It is an alpha-hydroxy which can be used as a chemical face peel. Its small molecular structures allows it to penetrate the skin easily. It acts as an exfoliant removing dead skins cells from the skin's surface and fights acne as it absorbs into the sebaceous follicules and removes buildup that clogs pores. It is also an excellent hydration agent.
