A wide or prominent jawline can influence the shape of the lower face, sometimes creating a heavier or more angular look. In some cases, this fullness is caused by an enlarged masseter muscle rather than bone structure.
Board-certified plastic surgeon Beverly Friedlander, MD, uses her surgical background and experience with facial anatomy to evaluate the jawline and identify where small adjustments can make your jaw look slimmer. She performs all facial balancing injections herself at her practice in Short Hills, New Jersey.
What Is Jaw Slimming?
Jaw slimming is a nonsurgical treatment that uses neuromodulators to relax the masseter muscle—the muscle at the back of the jaw responsible for clenching and chewing. When this muscle is overactive or naturally enlarged, it can cause the jawline to appear quite broad. By reducing this muscle activity over time, the jawline becomes more proportionate.
What Jaw Slimming Can Improve
Jaw slimming may help refine:
- A square or heavy lower face
- Jawline width caused by enlarged masseter muscles
- Facial imbalance between the lower and midface
- Tension from clenching or grinding
- The appearance of jaw heaviness in photos or profile views
Your Jaw Slimming Treatment
The session is simple and takes only a few minutes. Dr. Bev identifies the areas of the masseter muscle that require treatment and uses small injections to reduce its activity. Because she performs every injection herself, placement is consistent and carefully controlled.
You can return to your routine right away. Some temporary tightness or mild soreness may occur, especially if you clench at night, but this resolves without interrupting normal activity.
When Will You See Results?
As the masseter relaxes, the jawline gradually starts to look slimmer. Early changes begin to show within a few weeks, with full improvement developing over two to three months. This timing reflects how the muscle naturally softens and reduces in bulk.
Results typically last several months. Regular visits help maintain the shape while allowing Dr. Bev to fine-tune dosing based on your goals.
How Long Results Last
Neuromodulator effects last about three to four months, but the structural slimming may last longer as the muscle adapts to reduced activity. Because jaw slimming targets the masseter muscles, repeated treatments can gradually reduce muscle bulk over time, allowing results to appear more refined and longer-lasting with consistency.
A consistent treatment schedule will help you maintain your newly balanced lower face while preventing the muscle from regaining its previous prominence.
