Use

Malic acid is the third smallest alpha hydroxy acid in terms of molecular size. Although it is used in numerous cosmetic products, particularly those indicating a “fruit acid” content and generally designed for anti-aging, unlike glycolic and lactic acids, its skin benefits have not been extensively studied.
