psoriasis phototherapy, how to shine?

 

In most cases, phototherapy is used alone, which is safer, like sun exposure, with fewer side effects. If you want to combine other treatments, it is recommended to use a combination of topical medications. Usually applied externally at the interval of phototherapy, such as 135 or 246 per week, then external emollients, calcipotriol ointment or glucocorticoids can improve the efficacy when not in the light or after the light. . Combined oral medication is not the first choice. Only when the effect of phototherapy is not strong enough, the oral administration of retinoic acid or methotrexate is combined to increase the efficacy. There are also doctors using Tripterygium wilfordii. This is mainly based on the doctor's experience and is generally not recommended. Use cyclosporine.

 

¡ñ Phototherapy can be either full body or partial

 

Phototherapy is divided into whole body phototherapy and local phototherapy. Whole body phototherapy is suitable for large-scale generalized psoriasis, which requires full-cavity exposure; local phototherapy is suitable for single or several limited skin lesions, refractory skin lesions, small machines that require local irradiation, half-length machines, and even Targeted irradiation machine. For special parts of psoriasis, such as scalp psoriasis, there are currently phototherapy combs. Therefore, according to the condition, choose different treatment instruments, so that the phototherapy can be used for whole body irradiation or partial irradiation to maximize the effect.

 

¡ñ Phototherapy usually takes place once every other day

 

According to the condition, the number of phototherapy we recommend is three times a week, once every other day, and for 2 to 3 months. So 36 times in 3 months, this is the recommended course of treatment. Each irradiation time depends on the intensity of the illumination, and the intensity of the illumination is not constant. As the number of illuminations increases, the amount of light is gradually increased, ranging from a few tens of seconds to a few minutes.

 

Because phototherapy is a long, gradual process, it does not see the effect after one exposure. Usually it takes about 2 weeks to work, and the skin will be obviously improved in 1~2 months, and it will have satisfactory results in 2~3 months. When it works, the initial red color of the skin lesions will become lighter, lighter, the scales will decrease, the skin will become thinner, and the color of the normal skin will gradually return. Light can cause hyperpigmentation (tanning), but after stopping phototherapy, pigmentation will gradually subside.
