What Botox for Facial Slimming Is
Botox for facial slimming typically targets the masseter muscles — the chewing muscles on the sides of your lower face. When these muscles are overactive or bulky, they can make the face look wide or square. Injecting Botox into those muscles relaxes them, which over time can create a softer, slimmer lower-face appearance.
This is a non-surgical contouring option that works gradually and subtly.
How It Works
- Targeted injections: A provider places Botox into specific points in each masseter muscle.
- Muscle relaxation: The toxin reduces the strength of the muscle contractions.
- Gradual slimming effect: As the muscle activity lessens, the muscle can shrink slightly, softening the jawline contour.
This does not change bone structure — it reshapes the face by reducing muscle prominence.
What to Expect
Consultation
Before treatment, a proper consultation should include:
- A look at your facial anatomy and muscle function
- Discussion of your slimming goals
- Explanation of how many units will be used and why
- Time for you to ask questions
The Procedure
- Quick: Usually takes about 10–20 minutes
- Comfortable: Small injections into the masseter area
- Minimal downtime: Most people can resume daily activities immediately
Results & Timing
- Initial effect: Some muscle softening within a few days
- Visible contour change: Typically over several weeks
- Full effect: Around 6–8 weeks
- Duration: Effects usually last about 3–6 months depending on muscle strength and dosing
Maintenance treatments help sustain the slimmer look.
Benefits
✔ Softer, narrower lower-face contour
✔ Non-surgical, minimally invasive
✔ Quick procedure with little downtime
✔ Natural-looking results when placed carefully
Who It’s Best For
Botox for facial slimming is ideal if you:
- Have a wide or square lower face largely due to masseter muscle bulk
- Prefer a non-surgical contouring option
- Want a gradual, natural change in face shape
- Are willing to return for periodic touch-ups to maintain the effect
If your jaw shape is primarily due to bone structure, surgical options are more effective for changing bone-related width.
Aftercare Tips
To support good results:
✅ Avoid touching or pressing the treated area for about
24 hours
✅ Stay upright for a few hours after injections
✅ Avoid intense exercise or heat (like saunas/steam) on the day of treatment
✅ Follow any aftercare instructions your provider gives
