For more localized areas of involvement, the same wavelength of light in narrow-band UVB phototherapy can be applied with a laser hand piece. There are several advantages to this. The Pharos Laser uses a carefully focused beam of high-dose therapy to deliver the light energy. Because only diseased skin is treated, the risk of burning normal surrounding skin is reduced, and treatment energies can be much higher. This allows more aggressive treatment resulting in faster results with fewer treatments.
