Masseter Botox in Seoul | Jaw Slimming & Functional Relief at BAILOR Clinic
Introduction
Jawline contouring through Botulinum toxinโtype A injections—commonly known as “masseter Botox”—has become a top non-surgical option in Korea for reducing a square jaw or alleviating jaw tension. At BAILOR Clinic in Sinsa, Gangnam, this treatment is provided with precision to create a softer, more refined lower face silhouette or to relieve chronic jaw clenching teeth-grinding (bruxism) and TMJ symptoms.
What Is Masseter Botox?
The masseter muscle is a large chewing muscle located at the angle of the jaw. When it becomes over-developed due to genetics, clenching, or grinding, it can lead to a wider, angular jawline or discomfort in the temporomandibular joint (TMJ).
Masseter Botox works by injecting a small amount of botulinum toxin into the muscle to reduce its activity and volume gradually. The result: a slimmer jawline, softened facial contour, and reduced muscle-related symptoms.
Key Benefits
- Jawline slimming & contouring: Over 2-4 weeks, the treated muscle gradually reduces in bulk, yielding a more “V-line” or soft jaw appearance.
- Relief of jaw tension & teeth grinding (bruxism): Relaxing the masseter can ease associated headaches, joint pain, and muscle fatigue.
- Minimal downtime: The procedure is quick (typically under 15 minutes) and you can resume daily activities almost immediately.
- Affordable and accessible in Korea: Masseter Botox tends to be less expensive in Seoul than in many Western countries, while still offering high levels of precision and safety.
What to Expect at BAILOR Clinic
- Consultation & Assessment: We evaluate your jawline anatomy, muscle bulk, clenching/biting habits, facial proportions and desired outcome.
- Dosage Planning: Based on your anatomy and goals, we determine the amount of toxin needed for your masseters.
- Injection: After cleaning and marking the injection points, the toxin is injected into the masseter muscle. Some slight pressure or stinging may be felt, but it's well-tolerated.
- Aftercare Instructions: Avoid intense chewing, very hard foods, facial massages or heavy pressure on the jaw for the first few days.
- Results & Follow-Up:
- Initial softening visible within 1-2 weeks
- Significant reduction and contour change typically by 4-8 weeks
- Effects last about 4-6 months (may vary individually)
- Maintenance sessions may be recommended to maintain results
Ideal Candidate
- Individuals with a broad-looking lower face due to prominent masseter muscles
- People who clench or grind their teeth, have TMJ discomfort or recurring jaw tension
- Anyone seeking jawline refinement without surgery
- Those looking for quick, minimally invasive treatment with visible results
Considerations & Limitations
- Masseter Botox is not a bone reduction treatment—the change is due to muscle volume reduction, not altering bone structure.
- If you have very prominent masseter muscles or complex TMJ issues, you may require multiple sessions or adjunctive treatments (e.g., fillers, threads, or surgery).
- Results are temporary; repetition is needed to maintain effect.
- Side-effects may include mild bruising or tenderness; ensuring proper dosage and injection technique by a qualified doctor is key.
