Abstract
Disclosed are: a skin care device which determines whether, on the basis of a voltage fluctuation according to contact with the skin, the skin care device has been rubbed, and which blocks the output of current through an electrode when rubbing does not occur for at least a set time; and a control method therefor. The disclosed skin care device determines the state of the skin care device on the basis of sensing voltage corresponding to a change in current of a transformation module according to the outputting of alternating current into the skin through contact electrodes, and blocks the output of current of an electrode module if the skin care device is in a fixed state.
