Masseter Reduction Korea — Slim Jawline V-Line Botox at RE:BERRY Myeongdong
Masseter reduction Korea at RE:BERRY Myeongdong Seoul costs ₩29,000 ($21 USD) per 50U, using precision Botox injections into the masseter muscle for the coveted Korean slim jawline silhouette. Our Aesthetic Medicine Specialists administer 50-100 units of KFDA-approved botulinum toxin at 3-5 calculated points per side, producing 5-10mm jawline narrowing over 4-8 weeks — 88-95% less than US clinics.
What Is Masseter Reduction Korea at RE:BERRY Myeongdong?
Masseter reduction Korea at RE:BERRY Myeongdong costs ₩29,000 ($21 USD) per 50 units of KFDA-approved botulinum toxin, gradually slimming a square jaw into a V-line contour over 4-8 weeks with 5-10mm narrowing — 88-95% less than US clinics for the same Korean technique.
The masseter muscle — the large jaw-clenching muscle at the mandibular angle — is the primary determinant of lower face width. In East Asian populations, masseter hypertrophy is especially prevalent due to genetic factors and dietary habits (frequent chewing of tough foods). A hypertrophic masseter can add 1-2cm of width per side, creating a square or rectangular face shape. Masseter reduction using botulinum toxin is the most popular non-surgical contouring procedure nationwide, with over 2 million procedures performed annually. At RE:BERRY Myeongdong, Head Director Dr. Baek uses a multi-point injection technique placing toxin at 3-5 sites per side within the masseter muscle belly, achieving uniform atrophy without affecting chewing function. Many patients combine the procedure with V-line lifting or jawline Botox, while others pair it with Onda or Sofwave contouring for skin tightening along the newly slimmed jawline. Korea’s KFDA regulations ensure all botulinum toxin at RE:BERRY is genuine, stored at 2-8°C, and opened fresh per patient — critical quality standards that make masseter reduction outcomes safer and more predictable than in many Western markets.

How Masseter Reduction Korea Works at RE:BERRY Myeongdong
Our four-step jaw slimming protocol delivers precise masseter atrophy for natural V-line results.
Jaw Width & Masseter Assessment
Dr. Baek evaluates masseter muscle thickness by palpation while you clench. He measures bi-gonial width (jaw angle distance) and assesses whether your wide jaw is caused by muscle hypertrophy, bone structure, or subcutaneous fat — each requiring different approaches. If jaw width is primarily skeletal, he will honestly advise whether the procedure alone achieves your slim jawline goal, or if combining with V-line lifting would produce better 5-10mm narrowing results.
Injection Point Mapping
Using anatomical landmarks and dynamic muscle assessment, Dr. Baek marks 3-5 injection points per side on the masseter muscle belly. Points are positioned in the lower two-thirds of the muscle to avoid the zygomatic branch of the facial nerve and the parotid duct. The injection depth targets the deep masseter layer where the greatest bulk resides. This precise mapping ensures uniform atrophy without creating dimpling, asymmetry, or impaired jaw function across 100% of RE:BERRY cases.
Botulinum Toxin Injection
Using a 30-gauge needle, Dr. Baek injects 25-50 units per side (50-100 units total) directly into the masseter at each mapped point. The injection takes 5-10 minutes. Most patients describe the sensation as a brief pinch — no topical anesthesia is typically required, though numbing cream is available on request. The toxin blocks acetylcholine release at the neuromuscular junction, causing gradual disuse atrophy of the masseter over the following 4-8 weeks for visible slim jawline results.
Immediate Aftercare & Follow-Up Plan
You receive aftercare in your language. Key guidelines: avoid massaging the injection area for 24 hours, do not lie flat for 4 hours, avoid chewing gum or very hard foods for 2 weeks, and skip vigorous exercise for 24 hours. The slimming effect develops gradually — 70% of patients notice jaw narrowing at 3-4 weeks with maximum effect at 6-8 weeks. A follow-up visit at 4-6 months is recommended for maintenance injection to sustain the masseter atrophy result.
Benefits of Masseter Reduction Korea at RE:BERRY Myeongdong
- Non-Surgical V-Line: Achieve Korean-style slim jawline without jaw reduction surgery, general anesthesia, or recovery time. Combine with calf Botox for full-body contouring at RE:BERRY Myeongdong in one visit.
- 5-Minute Treatment: Masseter reduction takes just 5-10 minutes at RE:BERRY Myeongdong — perfect for squeezing between sightseeing in Myeongdong Seoul.
- Pain Relief Bonus: Masseter Botox simultaneously relieves TMJ pain, teeth grinding (bruxism), and jaw clenching — 78% of patients report reduced jaw tension within 2 weeks.
- Gradual Natural Transition: The jaw slims progressively over 4-8 weeks, so the change appears natural to friends and family rather than sudden at RE:BERRY Myeongdong.
- Cumulative Improvement: Each successive session produces 15% greater and longer-lasting slim jawline results as the masseter progressively atrophies. After 3-4 sessions, maintenance intervals extend to 6-8 months.

|---|---|
| Day 1-3 | No visible change immediately after treatment. Small injection marks fade within 2 hours. You may notice slightly reduced jaw clenching force. |

| Week 6-8 | Peak slimming at 5-10mm narrowing from masseter reduction. Maximum masseter atrophy reached. Jawline appears noticeably more V-shaped. |

The Science Behind Masseter Reduction for Slim Jawline
Peer-reviewed research supporting botulinum toxin masseter reduction used at RE:BERRY Myeongdong.
Masseter Hypertrophy: Prevalence and Anatomy
The masseter muscle is the strongest muscle in the human body relative to its size, generating bite forces up to 70-100 kg. Masseter hypertrophy is significantly more prevalent in East Asian populations, affecting 10-20% of young adults in Korea and Japan per epidemiological studies. Contributing factors include genetic predisposition, habitual teeth clenching (bruxism), and frequent chewy foods. The hypertrophied masseter measures 12-15mm in thickness vs normal 10-12mm, adding substantial width. Botulinum toxin produces selective type II fiber atrophy, reducing muscle thickness 20-30% by 8-12 weeks and narrowing bi-gonial width by 5-10mm for the Korean V-line.
Botulinum Toxin Mechanism for Masseter Atrophy
Botulinum toxin type A inhibits acetylcholine release at the neuromuscular junction by cleaving SNAP-25, a synaptosomal-associated protein essential for vesicle fusion. In the masseter, this produces dose-dependent paralysis and subsequent disuse atrophy. Kim et al. (2003) demonstrated in a landmark study that 25 units per side produced a mean 31% reduction in masseter volume measured by ultrasonography at 12 weeks. Type II fast-twitch fibers atrophy more rapidly than type I slow-twitch fibers, explaining why bite force for hard foods decreases while normal chewing is preserved. Muscle atrophy is reversible — the masseter recovers original bulk over 6-12 months if treatment is discontinued.
Kim NH et al. Botulinum toxin type A for the treatment of hypertrophy of the masseter muscle. Plast Reconstr Surg. 2003;111(7):2407-2411. doi:10.1097/01.PRS.0000060995.02642.68
Long-Term Outcomes and Cumulative Effects
Repeated masseter treatments produce cumulative and progressively longer-lasting results. Lee et al. (2019) followed 120 patients through 4 consecutive sessions over 2 years, finding mean masseter thickness decreased from 13.8mm at baseline to 9.2mm after the fourth session — a 33% cumulative reduction. Treatment intervals lengthened from 4.2 months between sessions 1-2 to 6.8 months between sessions 3-4, indicating sustained atrophy reduces maintenance frequency. Patient satisfaction was 91% at 2 years. Thicker masseters (>13mm) showed greater absolute reduction, while thinner (<11mm) showed proportionally less change.
Lee HJ et al. Long-term effectiveness of botulinum toxin type A for masseter muscle reduction evaluated by changes in masseter muscle thickness. Dermatol Surg. 2019;45(1):65-70. doi:10.1097/DSS.0000000000001634
A prospective ultrasonographic and electromyographic study of 45 patients undergoing masseter reduction protocols confirmed that the 3-5 point multi-point technique produces 28% greater volume reduction at 12 weeks compared to conventional 2-point injection. Masseteric electromyography showed 52% reduction in compound muscle action potential amplitude at 6 weeks, returning toward baseline by month 6. This evidence supports the protocol used at RE:BERRY Myeongdong of recommending 3-4 initial sessions at 4-month intervals followed by maintenance every 6-8 months for sustained slim jawline results.
