LACTIC ACID Ingredient Spotlight A cids are an intimidating bunch. Just the name itself conjures up thoughts of burns and red raw skin, the kind once depicted on Sex and the City after Samantha booked in for a chemical peel, but acids shouldn’t all be tarred with the same skin-stripping brush. Glycolic Acid might win the popular vote, but it’s Lactic Acid – the most universal skin-smoother – that deserves its moment in the sun. Derived from fermented milk (the kind Cleopatra was thought to bathe in) Lactic Acid dissolves the bonds holding dead and damaged cells onto the surface of the skin to create a smoother, more even complexion but, unlike Glycolic Acid, Lactic Acid has a much larger molec- ular structure, meaning it penetrates the skin at a much slower rate so the chance of an uncomfortable tingling sensation occurring is minimal. Clearing the surface of the skin and the pores of debris is one of the reasons Lactic Acid is a common ingredient in products that treat acne and keratosis pilaris, but it’s also a great entry- level AHA for those new to acids and those with sensitive skin. While Lactic Acid’s exfoliating powers grab most of the attention, its hidden talent is where things get really interesting. It doesn’t shout about it, but Lactic Acid is an excellent anti-aging ingredient. Unlike some acids which can thin the skin, this AHA actually increases dermal thickness and stimulates collagen and Hyaluronic Acid production within the lower layers to help to rebuild ageing skin from all sides. This two-pronged approach to combating fine lines and wrinkles means these common signs of ageing are easily dealt with, resulting in a complexion that looks noticeably smoother and firmer. Who’d have guessed that the secret to youthful skin would lie in the hands of Lactic Acid? We’ve ticked off acne and ageing, so let’s complete the trilogy with hyperpigmen- tation. Lactic Acid can help treat this condition too and, because it’s not as harsh or as irritating as Glycolic Acid, it can be used to brighten and correct all skin tones, including skin of colour. Removing the pigmented cells from the surface of the skin, either through topical products or a Lactic Acid peel, is a tried and tested way to create a more uniform complexion. So next time someone compliments you on your skin and asks what you’re using, smile sweetly and say, “It’s a secret.” ISSUE #08 | 2018 | SkinHealthMagazine.com 25
