Masseter BOTOX is an injectable neurotoxin treatment that relaxes the masseter, the large muscle on each side of the jaw responsible for chewing, to slim the lower face and create a more refined facial contour. It also relieves tension-related symptoms, such as jaw clenching, teeth grinding, and TMJ-related discomfort.
For patients who want a slimmer jawline without surgery, it’s a quick, nonsurgical option with no required downtime.
How Does Masseter BOTOX Work?
The masseter muscle sits along the sides of the jaw and, in some patients, is naturally larger due to genetics or becomes enlarged from chronic clenching and grinding. When injected with BOTOX, the muscle gradually relaxes and, over time, becomes smaller. The result is a slimmer, more oval lower facial contour that looks natural, not altered.
At Advanced Skin Lounge, your injector carefully evaluates your facial anatomy and muscle activity before treatment to ensure precise, balanced results tailored to your goals.

What Are the Benefits of Masseter BOTOX?
For patients who want a more refined facial profile without surgery, this treatment delivers results that are both precise and natural-looking:
- Slims and contours the lower face for a more refined profile
- Creates a softer, more oval facial shape that balances your features
- Delivers natural-looking results that complement your facial structure
- Requires no downtime—just a quick, in-office treatment
If you want a more defined, balanced facial profile without surgery, masseter BOTOX can help you achieve your goals.
What Should You Expect During Treatment?
The procedure is straightforward and typically takes less than 15 minutes. Your injector uses a fine needle to administer small, precise injections into the masseter muscle on each side of the jaw. Most patients describe the sensation as a light pinch.
You can return to your normal activities immediately; side effects are rare. We recommend avoiding strenuous exercise and refraining from rubbing the area for a few hours post-treatment.
How Long Do Results Last?
Masseter BOTOX results typically last 4 to 6 months. With consistent treatments, many patients notice longer-lasting contouring effects as the masseter gradually becomes less active over time.
Our team will help you establish a maintenance schedule that fits your goals and keeps your results looking their best.
