Kojic Acid is a key ingredient in numerous lightening creams, soaps, and serums. Kojic acid lightens skin by inhibiting melanin production. Melanin is the pigment that gives color to your skin, eyes, and hair. Overproduction of melanin of the skin causes dark spots and a blotchy skin tone. The 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.
