Skin Whitening Effect

Dullness, darkness, and spots of the skin are caused by melanin. In vivo, melanin forms dopa quinone from tyrosine by the action of tyrosinase. Subsequent progression of oxidation results in the formation of melanin. Litchi Seed Extract inhibits tyrosinase activity and appears to be applicable to foods and cosmetics for whitening. This tyrosinase inhibitory activity of Litchi Seed Extract was comparable to that of Vitamin C.
