Hifu advantages:   1. instead of the traditional surgical face lift with a non-invasive technique.   2. tighten sagging skin, improve sagging and other signs of aging.   3. with a special transmitter, transmission from the skin surface conduction of high-energy focused ultrasound to the smas layer.   4. smas contraction : collagen remodeling , elastine fiber contraction.   5. in the skin layer to produce the specified target multiple temperatures above 65-70 degrees in short time or above sonic focus high energy, forming?heat cure? area, the focus cells are solidified, then ablation, fascia speedy improvement, to achieve cosmetic wrinkle effect.   6. non-invasive, no time to rest after surgery, ultrasound without injections, no surgery, no trace wrinkle skin rejuvenation.
