uvb phototherapy instrument uses narrow spectrum UVB technology, its wavelength is 311nm, clinical trials have proved that the wavelength of 311nm in the narrow spectrum of ULTRAVIOLET radiation in the treatment of vitiligo and psoriasis and other skin diseases have significant effects, belongs to the pure physical therapy. Ultraviolet phototherapy instrument can emit 311nm uVB wavelength, the wavelength of UV can be mostly absorbed by the epidermal tissue, so the skin and other tissues have significant biological effects. Ultraviolet (uv) has good drying, sterilization, anti-inflammatory effects, the superficial within the organization directly kill bacteria or viruses, accelerate the blood circulation, analgesia, promote epithelial regeneration effect, so the ultraviolet irradiation treatment can directly kill Herpes virus to prevent secondary bacterial infection, promote the blister absorption, analgesic, accelerate skin repair and healing, Thus play a good therapeutic role. Research also found that uv phototherapy instrument irradiation can significantly inhibit the activity of epidermal langerhans cells and other antigen presenting cells, can reduce inflammatory reaction, improve local blood circulation, promote rash healing and pain relief, and less adverse reactions, simple treatment.
