Glycolic acid is the smallest member of the Alpha Hydroxy Acid (AHA) family. Over centuries, glycolic acid benefits have become known to boost rejuvenation and enhance skin discoloration through methods of exfoliation and peeling agents. Using glycolic acid for skin pigmentation rejuvenation has also proven to be an effective method for skin brightening.1 In addition, certain glycolic acid products (i.e. glycolic acid lotion, glycolic acid cream) with high enough glycolic acid concentrations have also been shown to treat wrinkles and fine lines 1 2.
