Alpha-hydroxy acids occur naturally in several foods types. These are better known to us as citric from fruits, malic from apples and lactic from milk.  Glycolic Acid is also well known  nd it comes from the sugarcane.
A natural exfoliating process takes place when any of the acids are applied to the skin by loosening away the outer layer of dead skin which is then sloughed away.
After this process takes place new cells are generated and they reveal, smoother skin and a healthier complexion.
