Alpha hydroxy, or alpha hydroxy acid, is a group of organic carboxylic compounds that are commonly used in cosmetic products (cosmeceuticals). The Federal Drug Administration (FDA) warns that regular use of alpha hydroxy increases photosensitivity to the sun.
Function
Alpha hydroxy exfoliates the skin and removes dead skin cells. Alpha hydroxy also controls the skin's oil production.
Benefits
As a result of using alpha hydroxy, fine lines and wrinkles are minimized. It also evens out skin tone and softens skin's rough, dry texture.
Types
Alpha hydroxy is found in anti-aging skin care products under the names glycolic or lactic acids. It is commonly used as an ingredient in facial cleansers, masks, creams and chemical peels.
Expert Insight
According to the American Academy of Dermatology, alpha hydroxy reverses damage to the skin caused by the sun.
Warning
People with sensitive skin may experience allergic reactions (such as rashes) to alpha hydroxy skin care products.
