Alpha hydroxy acids (AHAs)

Found in fruit such as grapes and lemons, as well as in sugar cane and milk. Often known as fruit acids, they are used at low concentrations to gently speed up the skin's normal exfoliation process. The result is a shedding of dry surface skin cells and an improved appearance and skin feel. At concentrations higher than used in cosmetic products, irritation and peeling can occur.
