Vitiligo is a skin condition that is characterized by white patches on the skin. It destroys the cells responsible for creating the pigment of the human skin, thus leading to the formation of white patches, which can develop in any area of the body. Researchers believe that vitiligo is caused by an immune disorder, such as UC. In fact, over 20% of individuals with vitiligo also have UC. Treatment options for this condition generally include the use of topical corticosteroids.
