Vitiligo, if left untreated for a sustained period of time, may end up being all white. Vitiligo is a chronic, long-term, incurable acquired hypopigmentation disorder that can be categorized as limited, disseminated, or generalized. Among them, limited and scattered vitiligo can only lead to localized areas of skin whitening after rapid expansion, and will not lead to the whole body whitening. However, generalized vitiligo, if left untreated or improperly treated, can lead to localized fusion of white spots and eventually spread to the whole body. Vitiligo patients can use fluticasone propionate cream, halometasone cream, tacalcitol ointment and other medications according to the doctor’s instructions in the early stage of the disease. If the use of medications is ineffective, epidermal grafting can be carried out in the stabilization period, in which the epidermis of the normal skin is taken off and covered in the area of the white patches. Phototherapy can also be chosen, using ultraviolet light or laser irradiation of white spots, prompting the white spots to change color. It is recommended that once the diagnosis of vitiligo is confirmed, you should seek medical treatment in a timely manner and use the medication as prescribed by the doctor to avoid serious consequences.
