Vitiligo: Overview


Our skin gets its color from pigments. They are colored pigments. People with dark skin have more of these pigments and those with lighter skin have less of them. This pigment is known as melanin. The main function of melanin is to protect the body from sunrays. That is why, we get tanned when we expose ourselves to sun. Tanning means more production of melanin. Cells known as melanocytes in the skin produce melanin.

If for any reason, the skin begins losing melanin from a patch on the body, light skin develops on that place. This is called Vitiligo. There is no specific cause known for vitiligo except for the thought that the body destroys the melanin itself. That is why this is called an autoimmune disease (a disease where the body attacks itself). Vitiligo can develop on the whole body, or it can stop after creating few patches. Anybody can get it on any part of the body. There is no perfect cure for it. It can be treated in various ways, but no satisfactory treatment is available. There is no prevention for vitiligo and no cure. Vitiligo also exposes skin to sun rays and that is dangerous. Let us find out more about it.
