No, face-lifting needle (botulinum toxin) injects botulinum toxin into hypertrophy muscles, so that the muscles there relax and atrophy, and the activity of masseter muscles decreases and atrophy becomes smaller. The face-lifting principle of botulinum toxin is that it can block nerve impulses of nerves and muscles, paralyze developed muscles to make them contract, and use paralyzed muscles to make originally hypertrophy muscles contract.
