Hyaluronic Acid for Acne Treatment: What It Can Do for Your Skin - Jordan News
If acne is one of your biggest beauty concerns, chances are you've tried everything—from home remedies to conventional treatments—and probably spent a lot on oil-free, non-comedogenic skincare products. But today, the solution might be simpler than ever. Hyaluronic acid, a naturally occurring substance in your skin, is proving to be a direct and effective approach to acne care. اضافة اعلان What Is Hyaluronic Acid? Hyaluronic acid (HA) is a naturally occurring substance found in your skin, connective tissues, and joints. Its main job? Keeping your skin hydrated. HA binds to water molecules and can retain up to 1000 times its weight in water, making it a go-to ingredient in serums, creams, and moisturizers. As you age, the natural levels of HA in your skin decrease, leading to dryness and loss of elasticity. For acne-prone skin, dryness and a compromised skin barrier are common problems—especially because many acne treatments (like benzoyl peroxide, salicylic acid, and retinoids) strip the skin of moisture and oils, often leaving it irritated and overly dry. When this happens, your skin can overcompensate by producing more oil (sebum), leading to clogged pores and more breakouts—a frustrating cycle. Here's How Hyaluronic Acid Can Help: 1. Provides Deep Hydration HA delivers essential hydration without clogging pores. Unlike thick moisturizers that can trap oil and dirt, HA is lightweight—it attracts and retains moisture without leaving a greasy film. It also helps regulate your skin's oil production and maintains a healthy balance—both of which are crucial in preventing breakouts. According to a 2017 study published in the Journal of Investigative Dermatology, proper hydration can help reduce excess sebum and acne formation. 2. Soothes Redness and Irritation For many people with acne, redness and irritation are just as troubling as the breakouts themselves. HA has anti-inflammatory and wound-healing properties that calm the skin and promote a more stable, less reactive environment, as noted in a 2021 study published in Biomolecules. 3. Boosts Absorption of Other Ingredients Properly hydrated skin absorbs active ingredients—like retinoids or salicylic acid—more effectively. When used alongside HA, these treatments are less likely to dry out or irritate the skin, allowing for more targeted and efficient results. 4. Helps Heal Acne Scars HA can also help improve the appearance of acne scars. A 2018 study in Dermatologic Surgery found that HA fillers were effective and safe for treating atrophic acne scars. Hydrated skin heals faster, which means incorporating HA into your routine can help scars fade sooner. Does Hyaluronic Acid Cause Acne? While HA does not cause acne, certain formulations that mix HA with heavy oils or comedogenic agents can trap dirt and bacteria, leading to breakouts. Also, applying HA on dry skin without sealing it with a moisturizer can sometimes draw moisture from deeper layers, causing dryness and increasing oil production—potentially worsening acne for some people. How to Use Hyaluronic Acid for Acne-Prone Skin To get the most out of HA, use it correctly: Apply on Damp Skin: HA draws in moisture, so always apply it to damp (not dry) skin to avoid dehydration. After cleansing, gently pat your face so it remains slightly moist. Use a Serum First: Apply a few drops of an HA-based serum to your damp face. Lock in Moisture: Follow up with a non-comedogenic lightweight moisturizer to trap the hydration inside your skin. Pair with Acne Treatments Carefully: You can use HA before or after acne treatments like benzoyl peroxide or retinoids. If your routine includes multiple actives, apply HA first to create a calming moisture base and reduce irritation. If your skin feels too dry, layer HA on top of your acne treatments to form a protective barrier. Show Related News Show Related News

Longevity Expert Says 1 Fingernail Sign Shows How You're Ageing
You might already know that your fingernails can reveal a surprising amount about your health status, showing signs of everything from anaemia to, in some rare cases, a form of melanoma. But according to Dr David Sinclair, a Harvard-based expert in ageing and genetics who's known for his research into longevity, they can tell us how we're ageing too. In 2022, the doctor explained on a podcast that one sign on our hands 'is a really good indicator of how you're ageing or not ageing.' It's based, he explains, on a 1979 study. Our nails do not grow as quickly when we're older as they did in our younger years, the doctor explained. 'Every time I have to cut my nails, I'm thinking, 'How long ago did I cut my nails?'', he commented. He pointed to a 1979 study in which researchers attached tape to people's nails and measure how much they grew in different populations over a set period of time. This paper, published in the Journal of Investigative Dermatology, found that, 'The rate of linear nail growth decreases 50% over the life spans of both dogs and humans.' As Dr Sinclair points out on the podcast, the study showed that the rate was about 0.5% each year after the participants' 30th birthday. A 2011 study put the start point even earlier, at 25 years of age. While the professor admits that he doesn't pay much attention to his own nail's growth, he adds: 'If you measure that, it's a really good indicator of how old you are biologically.' According to Healthline, it may have to do with blood flow, which slows over time. Previously, Dr Michelle Henry, founder of Skin and Aesthetic Surgery of Manhattan, told HuffPost that, 'As we age, our bodies start to produce less of the natural proteins found in nails, which can lead to nails becoming more brittle, dry, and prone to breaking.' He added: 'These keratin proteins are also found in our hair follicles, which is why we may also see a change in our hair texture as we age.'
