UVB Phototherapy
Type:Uv phototherapy Time:2015-12-19 11:58:55UVB phototherapy refers to irradiation with short wave ultraviolet radiation. To treat the whole body, the patient, undressed, stands in a specially designed cabinet containing fluorescent light tubes.
Traditionally, broadband UVB has been used, but increasingly, narrowband UVB phototherapy (311nm) is provided.
Increasing doses of UVB are given each exposure (three to five times weekly), aiming to turn the skin slightly pink. Sometimes uncomfortable sunburnwill occur, at its worst about 8 hours after treatment. This fades over the next few days and should be treated with frequent and liberal emollients.
The effect of UVB is similar to the sun. Excessive exposure contributes to aging skin and to the risk of skin cancer.
