In order to help patients who are using or planning to use home phototherapy to treat 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't change the dose of light without authorisation

　　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 should be appropriate; too much or too little will affect the efficacy of the treatment. Although three times a week than two times a week to see the effect of fast, but not too often, the interval must be > 24 hours, otherwise it is easy to occur adverse reactions; can not be three days fish two days, more to avoid irregular treatment behaviour, 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.

　　Recommendation 3: Can not arbitrarily expand, reduce or change the part of the body that is illuminated

　　In the course of treatment, if there are new lesions in other parts of the body, the current dose of light can not be used to directly illuminate the light, and should be given a different dose depending on the situation. Each time you shine the light, you can't shine here and there, you must set the time to shine the next part of the body after one part of the body has been illuminated.

　　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. In the judgement of continuous light therapy is ineffective, depending on the type of disease and individual circumstances, at least need to complete a certain number of times or even longer light therapy, and confirmed by the doctor; such as no response, and then stop light therapy.

　　Suggestion 5: Do not rely on light therapy alone

　　Home phototherapy is mainly used for the treatment of vitiligo, psoriasis, etc. 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 programme, etc., can often achieve 1 +1 > 2 effect, and can make some of the original was considered stubborn, difficult to treat the situation has become simple, easy to cure.
