This is because of the fact that the skin contains a pigment called melanin. It gives color to the skin, hair, and iris of the eyes. There are three types of melanin: Eumelanin, pheomelanin, and neuromelanin each with its own job. Other people possess fewer melanocytes than normal, which also results in less overall pigment and lighter skin. we respect your privacy and take protecting it seriously. … Melanin is what gives the skin pigment (color). Melanin is the pigment that determines skin colour as well as hair and eye colour. Melanin production happens in the upper most layer of skin called epidermis.

Melanin protects skin from the sun's ultraviolet rays. Treatment can vary based on the extent of Melasma and the darkness of patches.

Our world is a wonderfully diverse and beautiful place, with millions of species of animals and plants, capped off by the most dominant species human beings. Similarly, the KIT ligand gene and Agouti signaling peptide gene control eumelanin production, and were positively selected in populations that moved out of Africa, to areas where less eumelanin (brown and black pigment) was needed. Treatments to sunspots include topical lotions and gels along with dermabrasion, microdermabrasion, and laser therapy for melanin removal.
