Phototherapy and home phototherapy
Ultraviolet phototherapy has been used to treat vitiligo in recent years. Phototherapy is a type of physical therapy that has excellent therapeutic effects with minimal side effects. With the development of modern medicine, ultraviolet light therapy has become the most commonly used basic treatment method. Currently, the most mainstream therapy is irradiation with narrow-spectrum ultraviolet light. Ultraviolet phototherapy usually takes up to several months. For relapsed patients, early diagnosis and treatment once the disease is discovered will greatly control the development of the disease, shorten the course of the disease, and increase the chance of cure.
Generally speaking, the shorter the onset of vitiligo, the better the treatment effect. The area of vitiligo is smaller in the early stages of recurrence, and treatment at this time is more effective. If the disease is delayed and develops to a larger area, the treatment effect will become less effective. Moreover, the melanin in the white spots of older people is often completely destroyed, and treatment is difficult if only the non-functional and inactive melanocytes in the middle and lower parts of the hair follicles proliferate. If the disease progresses to the point where all hair turns white, treatment will be very difficult, and may even be Invalid.
Due to the portability of home ultraviolet phototherapy equipment, patients can receive treatment as soon as possible when recurrence occurs, so they can often achieve better treatment results. The treatment cycle for vitiligo may be longer than that of other skin diseases. Since home phototherapy can be completed at home, it greatly saves the time and energy investment of patients and their families. Phototherapy has no impact on the patient's normal work and rest, and it does not need to be administered simultaneously with other drugs, which greatly reduces the possibility of other side effects.
In a family environment, patients can personally feel the care of family members, which also helps the patient's psychological adjustment and promotes treatment effects.
