exposed areas.Vitiligo is a pigmentation disorder in which melanocytes (the cells that make pigment) in the skin are destroyed. As a result, white patches appear on the skin in different parts of the body.
Exactly what it is can only be determined after examination.For that consultation of a dermatologist will be the best. Hope it helps.Take care and pls do keep me posted on how you are doing or in case you have any additional doubts.Kind regards.
