Vitiligo is a common acquired limited or generalized skin pigmentation loss disease, early symptoms of localized lumpy, less number of white patches and so on. Vitiligo early symptoms are mostly of varying sizes, irregularly shaped patches, nearly round, oval, linear milky white or porcelain white depigmented patches with clear borders. The number of white skin patches appearing is small, about 1-2 pieces. Most of them appear on the skin that is often exposed to the sun. The skin has no itching or the itching is very mild, which can be limited to a certain part of the body or distributed in a nerve segment, and the white spots seldom disappear on their own. There may also be normal skin remaining in the white patches, which is mistaken for hyperpigmentation, such as occurring on the face, which is often mistaken for melasma. This is also an early symptom of vitiligo. When the above symptoms occur, it is recommended to consult a doctor in time, follow the doctor’s instructions for further examination, clarify the cause with the doctor’s help, and carry out targeted treatment or therapy.
