Kojic Acid

501-30-4

Kojic acid is an alpha-hydroxy acid (AHA), which is a chemical exfoliator. “It’s derived from the fermentation of certain foods, including Japanese sake, soy sauce, and rice wine,” explains Deanne Mraz Robinson, MD, FAAD, a board-certified dermatologist and CMO of Ideal Image. “It is an active ingredient most often found in serums, lotions, chemical peels, and exfoliators.”Kojic acid is best known for its ability to lighten hyperpigmentation as well as evening out and brightening skin tone. Dr. Robinson explains that it works in two ways: First, it chemically sloughs away hyperpigmented skin cells that already exist on the complexion, then it works to prevent hyperpigmentation in the first place, by suppressing the production of tyrosine, which is an enzyme that helps our bodies produce melanin. Dr. Robinson adds that kojic acid can also help manage acne because it has anti-bacterial properties.
