Since the beginning of time, women and men alike have relentlessly pursued the secret to radiant, younger-looking skin. Cleopatra bathed in sour milk and ladies in the French Court applied aged wine to their faces to keep their skin smooth and blemish-free. The link between these age-old remedies and beautiful, clear skin is a group of naturally occurring fruit acids, collectively referred to as Alpha Hydroxy Acids or AHAs. These mild, organic fruit acids are so named because they are non-toxic and can be found in a variety of fruits and foods, for example: lactic acid in sour milk, tartaric acid in grapes, malic acid in apples and citric acid from citrus fruits.
