Abstract

The present invention relates to a method of treating the skin of a subject, the method including the steps of: (a) accessing a sample of interstitial fluid from the skin of the subject; (b) measuring the amount of a skin analyte in the sample; and (c) applying a skin care product to the subject to alter the amount of the skin analyte in the skin of the subject.

Claims

1. A method of treating the skin health of a subject, said method comprising the steps of:

(a) accessing a sample of interstitial fluid from the skin of said subject;

(b) measuring the amount of a skin analyte in said sample; and

(c) applying a skin care product to said subject to alter the amount of said skin analyte in the skin of said subject.

2. A method of claim 1, wherein said method comprises creating an opening in the stratum corneum of the skin of said patient and accessing said sample through said opening.

3. A method of claim 2, wherein said opening is created with a needle, a blade, a laser, or an electric arc.

4. A method of claim 3, wherein said opening is created with a laser.

5. A method of claim 4, wherein said method further comprises comparing the amount of said analyte to a reference standard.

6. A method of claim 5, wherein said skin care product comprises a vitamin.

7. A method of claim 4, wherein said skin care product comprises a vitamin.

8. A method of claim 3, wherein said sample is extracted through said opening under negative pressure.

9. A method of claim 8, wherein said skin analyte is a vitamin, an immunoglobulin, an insulin-like growth factor, an interleukin, an interleukin receptor antagonist, or a metalloproteinase.

10. A method of claim 8, wherein said skin analyte is vitamin C.

11. A method of claim 10, wherein said method further comprises comparing the amount of said analyte to a reference standard.

12. A method of claim 11, wherein said skin care product comprises a vitamin.

13. A method of claim 10, wherein said skin care product comprises a vitamin.

14. A method of claim 8, wherein said method further comprises comparing the amount of said analyte to a reference standard.

15. A method of claim 14, wherein said skin care product comprises a vitamin.

16. A method of claim 8, wherein said skin care product comprises a vitamin.

17. A method of claim 2, wherein said skin care product comprises a vitamin.

18. A method of claim 2, wherein said sample is extracted through said opening under negative pressure.

19. A method of claim 2, wherein said method further comprises comparing the amount of said analyte to a reference standard.

20. A method of claim 19, wherein said skin care product comprises a vitamin.

21. A method of claim 1, wherein said skin analyte is a vitamin, an immunoglobulin, an insulin-like growth factor, an interleukin, an interleukin receptor antagonist, or a metalloproteinase.

22. A method of claim 1, wherein said skin analyte is vitamin C.

23. A method of claim 1, wherein said method further comprises comparing the amount of said analyte to a reference standard.

24. A method of claim 23, wherein said skin care product comprises a vitamin.

25. A method of claim 1, wherein said skin care product comprises a vitamin.
