Botox for Masseter (Square Jaw) Reduction
The masseter muscles in the jaw are the chewing muscles that allow for extreme pressure. They also help define the jawline, creating a wider or square appearance when they are over-exaggerated. For those with masseter hypertrophy, the jaw may be boxier than they may prefer, especially in women. The masseter muscles can also cause discomfort, impacting the tissues surrounding them. A reduction of the masseter muscle can alter the appearance of a square jaw and give relief, which can be achieved with Botox injections.
How Botox Works to Reduce Masseter Muscles
Most people think of Botox as a line or wrinkles reducer, but it has many other applications. The principles that help relax muscles to reduce forehead lines or brow furrows can also be used in other cosmetic and medical procedures. Botox works by blocking neurotransmitters to the targeted muscles, allowing them to relax.
For masseter muscles, Botox relaxes and controls the contractions, allowing them to weaken and shrink. This helps soften the jawline and can offer relief for those who has discomfort due to overly sized chewing muscles. Botox effects are not permanent; the injections need to be repeated about every six months to continue the effect. However, many that use Botox for masseter reduction see a permanent downsizing of the muscles after 2-3 treatments.
If you have a square jaw you want reduced or experience pain due to enlarged masseter muscles, contact a local facial plastic surgeon to discuss Botox treatments. In as little as a few weeks you can notice a reduction in your jaw width and experience relief from discomfort without the need for surgery or more invasive procedures.
