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.
