Genetically, everyone is born with the same amount of "Melanocytes", or the cells that produce melanin. It is your global background that dictates how much melanin you eventually will have in the skin.
Example: Typically those whose background stems from ancestors who have lived closer to and south of the Equator have more melanin in their skin. Where those whose background is from ancestors that have lived in the Northern Hemispheres typically do not tan and have less melanin in their skin. Conditions such as Albinism and Vitiliago also may also compromise the amount of melanocytes in the body.
Melanin by definition is two fold...one is olor coloring and the second is protection from UV.
