Abstract

According to some embodiments, a microdermabrasion device for treating skin comprises a handpiece assembly having a distal end and a proximal end. The handpiece assembly includes at least one delivery conduit and at least one waste conduit. The microdermabrasion device additionally comprises a tip configured to be positioned along the distal end of the handpiece assembly, wherein the tip is adapted to contact skin surface. In several embodiments, the tip comprises a lip, a first opening in fluid communication with the fluid delivery conduit and a second opening in fluid communication with the waste conduit. In one embodiment, the device includes one or more abrasive elements positioned along a distal end of the tip, wherein the abrasive elements are configured to selectively remove skin as the tip is moved relative to a skin surface.

Claims

1. A method for treating a skin surface, comprising:

delivering fluid to a tip of a handpiece assembly, wherein the handpiece assembly comprises at least one delivery conduit through which the fluid is configured to be delivered;

wherein the at least one delivery conduit is in fluid communication with a fluid source; and

providing at least one time-release material to the skin surface by delivering fluid to the tip, the at least one time-release material being configured to have an effect on the skin surface after a time period after providing the at least one time-release material to the skin surface;

wherein the at least one time-release material is positioned on the tip, the fluid at least partially dissolving the at least one time-release material when the fluid is delivered to the tip.

2. The method of claim 1, wherein the time period is 1 hour.

3. The method of claim 1, wherein the time period is 48 hours.

4. The method of claim 1, further comprising abrading the skin tissue using at least one abrasive structure or element positioned along the tip.

5. The method of claim 4, wherein the at least one abrasive structure or element comprises a protruding member, a spiral ridge or an abrasive surface.

6. The method of claim 4, wherein the at least one abrasive structure or element comprises an abrasive disc configured to be separated from the tip.

7. The method of claim 1, wherein the at least one time-release material comprises a plurality of microcapsules, capsules or other enclosures configured to release their internal contents at various times following delivery to the skin surface.

8. The method of claim 1, wherein the at least one time-release material comprises salicylic acid.

9. The method of claim 1, wherein the at least one time-release material comprises a peptide, a growth factor, a sunblocking agent, an antioxidant, a hydration agent, a skin lightening agent or a skin tightening agent.

10. The method of claim 1, wherein the at least one time-release material is impregnated along at least a portion of the tip.

11. A method for treating a skin surface, comprising:

providing at least one time-release material to the skin surface using a handpiece assembly;

wherein the at least one time-release material is configured to have an effect on the skin surface after a time period after providing the at least one time-release material to the skin surface; and

wherein the at least one time-release material is positioned on a tip of the handpiece assembly, and wherein a fluid is configured to at least partially dissolve the at least one time-release material when said fluid is delivered to the tip.

12. The method of claim 11 wherein the at least one time-release material is delivered with a fluid through a delivery conduit of the handpiece assembly.

13. The method of claim 11, wherein the time period is 1 hour.

14. The method of claim 11, wherein the time period is 48 hours.

15. The method of claim 11, further comprising abrading the skin tissue using at least one abrasive structure or element positioned along a distal end of the handpiece assembly.

16. The method of claim 11, wherein the at least one time-release material comprises a plurality of microcapsules, capsules or other enclosures configured to release their internal contents at various times following delivery to the skin surface.

17. The method of claim 11, wherein the at least one time-release material comprises at least one of an acid, a peptide, a growth factor, a sunblocking agent, an antioxidant, a hydration agent, a skin lightening agent and a skin tightening agent.

18. A method for treating a skin surface, comprising:

delivering fluid to a tip of a handpiece assembly, wherein the handpiece assembly comprises at least one delivery conduit through which the fluid is configured to be delivered;

wherein the at least one delivery conduit is in fluid communication with a fluid source; and

providing at least one time-release material to the skin surface by delivering fluid to the tip, the at least one time-release material being configured to have an effect on the skin surface after a time period after providing the at least one time-release material to the skin surface;

wherein the at least one time-release material is impregnated along at least a portion of the tip.
