It might not be aging. It might not be filler. And it might not even be body fat.
It could actually be your masseter muscles.
The masseters are the large chewing muscles located at the sides of the jaw. Over time, these muscles can become enlarged from:
- Teeth grinding
- Jaw clenching
- Stress
- TMJ issues
- Excessive chewing/gum chewing
- Natural muscle hypertrophy
When the masseters become overdeveloped, they can make the lower face appear:
▪️ Wider
▪️ Heavier
▪️ More square-shaped
▪️ More tense or bulky
And a lot of people don’t even realize it’s happening.
Strategically placed Botox into the masseter muscles can help relax overactive muscle movement and gradually slim and soften the lower face over time.
Here’s why patients love Masseter Botox:
1. Slims and softens the jawline
Relaxing enlarged masseter muscles can help create a more tapered, contoured lower face appearance.
2. Helps create a more V-shaped facial appearance
Many patients notice the face appears slimmer and more balanced as the muscle bulk decreases.
3. Reduces jaw clenching
One of the biggest functional benefits 👏 Patients who constantly clench their jaw often experience major relief.
4. Helps teeth grinding (bruxism)
Masseter Botox may help reduce excessive grinding, especially during sleep.
5. Can improve TMJ-related discomfort
Some patients experience improvement in jaw tension, soreness, and tightness associated with TMJ symptoms.
6. Reduces facial tension
Overactive jaw muscles can create a constantly tense feeling in the face. Relaxing the muscle can help patients feel more comfortable overall.
7. Helps decrease tension headaches
For some patients, reducing jaw muscle overactivity may also help decrease headaches related to clenching and tension.
One of the biggest misconceptions is that facial shape changes are always caused by weight gain or aging… but muscle hypertrophy can completely change the appearance of the lower face over time!
