Vitiligo is a disease that causes the loss of skin color in blotches. The extent and rate of color loss from vitiligo is unpredictable. It can affect the skin on any part of your body. It may also affect hair, the inside of the mouth and even the eyes.
Normally, the color of hair, skin and eyes is determined by melanin. Vitiligo occurs when the cells that produce melanin die or stop functioning.
Vitiligo affects people of all skin types, but it may be more noticeable in people with darker skin.
Many treatments are available to help restore skin color or even out skin tone. Results vary and are unpredictable. Some treatments have serious side effects.
