Skin color is due primarily to the presence of a pigment called melanin , which is controlled by at least 6 genes. Both light and dark complexioned people have melanin. However, two forms are produced--pheomelanin , which is red to yellow in color, and eumelanin , which is dark brown to black. People with light complexioned skin mostly produce pheomelanin, while those with dark colored skin mostly produce eumelanin.
An uneven skin tone is most commonly caused by UV rays from the sun, however, age, hormonal changes, chemicals, and pollutants can also cause this condition. Additionally, the body itself too can cause uneven skin tones and blotchy skin by attacking the cells that produce melanin.
