A skin management device comprising: a main body portion having a suction cup; an electrode tip provided on an inner circumferential surface of the suction cup; a high frequency generation portion configured to apply a high frequency to the electrode tip; a suction pump configured to provide suction power to the suction cup; a contact sensor provided on the inner circumferential surface of the suction cup and disposed around the electrode tip; and a controller configured to control operations of the high frequency generation portion and the suction pump, wherein the suction pump operates to suck a user's skin into the suction cup, and when the user's skin contacts the contact sensor, the contact sensor transmits a contact signal to the controller, and the controller, when receiving the contact signal, recognizes suction of the user's skin and operates the high frequency generation portion to apply a high frequency to the user's skin through the electrode tip, characterized in that: the contact sensor comprises a first contact sensor and a second contact sensor, the first contact sensor is disposed at a position lower than the second contact sensor, the first contact sensor generates a first contact signal, the second contact sensor generates a second contact signal, and the controller, when receiving the first contact signal, operates the high frequency generation portion, and when receiving the second contact signal, controls operation of the suction pump. a main body portion having a suction cup; an electrode tip provided on an inner circumferential surface of the suction cup; a high frequency generation portion configured to apply a high frequency to the electrode tip; a suction pump configured to provide suction power to the suction cup; a contact sensor provided on the inner circumferential surface of the suction cup and disposed around the electrode tip; and a controller configured to control operations of the high frequency generation portion and the suction pump, wherein the suction pump operates to suck a user's skin into the suction cup, and when the user's skin contacts the contact sensor, the contact sensor transmits a contact signal to the controller, and the controller, when receiving the contact signal, recognizes suction of the user's skin and operates the high frequency generation portion to apply a high frequency to the user's skin through the electrode tip, characterized in that: the contact sensor comprises a first contact sensor and a second contact sensor, the first contact sensor is disposed at a position lower than the second contact sensor, the first contact sensor generates a first contact signal, the second contact sensor generates a second contact signal, and the controller, when receiving the first contact signal, operates the high frequency generation portion, and when receiving the second contact signal, controls operation of the suction pump. the contact sensor comprises a first contact sensor and a second contact sensor, the first contact sensor is disposed at a position lower than the second contact sensor, the first contact sensor generates a first contact signal, the second contact sensor generates a second contact signal, and the controller, when receiving the first contact signal, operates the high frequency generation portion, and when receiving the second contact signal, controls operation of the suction pump.
