Kojic acid is an agent that is extracted from different types of fungi, especially the different strains of Aspergillus (a kind of fungus). It was first discovered in 1907 and was extracted from a strain of Aspergillus called Aspergillus oryzae grown on steamed rice.
Kojic acid brightens your skin by inhibiting melanin production. Melanin is the pigment that colors your skin, eyes, and hair. Over production 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.
