JAWLINE · ILLUSTRATED 3D RECOVERY
Masseter Botox (Jaw-Slimming Injections): before & after and recovery stages
Separate early changes during clenching from the slower change in jaw-angle muscle prominence.
Also called masseter injections · jaw reduction injections
SUMMARY
What this example shows
Clenching shows illustrative muscle prominence at the jaw angles. Reduced movement precedes the slower contour change. The example narrows soft tissue locally; it does not alter jawbone, remove fat or lift loose skin. Product, muscle anatomy and local indications vary.
STAGE BY STAGE
Masseter Botox (Jaw-Slimming Injections) recovery stages
Jaw-angle reference
Compare the relaxed face with the same clenching effort.
A broad jaw can reflect more than muscle; the model does not assess your anatomy.
Around 2 weeks: Movement before contour
The clenching bulge is smaller, with little resting contour change.
Muscle activity and visible lower-face volume are different outcomes.
Around 3 months: Later contour comparison
The example has less soft-tissue prominence at each jaw angle.
Randomized trials assessed volume or thickness around 12 weeks or day 90.
Around 6 months: Return varies
The model restores some clenching prominence and contour.
The illustrated return is not a study-derived recovery curve or treatment schedule.

INDIVIDUAL DIFFERENCES
How recovery can vary
Timing and response
The research concerns selected adults and specific products. Results, muscle balance and chewing function vary; local indications differ. This model cannot show bite force or diagnose the cause of jaw width.
Longer term
Muscle activity and size may return on different clocks. Bone, fat and loose skin are not treated by this illustrative muscle-volume change.
EVIDENCE NOTES
Sources and limitations
- JAAD · randomized trial: Masseter prominence study
A phase 2 trial assessed lower-face volume at day 90 in adults with marked bilateral muscle prominence. Industry affiliations are disclosed.
- Dermatologic Surgery · randomized trial: Masseter hypertrophy study
A product-specific trial found the largest muscle-thickness differences at 12 weeks. It does not establish a universal individual timeline.
- AAD: Botulinum toxin therapy: FAQs
Targeted muscle relaxation, preservation of other expressions and temporary injection reactions.
