You can see the effect after 3-5 days of face-lifting needle injection, because the drugs injected after face-lifting needle injection are very safe and will be metabolized in the body and excreted. So if you want a better effect, you still need another injection. Face-lifting acupuncture can block nerve impulses of nerves and muscles through drugs, paralyze over-developed muscles and make them contract. It uses paralyzed muscles to achieve the purpose of "prohibiting atrophy" and make the originally hypertrophy muscles atrophy. Face-lifting acupuncture is mainly aimed at the symptoms of facial masseter muscle hypertrophy. The masseter muscle in the cheek, when the hypertrophy masseter muscle contracts, also achieved the effect of face-lifting. Simply put, with paralyzed muscles, you can't exercise, and eventually your muscles will shrink. Make your face look smaller.
