Face-lifting needle is actually Botox. After injection, it can effectively block the nerves at the masseter muscle, make the masseter muscle atrophy, and thus achieve the purpose of face-lifting. But this nerve block is effective. With the passage of time, after the function of Botox disappears, the nerve at the masseter muscle will no longer be blocked. However, as long as we eat with our mouths open, we use the masseter muscle every day. The more we chew, the more developed the masseter muscles will become.
In fact, this truth is the same as going to the gym. If we lift iron every day, the muscles on our arms will naturally develop slowly. And you don't have to go to the gym every day, but you eat it every day.
So under normal circumstances, the effect of face-lifting needle can only last for about half a year. But after the failure, the masseter muscle will never become larger than before the injection, but will return to normal. You can inject it again after failure, and it will still work quickly ~
If you want to keep the effect of face-lifting needle longer. Pay attention to eat less hard and chewy food after injection. For example, chewing gum, melon seeds and beef tendon are too expensive, so eat less if you can.
