In order to help patients who are using or ready to use home phototherapy for psoriasis, vitiligo and other chronic skin diseases, we said in the last issue of the 5 "must" to do a good job of home phototherapy, this issue to remind you to pay attention to the 5 "can not", for reference.

　　Suggestion one: can not change the dose of light without authorization

　　Lighting dose is related to the efficacy and safety, self-adjustment of the dose is easy to make the efficacy worse, the dose is too low to play a role in the efficacy of the dose is too large to trigger a sunburn reaction and affect the continuation of the treatment. It is necessary to accurately grasp the starting dose, incremental dose and other indicators. Because of the phototolerance phenomenon of UV phototherapy, the dose of each treatment should be increased until the maximum dose of a single session. The erythematous response to light is the only parameter used to determine individual dose adjustments. The occurrence and extent of erythema after the last treatment should be clarified before each exposure. A mild erythematous reaction at the lesion is usually considered to be an indication of an appropriate dose.

　　Recommendation 2: The frequency of phototherapy should not be changed arbitrarily

　　The frequency of light exposure should be appropriate; too much or too little will affect the efficacy of the treatment. Although 3 times a week than 2 times a week to see the effect faster, but not too often, the interval must be > 24 hours, otherwise it is prone to adverse reactions; also can not be three days fish two days sun net, but also to avoid irregular treatment behavior, can not be because of the pursuit of early results, or due to lack of light leakage and increase the frequency of phototherapy, such as daily continuous light, or the same part of the day many times light.

　　Recommendation 3: Can not arbitrarily expand, reduce or change the body light parts

　　In the course of treatment, if there are new lesions in other parts of the body, the current dose of light can not be directly illuminated, and should be given a different dose depending on the situation. Each time you shine the light, you can not shine this and that, you must shine a good part of the body, and then set the time to shine the next part of the body.

　　Recommendation 4: Do not give up treatment easily

　　The effect of phototherapy is by no means immediate, many people in the treatment of 1 ~ 2 weeks, do not see the effect, give up the treatment, it is too bad to give up; phototherapy efficacy and the number of treatments related to the need to achieve a certain cumulative dose, that is, the number of times of illumination, and therefore have patience, to adhere to the treatment. Before determining the ineffectiveness of continuous phototherapy, depending on the type of disease and individual circumstances, at least need to complete a certain number of times or even longer phototherapy, and confirmed by the doctor; such as completely unresponsive, and then stop phototherapy.

　　Suggestion 5: Do not rely solely on light therapy

　　Home phototherapy is mainly used for the treatment of vitiligo, psoriasis, these chronic skin diseases need comprehensive treatment, phototherapy is only one of the treatment measures. Therefore, should actively cooperate with the water bath, external drugs, systematic medication and other integrated treatment, and pay attention to lifestyle and emotional adjustment. Phototherapy combined with other methods of combined treatment program, etc., often can achieve 1 +1 > 2 effect, and can make some of the original is considered stubborn, difficult to treat the situation becomes simple, easy to cure.
