1. A device for treating skin tissue, the device comprising:
- a handpiece assembly comprising a distal end;
a tip positioned along the distal end of the handpiece assembly;
the tip comprising a peripheral lip and an interior lip, wherein an annular region is defined between the peripheral lip and the interior lip, wherein the interior lip defines an interior region, the interior region being separated and isolated from the annular region by the interior lip;
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, wherein when the peripheral lip and the interior lip contact skin during use, the annular region is hydraulically isolated from the interior region;
at least one vacuum port located along the annular 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 annular region when the peripheral lip and the interior lip contact the skin surface and the vacuum source is activated;
at least one abrasive structure positioned within or along the annular 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;
at least one fluid delivery passage, wherein a fluid is configured to be delivered to the annular region via the at least one fluid delivery passage; and
an air delivery passage for delivering air to the interior region, wherein air is delivered in a pulsed manner to the interior region, wherein air delivery to the interior region facilitates transfer of fluid at least partially into the skin.

18. A device for treating skin tissue, the device comprising:
- a handpiece assembly comprising a distal end;
a first region and a second region defined along the distal end of the handpiece assembly, wherein the second region is separated from the first region by an interior lip or ridge; wherein the interior lip or ridge completely circumscribes the second region and separates the second region from the first region when the interior lip or ridge contacts skin tissue; 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 distal end of the handpiece assembly contacts 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. - View Dependent Claims (19, 20)
