About two weeks to a month after injection of botulinum toxin, the face-lifting effect began to be seen. Some people may have obvious face-lifting effect within 1-2 weeks. If some people have no face-lifting effect for a period of time after injecting face-lifting needles, don't worry too much, because the effect of face-lifting on everyone may not start to show at the same time. Under normal circumstances, the best face-lifting effect can be basically achieved after three months, and the masseter muscle can be obviously contracted by about 30%.
Botox injection has such a good face-lifting effect, so is it permanent after it makes people face-lifting? When face-lifting is not once and for all, the face-lifting effect of Botox injection is not permanent. Usually, you can maintain a good face-lifting effect for about half a year. Therefore, in order to maintain the face-lifting effect for a long time, you generally need to take three face-lifting needles regularly, and then keep your face-lifting for one year. At the same time, if the movement of masseter muscle is reduced or alleviated, the good face-lifting effect can be maintained for a longer time. For example, those who eat less hard and have strong elasticity, such as chewing gum and melon seeds, can maintain the face-lifting effect to a certain extent.
The above is the knowledge about how long it takes to take effect after injection of botulinum toxin. I hope that everyone will go to a regular plastic surgery institution for injection to ensure safety and effectiveness, and at the same time do a good job in postoperative care!
