The amount and distribution of melanin, a coloured polymer made by melanocytes, play a major role in determining skin colour. Although heavy metals or drug metabolites can alter skin colour, hyperpigmentation nearly invariably results from either excessive melanin production or aberrant pigment distribution.Melanin content is mainly produced due to genetic factors, but at same time environmental factors can influence along with diet of the indidvidual.
