Q. I’ve noticed that my skin is much drier and thinner than it used to be. I regularly exfoliate and do at home peels. Could these be thinning my skin?

No. The layers of skin get thin by sun damage and ageing. However over-cleansing the skin or using harsh exfoliators can harm the skin. Your skin naturally acts as a barrier, meaning it keeps out what it’s supposed to (dirt and free radicals like environmental pollution) while keeping in the good stuff (moisture and some oils). When you over-cleanse your skin, you can strip your skin of the oils that keep skin healthy and balance so it feels taut and tight. Use a gentle cleanser like Cetaphil Gentle Skin Cleanser (£7.19 boots.com) and only use a scrub once a week. To improve dry skin there is a new treatment called Profhilo, which is designed to hydrate your skin from the inside out, using moisture boosting hyaluronic acid. The treatment takes around ten –minutes and involves having five tiny injections at special points on each side of the face but instead of going deep into the tissue, the injections are placed underneath the surface of the skin .The hyaluronic acid then gradually spreads through the surrounding tissues over the following weeks when you will see a radiant glow, a much improved skin tone and texture and healthy plump skin. Two sessions are necessary for the best results. There is no downtime, and results last up to nine months Expect to pay around £500  – for more info 0207 436 4441
