Vitiligo is a condition that causes depigmentation of parts of the skin. It occurs when melanocytes, the cells responsible for skin pigmentation, die or are unable to function. The cause of vitiligo is unknown, but research suggests that it may arise from autoimmune, genetic, oxidative stress, neural, or viral causes.The incidence worldwide is less than 1%. There are two main types of vitiligo: idiopathic and chemical. Most vitiligo is idiopathic, however in cases where it is triggered by skin bleaching or other substances, it is said to be chemical.
