Why did Michael Jackson's skin color turn white?

Michael Jackson's White Skin

Michael Jackson's skin was white because he had a rare skin condition called vitiligo.

Vitiligo is an inherited genetic disorder. It is a condition in which you lose melanocytes (cells that give color to the skin). This results in smooth, white-milky patches in the midst of normally pigmented skin. In the case of African-Americans, this discoloration is very prominent, although any age, sex and race can suffer from it.
