Alpha-hydroxy Acid

AHAs and skin quality:

improved the skin elasticity, thickness, collagen and may reduce inflammation. In a study by Ditre CM et al, AHAs were used for skin rejuvenation in subjects for an average of 6-months. Study participants applied cream containing 25% glycolic, lactic, or citric acid (common AHAs) to one forearm and a placebo lotion to the other forearm. At the end of treatment, a 25% increase in skin thickness was reported with use of AHAs. Additionally, increased acid mucopolysaccharides (a major component of skin), improved skin elasticity, and increased quantity of collagen were also reported with no signs of inflammation. (2)
