What is UVB – Select™ and how does it compare with other UVB treatments?
• UVB – Select™, the rated output of Levia’s proprietary light engine, is in the 300-320nm spectral band. Studies2, 3 have shown that this is the most therapeutically useful light in the treatment of psoriasis and is similar in effectiveness to Narrowband UVB (311-315nm). The elimination of the 290-300nm component of Broadband (290-320) UVB reduces the rays which primarily cause Erythema (redness of the skin). UVB-Select, therefore, allows delivery of stronger doses (multiple MEDs) to psoriatic plaques while minimizing the effect on surrounding uninvolved skin. 2.
