This is the device that uses targeted ultraviolet-B light to help minimize the development of psoriasis, vitiligo, and eczema. The UV-B light slows the abnormal growth of skin cells and can help create re-pigmentation of discolored skin. The wand emits 312 nm light and has an LCD display with a built-in timer that ensures accuracy of treatment time. Users simply apply the wand to the targeted area for 40-second treatments for two to three times a week (treatment frequency and time for result vary on skin condition). For use on all skin tones. AC plug. 16" L x 7 1/2" W x 4" D. (2 1/2 lbs.)
