It's actually quite scary. My colleague has done it, that is to say, the face-lifting needle is long-term, twice a year, and it can only last for a period of time, which is more expensive. No one in my unit has done it, but my colleague said it was very painful. I just injected it with a small needle, and my face was covered with red pinholes, which made me feel scared. Have you ever kissed? Can you tell me about your experience? I'm just afraid of insecurity, and I'm in my twenties. I'm afraid my face is allergic, and it's not worth the loss. Face-lifting needle face-lifting is essentially to treat masseter hypertrophy with botulinum toxin injection. It is found that it is difficult to grasp the amount and depth of muscle resection in mandibular angle surgery, which not only leads to unsatisfactory results, but also increases the chances of bleeding, hematoma and infection, leading to serious complications such as asymmetry on both sides of the face, clenched teeth and long-term muscle spasm. 1994, Smyth et al reported the experience of treating bilateral masseter hypertrophy with botulinum toxin A, which was considered as a revolutionary new method. Botulinum toxin injection can reduce occlusal atrophy by denervation and make the treatment more thorough.
