Description Kojic cream is sometimes used in health and beauty products to lighten the skin. It may be used to treat skin conditions, such as sun damage, scars, and age spots. The science behind how kojic acid works as a lightening agent involves its effect on melanin production. Melanin is a naturally occurring pigment in the body that gives the eyes, hair, and skin their colour. An amino acid called tyrosine is needed to support the production of melanin.
