A cosmetic apparatus comprises a conductive pad; at least one ultrasonic transducer placed on the pad, which is configured to be connected to an ultrasonic wave signal generator to transmit ultrasonic waves to a skin surface through the conductive pad; and a low- and/or moderate-frequency current terminal connected to the conductive pad, which is configured to be connected to a low- and/or moderate-frequency current generator to transmit a low- and/or moderate-frequency current to the skin surface through the conductive pad.
