The present invention features a method of treating acne or rosacea on the skin by 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 the first conductive electrode and the second conductive electrode are in ionic communication with the skin, wherein the difference of the standard potentials of the first conductive electrode and the second conductive electrode is at least 0.2 V and wherein the electrons that pass between the first conductive electrode and the second conductive electrode are generated as a result of such difference of the standard potentials.본 발명은 전기화학적으로 발생된 아연 이온을 피부에 적용함으로써 여드름 또는 장미여드름을 치료하는 방법에 관한 것이다. 하나의 양태에서, 당해 방법은 아연 함유 양극을 포함하는 기구를 국소 적용함을 포함한다.
