For decades, dermatologists have used ultra-violet light therapy for the effective and safe treatment of many skin disorders, including psoriasis. The medical engineers and research teams at PhotoMedex in coordination with Rox Anderson, M.D. at Harvard Medical School and Wellman Center of PhotoMedicine in Boston, created the XTRAC to produce a monochromatic wavelength (308nm) of ultraviolet light known to positively impact the psoriasis action spectrum.
XTRAC has been cited in over 45 clinical studies and research programs with findings published in peer-reviewed medical journals around the world and endorsed by the National Psoriasis Foundation.
