For people with a particularly thin face, the ultrasonic knife will take about 7 ~ 10 days to work. The ultrasonic knife can tighten and lift the skin in a short time without damaging the skin tissue of the epidermal layer.
The principle of ultrasonic scalpel is mainly to convert energy into heat in a short time through polymer energy, which directly acts on the skin fiber layer of the skin. After physical effects, it can start the self-healing function of the skin, regrow the cell tissue from the bottom of the skin, achieve the function of reactivation, and reactivate the necrotic cell particles, Make the skin more compact and elastic. The electric wave of the ultrasonic knife can directly focus on a unit point to generate high-energy heat. Usually, the temperature can reach 65 ° C to 70 ° C. Therefore, the local skin will have a slight burning and swelling feeling. It needs to be cold compress. After 48 hours, the burning feeling will gradually disappear, It will not damage the surrounding healthy skin tissue.
