A new technology developed by Israeli dermatologists for treating psoriasis, vitiligo, atopic dermatitis and leukoderma has been cleared by the US Food and Drug Administration (FDA) to be marketed in the US. MultiClear, manufactured by CureLight Ltd., of Or Akiva, Israel, is a computer-controlled, targeted phototherapy system that uses both UVB and UVA rays. CureLight said the device allows "the exact matching of wavelengths and doses to optimally treat specific skin disorders." MultiClear will be featured at a forum at the American Academy of Dermatology's annual meeting, to be held Feb. 9 in Washington, D.C., and will be available in the US by March. . . .
