The main component of face-lifting needle is botulinum toxin, which is a type A toxin secreted by botulinum in reproduction. Botulinum toxin can prevent muscle contraction, relax the masseter and make the face smaller. In addition, botulinum toxin can stretch the skin, remove wrinkles and reproduce youth.

Face-lifting needle injects botulinum toxin into masseter muscle, blocking the transmission of media between neuromuscular cells, causing muscle flaccid paralysis and atrophy, thus achieving the effect of reducing masseter muscle volume and face-lifting. Generally speaking, cosmetic surgery has no serious complications.

However, if the injection is excessive, there may be diplopia, unnatural expression and other adverse reactions, and even life-threatening. The dilution, injection site, injection opportunity and interval of each injection of botulinum toxin are very strict and must be operated by doctors with rich medical experience.
