Before the face-lifting needle, the doctor should dilute the botulinum toxin, which is usually 100 unit, mix 3-4ml of normal saline and inject it at multiple points, and the recommended amount for each point is 0.25ml.

Botulinum toxin is a bacterial endotoxin secreted by lethal botulinum toxin, a toxic protein secreted by botulinum toxin in the process of reproduction, and has strong neurotoxicity.

Extended data:

Botulinum toxin is a neurotoxin, which can block the nerve impulse between nerve and muscle, make the small muscles of the face unable to contract, and at the same time, the skin is in a state of static and non-contraction, thus achieving the effect of eliminating facial dynamic wrinkles and face-lifting. However, botulinum toxin should not be injected frequently, and it should be injected at least once every 6 months.

It is also worth noting that pregnant women, lactating women, patients with myasthenia gravis, allergic people, patients with ptosis and patients with visceral diseases such as heart, liver, lung and kidney cannot use botulinum toxin to remove wrinkles.
