Alpha hydroxy acids (AHAs) are a group of natural acids found in foods, including citric acid, glycolic acid, lactic acid, malic acid, and tartaric acid.
Alpha hydroxy acids seem to work by removing the top layers of dead skin cells. They can also increase the thickness of deeper layers of skin, promoting firmness.
People commonly use alpha hydroxy acids in cosmetic products for skin conditions, including dry skin and aging skin. The scientific evidence varies depending on the specific alpha hydroxy acid used.
This is a general review of alpha hydroxy acids as a group. See information on specific alpha hydroxy acids, such as citric acid, lactic acid, glycolic acid, malic acid, and tartaric acid, to learn more.
