Abstract

According to some embodiments, a skin treatment assembly comprises a handpiece comprising a distal end, the handpiece comprising a recess or cavity configured to receive a cartridge or other fluid container, a tip configured to be positioned along the distal end of the handpiece, the tip being configured to contact a skin surface of a subject during use, and at least one rollerball configured to extend to or near the tip, wherein the rollerball is configured to be in fluid communication with an interior of a cartridge or other fluid container secured to the handpiece, wherein the at least one rollerball is configured to contact the skin surface of the subject during use and to facilitate the delivery of fluids to said skin surface as the rollerball is moved relative to said skin surface.

Claims

1. A skin treatment assembly, comprising:

a handpiece comprising a distal end;

a tip positioned along the distal end of the handpiece, the tip being configured to contact a skin surface of a subject;

wherein the tip is configured to be placed in fluid communication with a fluid source, wherein the fluid source comprises a fluid container, the fluid container being configured to secure to the handpiece;

a porous member extending to or near the tip, wherein the porous member extends, at least partially, within an interior of the fluid container, and wherein the porous member is configured to be placed in fluid communication with the fluid container, wherein the porous member is configured to facilitate the delivery of fluids to the skin surface; and

at least one suction conduit extending at least partially within or along the handpiece and configured to be placed in fluid communication with a vacuum source to selectively apply suction to the tip during use and to remove spent fluid or other debris from the tip during use.

2. The assembly of claim 1, wherein the porous member comprises a wicking material.

3. The assembly of claim 1, wherein the porous member is positioned along a distal end of the fluid container.

4. The assembly of claim 1, wherein the porous member is in direct fluid communication with an interior of the fluid container.

5. The assembly of claim 1, wherein the porous member is secured to the handpiece.

6. The assembly of claim 1, wherein the porous member is secured to the tip.

7. The assembly of claim 1, further comprising at least one abrasive structure or member located on, near or along the tip, the at least one abrasive structure or member being configured to at least partially abrade skin during use.

8. The assembly of claim 7, wherein the at least one abrasive structure or member comprises a portion or feature comprising a sharp surface.

9. The assembly of claim 1, further comprising a rollerball along a distal end of the porous member.

10. A skin treatment assembly, comprising:

a handpiece comprising a distal end configured to contact a skin surface of a subject;

wherein the handpiece is configured to be placed in fluid communication with a fluid source, wherein the fluid source comprises a fluid container, the fluid container being configured to secure to the handpiece;

a porous member extending to or near the distal end of the handpiece, wherein the porous member extends, at least partially, within an interior of the fluid container, and wherein the porous member is configured to be placed in fluid communication with the fluid container, wherein the porous member is configured to facilitate the delivery of fluids to the skin surface; and

at least one suction conduit extending at least partially within or along the handpiece and configured to be placed in fluid communication with a vacuum source to selectively apply suction to the distal end of the handpiece during use and to remove spent fluid or other debris from the distal end of the handpiece during use.

11. The assembly of claim 10, wherein the porous member comprises a wicking material.

12. The assembly of claim 10, wherein the porous member is positioned along a distal end of the fluid container.

13. The assembly of claim 10, wherein the porous member is in direct fluid communication with an interior of the fluid container.

14. The assembly of claim 10, wherein the porous member is secured to the handpiece.

15. The assembly of claim 10, further comprising at least one abrasive structure or member located on, near or along the distal end of the handpiece, the at least one abrasive structure or member being configured to at least partially abrade skin during use.

16. The assembly of claim 15, wherein the at least one abrasive structure or member comprises a portion or feature comprising a sharp surface.

17. The assembly of claim 10, further comprising a rollerball along a distal end of the porous member.

18. The assembly of claim 10, wherein the porous member comprises at least one material that is configured to be at least partially released upon contact with fluid.
