In fact, the action level of thread sculpture and ultrasonic knife close to the dermis and subcutaneous superficial layer, the function of duplication, focus and different. Why do you say so? First of all, let’s talk about the ultrasonic knife: ultrasonic knife: is through the HIFU aggregation principle, the energy gathered in the SMAS layer (fascia layer), stimulate the SMAS fascia layer collagen proliferation and reorganization, to build a new collagen fiber network, in a non-invasive way, to achieve the effect of tightening and lifting, and to restore the elasticity of the skin and the vitality of youth. Most people can see the effects of tissue tightening, skin tightening, improved skin texture, and wrinkle reduction in a short period of time, while better results appear after 3 months of treatment as skin tissues need time to produce new collagen. Next, talk about Thread Sculpting: Thread Sculpting: The use of human body absorbable medical threads, such as: smooth threads, spiral threads, twine threads, liquid filler threads, serrated threads, double-ended threads, etc., which are injected below the dermis of the skin or subcutaneously to create tension in the skin in the desired direction. Not only does it have a direct lifting effect, but it also improves the quality of the skin at the same time, restoring the skin to its youthful state. Through the above introduction, it is not difficult for us to draw this conclusion: 1, the focus makes a difference Ultrasonic knife: to the overall tightening of the skin. Line carving: favors directed lifting. 2, the maintenance time is different ultrasonic knife: 1-2 years or so line carving: 1 year or so 3, different for the crowd ultrasonic knife: the static effect of small fine lines is good. But expression lines, decree lines, puppet lines, facial depression are powerless. Line carving: suitable for mildly flaccid candidates, generally around 30 years old. Some candidates will ask: Since the focus of thread sculpture and ultrasonic knife are different, can I do ultrasonic knife again after doing thread sculpture? It has been clinically found that doing ultrasonic scalpel treatment after thread sculpting can easily cause severe burns due to the higher heat absorption rate of the threads than the surrounding tissues. So is it feasible to do it the other way around? Candidates who have undergone ultrasonic scalpel, and then do thread sculpture lifting, can obviously feel the hardening of the tissue texture, difficult to enter the needle, candidates increased pain, the treatment effect is weaker than the non-ultrasonic scalpel treatment of the candidates. Suggestion: Candidates who have had thread lifting treatment are not recommended to undergo ultrasonic knife treatment within half a year, and it is better to adopt ultrasonic knife treatment after one year. If you want to use ultrasonic knife treatment after six months, it is recommended to judge the absorption of the line, can not judge the first from the smallest energy trial, do not directly use the normal standard.
