Can alpha and beta hydroxy acids benefit mature skin?

Both alpha and beta hydroxy acids (AHAs and BHAs, also known as salicylic acid) benefit mature skin by exfoliating dead skin cells, which reveals fresher-looking skin. Additionally, the help stimulate cell turnover, which slows as we age. AHAs are derived from a variety of fruits, as well as milk and sugar. There is only one beta hydroxy acid, salicylic acid. The primary difference between the two is that AHAs are water soluble only, while BHA is lipid (oil) soluble. This means that beta hydroxy acid is able to penetrate into the pore which contains sebum (oil) and exfoliate the dead skin cells that are built up inside the pore. Because of this difference, BHAs are more effective on oily skin with blackheads. Together, alpha and beta hydroxy acids form a powerful rejuvenator for both congested skin and mature skin.
