ABSTRACT:
A mechanical element allows the tip of the handpiece of a dermatological treatment system to rotate to adjust for deviations in handpiece angle with respect to the surface of the treatment area. The tip may glide over the surface of the skin, the tip may include wheels or rotating cylinders on which the tip rolls across the skin, or the tip may be removed from the skin and placed in a new location in a stamping motion. The tip of the handpiece rotates around a single axis, or around two perpendicular axes, so that pressure on the tip moves the flat surface of the tip into proper orientation for planar contact with the skin. An element can be included in the handpiece to apply a restoring force on the tip so that the tip rests in its optimal position in the absence of external forces.
