“There is no comparison between UltraSurgery and Thermage, as UltraSurgery is more suitable for lifting and Thermage is commonly used for skin tightening, they have different focuses. However, Thermage is now an obsolete technology. And ultrasonic knife? It is not yet certified by the CFDA in China. Here is a specific comparison of these two technologies to help you understand them more deeply: First of all, the ultrasonic knife and Thermage “anti-aging principle”. 1, ultrasonic knife ultrasonic knife is a high-intensity ultrasonic energy deep conduction to the dermis layer of the skin, resulting in nearly 10,000 coagulation points, so that collagen, fibrous mediastinum to produce immediate contraction and stimulate a large number of collagen newborns to build a new collagen fibers network, thus improving the problem of skin laxity and sagging. 2, Thermage Thermage is the use of electric waves to make the probe role of the skin, conduct radio frequency energy, first heating the epidermis, and then heating the dermis, equivalent to a piece of meat in a microwave oven to heat, activate the skin collagen and fibers, reconstructing collagen scaffolding, so as to achieve skin tightening, reduce the effect of wrinkles. Secondly, the difference between ultrasonic knife and Thermage is: 1, the role of the depth of different Ultrasonic knife can be 4.5mm probe directly to the skin deep muscle tendon layer; and Thermage less than 3.0mm, the deepest up to the dermis. In comparison, the ultrasonic knife role of the deeper level. 2, the treatment effect is different ultrasonic knife focuses on skin lifting, and Thermage focuses on tightening the skin. 3, postoperative comfort is different Preoperative surface anesthesia is required, the use of ultrasonic knife, some people will have a brief allergic phenomenon and redness. In addition, because of the need to promote the apoptosis of old cells, under the premise of standardized operation, there will be a slight swelling and pain when using it. Thermage does not use any anesthesia, there will be a slight redness in the treatment area, which will disappear after a few hours. A few people will have a slight swelling after the treatment, which usually subsides in 3-5 days. In terms of comfort, Thermage is slightly better than ultrasonic knife. 4, precision is different The area of action of Thermage is larger, that is because Thermage does not have a focusing function. Although the ultrasonic knife is focused sound waves hit in a point, but the ultrasonic knife is to take the precise route. 5, the treatment temperature is different ultrasonic knife on the skin heating can reach 65-70 ℃, can promote collagen denaturation; and heat Marji on the skin heating temperature is 40-55 ℃, can stimulate the production of new collagen. In terms of operating temperature, ultrasonic knife is warmer than Thermage. One last thing: for those who want to lift and tighten their facial skin through ultrasonic scalpel or Thermage, you can consider thread sculpture if you are around 30 years old, and you can consider surgical face lifting surgery if you are around 40 years old and above, so that the results will be more accurate after the surgery.
