Ingredient Spotlight GLYCOLIC ACID W e get it. Acids are intimidating, especially when it comes to using them on the skin. But once you get to know them, you’ll see that they’re not as scary as they first seem. The most popular acid by far is Glycolic Acid, a natural deriv- ative of sugar cane that has been used as part of in-clinic peels since the 1980s. Part of the AHA family (that’s Alpha Hydroxy Acids for those of you who are new to cosmeceuticals) Glycolic Acid works by dissolving the bonds holding dead cells onto the surface of the skin, to make them easier for the skin to discard. What’s so great about that, you may wonder? Well, to stay healthy and youthful, your skin naturally sheds cells constantly throughout the day to make way for new cells that are being formed deep down in the epidermis. In fact, over a 24 hour period, the skin sheds almost a million cells! When this renewal process slows down, dead and damaged cells start to build up, causing the pores to become blocked and making fine lines appear more pronounced. This build up also hinders how effectively your favourite skin care products can penetrate the surface; meaning all those expensive serums and creams can’t reach the cells they need in order to make a difference. By helping the skin to shed obsolete cells, products that contain Glycolic Acid can improve the skin in other ways too. Keeping the pores clear of cell build-up means pimples are less likely to swell up overnight and, because Glycolic Acid lowers the pH of the skin temporarily, acne-causing bacte- ria struggles to survive, further reducing the possibility of developing a nasty breakout. Using Glycolic Acid regularly will also make the skin’s natural cell removal processes much more efficient, so the chance of a significant amount of build-up happening in the future is less likely. But let’s get back to why acids have such a mixed reputation. It’s all down to the strength of the ingredient and how it makes the skin feel. The Glycolic Acid molecule is one of the smallest in the AHA family, so it pene- trates the skin incredibly quickly. This, coupled with its differing pH to the skin, means it causes a mild reaction to take place in the form of visible reddening and a sen- sation that can be described as a mild tickle at best, and a serious burn at worst. To avoid anything that feels uncomfortable, opt for products that contain a low concentration of Glycolic Acid (we’re talking less than 4%) and use them sparingly throughout the week. If you have sensitive skin, use wash-off products, such as cleansers and face masks, instead of creams and toners to get your Glycolic fix. As Glycolic Acid renews the skin, it is im- portant to protect this fresh layer of cells against external damage, especially sunlight, by making sure a sunscreen features prom- inently in your everyday morning routine. No exceptions. ISSUE #05 | 2017 | SkinHealthMagazine.com 25
