Ultrasonic scalpel focuses the safe ultrasonic energy, and after reaching the energy value, it quickly solidifies the subcutaneous SMAS layer at an accurate point. The whole face can form 8000- 10000 independent collagen freezing points for lifting, which can not only improve the contour of the face, but also produce divergent new collagen from these points, so that it can be lifted upward for several months after treatment, tightening the already relaxed skin. You will find that the relaxed Risolius is pulled back, even the skin between the eyebrows and eyes will be pulled up, the outline of the jaw will be clear and the pores will be narrowed. Ultrasonic scalpel has high energy and deep penetration, and the generated heat energy and collagen regeneration will consume too much water in the skin, so strengthening hydrating hydrotherapy can replenish extra water for the skin and regenerate collagen.
