Vitiligo is a skin condition in which the skin loses pigment, resulting in white patches. Cells within the skin known as melanocytes are responsible for skin pigmentation. These cells produce melanin which determines the color of the skin. In people with vitiligo, these cells die and stop functioning. Gradually this results in patches of skin that lose their pigment and become white. Vitiligo can affect people of all races and skin tones, but it is most disfiguring for people with darker complexions.
