plastic surgeon Sam Rizk. Collagen is the main building block of healthy youthful skin, and as we age, our natural supply diminishes. “PRP works well for smoker’s lines because it fills in the lines from the inside out. I use a combination of PRP and laser resurfacing for a one-two punch,” Dr Rizk says. He typically recommends three treatments, spaced four to eight weeks apart, and often sees visible improvement in the first month. If you’re leery about needles and fillers, think about a light resurfacing laser like Fraxel.</p> <p><strong>An ounce of prevention …</strong></p> <p>The procedures outlined here can help eliminate lip lines once you have them. Even better? Preventing them from developing in the first place. “Protecting your lips from the sun, always using sunblock, not smoking cigarettes, and getting preventive Botox will slow down the formation of these lines,” says Dr Rowe.</p> <p><em>Written by Denise Mann.

8 summer skincare tips dermatologists follow

<p>For the key to keeping your skincare optimal during the summer months, try these 8 things dermatologists do every summer.</p> <p><strong>1. Lose old layers</strong></p> <p>Twice a week, scrub skin with a soft brush, an exfoliating scrub, or a salicylic acid wash to brighten it and allow lotions and serums to be absorbed more deeply. If your skin becomes irritated, exfoliate just once a week.</p> <p><strong>2. Cleanse without cream</strong></p> <p>As the weather warms, switch from a cream cleanser to a gel variety, which is lightweight yet still effective. If you have oily skin, try a foam cleanser. Be sure to wash your face every night in the summer. More time outside means more exposure to harmful air pollutants, which can attach to moisturiser and make-up and exacerbate the signs of ageing.</p> <p><strong>3. Lighten the lotion, too </strong></p> <p>Heavy creams contain lipids that can cause clogged pores and pimples in more humid months. Instead, opt for serums, lotions or hydrating gels, which are all lighter.</p> <p><strong>4. Strategise sunscreen </strong></p> <p>In the morning, before you apply your make-up, slather on a sunscreen that is at least SPF 30. Reapply sunscreen every two hours if you’re outside. If you’re worried about smearing make-up, use a mineral sunscreen powder that is easy to reapply throughout the day. Be aware that moisturisers that contain sunscreen are not as effective as sunscreen itself.</p> <p><strong>5. Consider covering up </strong></p> <p>Each centimetre on a hat’s brim increases coverage of your face by four per cent. Working or exercising outside? Wear sun-protective clothing. Look for a swing tag with a high ultraviolet protection factor (UPF 50+) rating to be sure. You can cut exposure further by heading outdoors before 10am or after 4pm.</p> <p><strong>6. Be wary of clouds </strong></p> <p>Sunburn can still occur on cloudy days, when cooler air persuades you to skip sunscreen. However, clouds block only about 20 per cent of the sun’s UV rays. Apply sunscreen as you would on sunny days.</p> <p><strong>7. Remember the sly spots </strong></p> <p>A surprising number of skin cancer cases occur behind the ears and on other areas that you may ignore when applying sunscreen. Cover your ears, the tops of your feet and your hands for full coverage.</p> <p><strong>8. Eat for sun protection </strong></p> <p>Studies show that certain foods may offer an extra level of UV protection from within or reduce the risk of skin cancer. Foods high in antioxidants (colourful fruits and vegetables, such as cherries, citrus fruits and pomegranates), Swiss brown mushrooms, green tea, nuts, probiotics (Greek yoghurt with live active cultures and kombucha, a fermented tea) and oily fish (such as salmon) are all star performers.</p> <p><em>Written by Kelsey Kloss.

Dermatologist reveals the shocking reason why you must wash new clothes

<p>While many agree that it is a good idea to wash your new clothes before wearing them, sometimes due to the sheer business of life it can be an ambition that gets pushed down the priority list.</p> <p>However, you might want to rethink this decision now that a dermatologist has revealed the shocking reason why you should always wash your new clothes before wearing them.</p> <p>According to Donald Belsito, a professor of dermatology at Columbia University Medical Centre, wearing shop-bought clothes without washing them could lead to irritation, scabies and even fungus.</p> <p>In an interview on the<em> Today</em> show, the expert explained that clothes have most likely been tried on by multiple shoppers before they land in your wardrobe.</p> <p>“I have seen cases of lice that were possibly transmitted from trying on in the store, and there are certain infectious diseases that can be passed on through clothing,” Belsito said, according to <span style="text-decoration: underline;"><em><strong><a href="https://www.apartmenttherapy.com/should-you-wash-clothes-before-wearing-255584" target="_blank">Apartment Therapy</a></strong></em></span>.</p> <p>“The other infestation I've seen from clothing is scabies.”</p> <p>He explained that it’s better to not “take any chance” and to thoroughly clean clothes that have been bought in store.</p> <p>New garments often have chemicals and preservatives to help keep them fresh during shipping, which can cause skin irritation.</p> <p>Formaldehyde resin, which is applied to some clothes to stop them from wrinkling, can cause eczema and dermatitis.</p> <p>It has also been linked to skin irritation and allergic reactions, while some scientists say it can increase the risk of cancer.</p> <p>Do you always wash your new clothes before wearing them?
