개요
DL-Mandelic acid is a chemical compound belonging to the family of alpha hydroxy acids (AHAs). It is a racemic mixture containing equal amounts of the D and L enantiomers of Mandelic acid. It is commonly used in skincare products for its exfoliating and antibacterial properties. DL-Mandelic Acid is useful in suppressing pigmentation, treating inflammatory non-cystic acne, and rejuvenating photoaged skin. Moreover, it has proven useful in preparing the skin for laser peeling and helping the skin heal after laser surgery. This product appears as a white crystal substance.
