Abstract

Claims (22)

1. A method of treating acne or rosacea on the skin, said method comprising applying electricity to skin in need of such treatment wherein said electricity is generated by a first conductive electrode in electric communication with a second conductive electrode, wherein both said first conductive electrode and said second conductive electrode are in ionic communication with said skin, wherein the difference of the standard potentials of said first conductive electrode and said second conductive electrode is at least 0.2 V and wherein the electrons that pass between said first conductive electrode and said second conductive electrode are generated as a result of said difference of the standard potentials, wherein said method comprises applying to said skin a device comprising:

a housing having a skin contacting surface;

said first conductive electrode;

said second conductive electrode; and

a carrier;

wherein said first conductive electrode and said second conductive electrode are in ionic communication with said carrier and wherein said carrier is in communication with said skin through said skin contacting surface, and wherein said device is adapted to be affixed to said skin and to deliver electric current from said first conductive electrode, through said carrier, through said skin, and through said carrier to said second conductive electrode.

2. A method of claim 1 , wherein said first conductive electrode comprises zinc.

3. A method of claim 2 , wherein carrier is added to said device by the user prior to application to said skin.

4. A method of claim 3 , wherein said carrier further comprises an anti-acne agent selected from the group comprising tretinoin, isotretinoin, motretinide, adapalene, tazarotene, azelaic acid, retinol, salicylic acid, benzoyl peroxide, resorcinol, sulfur, sulfacetamide, tetracycline, clindamycin, metronidazole, erythromycin, and salts thereof.

5. A method of claim 2 , wherein said housing is a non-woven substrate.

6. A method of claim 5 , wherein carrier is added to said device by the user prior to application to said skin.

7. A method of claim 6 , wherein said carrier further comprises an anti-acne agent selected from the group comprising tretinoin, isotretinoin, motretinide, adapalene, tazarotene, azelaic acid, retinol, salicylic acid, benzoyl peroxide, resorcinol, sulfur, sulfacetamide, tetracycline, clindamycin, metronidazole, erythromycin, and salts thereof.

8. A method of claim 5 , wherein said carrier further comprises an anti-acne agent selected from the group comprising tretinoin, isotretinoin, motretinide, adapalene, tazarotene, azelaic acid, retinol, salicylic acid, benzoyl peroxide, resorcinol, sulfur, sulfacetamide, tetracycline, clindamycin, metronidazole, erythromycin, and salts thereof.

9. A method of claim 2 , wherein said carrier further comprises an anti-acne agent selected from the group comprising tretinoin, isotretinoin, motretinide, adapalene, tazarotene, azelaic acid, retinol, salicylic acid, benzoyl peroxide, resorcinol, sulfur, sulfacetamide, tetracycline, clindamycin, metronidazole, erythromycin, and salts thereof.

10. A method of claim 1 , wherein said housing is a non-woven substrate.

11. A method of claim 10 , wherein said carrier further comprises an anti-acne agent selected from the group comprising tretinoin, isotretinoin, motretinide, adapalene, tazarotene, azelaic acid, retinol, salicylic acid, benzoyl peroxide, resorcinol, sulfur, sulfacetamide, tetracycline, clindamycin, metronidazole, erythromycin, and salts thereof.

12. A method of claim 10 , wherein said carrier further comprises an anti-acne agent selected from the group comprising tretinoin, isotretinoin, motretinide, adapalene, tazarotene, azelaic acid, retinol, salicylic acid, benzoyl peroxide, resorcinol, sulfur, sulfacetamide, tetracycline, clindamycin, metronidazole, erythromycin, and salts thereof.

13. A method of claim 1 , wherein carrier is added to said device by the user prior to application to said skin.

14. A method of claim 13 , wherein said carrier further comprises an anti-acne agent selected from the group comprising tretinoin, isotretinoin, motretinide, adapalene, tazarotene, azelaic acid, retinol, salicylic acid, benzoyl peroxide, resorcinol, sulfur, sulfacetamide, tetracycline, clindamycin, metronidazole, erythromycin, and salts thereof.

15. A method of treating acne or rosacea on the skin, said method comprising applying electricity to skin in need of such treatment wherein said electricity is generated by a first conductive electrode that is an anode in electric communication with a second conductive electrode that is a cathode, wherein both said first conductive electrode and said second conductive electrode are in ionic communication with said skin, wherein the difference of the standard potentials of said first conductive electrode and said second conductive electrode is at least 0.2 V and wherein the electrons that pass between said first conductive electrode and said second conductive electrode are generated as a result of said difference of the standard potentials, wherein said method comprises, wherein said method comprises topically applying a composition to said skin, said composition comprising said first conductive electrode in the form of a particulate and a second conductive electrode partially coated on said particulate.

16. A method of claim 15 , wherein said first conductive electrode comprises zinc and said second conductive electrode comprises silver.

17. A method of claim 15 , wherein said composition further comprises an anti-acne agent selected from the group comprising tretinoin, isotretinoin, motretinide, adapalene, tazarotene, azelaic acid, retinol, salicylic acid, benzoyl peroxide, resorcinol, sulfur, sulfacetamide, tetracycline, clindamycin, metronidazole, erythromycin, and salts thereof.
