Kojic acid（Cat No.:R047524）is a natural compound derived from fungi, widely used in skincare for its skin-brightening and antioxidant properties. It works by inhibiting tyrosinase, an enzyme responsible for melanin production, effectively reducing dark spots, hyperpigmentation, and uneven skin tone. Kojic acid is a popular ingredient in creams, serums, and lotions aimed at achieving a more radiant complexion. Beyond its cosmetic uses, it also has mild antibacterial and antifungal effects, adding to its versatility in skincare formulations. Gentle yet effective, kojic acid is favored for promoting a brighter, more even skin appearance.
