Face-lifting needle is a face-lifting method for masseter hypertrophy. Generally, it can last for about 6- 12 months at a time, and the duration varies according to the patient's physique and postoperative nursing. How often do you have a face-lifting needle? You can inject it when the face-lifting effect is about to disappear, or you can inject it two or three times in a row, with an interval of about 3 months, so that the face-lifting effect can be basically stable.
