An ultrasonic skin scrubber is a handheld device used in skincare to cleanse and exfoliate the skin. It uses high-frequency sound waves to create vibrations that help remove dead skin cells, dirt, and oil from the skin's surface. This process can enhance skin texture and promote a clearer complexion. The device typically features a flat metal tip that glides over the skin, making it easy to use at home or in professional settings. Many people find that using an ultrasonic skin scrubber can improve the effectiveness of their skincare products by allowing better absorption into the skin.
