Because thread sculpting is not a surgical procedure, the patient is not so worried and scared psychologically, plus the trauma is small and the recovery is fast, so it is “favored” by the patient. However, there are a lot of people who are struggling with: why can thread sculpture only last 1~2 years? Wire sculpture can only last 1-2 years, mainly related to these three aspects: a. Wire wire Wire sculpture is the use of human absorbable medical wire, injected into the skin below the dermis or subcutaneous, according to the desired direction to create skin tension, not only has a direct lifting effect, but also improve the quality of the skin, so that the skin to restore a youthful state. The commonly used thread is the PPDO surgical thread. What are its characteristics? 1.Before 8~12 weeks of PPDO thread implantation, the degradation is slow, no obvious decomposition performance, and the inflammation reaction is slight. 2.After 8~12 weeks, the degradation will be accelerated and gradually destroyed into fragments, showing a slight chronic foreign body reaction, but there is no tissue necrosis and obvious granulation tissue proliferation, showing good histocompatibility, and finally decomposed into carbon dioxide and water in 24 weeks, and safely discharged out of the body without any residue. In other words: PPDO surgical threads can be absorbed and metabolized in 6~8 months. After the thread is absorbed away, the effect of stimulating collagen still exists, and the effect afterwards is mainly maintained by collagen. Generally can maintain about 1 year, the specific time varies from person to person. Second, secondary fixation The lifting effect of wire sculpture mainly comes from two aspects: 1. With serrated wire implanted into the deeper superficial fascial layer of the skin, many small barbs on its surface can well grasp the skin and play a lifting effect on the overall facial contour to support, sculpt the contour and resist gravity. Generally 6~8 months can be absorbed and metabolized, and the lifting effect of the thread will disappear. 2.The threads buried under the skin, especially under the dermis, are commonly used as smooth threads. The more smooth threads are buried, the larger the amount of scarring and the formation of a scar network. As the body responds to it with an increase in collagen and the aggregation of eosinophils, the skin becomes tightened up. It is important to emphasize that the scar network is not permanent, it has a proliferation phase and a maturation phase. Usually, after 2 years of scar maturation, it will become thinner and softer, and the skin tightening effect will become weaker at this time. Through the above introduction, it is easy to conclude that any mechanical fixation of the lifting effect is temporary. Since there is no secondary fixation of thread sculpture, relying only on the lifting of the wire and the role of the scar network, the maintenance time is generally not more than 2 years. Third, trauma We all know the truth: the more trauma, the better the skin tightening effect. Wire sculpture is minimally invasive, the incision is a needle eye of varying size, not stripping the skin, its own repair function is not long maintenance, is also one of the reasons why wire sculpture maintenance time is not long. Some candidates will say: we can bury more threads to increase the trauma ah? Can we do that? Generally speaking, for a moderately saggy face, to achieve a more desirable anti-aging effect, about 10 serrated lines and about 100 smooth lines are used. The more threads are buried, which means more foreign bodies are implanted into the tissue, which not only destroys the normal structure of the face and affects the expression, but also poses the risk of complications. Therefore, thread sculpting is generally used to improve the skin has a slight laxity of the candidates, and for moderate laxity and severe laxity of the candidates, not that you can not do thread sculpting, but the effect of thread sculpting is not so obvious, after all, a face is so big.
