Vitiligo is a skin disease in which the skin loses its colour in patches due to depigmentation of body parts. Vitiligo can affect any body part which has pigment including skin, hair, inside mouth or in the eyes. Our body gets it colour from the pigment melanin and when the cells producing this die or stop functioning, Vitiligo develops. It is noncontagious and non-life threatening.
Signs and Symptoms of Vitiligo:
The only sign of Vitiligo is depigmented patches. The loss of colour depends on amount of pigment lost. The lesions may be chalky white or milky white or three colours may be seen in the same patch. They can occur anywhere on the body especially on pressure points.
Causes of Vitiligo
