The answer is definitely: wrong. The face slimming injection is actually botulinum toxin, the effect of botulinum toxin is to paralyze the nerve, like a knife to cut off the conduction of neuromuscular electrical signals, the muscle is in a state of paralysis after the loss of this movement, the muscle appears atrophy. We commonly see patients who are bedridden for a long time, their legs look very thin, the same reason, our muscles do not move, his muscles slowly atrophied, the volume has become smaller, this is a normal physiological changes. Botox only works for six months, about six months, the neuromuscles are slowly recovering, just like a light bulb lights up again after the wire is on. If you want to keep the effect, you have to keep playing. Some people say that Botox can keep the effect permanently with three injections, which is just a statement. Very few people, after many face slimming injections, because of the habit of not biting things hard, the muscles can not work, so that even if no more face slimming injections, the muscles are no longer slowly growing. Of course there is another situation, there are some informal institutions in the botulinum toxin mixed with hormonal drugs to be able to make the time longer, but this way is not desirable. Therefore, playing three injections on the shape of the statement is not accurate, most people still need to regularly play slimming injection, in order to achieve the real purpose of thin face. Of course some people say that wrinkle injections will be more aging once they stop, from my own point of view, my forehead lines played also more than ten years, this situation I have not seen, I have not seen among the candidates I treated.
