Abstract

The invention features a method of administering a skin benefit agent to an expanse of skin, wherein the method includes: (a) contacting the expanse of skin with a skin benefit agent; and (b) contacting the skin benefit agent on the expanse of skin with an apparatus having a output power to the skin of greater than about 0.2 W, the apparatus including: a skin-contactable element having a skin-contactable surface; a motor; and a transfer member for transferring mechanical energy from the motor to the skin-contactable element in order to provide periodic motion to the skin-contactable surface; wherein the skin-contactable surface contacts the skin-benefit agent.

Claims

1. A method of administering a skin benefit agent to an expanse of skin, said method comprising:

(a) contacting said expanse of skin with a skin benefit agent; and

(b) contacting said skin benefit agent on said expanse of skin with an apparatus having a output power to the skin of greater than about 0.2 W, said apparatus comprising;

(i) a skin-contactable element having a skin-contactable surface;

(ii) a motor; and

(iii) a transfer member for transferring mechanical energy from said motor to said skin-contactable element in order to provide periodic motion to said skin-contactable surface;

wherein said skin-contactable surface contacts said skin-benefit agent.

2. The method of claim 1, wherein said expanse of skin is located on the face.

3. The method of claim 1, wherein said apparatus delivers a total output power of greater than about 0.25 W to said expanse of skin.

4. The method of claim 1, wherein said apparatus delivers a total output power of greater than about 0.2 W to said expanse of skin.

5. The method of claim 1, wherein said contacting of said expanse of skin with said skin-contactable surface delivers to said expanse of skin a power density of at least 110 W/m².

6. The method of claim 1, wherein said contacting of said expanse of skin with said skin-contactable surface delivers to said expanse of skin a power density of at least 125 W/m².

7. The method of claim 1, wherein said contacting of said expanse of skin with said skin-contactable surface delivers to said expanse of skin a power density of at least 110 W/m².

8. The method of claim 1, wherein said apparatus further comprises an energy storage element coupled to said motor for delivering stored energy from said energy storage element to said motor.

9. The method of claim 1, wherein said skin-contactable surface contacts said expanse of skin for a period of from about 30 seconds to about 5 minutes.

10. The method of claim 1, wherein said periodic motion comprises reciprocating motion.

11. The method of claim 1, wherein said periodic motion comprises tapping motion.

12. The method of claim 1, wherein said periodic motion comprises orbital motion.

13. The method of claim 1, wherein said skin-contactable surface moves with a frequency in a range from about 1500 cycles per minute to about 5000 cycles per minute.

14. The method of claim 1, wherein said skin-contactable surface moves with an amplitude in a range from about 0.5 mm to about 10 mm.

15. The method of claim 14, wherein said amplitude is in a range from about 1 mm to about 5 mm.

16. The method of claim 1, wherein said skin-contactable surface has a projected area less than about 20 cm².

17. The method of claim 16, wherein said projected area is less than about 15 cm².

18. The method of claim 16, wherein said projected area is less than about 10 cm².

19. The method of claim 1, wherein (i) said skin-contactable surface comprises a first sub-surface and a second subsurface and (ii) said method further comprises imparting a first periodic motion to said first sub-surface and a second periodic motion to said second subsurface such that said second subsurface moves in a disjoint relationship with respect to said first sub-surface.

20. The method of claim 19, wherein said first periodic motion and said second periodic motion are characterized by a phase difference that is non-zero.

21. The method of claim 1 wherein said benefit agent is selected from a group consisting of reflectants;

film forming polymers;

amino acids and their derivatives;

allergy inhibitors;

anti-acne agents;

anti-aging agents;

anti-wrinkling agents, antiseptics;

combinations thereof.

22. The method of claim 1 wherein said benefit agent is selected from a group consisting of neo-collagen enhancers, skin-firming agents, depigmenting agents, and combinations thereof.

23. The method of claim 1 wherein said benefit agent is selected from a group consisting of vitamin A and its derivatives;

vitamin C and its derivatives;

copper containing peptides; and

combinations thereof.

24. The method of claim 1 wherein said benefit agent is an alkanolamine.

25. The method of claim 1 wherein said benefit agent is dimethyl aminoethanol.

26. The method of claim 22 wherein the depigmenting agent is selected from the group consisting of retinoids, kojic acid, soy extract and its derivatives, hydroquinone, and combinations thereof.

27. The method of claim 1 wherein said benefit agent is comprised within a fluid composition.

28. The method of claim 27 wherein said fluid composition is a liquid, gel, or emulsion.

29. The method of claim 1 wherein said skin-contactable element comprises said benefit agent and said benefit agent is transferred from said skin-contactable element to said expanse of skin.
