According to a preferred embodiment of the present invention, a
skin beautifying instrument having a complex function comprises: a head part including a plurality of
electrode terminals that come into contact with the
skin of a user; a body formed to have a constant volume and fixing the
electrode terminals of the head toward the outside; and a
control unit for controlling the operation of the other structural elements, the
control unit applying one or more waveforms selected from the group consisting of
radio frequency,
electrical muscle stimulation,
electroporation, and
ion electrical stimulation to the
electrode terminals and transmitting the waveforms to the
skin of the user. The skin beautifying instrument having a complex function according to a preferred embodiment of the present invention comprising the structure described above can generate a beautifying effect or a
treatment effect on a subject / user, can recognize
skin contact and control energy output, and can apply a
low frequency or a
high frequency to the skin of the subject / user, thereby improving the skin beautifying effect and the
treatment effect on the subject / user. The present invention has the effect of preventing the occurrence of skin burn and
skin injury even when instrument movement is stopped and
skin contact is maintained.
