| glycolic acid |
Natural fruit acids (alpha hydroxy acids or AHAs) rejuvenate the skin by encouraging the shedding of old, sun-damaged surface skin cells. Glycolic acid is the alpha hydroxy acid most frequently used for facial treatments but lactic and citric acid are also useful. Of course, lactic acid doesn't come from fruit - it comes from milk.
