Glycolic Acid
Glycolic acid is a type of alpha-hydroxy acid (or AHA) that's derived from sugar cane. When applied to the skin, glycolic acid works to break the bonds between the outer layer of skin cells, including dead skin cell, this action speeds up cell renewal as well as improves skin texture.
