When Will You See Results After BOTOX® in the Masseter?

By: Beauty Coordinators


A wide, square jawline is seen as a desirable feature in men, although that's not the case for most females. In fact, a slim jawline can give you the appearance of youth and femininity. But it's possible for your jawline to widen and enlarge over time as a result of repeatedly using the masseter muscle. Sometimes, the process of hypertrophy is caused by jaw clenching, teeth grinding (bruxism), or temporomandibular joint (TMJ) disorder.

Although BOTOX is most commonly known as a treatment for forehead lines and wrinkles around the eyes, it can also be effective to relax the masseter muscle. At Body+Beauty Lab in Philadelphia, PA, our skilled staff performs BOTOX injections in the masseter muscle to improve a wide jawline. Read on to learn more about how BOTOX injections work and how soon you can expect to see masseter BOTOX results.

What does the masseter muscle do?

The masseter muscle is a thick, flat muscle on each of your cheeks that that connects the lower jawbone to the cheekbone. It primarily serves to raise and lower your jaw, which controls chewing and speaking. Just like the way your muscles would expand when you work out at the gym, the masseter muscle bulks up and becomes stronger with repeated use over time. The result is hypertrophy, or enlargement of the masseter, which leads to the look of a square jawline that appears less slender.

How masseter BOTOX works

Masseter BOTOX injections are performed as an in-office treatment at Body+Beauty Lab. First, we will assess your jaw muscles and determine a customized treatment plan based on your goals. We will use a fine needle to place injections into precise areas of your jaw.

BOTOX is derived from a purified strain of the botulinum toxin, which temporarily prevents muscle movement once it is injected into your jaw. Only a skilled injector can determine the exact dose and location for the BOTOX. At Body+Beauty Lab, our injectors and aestheticians are highly trained and experienced in understanding the structure of the face in order to ensure that your results appear natural and symmetrical.

When does masseter BOTOX kick in?

BOTOX starts working right after your treatment, but it may take about a week before you begin to see your outcomes. You should see improvements continue over the next 3 – 6 months. Typically, you can expect to plan follow-up injections every few months in order to keep your jaw relaxed, which helps to shrink the masseter muscle so your jawline becomes slimmer over time.
