The present invention relates to an electric module for stimulating the skin, which can increase a potential difference between power terminals having different polarities without requiring a separate voltage booster circuit, thereby significantly enhancing an iontophoresis function by applying a large quantity of electric current on the skin of the human body. The electric module for stimulating the skin, according to the present invention, comprises: a base portion on one surface of which the power terminals having different polarities for actuating an oscillator are formed, the power terminals mutually connecting with the base portion with the skin of the human body as a conductor an oscillator which is installed on at least one surface of the base portion a driving portion, which is installed on the base portion, comprising a rotary shaft for providing driving force to the oscillator and a coil that positions the rotary shaft on the inside a driving switch, which is installed at a power input end of the driving portion, for turning power of the driving portion on/off a control portion for controlling the on/off of the driving switch so as to control the state of operation of the driving portion and the state of oscillation of the oscillator in response to the operation of the driving portion and an inductance processing portion having an input end, which is connected in parallel between the driving switch and the driving portion, for relaying electric energy that is generated from the coil around the rotary shaft to an output end of the driving portion, when the driving portion idles in accordance with an off operation of the driving switch.본 발명은 서로 다른 극성의 전원단자 간 전위차(電位差)를 별도의 승압회로 없이 크게 하고, 이를 통해 인체의 피부에 보다 많은 전류를 흘려보내 이온영동법의 효과를 높이는 피부 자극용 전동모듈에 관한 것으로서, 본 발명에 따른 피부 자극용 전동모듈은, 진동자의 구동을 위한 서로 다른 극성의 전원단자가 일면에 각각 형성되고, 상기 전원단자가 인체의 피부를 도전체로 상호 접속하는 베이스부와, 상기 베이스부의 적어도 일면에 설치되는 진동자와, 상기 진동자에 동력을 제공하기 위한 회전축 및 상기 회전축을 내측에 위치시키는 코일을 구비하는 상태로 상기 베이스부에 설치되는 구동부와, 상기
