What Is Masseter Botox?
The masseter is the primary chewing muscle on either side of the jaw. In many East Asian patients, this muscle is naturally large or has hypertrophied from chewing habits or bruxism (teeth grinding), creating a square facial silhouette.
Botulinum toxin injected into the masseter temporarily reduces muscle activity, causing the muscle to gradually shrink over 4–6 weeks. The result: a softer, slimmer lower face — with no surgery and no downtime.
Why Seoul for Jaw Botox?
✦ Deep expertise in East Asian facial anatomy — Seoul practitioners have treated thousands of Asian patients with similar facial structure, providing highly calibrated dosing.
✦ Precise volumetric dosing — tailored to masseter size and desired outcome, avoiding the over-reduced “skeletal” look.
✦ Mandarin-speaking service at Rappoel — communicate your goals in Chinese, no risk of misunderstanding.
✦ Competitive pricing — high-quality jaw botox in Seoul is generally more affordable than equivalent treatments in Taiwan or Hong Kong.
What Makes Rappoel’s Approach Different?
Every masseter botox treatment at Rappoel is performed personally by the director, who brings 18+ years of injection aesthetics experience. Key aspects of Rappoel’s approach:
- Multi-point injection technique: Distributes toxin evenly across the masseter for uniform, natural reduction.
- Holistic facial balance: Slimming the jaw affects overall facial proportions. The director assesses forehead, cheekbone, and chin relationships to ensure the final result is harmonious.
- Conservative-first philosophy: Start with a precisely calibrated dose — avoid over-treatment on the first session.
How Long Does Jaw Botox Last?
| Session | Duration | Notes |
|---|---|---|
| 1st treatment | 4–6 months | Noticeable masseter reduction, clear facial slimming |
| 2nd treatment | 6–8 months | Muscle continues to atrophy, longer-lasting result |
| 3rd+ treatment | 8–12+ months | Sustained slim silhouette with less frequent maintenance |
