The comparison between narrowband ultraviolet B (UV-B) light therapy and broadband UV-B showed clinical efficacy through the use of both treatments. However, “narrowband UV-B offers a significant therapeutic advantage over broadband UV-B in the treatment of psoriasis, with faster clearing and more complete disease resolution.” These results were determined from the study conducted by Coven, Burrack, Gilleaudeau, et al., where twenty-two patients suffering from moderate-to-severe plaque psoriasis were examined.
