Vitiligo is a common skin condition in which patches of the skin lose pigmentation and appear white. These patches develop when melanin is not produced properly, and tend to spread over time as the condition progresses. Some patients may also experience premature whitening of the hair and a loss of color inside the mouth. Although not harmful, patients with vitiligo are often bothered by their appearance and may seek treatment to correct their skin tone.

Treatment for vitiligo depends on the severity of the condition, and may include oral or topical medications, UVB therapy, depigmentation or skin grafts. While there is no cure for this condition, treatment is often effective in improving the appearance of the skin.
