Kojic Acid was first discovered in Japan back in 1907. It was extracted from a strain of fungus known as Aspergillus oryzae which grows on steamed rice. Scientists found out that the extraction inhibited overproduction of melanin. Melanin is the pigment responsible for your eye, hair and skin color. Overproduction of melanin is what causes the darkness in skin. And the amino acid called tyrosine is what encourages the presence of melanin. Kojic acid actually stops the tyrosine from functioning. Thus, Kojic Acid Lightens Your Skin and Reduces Dark Spots.
