Using an exfoliant with glycolic acid for your face results in a brighter, more even toned complexion. Like all AHAs, glycolic acid works by helping turn over spent cells on skin’s surface. This type of exfoliation addresses numerous skin concerns, including sun damage, uneven tone, rough, flaky patches of skin, fine lines, and wrinkles. In higher concentrations, glycolic acid can even improve the look of deeper wrinkles.
