Here's the Lowdown on Glycolic Acid, Plus 10 Products That Put It in the Spotlight
If you haven't yet met glycolic acid, prepare to fall in love at first swatch. This superacid falls into the category of "alpha hydroxy acids" — or AHAs — which are naturally derived acids typically found in sugarcane, sugar beets, and fruit. Because a molecule of glycolic acid is smaller than its AHA counterparts (including lactic, mandelic, and citric acids), its particles are better able to penetrate the skin and are considered to be more effective.
"Glycolic acids are often used to treat acne scarring, skin discoloration, and signs of aging such as fine lines and wrinkles," explained Anita Sun, a medical esthetician and the founder of Dermovia. "It is also effective in treating skin conditions such as psoriasis, melasma, seborrheic keratosis, and keratosis pilaris."
In other words, it's really, really ridiculously good at resurfacing the skin. But that's not all!
Sun added, "Glycolic acid helps to boost collagen production and is effective in plumping the skin supporting healthy skin tissue to remain firm and prevents wrinkles from forming. It's also effective in removing surface dead skin cells and removing oil build up in pores."
By incorporating this ingredient into your skincare routine, you'll notice a brighter and more even complexion — sometimes in as little as 24 hours. If you need glycolic acid in your life, we've listed our favorite products ahead.
