1. Significantly reduces the production of melanin by inhibiting tyrosinase activity. This results in a reduction of Dopaquinone, an intermediate of melanin synthesis. Additionally it converts existing Dopaquinone to L-Dopa
2. Can significantly lighten existing black melanin by a reduction reaction
3. Can dramatically reduce the free radicals that result from UV irradiation of the skin, and significantly reduce cell damage
4. Promotes collagen synthesis of skin fibroblasts. Collagen is a protein that plays an important role in the structure and firmness of skin.
