What is vitiligo definetion?

Vitiligo is a skin condition characterized by the loss of pigment, resulting in white patches on the skin. This occurs when melanocytes, the cells responsible for producing skin pigment, are destroyed or stop functioning. The exact cause of vitiligo is not fully understood, but it is believed to involve autoimmune factors, genetic predisposition, and environmental triggers. The condition can affect people of all skin types and may also impact hair and mucous membranes.
