Botox in masseters also helps with nighttime teeth grinding and daily clenching, both practices which create a more square and larger jawline. This treatment involves 20 units of Botox injected in each masseter, the average amount needed for desired results. To maintain results it is suggested that the client repeats this treatment every 6 months, although in extreme cases additional treatments may be required for optimal results.
Injections can also lift your jawline and transform the appearance of people with receding chins. A hyperactive mentalis muscle contributes to a weakened and blunted-looking chin, and Injection acts on nerves to relax muscles and prevent them from contracting.
