Claim:
1. A method of treating a skin surface of a subject, the method comprising: positioning a distal end of a handpiece assembly along a skin surface of a subject, wherein the distal end comprises 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 separated from the annular region by the interior lip; wherein positioning the distal end of the handpiece assembly along a skin surface comprises contacting the peripheral lip and the interior lip with the skin surface; activating a vacuum source when the peripheral lip and the interior lip contact the skin surface to create suction within the annular region, wherein the vacuum source is in fluid communication with at least one vacuum port located along the annular region; at least partially abrading skin tissue using at least one abrasive structure positioned within or along the annular region, wherein at least partially abrading skin tissue occurs by moving the handpiece assembly relative to the skin surface when the distal end of the handpiece assembly is positioned along the skin surface and then the vacuum source is activated; delivering a fluid to the annular region via at least one fluid delivery passage, wherein delivering the fluid to the annular region results from the suction within the annular region by activation of the vacuum source; and delivering air to the interior region via an air delivery passage, wherein delivering air to the interior region is configured to occur simultaneously with creating suction within the annular region and delivering a fluid to the annular region; wherein air is delivered in a pulsed manner to the interior region, and wherein air delivery to the interior region facilitates transfer of fluid at least partially into the skin.
