First of all, understand the anti-aging principle of ultrasonic knife. Ultrasonic knife is a focused ultrasound, the surface does not hurt the skin, to a certain depth of the subcutaneous or fascial layer in order to have a multi-point focus, so that the temperature of the point is up to 65 ~ 70 ℃ in the subcutaneous caused by mild scarring, the use of scarring itself contracture, to enhance the purpose of the facial tissues. The reason is: Collagen heating to 40 ~ 60 ℃ can have the effect of stimulating proliferation, 60 ~ 70 ℃ can be done to make collagen deformation, contraction. Ultrasonic knife using 1.5mm, 3.0mm, 4.5mm treatment head were focused on the superficial dermis, deep dermis, fascia layer, the limit of heating temperature can be up to 65 ~ 70 ℃, as long as the heating temperature and time regulation is very restrained, resulting in minor subcutaneous injuries, do not cause permanent trauma that is difficult to recover, can promote collagen proliferation and denaturation contraction, to achieve the removal of wrinkles, tighten the skin, The purpose of face lift. Secondly, can the skin condition be significantly improved after doing ultrasonic scalpel? There is no good or bad technology, it only depends on whether it is suitable for you. From the analysis of the principle of action of ultrasonic knife, it can stimulate the dermal layer of collagen newborn, so that the dermis layer thickening, fascia layer lifting, but also has a slight lipolysis effect. Generally speaking, the effect of ultrasonic knife treatment can be seen once, instantly can see the lifting effect brought by collagen contraction, and the follow-up in 2-3 months still have continuous improvement, lifting, firming, filling, wrinkle reduction. However, it has an age limit and can be considered around 30 and above, depending on the actual condition of the candidate’s face, and for candidates in their 40s it may be more suitable for a surgical type of face lift. Finally, in what problems can ultrasonic scalpel help? Ultrasonic knife using 3 treatment head, stimulate the dermis collagen newborn, so that the dermis layer thickening, fascia layer lifting, it can help you in these places: 1, tighten the forehead skin tissues, lifting the eyebrow and eye line; 2, reduce the “double chin”, improve the jawline; 3, improve the nasolabial folds, improve the decree lines; 4, tightening, lifting Facial tissues and skin; 5, reduce facial wrinkles, improve skin elasticity; However, at present, although the ultrasonic knife in the United States has been certified by the FDA, has not yet been certified by the Chinese CFDA. In theory, the same part of the long operation of ultrasonic knife, may cause stiff expression, zombie face, unevenness and other serious consequences, but also may damage the facial nerves, resulting in local bleeding or even leave scars.
