Claim 0:
1. 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 including a main body portion and a tip positioned along a distal end of the main body portion, the tip comprising a peripheral lip configured to contact the skin surface and create a seal with the skin surface during use;
a fluid delivery conduit configured to place the tip in fluid communication with a fluid source, wherein fluid is configured to be delivered to the tip through the fluid delivery conduit and a first opening in fluid communication with the fluid delivery conduit;
a suction conduit configured to place the tip in fluid communication with a suction source, wherein, simultaneously, (1) spent fluid and debris are configured to be removed away from the tip through the suction conduit and a second opening in fluid communication with the suction conduit, and (2) fluid is configured to be delivered to the tip through the fluid delivery conduits and a first opening when the suction source is activated and the peripheral lip creates a seal with the skin surface;
wherein the system is configured to deliver fluid from the fluid source to the tip using a pulsing of negative pressure created by the suction source;
a control module configured to regulate the pulsed pattern of fluid; and
a controller operatively coupled to the control module, wherein manipulation of the controller by a user regulates a level of pulsing of fluid during use;
wherein the tip 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; and
wherein the first opening, the second opening and the at least one skin abrading member are positioned within an interior of the peripheral lip.
