Vitiligo is a common skin disease in Indian, Middle East, as well as South Africa. It has a great influence to people’s life, and social work, and life quality. It also threatens people’s health a lot.
Vitiligo is a skin condition characterized by white patches. These skin patches are missing the skin pigment melanin; in most cases, the condition is triggered by sunburn. Normally, excessive sun exposure first causes skin reddening, followed by peeling of the outer skin layers, and formation of darker skin in the exposed area ("tanned" skin). However, in some cases, a reaction occurs in which the melanin production is blocked and the skin loses its color. The patches of white are usually at the site of the burn, but it is also possible for additional patches to begin appearing elsewhere. Genetic factors are believed to contribute to susceptibility to experiencing vitiligo, and the condition might be triggered by conditions other than sunburn, such as viral infections and physical trauma to the skin.
