Abstract

Method for regulating the condition of mammalian skin comprising the steps of applying a first personal care composition to an area of skin where regulation is desired, wherein the first personal care composition comprises at least one skin care active selected from the group consisting of niacinamide, salicylic acid, peptides, N-acetyl glucosamine, panthenol, butylated hydroxytoluene, N-acyl amino acid compounds, hexamidine, green tea, ascorbyl glucoside, hexanediol, pentanediol, a skin lightening agent, a heat shock protein potentiator, and mixtures thereof, and delivering energy to the area of skin by contacting the skin with an energy delivery device for a treatment period of at least 2½ minutes, wherein the energy delivery device comprises a skin-contacting surface that is controllably heatable to a temperature of from 37° C. to 50° C.

Claims

1. A method for regulating the condition of mammalian skin comprising the steps of:

(a) applying a first personal care composition to an area of skin where regulation is desired, wherein the first personal care composition comprises at least one skin care active selected from the group consisting of niacinamide, salicylic acid, pentapeptides, N-acetyl glucosamine, panthenol, butylated hydroxytoluene, N-acyl amino acid compounds, hexamidine, green tea, ascorbyl glucoside, hexanediol, pentanediol, a skin lightening agent, a heat shock protein potentiator, and mixtures thereof; and

(b) delivering energy to the area of skin by contacting the skin with an energy delivery device for a treatment period of at least 2½

minutes, wherein the energy delivery device comprises a skin-contacting surface that is controllably heatable to a temperature of from 37°

C. to 50°

C.

2. The method of claim 1, further comprising the step of applying a second personal care composition to the area of skin, wherein the second personal care composition comprises at least one skin care active selected from the group consisting of ascorbic acid, creatine, creatinine, soy extract, retinol, salicylic acid, arbutin, tranexamic acid, hydroxy acids, niacinamide, hexamidine, peptides, N-acetyl glucosamine, N-acyl amino acid compounds, green tea, ascorbyl glucoside, a sunscreen, and mixtures thereof.

3. The method of claim 2, wherein at least one skin care active in the first composition is the same as at least one skin care active in the second composition.

4. The method of claim 2, wherein the first personal care composition comprises a conditioning agent, and the second personal care composition comprises a sunscreen.

5. The method of claim 2, wherein the first personal care composition comprises niacinamide, and the second personal care composition comprises a sunscreen.

6. The method of claim 2, wherein the first personal care composition comprises N-acetyl glucosamine, and the second personal care composition comprises a sunscreen.

7. The method of claim 2, wherein the first personal care composition comprises a warming agent and the second personal care composition comprises a cooling agent.

8. The method of claim 2, wherein the first composition further comprises a sensorial evoking agent which is activated by the energy delivered by the energy delivery device.

9. The method of claim 1, wherein the energy delivery device is substantially stationary during the treatment period.

10. The method of claim 1, wherein at least a portion of the energy delivery device is moved across the surface of the skin during the treatment period.

11. The method of claim 1, wherein the energy is selected from the group consisting of heat, electromagnetic, light, radio-frequency, radio-frequency energy in the absence of light-based energy, and combinations thereof.

12. The method of claim 11, wherein the energy is heat energy.

13. The method of claim 11, wherein the energy is light energy emitted from a laser.

14. The method of claim 11, wherein the energy applied to the area of skin during the treatment period is from 1 J/cm² to 100 J/cm².

15. The method of claim 1, wherein the first personal care composition is applied to the area of skin at least twice daily.

16. The method of claim 1, wherein the energy is applied at least once per week.

17. The method of claim 1, further comprising the step of applying to the area of skin a third, pre-conditioning composition, wherein the third composition is applied at least 24 hours prior to applying energy to the skin.

18. The method of claim 1, wherein regulating the condition of skin comprises reducing the appearance of fine lines, reducing the appearance of wrinkles, reducing sagging, reducing hyperpigmentation, and combinations thereof.

19. A method of reducing the appearance of fine lines and/or wrinkles in mammalian skin, comprising the steps of:

(a) applying a first personal care composition to an area of skin exhibiting fine lines and/or wrinkles, wherein the first personal care composition comprises at least one skin care active selected from the group consisting of niacinamide, a pentapeptide, N-acetyl glucosamine, and mixtures thereof,

(b) delivering energy to the area of skin by contacting the skin with an energy delivery device for a treatment period of at least 21/2 minutes, wherein the energy delivery device comprises a skin-contacting surface that is controllably heatable to a temperature of from 37°

C. to 50°

C.;

(c) applying a second personal care composition to the area of skin, wherein the second personal care composition comprises a cooling agent.

20. A method of reducing the appearance of hyperpigmentation in mammalian skin, comprising the steps of:

(a) applying a first personal care composition to an area of skin exhibiting hyperpigmentation, wherein the first personal care composition comprises at least one skin lightening agent selected from the group consisting of N-undecylenoyl-L-phenylalanine, niacinamide, and combinations thereof,

(b) delivering energy to the area of skin by contacting the skin with an energy delivery device for a treatment period of at least 21/2 minutes, wherein the energy delivery device comprises a skin-contacting surface that is controllably heatable to a temperature of from 37°

C. to 50°

C.;

(c) applying a second personal care composition to the area of skin, wherein the second personal care composition comprises a cooling agent.

21. An article of commerce is provided comprising:

a first personal care composition comprising a first skin care active;

a second personal care composition comprising a second skin care active;

an energy delivery device; and

instructions that direct a user to use the first skin care composition together with an energy delivery device during a treatment period, and to use the second skin care composition between successive treatment periods.
