Many beauty places, in order to eliminate people’s fears, call it biological wrinkle removal or genetic wrinkle removal. Because of its nerve blocking effect, it is very commonly used in neurology, ophthalmology, plastic and cosmetic surgery. The current dose used is only one percent of its maximum safe dose, so it is very safe. How does the face slimming injection work? How long does it last? Botulinum toxin bite within a week after the injection can be observed in the face gradually thinning to achieve the “thin face” effect. After two or three months, the effect of face slimming reaches its peak, and the bite muscle can be reduced by about 30% to 60%, and the effect can last for about six months to a year. If you delay the speed of recovery of the bite muscle, we must eat less hard, tough food, if appropriate to avoid frequent chewing movements (such as chewing gum, beef jerky, knocking melon seeds, etc.) can also be maintained for a longer period of time.
