Alpha Hydroxy Acids

Alpha hydroxy acids (AHAs), are generaly considered to be one of the cornestones of medical grade skin care (cosmeceuticals and chemical peels). The AHAs most commonly used in cosmetic applications are commonly called fruit acids (including lactic acid, glycolic acid and citric acid). AHAs have an effect on the superficial (epidermal) and deeper (dermal) layers of the skin. At the epidermal layer they encourage regeneration of the stratum corneum. This is caused by a shedding of the existing corneocytes. At the Dermal layer they have been shown to produce increased amounts of mucopolysaccharides and collagen and increase skin thickness without detectable inflammation. Peels containing AHAs reduce fine wrinkling, treat areas of dryness, reduce uneven pigmentation, aid in the control of acne, smooth rough dry skin and improve the texture of sun-damaged skin.” ”>
