Judging from the effect of face-lifting needle, we can know that face-lifting needle should be re-examined after 2 weeks. Botox is reversible after facial plastic surgery, which means that after 3 to 6 months, it needs to be injected again to maintain the effect. This is just a general pattern. In particular, the actual number of shots depends on personal circumstances. Different people face different initial conditions, and the care of face-lifting after injection is also different. So in real life, the number of bullets cannot be generalized.
