Radar line carving is a kind of ultrasonic wave with good penetrating power, which is divided into medical equipment and beauty equipment. The high-strength positioning of the radar line for beauty use focuses on the skin 1.6-4.5mm mm (fascia layer), and simultaneously emits 600 -1200 rounds of ultrasonic nanowaves generate high-frequency friction between each other when focusing, stimulating thousands of thermal condensation points, and instantaneously produce 60-75 degrees of high temperature. Thermal stimulation caused by radar line carving will cause fascial cells There are three stages: 1. Cellular thermal damage; 2. Aggregation of self-energy repair; 3. Generation of new cells.
