Is ultraviolet ray effective in treating vitiligo?

Can ultraviolet rays treat vitiligo? How long can vitiligo be recovered with ultraviolet rays? The expert replied that it takes different time according to everyone's condition. When you use this method, you must go to a regular specialized hospital for medical treatment, and don't think that ultraviolet rays are the best treatment, and it is not a good thing after a long time. So what is the ultraviolet treatment of vitiligo? In theory, ultraviolet therapy can increase the photosensitive reaction of pigment cells and promote pigment cells to produce more melanin, which is a traditional treatment method. There are still books and periodicals. How long does it take for vitiligo to recover from ultraviolet rays? There is no fixed answer. Moreover, according to clinical trials, some patients will have other problems after using ultraviolet rays. Ultraviolet ray is an effective sterilization method, but it is also very dangerous. Many patients have obviously improved leukoplakia after a period of ultraviolet treatment, but some experts believe that ultraviolet treatment of vitiligo may stimulate the disease to deepen, and long-term use of this treatment may also lead to the risk of tumor. Therefore, how long the ultraviolet radiation of vitiligo needs to be determined according to the patient's condition. It is not that the longer the ultraviolet sterilization time, the better, or even harmful to people. Cause harm? Then why is this? In some patients, after ultraviolet irradiation, local skin redness and blistering reaction are the manifestations of serious damage to skin and subcutaneous tissue. With the extension of light time and intensity, the damage of pigment cells deepened and the function of producing melanin lost. The melanin around and in the center of leukoplakia gradually subsided, the area of leukoplakia expanded, the whiteness increased, and even the disease spread rapidly. Visible ultraviolet therapy should also be used with caution. The article said at the beginning that if you want to use this technology to treat vitiligo, you should go to a regular hospital and check the treatment at any time to ensure that problems or unreasonable treatment methods are found in time. The professional hospital technology is strong enough to make patients take fewer detours and spend less money. I sincerely wish all patients a speedy recovery.
