Abstract

An apparatus for treating skin has a console with a user input device and a handpiece assembly. The handpiece assembly is configured to treat skin. A fluid line provides fluid communication between the console and the handpiece assembly. A manifold system is coupled to the console and controlled by the user input device. The manifold system is configured to hold releasably a plurality of fluid sources and deliver fluid from at least one of the plurality of fluid sources to the handpiece assembly.

Claims

1. (canceled)

2. A method of extracting substances from a skin surface of a subject, comprising:

securing a tip along a distal end of a handpiece, the handpiece comprising a vacuum passage, wherein the vacuum passage is in fluid communication with a vacuum source and the tip when the tip is secured to the handpiece;

activating the vacuum source to create suction within the vacuum passage;

positioning the tip along the skin of the subject, wherein the suction along the tip helps draw a portion of the subject'"'"'s skin toward the tip; and

applying a lifting treatment material to the subject'"'"'s skin surface, wherein the lifting treatment material facilitates extraction of substances from skin; and

at least partially twisting the handpiece while the tip is positioned against the subject'"'"'s skin, wherein at least partially twisting the handpiece helps extract substances from skin.

3. The method of claim 2, wherein the lifting treatment material comprises an acid.

4. The method of claim 2, wherein the lifting treatment material comprises salicylic acid.

5. The method of claim 2, wherein the substances extracted from the skin surface comprise at least one of blackheads, sebum, oil and dead skin.

6. The method of claim 2, wherein the lifting treatment material is delivered to the tip via a fluid passage of the handpiece.

7. The method of claim 2, further comprising pressing the tip against the skin surface of a subject to facilitate the extraction of substances from skin.

8. The method of claim 2, further comprising at least partially abrading the skin surface, wherein the tip comprises at least one cutting or abrading structure to facilitate said abrading when the tip is moved relative to the skin surface.

9. The method of claim 8, wherein the at least one cutting or abrading structure comprises a curved shape.

10. The method of claim 8, wherein the at least one cutting or abrading structure comprises a spiral-like pattern.

11. The method of claim 2, further comprising applying at least one follow-up treatment material to the subject'"'"'s skin.

12. The method of claim 11, wherein the follow-up treatment material comprises at least one of the following:

an antioxidant, a bacteria-targeting material and a growth factor.

13. The method of claim 2, further comprising massaging the skin surface, wherein the tip comprises at least one structure configured to massage skin when tip is moved relative to the skin surface.

14. A method of extracting substances from a skin surface of a subject, comprising:

positioning a tip of a handpiece along the skin of the subject, wherein the handpiece comprises a suction passage, wherein the suction passage is configured to be placed in fluid communication with a suction source;

activating the suction source to create suction within the suction passage and to help draw the subject'"'"'s skin surface toward the tip; and

at least partially twisting the handpiece while the tip is positioned against the subject'"'"'s skin, wherein at least partially twisting the handpiece helps extract undesirable substances from skin.

15. The method of claim 14, further comprising applying a lifting treatment material to the subject'"'"'s skin surface, wherein the lifting treatment material facilitates extraction of undesirable substances from skin.

16. The method of claim 15, wherein the lifting treatment material comprises salicylic acid or another acid.

17. The method of claim 14, further comprising at least partially abrading and/or massaging the skin surface, wherein the tip comprises at least one structure to facilitate said abrading or massaging when the tip is moved relative to the skin surface.

18. The method of claim 17, wherein the at least one structure comprises a spiral-like or other curved shape.

19. The method of claim 14, further comprising applying at least one follow-up treatment material to the subject'"'"'s skin.

20. A method of extracting substances from a skin surface of a subject, comprising:

applying a lifting treatment material to the subject'"'"'s skin surface, wherein the lifting treatment material facilitates extraction of substances from skin;

positioning a tip of a handpiece along the skin of the subject, wherein the handpiece comprises a suction passage, wherein the suction passage is configured to be placed in fluid communication with a suction source;

activating the suction source to create suction within the suction passage and to help draw the subject'"'"'s skin surface toward the tip; and

pressing the tip against the skin surface of a subject to facilitate the extraction of substances from skin.

21. The method of claim 20, further comprising at least partially twisting the handpiece while the tip is positioned against the subject'"'"'s skin, wherein at least partially twisting the handpiece helps extract substances from skin.
