Abstract: A dermatological handpiece by which a laser beam is directed to the surface of a selected skin area for purposes of a cosmetic treatment and the skin area is subjected to the action of the laser beam. A method is also disclosed for the cosmetic treatment of skin surfaces during the operation of this handpiece. A handpiece of the type described above is outfitted with a device for moderating the temperature of the skin surfaces on which the laser beam acted immediately beforehand and/or is to be subjected to the action of the laser beam immediately following the temperature moderation. The handpiece is further provided with elements for influencing the laser beam cross section with respect to shape, dimensioning and intensity distribution.

Abstract: A medical handpiece is disclosed which is connected with a laser radiation source via a beam guidance device and by which a laser beam is directed to a treatment area. The handpiece is freely movable to the laser beam source. At least one optical element with a surface which is structured in the micrometer range and which is accordingly micro-optically active is provided inside the handpiece following an exit face of the beam guidance device.
