Kojic acid powder is a chelation agent produced by

several species of fungi, especially Aspergillus oryzae, which has the Japanese common name koji. Kojic acid is a by-product in the fermentation process of malting rice, for use in the manufacturing of sake, the Japanese rice wine. It is a mild inhibitor of the formation of pigment in plant and animal tissues, and is used in food and cosmetics to preserve or change colors of substances.

Kojic acid attacks the root of the pigmentation source by inhibiting the production of melanin. More specifically, kojic acid counters the antioxidant properties of the enzyme tyrosinase, which reacts with an amino acid called tyrosine to produce melanin. By stopping the production of melanin, kojic acid can reverse excessive darkening of the skin.

Kojic acid powder brightens your skin by inhibiting melanin production. Melanin is the pigment that colors your skin, eyes, and hair. Overproduction of melanin often gives you dark spots and uneven skin tone. Your body produces melanin with the help of an amino acid called tyrosine. Kojic acid inhibits the function of tyrosine, which, in turn, inhibits melanin production.
