Face-lifting needle is a botulinum toxin and a muscle relaxant. After injecting the muscle, the muscle can't move, and then it will shrink. At normal dosage, it is safe and harmless to the body. However, if an unprofessional doctor injects a face-lifting needle, it will have side effects once it is improperly operated. Improper operation of face-lifting needle injection will lead to postoperative facial stiffness and unnatural smile. Improper injection dose can also cause facial asymmetry. Too many face-lifting needles will lead to muscle relaxation and atrophy, reduce masseter activity, and affect eating. I suggest you let nature take its course. If you really want to get a face-lifting needle, I suggest you choose a regular hospital to find a professional doctor.
