Will BOTOX® in the Masseter Give Me an Asymmetric Smile?

By: Beauty Coordinators


The masseter muscle runs from the cheekbone down to the lower jaw of the face. This muscle is responsible for simple actions, like speaking and chewing. Working out the muscle too often, however, could lead to an enlargement of the masseter. This is why some people get a muscular or square-looking jawline.

If you are looking for a facial slimming procedure, allow the professionals at Body+Beauty Lab to help. We offer BOTOX injections in the masseter muscle to correct your jawline. While this treatment is not expected to give you an asymmetrical smile, patients should learn about common masseter BOTOX side effects and other details involved. Read below or schedule an in-person or online BOTOX consultation in Philadelphia, PA to learn more.

What causes an enlarged masseter muscle?

Normal jaw movement does not usually cause the enlargement of the masseter muscle. However, when you exercise the masseter muscle more than average through excess chewing or jaw clenching, it can appear more muscular. Since these behaviors are sometimes hard to notice, you may not realize what is happening before it is too late. The great news is that BOTOX injections are an effective way to relax the masseter muscle and cause it to shrink back down.

Relax the masseter muscle with BOTOX

BOTOX is a wrinkle relaxer that works by blocking certain signals from the nerves, causing the muscles to slow down movement. Most people consider wrinkle relaxers for cosmetic reasons, to reduce the appearance of fine lines and wrinkles. Body+Beauty Lab also offers BOTOX for facial slimming purposes. It limits the movement of the masseter muscle and prevents it from working so hard. As a result, you can achieve a natural-looking jawline that makes your features appear more proportional.

Benefits of treatment in Philadelphia, PA, include:

  • Reduce the width of the jawline

  • Improve asymmetry in the jaw

  • Create a more youthful face shape

Potential side effects of BOTOX

Injecting BOTOX in the masseter muscle requires an understanding of how the muscles work as well as in-depth knowledge of facial anatomy. If BOTOX is not placed correctly or is administered by an inexperienced professional, you are more likely to experience poor side effects. Rest assured that at Body+Beauty Lab, we have helped countless people achieve great results with minimal downtime and complications. Potential side effects of treatment include:

  • Soreness or redness at the injection site

  • Allergic reactions in individuals who are sensitive to BOTOX

  • Loss of muscle weakness or strength

  • Problems swallowing or speaking

Jawline or smile asymmetry may be one of the possible masseter BOTOX side effects. Generally, this condition is temporary and should not last for long. Patients who experience issues can contact our team for safe and effective tips for moving forward.
