Will A Masseter Injection Address An Asymmetrical Jawline?

By: Beauty Coordinators


Have you ever looked in the mirror and thought there is just something not quite right about the shape of your face, but you can’t quite figure out what it is? You may be surprised to learn that the jawline plays an incredibly significant role in the overall composition of your face. For example, an overly pronounced jaw can give women an unflattering, more masculine, square-shaped look. Another common problem for both men and women is an asymmetrical jawline. The expert team of licensed medical aestheticians at Body+Beauty Lab is proud to offer masseter injection with BOTOX® as a solution for men and women seeking jawline slimming in Philadelphia, PA.

What causes an asymmetrical jawline?

There are countless reasons that patients may have a slightly asymmetric jawline, crooked smile, or overall face shape. These can include genetics, sagging jowls, the aging process, injury, and trauma. However, one of the underlying causes of an asymmetric or particularly square face is an enlarged masseter muscle. The masseter muscle is a large, triangular, or parallelogram-shaped muscle that runs from the cheek down the outside of the jawline and is present on both sides of the face. Chewing is one of the major functions of the masseter muscle.

Why does the masseter become enlarged?

Enlargement of the masseter muscle, formally known as masseter hypertrophy, can have a number of causes, including:

  • Genetics/heredity
  • Race/ethnicity
  • Overuse
  • Clenching/grinding your teeth

In many patients, masseter hypertrophy is simply a natural condition and is bilateral. However, some men and women begin to notice that one side of their jawline has become more prominent over time. Masseter asymmetry often occurs when patients habitually chew only on one side of their mouth and/or when dental problems force the use of one side over the other.

How can you use BOTOX for jawline slimming?

Most people are familiar with BOTOX, an injectable neurotoxin that is commonly used to smooth out dynamic lines on the forehead, Crow’s feet, and other areas. However, BOTOX actually has a variety of applications beyond that. In fact, you can even use BOTOX to make your face symmetrical and slim the jawline!

During a Philadelphia, PA masseter BOTOX injection at Body+Beauty Lab, your certified and experienced provider will thoroughly evaluate your face, ask you to smile and make other expressions, and mark the treatment areas. There are typically 3-5 masseter BOTOX injection points on each side, but this can vary depending on the severity of the hypertrophy, the level of asymmetry, and other factors. Following BOTOX injection, patients are able to return to their daily routines with virtually no downtime. However, the results of the treatment will take about 7-10 days for the BOTOX to begin working, and the results will continue to develop over the next several weeks as the masseter muscle begins to atrophy and relax.

How long does masseter BOTOX last?

The results can vary from person to person, but most patients are able to enjoy their BOTOX jawline slimming for about 3-6 months before a repeat injection is needed. In many cases, patients are able to stretch out the length of time between injections after the first several treatments.

Does masseter BOTOX injection hurt?

Fortunately, most patients tolerate BOTOX masseter injection well without the need for anesthetics. Our caring team is dedicated to making each patient’s experience as comfortable and enjoyable as possible, however, and will apply a topical numbing cream prior to treatment.

Does BOTOX help sagging jowls?

Unfortunately, a masseter BOTOX injection is not an effective tool for correcting sagging jowls or excess fat under the chin. In fact, it can actually make the problem worse in some cases. If sagging jowls, excess fat, or drooping skin are your primary concerns, our knowledgeable providers can discuss alternate treatments that may be more appropriate for you, including nonsurgical jawline contouring with KYBELLA®. In addition, injectable dermal fillers can also be used to address lost facial volume and achieve greater symmetry overall.
