Abstract
A device for treating the skin comprises a handpiece assembly having a distal end and a proximal end and a tip on the distal end of the handpiece assembly. The handpiece assembly includes a fluid delivery conduit, a waste conduit and/or an energy delivery conduit. Further, the tip is configured to contact the skin. The tip comprises a peripheral lip and a plurality of needles generally positioned within the peripheral lip. The tip also comprises at least one opening in fluid communication with a fluid delivery conduit, at least one opening in fluid communication with a waste conduit and/or an energy contact point in electrical communication with an energy contact point and energy conduit in the main body portion. The plurality of needles may be movable with respect to the peripheral lip through the use of a pneumatic or other force.
