It is convenient and effective to have a face-lifting needle, but some people have such a question: Now let's see how contemporary face-lifting experts answer it. Face-lifting acupuncture essentially treats masseter hypertrophy by injecting biological agents. Face-lifting needle injection is a very good face-lifting method, and generally there will be no sequelae and harm. Face-lifting needle has no operation, no trauma, no trace and no pain. Injection can achieve face-lifting effect, with soft face-lifting curve and natural effect. However, if the face-lifting needle is operated carelessly and the injection is unreasonable, there may be facial swelling, which is a doctor's technique and technical problem, so we must choose a regular hospital to inject face-lifting needle. Under normal circumstances, there may be slight swelling and temporary slight redness and swelling at the site where the face-lifting needle is injected, and there may be slight bruising locally, which will gradually disappear after a few days. If the face is still swollen after one month, it may be the quality problem of the face-lifting needle, improper operation during injection, or personal physical reasons. The swelling may disappear after a long time. The specific reason can only be known through hospital examination and injection with face-lifting needle. Contemporary face-lifting needle experts said that as long as the botulinum face-lifting needle is correctly operated, there will be no obvious facial swelling when using the face-lifting needle, and slight swelling is within the normal range. If the face swelling is serious after the face-lifting needle, it is usually caused by overdose. Therefore, as long as you choose a professional hospital to have a face-lifting needle, there will be no swelling, so you still have to choose a regular hospital to have a face-lifting needle.
