The handpiece assembly includes a fluid delivery conduit and a waste conduit. In addition, the cartridge is coupled to the handpiece assembly with the interior cavity of the cartridge being in fluid communication with the fluid delivery conduit. Further, the tip is configured to contact the skin. The tip comprises a peripheral lip, a first opening in fluid communication with the fluid delivery conduit, a second opening in fluid communication with the waste conduit and an abrasive element. The first opening, the second opening and the abrasive element of the tip are generally positioned within the peripheral lip. ## Claims ### Claim 1 A container configured for use with a skin treatment handpiece, the container comprising: a main cylindrical portion; a closure portion comprising a penetrable member; wherein the closure portion is secured to the main cylindrical portion to define an interior of the container; and a treatment material contained within the interior of the container; wherein the container is configured to be positioned within a receiving area of the skin treatment handpiece, the receiving area located along a main body portion of the skin treatment handpiece such that a user can grasp and manipulate the main body portion of the skin treatment handpiece with the container secured within the receiving area during use; wherein the penetrable member is configured to be pierced, punctured or otherwise compromised by a spike of the skin treatment handpiece when the container has been advanced to a depth of the receiving area of the skin treatment handpiece; wherein the treatment material is configured to be placed in fluid communication with the spike of the skin treatment handpiece when the spike has pierced the penetrable member; wherein the container is configured so that advancement of the container to a desired depth of the receiving area of the skin treatment handpiece produces a feedback to notify a user that the container has been property secured within the receiving area of the skin treatment handpiece; and wherein the penetrable member is resealable when the container is removed from the receiving area of the skin treatment handpiece, thereby reducing a likelihood of the treatment material leaking from the interior of the container. ### Claim 2 (depends on 1) The container of claim 1, wherein the feedback is audible. ### Claim 3 (depends on 1) The container of claim 1, wherein the feedback comprises a positive engagement mechanism. ### Claim 4 (depends on 1) The container of claim 1, wherein the penetrable member comprises a septum or a membrane. ### Claim 5 (depends on 1) The container of claim 1, wherein the penetrable member comprises at least one flexible material. ### Claim 6 (depends on 1) The container of claim 1, wherein the penetrable member comprises at least one of a rubber, a plastic and a paper material. ### Claim 7 (depends on 1) The container of claim 1, wherein the main cylindrical portion comprises glass and the closure portion comprises a metal. ### Claim 8 (depends on 1) The container of claim 1, wherein the closure portion comprises a metal. ### Claim 9 (depends on 1) The container of claim 1, wherein the closure portion is secured to an end of main cylindrical portion using a crimped connection. ### Claim 10 (depends on 1) The container of claim 1, wherein the closure portion is secured to an end of main cylindrical portion using at least one of a threaded connection, a snap connection, a fastener and an adhesive. ### Claim 11 (depends on 1) The container of claim 1, further comprising a port along a proximal end of the main cylindrical portion, the port being configured to be coupled to a fluid conduit that places the container in fluid communication with a separate fluid source. ### Claim 12 (depends on 11) The container of claim 11, wherein the separate fluid source comprises a manifold system to which two or more fluid bottles are configured to secure. ### Claim 13 A method of treating skin, the method comprising: positioning a container within a receiving area of a handpiece, the receiving area located along a main body portion of the handpiece; wherein the container comprises a main cylindrical portion, a closure portion and a treatment material contained within an interior defined by the main cylindrical portion and the closure portion; and wherein the container is configured to be positioned within the receiving area of the handpiece, wherein a user can grasp and manipulate the main body portion of the handpiece with the container positioned within the receiving area during use; and placing the treatment material contained in the interior of the container in fluid communication with an interior passage of the handpiece by advancing the container within the receiving area so that a penetrating member of the handpiece punctures a penetrable member of the closure portion; and receiving a feedback when the container has been secured within the receiving area of the handpiece. ### Claim 14 (depends on 13) The method of claim 13, wherein the feedback is audible. ### Claim 15 (depends on 13) The method of claim 13, wherein the feedback comprises a positive engagement mechanism. ### Claim 16 (depends on 13) The method of claim 13, further comprising removing the container from the receiving area, wherein a penetrable member is configured to reseal the interior of the container when the container is removed from the handpiece. ### Claim 17 A method of treating skin, the method comprising: positioning a container within a receiving area of a skin treatment handpiece; wherein the container comprises a main cylindrical portion, a closure portion comprising a resealable penetrable member, and a treatment material contained within an interior defined by the main cylindrical portion and the closure portion; and wherein the container is configured to be positioned within the receiving area of the skin treatment handpiece; and placing the treatment material contained in the interior of the container in fluid communication with an interior passage of the skin treatment handpiece by advancing the container within the receiving area so that a penetrating member of the skin treatment handpiece punctures the resealable penetrable member of the closure portion; wherein the container is configured so that advancement of the container to a desired depth of the receiving area of the skin treatment handpiece produces a feedback to notify a user that the container has been property secured within the receiving area of the skin treatment handpiece. ### Claim 18 (depends on 17) The method of claim 17, wherein the feedback is audible. ### Claim 19 (depends on 17) The method of claim 17, wherein the feedback comprises a positive engagement mechanism. ### Claim 20 (depends on 17) The method of claim 17, further comprising removing the container from the receiving area, wherein a penetrable member is configured to reseal the interior of the container when the container is removed from the skin treatment handpiece.
