To find out how AHA works for skin care, let us see how the skin grows old, and how to keep it younger. Cells in the outer layers of skin are bound together by inter-cellular fluid. As one ages, this glue-like substance binds the skin cells tighter and denser. Dead skin layers build up and unlike young skin, natural exfoliation becomes difficult. This group of natural acids has the ability to loosen this inter-cellular fluid, and allows the top layer of dead skin to slough off easily. See similar questions...

Alpha hydroxy acids (AHA's) are really a family of acids. Glycolic is the most widely used because of its small molecular structure, but Lactic – which is most beneficial for dry/aging skin, and Salicylic – which is most beneficial for oily/acne prone skin, are very powerful as well, and should be used accordingly. AHA's are one of the safest methods of skin renewal. Their effectiveness depends on the type and concentration of the AHA, its pH (acidity), and other ingredients in the product.
