What is it and what causes it?
Vitiligo is a chronic disorder in which the skin slowly loses melanin (responsible for skin pigmentation) resulting in gradually enlarging, white irregular patches on the skin. The most common areas affected by vitiligo are above the eyes, neck, armpits, elbows, genitalia, hands and knees although other areas may also be affected. The exact cause of vitiligo is not known, however it is largely thought to be the result of an autoimmune response.
Treatment for vitiligo may involve;
- The prescription of topical corticosteroids and other medications for their anti-inflammatory and immunomodulating effects.
- Ultraviolet light therapy (UVB): Exposing the skin to Type B UV light suppresses the skin’s inflammatory response and is thought to aid in the re-pigmentation of the skin.
