Research shows vitamins and other antioxidants from certain fruits and vegetables reduce melanin production and its transport to the top layers of the skin. For example, lemons, a popular natural skin lightener, contain the powerful antioxidant vitamin C (ascorbic acid), which has several functions in skin. Vitamin C lightens skin by inhibiting tyrosinase, the first enzyme on the pathway to melanin production. Other plant life also has various chemicals that interfere with melanin production or transport.
