how to use uvb light for vitiligo ?
1, the first time to use UVB, first with a low dose (can be controlled by time), can start from 20 seconds, once a day.For three consecutive days, local lesion did not change, can be added to the 30 seconds, and so on, to a certain dose irradiation after 3 days, areas of red, the dose can be identified as the lowest dose, and according to the dose every sunshine again, keep the local lesion slightly pink, when the irradiation dose after a period of time, local skin pink color to reduce, can add dose,Keep local skin lesions pink.
2. The tolerance of different parts of the skin to UVB is different, so the therapeutic dose of each part of the skin is also different, and the lowest dose of each part of the skin should be explored and fumed out, and recorded.
3, in the UVB irradiation must protect the eyes, because the fundus also contains pigment cells, ultraviolet radiation will cause vision loss, generally wear glasses.
4，It is recommended not to irradiate the general special parts, such as vulva, women, etc.
5. Because UVB irradiation can cause the function of normal melanocytes to be active, produce more melanin particles, and make the skin black, it is recommended that you protect the surrounding skin during UVB irradiation. You can cut a hole in your clothes or cloth (the edge of the hole is 0.5cm larger than the skin lesions).Change into clothes with holes and cover them up every time you shine.In order to avoid causing the normal skin around the injury.
