  • Patent number: 10111805
    Abstract: A device for face for forming a relatively high potential difference between power terminals of different polarities without a voltage booster circuit to make a lot of current flow through human skin such that function of iontophoresis may be remarkably improved and simultaneously for driving electrically-driven modules of a mask individually without an external power supply to stimulate entirely or partially. The massage device for face includes a mask including an accommodation formed therein and a terminal exposing hole of a terminal for making current to human skin, and at least one electrically-driven module accommodated in the accommodation of the mask, exposing two terminals of different polarities to the outside through the terminal exposing hole, a driving unit having a rotary shaft and a coil wrapping the rotary shaft, and increasing a potential difference between the two terminals using an induced electromotive force of the coil.
