At the age of 32, you can use ultrasonic knife or thread sculpture to improve the “old look” of facial laxity. Which one is more effective? They both work on the SMAS fascia layer and maintain the effect for about the same amount of time, basically about 1 year, but not excluding individual differences, the difference lies in the focus of the technology. Thread sculpting focuses on lifting, while ultrasonic knife is more suitable for skin tightening. The beauty seekers may want to combine the two treatments for better results. This is determined by their “anti-aging principle”. First, let’s talk about thread sculpting. In simple terms, thread sculpting is the process of burying an absorbable medical thread (PPDO thread) into the facial skin and stretching it upwards to counteract gravity. This has 2 benefits: 1. The barbed threads buried in the superficial fascia layer can serve as a face lift and sculpt the contours. 2. The smoothing threads implanted in the dermis mainly serve to tighten the skin. 3.The buried threads will be absorbed in 6~8 months, when it will stimulate the collagen growth, and the effect afterwards will be mainly maintained by it. Next, let’s understand the ultrasonic knife. Ultrasonic knife is simply the use of ultrasonic waves in a certain depth of the subcutaneous or fascial layer to form a multi-point aggregation, so that the temperature of the point up to 60-70 ℃. When applied to the face, it has 2 effects: 1, immediate contraction of skin collagen and SMAS Immediately after the treatment, candidates can instantly see their skin condition has changed for the better. 2. Long-term reorganization of collagen after the thermal effect on the tissue. For the vast majority of candidates, the effect is most obvious 3-6 months after the ultrasonic knife treatment. This results in – achieving a tighter silhouette and smoothing out small static fine lines. Thus, it seems that it relies mainly on heating the subcutaneous fascial tissue to induce collagen production, and the later effects are mainly maintained by it. Finally, we came to a conclusion: 1, thread sculpting is more inclined to face lifting, while ultrasonic knife is suitable for skin tightening. 2, 4 months after the ultrasonic knife hit the best effect, wire sculpture instant effect is the best. 3, ultrasonic knife almost no recovery period, the 2nd day can makeup. There is a subtle wound with the buried thread, which disappears after about 7~10 days. 4, Thread sculpting and ultrasonic knife, as there is no peeling of the skin, allowing the skin tissue to biologically heal. Mechanical lifting alone, the effect will not be maintained for a long time. Therefore, candidates may wish to combine the two treatments, the effect will be better, but the same part can not be done at the same time.
