At present, injecting chin-thinning needle is a good way to thin chin. But many beauty lovers are concerned about whether chin plastic's thin chin needle will rebound after injection. So will the botulinum toxin thin chin needle rebound? We listened to the introduction of Shijiazhuang Xingyuan plastic surgery experts. Experts say that the effect of injecting botulinum toxin is not permanent. Usually after three to six months, the therapeutic effect will gradually disappear. At this time, if you want to get the original curative effect, you must receive another injection. If you can return to your original state, or on impulse, or find that your face is thin, it will not look good. This shows that it has the characteristics of recovery and has not rebounded. So please feel free to inject. Botulinum toxin thin chin is essentially the treatment of masseter hypertrophy by botulinum toxin injection. Botulinum toxin injection can make the bite atrophy smaller and the treatment more thorough. Injection should be as slow as possible, and special treatment such as local massage is not needed after injection. Generally, normal chewing exercise can make the liquid medicine gradually spread in muscle tissue, and the effect can be observed after one month. Of course, the above guarantees that the surgical effect will not rebound, but for better surgical effect, the precautions before and after the operation must be completed step by step!
