Pore Peeling Facial Device Used once, but no longer needed as I bought a different suction device. This peeling beauty device uses ultrasonic waves (approx. 27,000 times per second) and ion extraction to remove dirt and dead skin cells from pores. It also features a "Moist Lift Mode" using ion introduction and ultrasonic tapping to tighten skin and promote the absorption of beauty ingredients. Please understand that this is a used item before purchasing.
