Jaw Reduction vs Masseter Botox Korea
Jaw Reduction vs Masseter Botox Korea
Jaw reduction surgery and masseter Botox both slim the lower face, but they target different anatomical causes of width. One reshapes the jawbone, while the other reduces the jaw muscle size.
What is Jaw Reduction Surgery?
Jaw reduction surgery (mandibular angle reduction) reshapes the bone to create a slimmer jawline.
- Involves cutting and smoothing the jaw angle
- Permanently reduces lower face width
- Creates a more tapered or V-line appearance
- Requires general anesthesia and recovery
- Often combined with chin contouring
This is the most effective option when jaw width is caused by bone structure.
What is Masseter Botox?
Masseter Botox reduces the size of the jaw muscles to slim the face non-surgically.
- Injects botulinum toxin into the masseter muscles
- Gradually reduces muscle bulk over weeks
- No surgery or downtime required
- Temporary results (typically 3–6 months)
- Can also help with teeth grinding (bruxism)
This works best when the jaw looks wide due to muscle hypertrophy, not bone.
Key Differences Between Jaw Reduction and Masseter Botox
- Primary target
Jaw reduction: bone (mandible)
Botox: muscle (masseter) - Level of change
Jaw reduction: dramatic and structural
Botox: subtle to moderate - Invasiveness
Jaw reduction: major surgery
Botox: non-invasive injection - Longevity
Jaw reduction: permanent
Botox: temporary - Recovery
Jaw reduction: significant downtime
Botox: minimal to none - Best candidates
Jaw reduction: wide jaw due to bone
Botox: enlarged jaw muscles
Price Comparison (Korea)
- Jaw Reduction Surgery: ~₩8,000,000 – 20,000,000+
- Masseter Botox: ~₩50,000 – 300,000 per session
Botox is more affordable upfront but requires maintenance treatments.
Which is Better?
Jaw reduction surgery may be better if
- Your jaw is wide due to bone structure
- You want a permanent and significant change
- You are aiming for a defined V-line
- You are comfortable with surgery and recovery
Masseter Botox may be better if
- Your jaw width is caused by muscle bulk
- You want a non-surgical option
- You prefer gradual, subtle slimming
- You want minimal downtime
Final Thoughts
Jaw reduction and masseter Botox are not interchangeable—they address different causes of a wide jaw. Surgery reshapes bone for permanent transformation, while Botox reduces muscle size temporarily. The best choice depends on whether your jawline is wide due to bone or muscle, and how dramatic and long-lasting you want the result to be.
