Vitiligo phototherapy harm?

First, it is easy to damage the eyes. Secondly, the time of phototherapy and the distance of irradiation are also very important. If you do not have a good grasp of the amount of erythema on your skin, it is easy to damage the skin if the time is too long or the distance of irradiation is too close

Second: there will be erythema reaction, which is mainly due to the excessive dose of ultraviolet radiation. If the erythema reaction is serious, the irradiation should be suspended. After the erythema subsided, the radiation dose was reduced appropriately.

Third: the long-term radiation reaction can promote skin aging, clinical manifestations are punctate pigmentation and loss, dry skin, atrophy and keratosis transition

matters needing attention

1. For patients with psoriasis, before ultraviolet phototherapy, take a bath or shower to minimize the scale of the epidermis. 2. During irradiation, you must wear ultraviolet goggles. Due to the blackening effect of phototherapy, normal skin can be properly covered with clothing, or use anti light agent. Male patients should avoid irradiation on the genital parts as far as possible
