Kojic acid is a natural substance that is derived from fungi, such as Aspergillus oryzae and Penicillium species. It is commonly used in skin care products as a skin-lightening agent because it can inhibit the production of melanin, the pigment that gives skin its color. Kojic acid works by blocking the enzyme tyrosinase, which is responsible for the production of melanin. This helps to lighten the skin and reduce the appearance of dark spots, age spots, and other types of hyperpigmentation.
