Kojic acid soap is a skin care product used to brighten dark spots on the skin, known as hyperpigmentation. 1 Kojic acid is made from fungi or fermented rice wine. When used on the skin, kojic acid helps prevent your skin from forming tyrosinase, which is an enzyme that helps create skin pigment (melanin).
