Excimer Laser

Excimer laser in which “excimer” is a terminological reference of “excited dimer”, composed of a noble gas and halide which repel each other, has turned into a prevalent mode of action in confronting numerous skin disorders 1. Of these ultraviolet B rays which comprise beams of varied wavelengths, the 308nm xenon-chloride is the most practical in dermatology 1. The advantages of monochromatic excimer laser over phototherapies of other kinds have been depicted as lower UV dose exposure, shorter course of therapy and for the most part, the possibility of being directed at distinct sites of skin rather than compromising the adjacent normal skin 2, 3, 4. The aim of this overview of excimer laser was to summarize all reported uses of this kind of laser in different dermatologic diseases.
