? This machine combines RF with 40KHz ultrasound cavitation. The 40KHz cavitation is emitted to vibrate fat cells at top speed to promote cells motivation so as to reduce fat. ? The vacuum RF can focus the RF energy on a specific area to reduce fat, accelerate metabolism, relieve muscle fatigue, and tighten the skin by delivering thermal energy. ? The vacuum can also accelerate metabolism and relieve muscle tension by suction massage. ?SPECIFICATION?
