The condition appears medically harmless, other than the problem that the affected skin areas have no protection against sunlight - they burn but never tan. However, if the skin is naturally dark, the visual effect of the white patches can be quite disfiguring. (If the affected person is of pale-skinned ancestry, the patches can be at least be rendered invisible by the expedient of avoiding sunlight and the tanning of unaffected skin.)
In some cultures there is a stigma attached to having Vitiligo. Those affected with the disorder are sometimes thought to be evil or diseased and are sometimes shunned by others in the community.
It has been claimed that the singer Michael Jackson has his skin bleached to mask the effects of vitiligo.
