Claim 7:
8. A skin treatment system configured to at least partially remove an outer layer or an epidermis of a skin surface using mechanical exfoliation, the system comprising:
a handpiece assembly comprising a working end configured to contact the skin surface and create a seal with the skin surface during use;
a suction conduit configured to place the working end in fluid communication with a suction source, wherein the suction conduit is configured to remove spent fluid from the working end when the suction source is activated and the working end creates a seal with the skin surface;
a fluid delivery conduit configured to place the working end in fluid communication with a fluid source, wherein fluid is configured to be delivered through the fluid delivery conduit to the working end in a pulsed pattern by generating a pulsed suction along the working end, wherein the pulsed suction and a delivery of fluid to the working end is accomplished using the pulsed suction when the suction source is activated and the working end creates a seal with the skin surface, wherein delivery of fluid to the working end using the pulsed pattern assists with penetration of fluid into the skin surface; and
a button or other controller configured to regulate a level of pulsing of the fluid from the fluid source to the working end;
wherein the working end comprises at least one skin abrading member configured to abrade, at least partially, the epidermis when the handpiece assembly is moved relative to skin tissue.
