Face-lifting needle, that is, botulinum toxin A injection, mainly acts on muscle tissue and is called face-lifting needle because it is often used to solve masseter hypertrophy. The professional name of face-lifting needle is botulinum toxin, which is a biological product and can be produced on a large scale through genetic engineering. Because of its nerve blocking effect, it is very commonly used in neurology, ophthalmology, plastic surgery and cosmetic surgery.

Face-lifting needle face-lifting is essentially to treat masseter hypertrophy with botulinum toxin injection. It is found that it is difficult to grasp muscles during mandibular angle surgery.

The amount and depth of muscle resection are not only unsatisfactory, but also easy to increase the chances of bleeding, hematoma and infection, resulting in asymmetry on both sides of the face and closed teeth.

And serious complications such as prolonged muscle spasm. In 1994, Smyth et al. reported the use of botulinum toxin type A.

The experience of treating bilateral masseter hypertrophy with botulinum toxin is considered as a revolutionary new method. Botulinum toxin injection can reduce occlusal atrophy by denervation and make the treatment more thorough.

The effect of face-lifting needle is not 100%. After several injections, a few people will produce antibodies to botulinum toxin, making future injections ineffective. Because of chewing habits, there will still be slight asymmetry on both sides after injection. A few people may not be sensitive to drugs, so the effect is not obvious, and they need to return to the clinic after 2 weeks. Botulinum toxin can be recovered after injection, that is to say, after 3 to 6 months, it needs to be injected again to maintain the effect.

1 1, Botox can be recovered after face-lifting (face-lifting needle), that is to say, it needs another injection after six months in theory to maintain the effect. Some people can keep it for a long time with 2-3 injections. If you want to delay the recovery of masseter muscle, you should eat less hard and tough food. But clinically, we found that some people don't need to inject again after 2-3 times to maintain the effect, which means that the influence of Botox on Chinese face is long-term. The reason is that during the curative effect of Botox, the human body cannot overuse the masticatory muscles. If we can get rid of the habit of overusing masticatory muscles, after the curative effect of Botox, the thinner masticatory muscles will not hypertrophy and proliferate again.

12. Don't stay up all night for one week after the injection, the efficacy will be reduced after getting angry.
