Naturally, you are beautiful, but the environmental pollution, use of sub-standard cosmetics, and the bright sunlight raises level of Melanin in your skin. As a result, blemishes appear on your face and your face complexion becomes unfair. According to Scientific Approach, skin color depends on MELANIN, (a natural pigment) that lies in inner layer of your skin. It works in such a way that it keeps the outer layer of your skin from harmful effects of ULTRA-VIOLET RADIATIONS; MELANIN is a combination of EUMELANIN & PHEUMELANIN. Skin complexion depends on the appropriate proportion of these two pigments.
