Melanin
Melnain is the skin pigment that is found in almost all the members of animal kingdom, which as a result of absorption of selective color (wavelength), determines the complexion of skin, hairs and eyes. It is ubiquitous in nature and is formed in intracytoplamatic unique organelles known as melanosomes.Melanin is found in multiplicity locality in the human body, from the eye and ear to the brain and the skin. Every location contains different variety and nomenclatures of melanin. The melanin in brain is neuromelanin where as melanin present in the skin are eumelanin and pheomelanin. Only the function of skin melanin i.e. eumelanin and pheomelanin are understood by the researches yet, however others are still a mystery. The ratio of eumelanin and pheomelanin present in the skin determines the complexion of skin.
What is Eumelanin
Eumelanin is a black or brown pigment which warrants the melanin to be termed as photoprotectant. It enables the melanin to provide protection to skin against radiation of sun. The determinant function of eumelanin is to absorb the UV radiations. The greater the number of eumelanin present, the darker would be the skin tone... Read MoreWhat is pheomelanin
Pheomelanin is the redish pigment that acts as photo-sensitizer making the skin sensitive to light. It is a weak absorber of UV radiations and it increases the sun sensitivity and skin ageing factor... Read MoreMelanin and Vitiligo
Numerous studies of vitiligo cure have suspected the lack of melanin as a major factor for the occurrence of white patches. However, the real cause of vitiligo, i.e. the real cause for deficiency of melanin is still undiscovered.The treatments for vitiligo that has been discovered are on the basis of theories suggested through the researches that were accomplished to find out vitiligo cure and therefore works to enable the melanocytes to re-function properly and produce required amount of melanin.
