The professional name of face-lifting needle is BOTOX, which is a biopharmaceutical 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. The current dose is only 1% of its maximum safe dose, so it is very safe.

Face-lifting by injection does not mean that the whole face is thin after one injection. It only acts on the muscles innervated by nerves in the hit area, and has no effect on other parts. In order to achieve the ideal injection effect, it is necessary to inject muscle according to the anatomical basis, coordinate and tighten some unreasonable muscle tissues, and make the mandible realize a delicate bone feeling curve. If you want to delay the recovery of masseter muscle, you should eat less hard and tough food and avoid frequent chewing exercises, such as chewing gum and biting melon seeds.

The effect of botulinum toxin face-lifting needle injection 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, after 3-6 months, it needs to be injected again to maintain the effect.
