RE:BERRY Myeongdong delivers precision masseter botox for V-line jawline contouring using Korean premium botulinum toxin. Masseter botox in Myeongdong starts from just ₩29,000 for 50 units at our 365-day clinic, located 2 minutes from Myeongdong Station Exit 8, with full 8-language support for international visitors seeking non-surgical jaw reduction.
How Does Masseter Botox Work for Jawline Slimming in Myeongdong?
Masseter botox at RE:BERRY Myeongdong injects 50 units of Korean premium botulinum toxin into each masseter muscle to reduce jaw width by 15-30% over 4-8 weeks, creating a slimmer V-line facial contour starting from ₩29,000 per session with zero downtime.
Masseter botox in Myeongdong Seoul has become one of the most sought-after non-surgical facial contouring procedures for both Korean residents and international medical tourists. At RE:BERRY Myeongdong, masseter botox works by injecting precise doses of botulinum toxin type A into the masseter muscles, the large jaw-clenching muscles on each side of the face. Over 4-8 weeks, the toxin blocks acetylcholine release at the neuromuscular junction, causing controlled muscle atrophy that reduces jaw width by 15-30%. Head Director Seung-Jae Baek uses a multi-point injection technique with 3-5 injection sites per side for even distribution and natural-looking jawline slimming. Unlike surgical jaw reduction that requires general anesthesia and weeks of recovery, masseter botox at RE:BERRY Myeongdong takes just 10-15 minutes with immediate return to daily activities. The procedure also provides therapeutic relief for patients suffering from bruxism (teeth grinding) and TMJ-related jaw pain, making it both a cosmetic and functional treatment. For patients seeking additional contouring, masseter botox can be combined with chin filler to enhance the V-line effect, or with double chin treatment for comprehensive lower-face sculpting at RE:BERRY Myeongdong.

How Masseter Botox Treatment Works at RE:BERRY Myeongdong
A precise 4-step protocol for safe and effective jawline slimming with masseter botox.
Jaw Assessment & Muscle Analysis
Dr. Seung-Jae Baek evaluates your masseter muscle thickness by palpation while you clench your jaw. He measures the bigonial width (jaw angle to jaw angle) and assesses facial proportions to determine the optimal masseter botox dosage. Patients with Grade 3-4 masseter hypertrophy typically require 50-60 units per side, while mild cases may need 25-40 units. The consultation includes discussion of your aesthetic goals, whether primarily V-line contouring or bruxism relief, and takes 10-15 minutes in your preferred language. He also evaluates whether combining masseter botox with additional jawline treatments would enhance results.
Injection Site Mapping & Preparation
Using anatomical landmarks, the doctor marks 3-5 injection points per masseter muscle in the lower two-thirds of the muscle belly, avoiding the upper portion near the zygomatic arch and parotid gland. This precision mapping ensures even toxin distribution while preventing unintended weakening of the smile muscles (risorius and zygomaticus). The skin is cleansed with antiseptic solution. Ice or topical numbing may be applied for comfort, though most patients find masseter botox tolerable without anesthesia.
Precision Masseter Botox Injection
Using a 30-gauge ultrafine needle, the doctor delivers botulinum toxin into the deep masseter muscle belly at each marked point. The multi-point injection technique distributes 50 units across 3-5 sites per side, ensuring uniform muscle relaxation and avoiding lumpy or asymmetric results. Each injection takes 2-3 seconds. The total masseter botox procedure at RE:BERRY Myeongdong takes approximately 10-15 minutes for both sides. Patients feel a brief pinch sensation comparable to a mosquito bite at each injection point. Dr. Baek adjusts injection depth based on muscle thickness, typically 8-12mm for Korean patients.
Post-Injection Care & Follow-Up
Immediately after masseter botox injection, gentle pressure is applied to minimize bruising. Your aftercare coordinator provides instructions in your language: avoid massaging the jaw area for 24 hours, stay upright for 4 hours, skip strenuous exercise for 24 hours, and avoid hard or chewy foods for 48 hours. Initial jaw slimming becomes visible at 2-4 weeks as the masseter muscle begins to atrophy. Maximum V-line results appear at 6-8 weeks. RE:BERRY Myeongdong offers a complimentary follow-up assessment at 4 weeks to evaluate symmetry and determine if touch-up units are needed.

The Science Behind Masseter Botox for Jawline Slimming
Peer-reviewed evidence supporting botulinum toxin injection for masseter hypertrophy reduction and V-line contouring.
Botulinum Toxin for Masseter Muscle Hypertrophy
Botulinum toxin type A (BoNT-A) achieves masseter muscle reduction through denervation-induced atrophy. When injected into the masseter, BoNT-A binds to presynaptic cholinergic nerve terminals and cleaves SNARE proteins (specifically SNAP-25), blocking acetylcholine release at the neuromuscular junction. Without neural stimulation, the masseter muscle fibers undergo progressive disuse atrophy over 4-8 weeks. Ultrasonographic studies confirm that masseter botox reduces muscle thickness by 20-35% at 12 weeks post-injection, with corresponding jaw width reduction of 15-30% on frontal view. The effect is dose-dependent and reversible, with muscle function gradually returning over 4-6 months as new nerve sprouts form.
To EW et al. A prospective study of the effect of botulinum toxin A on masseteric muscle hypertrophy with ultrasonographic and electromyographic measurement. Br J Plast Surg. 2001;54(3):197-200. doi:10.1054/bjps.2000.3526
Optimal Dosing and Injection Technique
Clinical evidence supports 25-50 units of BoNT-A per masseter as the effective range for cosmetic jaw reduction, with higher doses (50-60 units) recommended for Grade 3-4 hypertrophy. A multi-point injection pattern using 3-5 sites per muscle in the lower two-thirds of the masseter belly produces more uniform atrophy compared to single-point injection. Studies demonstrate that confining injections to the lower masseter avoids weakening the temporalis and lateral pterygoid muscles, preserving normal mastication while achieving optimal cosmetic reduction. The multi-point technique also reduces the risk of smile asymmetry by keeping the toxin away from the risorius and zygomaticus major muscles.

Long-Term Efficacy and Cumulative Effects
Longitudinal studies show that repeated masseter botox injections produce cumulative and increasingly durable results. After 3 or more consecutive treatment cycles at 4-6 month intervals, patients experience prolonged muscle reduction with intervals extending to 8-12 months between maintenance sessions. Histological analysis reveals that chronic denervation leads to replacement of type II fast-twitch muscle fibers with smaller type I fibers, resulting in a fundamentally smaller muscle mass. This cumulative remodeling means that patients who maintain regular masseter botox at RE:BERRY Myeongdong require progressively fewer units over time.
Xie Y et al. Long-term effect of botulinum toxin A on lateral pterygoid muscle and temporomandibular joint after repeated injection. Am J Phys Med Rehabil. 2015;94(10):e84-91. doi:10.1097/PHM.0000000000000311
A comprehensive meta-analysis reviewing 22 studies on masseter botox for aesthetic and therapeutic indications confirmed that BoNT-A injection is a safe and effective non-surgical alternative to surgical mandibular angle reduction, with a complication rate below 2% and patient satisfaction rates exceeding 90% across all studies analyzed.

What Patients Say About Masseter Botox at RE:BERRY Myeongdong
“I was nervous about getting masseter botox but Dr. Baek explained everything clearly in English. The injections took maybe 10 minutes. By week 6, my jawline was noticeably slimmer and my friends kept asking if I lost weight. The ₩29,000 price was unbelievable compared to what I would pay back home.”
“I came for jaw slimming but was surprised that my nighttime teeth grinding almost completely stopped after masseter botox. Two benefits in one treatment. RE:BERRY Myeongdong was easy to find from the subway station and everything was in Japanese too.”
“This was my third session of masseter botox at RE:BERRY and the V-line effect is lasting longer each time. Dr. Son said I needed fewer units this round because the muscle had gotten smaller from previous treatments. Very professional clinic.”
