a tip positioned along the distal end of the handpiece assembly;
the tip comprising a peripheral lip and an interior lip, wherein a first region is defined between the peripheral lip and the interior lip, wherein the interior lip defines a second region, the second region being separated from the first region by the interior lip;
wherein the interior lip completely circumscribes the second region and isolates the second region from the first region when the interior lip contacts skin tissue;
wherein both the peripheral lip and the interior lip are configured to contact a skin surface when the tip is positioned along the skin surface of a subject;
at least one vacuum port located along the first region, the at least one vacuum port being configured to be placed in fluid communication with a vacuum source, wherein suction is created within the first region when the peripheral lip and the interior lip contact the skin surface and the vacuum source is activated;
at least one fluid delivery passage, wherein a fluid is configured to be delivered to the first region via the at least one fluid delivery passage; and
an air delivery passage for delivering air to the second region, wherein air delivery to the second region facilitates transfer of fluid at least partially into the skin.
11. The device of claim 10 , wherein air is delivered in a pulsed manner to the second region.
12. The device of claim 10 , further comprising at least one abrasive structure positioned within or along the first region, the at least one abrasive structure being configured to at least partially abrade skin tissue when the tip is moved relative to the skin surface.
