Claim 10:
11. 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, the working end being rigid and 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 the system is configured to deliver fluid from the fluid source through the fluid delivery conduit in a pulsed pattern by generating a pulsed suction along the working end, wherein a delivery of fluid to the working end is performed using only the pulsed suction generated along the working end when the suction source is activated and the working end creates a seal with the skin surface; and
a button or other controller configured to be manipulated by a user and configured to regulate a level of pulsing of the fluid being delivered to the working end from the fluid source;
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.
