Vitiligo is a chronic disease that causes skin depigmentation. The disease promotes the development of unsightly white patches, and can severely alter ones appearance. The body's white blood cells attack the skin's pigment cells due to a genetic mutation. There is no cure for vitiligo, but there are treatments available to lessen the appearance. The disease doesn't affect one's overall health, but can be very a difficult thing to deal with psychologically and emotionally looking different from everyone else.
