Advantages and Disadvantages of Ultrasonic Knife

The ultrasonic knife is a beauty technology based on the ultrasonic wave, which can release a high-intensity focused ultrasonic wave. By making use of the physical characteristics of ultrasound in biological tissue, such as directionality, penetration, and focalization, external energy ultrasound can penetrate normal tissue, which accurately focuses on the beauty treatment area in the body, and instantly produces 65 ~ 70 ℃ thermal coagulation nodes within 0.5s, making the tissue cells in the target area produce protein coagulation reaction immediately. Take the freezing point as the center to generate tension around, and immediately show the tightening and lifting effect.


The effect of an ultrasonic knife can usually last for 2 to 3 years. The cosmetic process of this method is simple, and there is no need to stay for a long time for observation after the operation; The energy position can be accurately adjusted to focus the energy at one point in a non-invasive way, and the surrounding tissue will not be affected because it is not in the focus. According to different skin types, wrinkle depths, and wrinkle areas, one or more of the most suitable probes can be selected for targeted wrinkle removal. The effect is very ideal. However, the ultrasonic knife has disadvantages: When high-energy sound waves reach the dermis, making the temperature of the dermis reach the high temperature of 65-70 degrees, fibroblasts are likely to be injured or even die. No matter how precise you control it, you can't just heat collagen without heating mother cells. Therefore, one of the causes of side effects is thermal damage to other cells and tissues. Another disadvantage of ultrasonic knives is that high temperatures will damage some fat cells, resulting in fat loss. For some people with more fat, it doesn't matter to lose some fat, but for others who don't have much fat, it will have side effects. Without the support of certain fat, the skin will not appear full.


Therefore, if beauty seekers want to do ultrasonic knife beauty, they must find a standardized medical beauty operation place with qualified doctors and standardized equipment. In some places, operators are only trained for several days, which has great risks and hazards. With a strong intelligent temperature guarantee, the effect appears immediately. The operating temperature is 65 ℃ - 70 ℃, which is the strong temperature of all non-invasive skin tightening instruments and the better temperature for the regeneration of collagen. Therefore: the lifting and tightening effect will appear immediately, and the energy will pass through the skin without heating the skin, so there is no need to worry about skin damage. With sound wave image positioning, extremely accurate "positioning index line" and automatic energy prompt, doctors can accurately control the operation depth and energy. The real-time development technology of ultrasonic knife can observe the fascia tissue up to 8mm deep at any time. In the process of operation, doctors use energy more skillfully to ensure small errors and safety.
