Plastic surgery:
The principle of face-lifting needle is to block nerve impulses of nerves and muscles, relax over-contracted muscles and paralyze over-developed muscles. It uses paralyzed muscles to contract the originally hypertrophy muscles and achieve the effect of face-lifting. Face-lifting needles are usually injected at 1 ~ 2 injection points on each side, and the injection process takes about 20 minutes, so there is no need for anesthesia, and the injection trauma is small and the recovery is fast. Needle face-lifting is to inject a bioactive element (botulinum toxin A) into the masseter muscle, which can gradually contract the masseter muscle by inhibiting the transmission of acetylcholine transmitter at the neuromuscular junction, thus achieving the effect of face-lifting The injection is prepared by gene and biosynthesis, adding appropriate protective agent and freeze-dried powder.
