Vitiligo is a long term skin condition characterized by patches of the skin losing their pigment. The patches of skin affected become white and usually have sharp margins. The hair from the skin may also become white. Inside the mouth and nose may also be involved.
Vitiligo may be an autoimmune disease. These diseases happen when your immune system mistakenly attacks some part of your own body. In vitiligo, the immune system may destroy the melanocytes in the skin. It can start at any age, vitiligo often first appears between the ages of 20 and 30. The white patches may begin on your face above your eyes or on your neck, armpits, elbows, genitalia, hands or knees. They’re often symmetrical and can spread over your entire body.
