Alpha Hydroxy Acids (Alpha Hydroxy Acids)
Other names: AHA acids, Alpha Hydroxy Acids
Harm score: 1 (Natural substances)
Alpha hydroxy acids (AHAs), also known as Alpha Hydroxy Acids or AHA acids, are a group of natural or synthetic acids commonly used in dermatology and the cosmetic industry. The best known representatives of these acids include glycolic acid, mandelic acid, lactic acid, tartaric acid and citric acid. The name alpha hydroxy acids refers to their chemical structure, where the hydroxyl group is located at the alpha position (i.e. on the first carbon atom) relative to the carboxyl group.
AHAs are primarily used in the manufacture of cosmetic and dermatological products. Due to their ability to exfoliate - remove dead cells from the skin surface - and stimulate skin renewal, they are often included in peeling products, serums, creams, as well as shampoos and conditioners. AHAs can also help treat acne, reduce wrinkles and pigment spots, or improve skin elasticity and hydration. Although they are also found to a small extent in food, their synthetic form is often preferred in the cosmetics industry. The reason for this is greater control over the quality and concentration of the acid in the final product.
