This buzzy ingredient will turn out to be your new lifeline for treating hyperpigmentation
“Kojic acid is made up of several different mushrooms,” says Jeannette Graf, Registered Dermatologist and Clinical Assistant Professor of Dermatology at the Mount Sinai School of Medicine. “It’s a by-product of certain types of mushrooms and fermented foods like rice wine, kimchi, and Japanese sake. Kojic acid inhibits tyrosinase, the melanin-forming enzyme. ”
In beauty products, kojic acid acts as a lightening agent. “Because kojic acid inhibits tyrosinase, it can be used to lighten unwanted hyperpigmentation,” says Karen Chinonso Kagha, MD, a certified dermatologist and Harvard-trained cosmetics and laser specialist.
