Alpha Lipoic Acid

Alpha Lipoic Acid (ALA) is a naturally occurring organosulfur compound and potent universal antioxidant, unique in its ability to function in both aqueous and lipid environments due to its amphiphilic nature. It is notable for its capacity to regenerate other antioxidants such as vitamins C and E, and glutathione, making it exceptionally effective at combating oxidative stress in skin cells. Formulators prize ALA for its anti-glycation properties and its ability to visibly reduce fine lines and uneven skin tone, though its use requires careful formulation at low concentrations (0.1–1%) in acidic, light-protected systems to prevent oxidation and discoloration.
