You'll often lose pigment quickly on several areas of your skin. After the white patches appear, they may stay the same for a while, but later on, they might get bigger. You may have cycles of pigment loss and stability. Vitiligo commonly affects body folds (such as armpits), places that have been injured in the past, and areas exposed to sun, around moles, or around body openings. It can also affect eyelids and hair. It's rare for pigment to return once the white patches have developed.
