Masseter Botox in Seoul | Jaw Slimming & Functional Relief at BAILOR Clinic

Introduction

Jawline contouring through Botulinum toxinโ€‘type 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

  1. Consultation & Assessment: We evaluate your jawline anatomy, muscle bulk, clenching/biting habits, facial proportions and desired outcome.
  2. Dosage Planning: Based on your anatomy and goals, we determine the amount of toxin needed for your masseters.
  3. 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.
  4. Aftercare Instructions: Avoid intense chewing, very hard foods, facial massages or heavy pressure on the jaw for the first few days.
  5. 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.
