Exposure to sunlight after phototherapy is prohibited. Dermatology treatment: Questions Answers: How to determine the irradiation time of each increment? 1. If mild erythema appears in the previous irradiation and has subsided during the next treatment, it should be increased by 10 seconds based on the previous-time irradiation time. 2. If there is obvious redness in the previous irradiation and it has not subsided during the next irradiation, the original irradiation time should be maintained. 3. The maximum irradiation time for single irradiation is no more than 5 minutes for the face and torso; no more than 7 minutes for the limbs of the hands and feet. (Even if erythema does not appear, it does not increase the time) When does it become effective? 1. Generally, it takes about 20 times of irradiation to be effective. 2. If the irradiation is more than 40 times and there is still no obvious effect, the irradiation should be stopped. When should the irradiation be stopped? 1. With the extension of the irradiation time, if the skin becomes redder, or even blisters, redness, and swelling, the irradiation should be stopped, the irradiation should be started after a few days of rest, and the original irradiation time will be reduced by about 20%. 2. Generally, after three or three months of irradiation, you can suspend the irradiation to two weeks; the re-irradiation start time is about 70% of the suspension time.
