A handpiece is disclosed comprising a handpiece body for transmitting intense pulsed light through a distal end of said body to a skin target and a light delivery means for delivering said light from a light source to said distal end and further a clear transmitting element mounted within said handpiece, said transmitting element being transparent to said light. The handpiece further comprises an evacuation chamber is connected to, or integral with, said body and is disposed distally to said transmitting element, air or condensed vapors being evacuated from said evacuation chamber upon application of a sufficient vacuum therein. The handpiece further comprises means for positioning said transmitting element to be substantially parallel to said skin target and for positioning a wall of said evacuation chamber to be substantially in contact with said skin target as well as means for directing the light which is transmitted through said transmitting element and said distal end to said skin target via said evacuation chamber. In the handpiece, the energy density of said light ranges from 1 to 70 J/cm2, the wavelength of said light ranges from 400 to 1800 nm, and the pulse duration ranges from 10 nanoseconds to 900 msec. <IMAGE> |
