Face-lifting needle works quickly, but it doesn't last long. At present, there is only one kind of botulinum toxin in face-lifting needle, and the general effect can only last for 6 ~ 12 months without side effects. Generally, the effect will be stable after 3 or 4 times. Face-lifting needles will not leave scars like traditional face-lifting needles, but they may rebound, which varies from person to person. After operation, we should pay attention to rest and avoid violent facial movements in a suitable time, which can reduce the occurrence of rebound.
