Abstract

The present invention features a method of treating pores on the skin by applying to skin in need of such treatment a device including a housing having a skin contacting surface, a first conductive electrode, a second conductive electrode, and a carrier; wherein the first conductive electrode is in electric communication with the second conductive electrode, wherein the first conductive electrode is in ionic communication with the carrier, wherein the carrier is in communication with the skin contacting surface, and wherein the skin contacting surface is placed in contact with the skin.

Claims

1. A method of treating pores on the skin, said method comprises topically applying a composition to said skin, said composition comprising a first conductive electrode in the form of a particulate and a second conductive electrode partially coated on said particulate wherein the difference of the standard potentials of said first conductive electrode and said second conductive electrode is at least 0.2 V, wherein said first conductive electrode and said second conductive electrode are in electric communication, wherein both said first conductive electrode and said second conductive electrode are in ionic communication with said skin, and wherein said method of treating pores on the skin is selected from the group consisting of cleansing pores on the skin, reducing sebum on the skin, reducing the appearance of blackheads on the skin, and reducing the appearance of pores on the skin.

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

3. A method of claim 1, wherein said composition further comprises salicylic acid or a salt thereof.

4. A method of treating pores on the skin, said method comprising affixing to skin in need of such treatment a device comprising:
