Vitiligo is a skin condition that causes the loss of pigmentation in patches on the skin. These patches can appear anywhere on the body and can be different sizes and shapes. The exact cause of vitiligo is not well understood, but it is believed to be an autoimmune disorder in which the body's immune system attacks and destroys the cells that produce pigment in the skin. Symptoms of vitiligo include the appearance of white patches on the skin, loss of color in the hair on the scalp, eyelashes, and eyebrows, and loss of color in the retina of the eye. The condition can affect people of all ages, but it is more commonly diagnosed in people under the age of 20. There is no known cure for vitiligo, but there are several treatment options available to help manage the condition. These include topical creams and ointments, light therapy, and skin grafts. Topical corticosteroids are often used to help reduce inflammation and re-pigment the affected skin. Light therapy, such as narrowband UVB therapy, can also be used to help re-pigment the affected skin.
