The ultrasonic scalpel uses advanced ultrasonic energy to focus highly and penetrate deeply. It focuses the ultrasonic wave at a single point to produce high energy, which acts on the muscle aponeurosis system to shrink the SMAS layer and produce the pulling effect. Radiofrequency is a non-invasive treatment. It is one of the safe and effective cosmetic wrinkle removal methods at present. The principle is that the RF wave penetrates the barrier of epidermal basal melanocytes, heats the collagen fibers in the true and cortex to 55 ℃ – 65 ℃, shrinks the collagen fibers, and tightens the loose skin wrinkles, so as to achieve the purpose of beauty and wrinkle removal. The two are applicable to different parts. Ultrasonic scalpel is mainly used for the face, and RF is used for the face, neck and various parts of the body. The safety and effect are different. The ultrasonic knife is easy to cause deep damage and other side effects due to high temperature, and RF has no side effects.
The principle of ultrasonic scalpel and radio frequency is to promote the synthesis of collagen through thermal stimulation. The difference is that the ultrasonic scalpel vertically heats the fascia layer through the point, and then the thermal effect diffuses around the point and gradually decreases, just like the ripple when a stone splashes into the water; RF is gradually heated from the epidermis to the inside, and the effect decreases slowly from the outside to the inside.
The ultrasonic scalpel can reach the skin layer that the general RF can not act on, but the coverage area is worse than that of RF. The more common radiofrequency treatments are thermomaggie, dark blue radiofrequency and thermolati. In terms of treatment effect, the lifting effect of ultrasonic knife is better, while the tightening effect of RF is better.
In terms of treatment comfort, ultrasonic scalpel is better than hot Maggie. Although it stimulates collagen synthesis through thermal effect, the temperature of hot Maggie is delivered from outside to inside, and the pain nerve skin is all over the skin epidermis, so the pain is stronger; The ultrasonic scalpel is heated vertically to a deeper layer of the skin, so there is usually a certain swelling after the operation, which can be reduced in about 10 days, while thermomaggie usually does not have swelling.
With the development of science and technology, radio frequency updates the hot lati plus, which combines the advantages of ultrasonic knife and hot Maggie. It can reach all skin cortex through frequency modulation and organically combine firmness and improvement. Moreover, the comfort is also greatly improved. Through the adjustment of power, you can choose to be painless for many times and have obvious heat feeling, but the effect is 1-2 times.
