Application of HIFU Piezo Ceramic:
Ultrasonic focus ceramic (HIFU) is widely used in the beauty, weight loss medical industry and liposonix,ultra Shape.On behalf of the product is this year the rise of the ultrasonic knife, Liposonix slimming Instrument,Ultra Shape slimming instrument.
High Intensity Focused Ultrasound(HIFU)：
High Intensity Focused Ultrasound is a non-surgical, no downtime, in-office procedure for lifting and tightening sagging skin of the brows, cheeks, lower face (jowls), jawline and neck. Ultrasound technology is focused below the skin surface to firm and lift droopy tissues. Results are long lasting and occur gradually but dramatically over time.
