glycolic acid

A type of alpha hydroxy acid (AHA) that, like other ingredients in the category, can act as a water-binding agent and, when properly formulated, as an exfoliant. In its capacity as an exfoliant, it can help shed dead skin to renew skin’s surface, visibly softening the signs of aging, particularly from sun damage. Glycolic acid is one of the most effective and well-researched forms of AHA.
