1. A cosmetic device comprising:
a body from which a first head portion and a second head portion protrude in directions different from each other;
a front assembly disposed on the first head portion;
a rear assembly disposed on the second head portion; and
an iontophoresis electrode disposed to be spaced apart from the front assembly and the rear assembly on an outer surface of the body,
wherein the front assembly comprises:
an inner electrode;
an outer electrode disposed outside the inner electrode; and
an ultrasonic vibrator disposed on a rear surface of the inner electrode to generate ultrasonic waves,
wherein the rear assembly comprises:
a thermoelectric element; and
a cooling cover cooled by the thermoelectric element,
wherein the cosmetic device further comprising a controller configured to perform a care mode in at least one cycle,
wherein the at least one cycle of the care mode comprises:
a first mode, in which a high frequency is output from the outer electrode;
a second mode which is performed after the first mode and in which ultrasonic waves generated from the ultrasonic vibrator are output through the inner electrode, and microcurrent is output from the outer electrode;
a third mode which is performed after the second mode and in which a high frequency is output from the outer electrode;
a fourth mode which is performed after the third mode and in which ultrasonic waves generated from the ultrasonic vibrator are output through the inner electrode, and microcurrent having a reverse phase with respect to the second mode is output from the outer electrode;
a fifth mode which is performed after the fourth mode and in which a high frequency is output from the outer electrode; and
a sixth mode which is performed after the fifth mode and in which ultrasonic waves generated from the ultrasonic vibrator are output through the inner electrode and galvanic current are output from the inner electrode at the same time.
