This advanced face roller combines constant heating, Bio-wave, EMS, and vibration functions. During treatment, the EMS function delivers a gentle sensation of beating and kneading. The alternating frequency delivers low, mid, and high currents that simulate the therapeutic effects of acupuncture, offering rhythmic variations like lifting, staying, twisting, and turning. Compared to traditional scraping boards, this electric scraping device provides a significantly more comfortable skincare experience. After treatment, the skin only shows a temporary light flush, successfully preventing the severe blood congestion or potential tissue injury associated with traditional scraping.
