Phototherapy Treatment for PsoriasisOne of the treatment for psoriasis is Ultra Violet B (UVB) phototherapy using a contraption similar to sun tanning bed involving exposure to UVB radiation done over three visits each week for between eight to 10 weeks. This UVB phototherapy is usually done at a hospital as most dermatologists (skin doctors) believe that home phototherapy is inferior and that it carries more risks. This entails visits of 24 to 30 visits to the hospital. This means that only those fortunate to stay near hospitals can avail themselves to UVB Phototherapy.
Home phototherapy treatment for psoriaisiAccording to Dr. Mayke Koek of Utrecht University Medical Center who led a study of psoriasis patients from 14 hospital dermatology departments randomly assigned to either home-based or hospital-based UVB phototherapy, home-based phototherapy was found to be equivalent to hospital-based phototherapy both in terms of efficacy and safety. Not only that, the study found that those receiving home-based phototherapy were significantly more satisfied.
