Masseter Botox Korea (face slimming)
Masseter Botox Korea (Face Slimming)
Masseter Botox is one of the most popular non-surgical treatments in Korea for achieving a slimmer, more defined jawline (V-line). In clinics across Seoul, this treatment is widely used for both cosmetic face slimming and medical relief (jaw tension, teeth grinding).
What Is Masseter Botox?
Masseter Botox is a procedure where botulinum toxin is injected into the masseter muscles (the chewing muscles at the sides of the jaw).
Purpose:
- Reduce muscle size
- Slim the lower face
- Soften a square jawline
It is a non-surgical, quick treatment that reshapes the face without altering bone or fat.
How Does It Slim the Face?
Masseter Botox works through a gradual process:
- Relaxes the jaw muscle
- Reduces clenching strength
- Muscle shrinks over time (atrophy)
- Jawline becomes slimmer and softer
This means results are progressive, not instant.
Key Benefits
Masseter Botox offers both aesthetic and functional benefits:
- Slimmer, more V-line face shape
- Softer and less square jawline
- Improved facial balance
- Relief from jaw clenching (bruxism)
- Reduction in jaw tension or TMJ symptoms
Treatment Process
A typical session in Seoul is very quick:
- Consultation and jaw assessment
- Marking injection points
- Botox injection into both sides of jaw
- Procedure time: 10–30 minutes
The injections are usually done at 2–3 points per side.
Pain and Downtime
- Mild discomfort (quick injections)
- Slight swelling or soreness for 1–2 days
- No major downtime
Most patients return to normal activities immediately.
When Will You See Results?
Masseter Botox takes longer than regular Botox.
- Initial effect: 2–3 weeks
- Visible slimming: 4–6 weeks
- Full results: up to 6–8 weeks
This is because the muscle gradually shrinks over time.
How Long Do Results Last?
- Average duration: 4–6 months
- With repeated treatments, results may last longer
- Maintenance is usually needed 2–3 times per year
