14. The device of claim 9 , wherein the at least one treatment material comprises at least one of a solid, granular material, gel or concentrated solution, and wherein said at least one treatment material is configured to be dissolved or diluted by a fluid passing to the tip through the at least one fluid delivery conduit.

15. The device of claim 1 , wherein the tip comprises at least one treatment material impregnated or embedded on at least a portion of the tip, said at least one impregnated or embedded material being configured to at least partially dissolve in the presence of at least one fluid delivered to or located at the skin surface being treated.

16. A device for treating a skin surface, comprising:

a handpiece assembly comprising a main body portion and a tip secured to a distal end of said main body portion, said main body portion comprising at least one delivery conduit and at least one waste conduit;

wherein the main body portion of the handpiece assembly comprises a recess, said recess being configured to receive a cartridge, wherein the recess extends to an exterior of the main body portion, permitting the cartridge to be selectively removed from or inserted into the recess of the handpiece assembly directly from an exterior of the device during a skin treatment procedure, thereby permitting fluid or other material delivered from a cartridge to the skin surface to be selectively changed during a procedure;

wherein an interior portion of a cartridge secured within the recess of the main body portion is placed in fluid communication with the fluid delivery conduit when said cartridge is secured within the recess; and

wherein at least a portion of the tip is configured to contact the skin surface when in use;
