what are the two types of melanin
Melanins have the power to absorb ultraviolet rays, and thus they protect the skin from attack by solar radiation. This is translated into a more or less intense tanning of the skin. A palette of colour. There are two types of melanin: pheomelanin which is yellow coloured, and eumelanin which is black. It is the proportion and size of these pigments, without forgetting the carotenoids and the blood micro-circulation which gives the wide range of skin colour.
