Devices for treating skin using treatment materials located along a tip
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.
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.
