Glycolic acid belongs to the Alpha-Hydroxy Acid family. They can be isolated from sugarcane, sugar beets and pineapple. Glycolic acid is applied topically on the skin to dissolve and weaken the glue that binds the dead skin cells together. This results in the peeling of the outer skin layer which is composed of dead skin cells and the exposure of younger skin cells underneath. The young skin cells have a smoother appearance and more even coloration. The peeling of old skin cells helps unblock clogged pores thus reducing the formation of whiteheads and blackheads. Since glycolic acid is water-soluble, it may not be able to penetrate very oily skin. It is best used in treating acne where blackhead is not an issue.
