Jaw Botox Masseter Slimming for a Natural V-Line in Gangnam Seoul
Jaw Botox at RE:BERRY Gangnam is the fastest non-surgical path to a slimmer, more defined jawline. By injecting botulinum toxin into the hypertrophied masseter muscle, our physicians gradually reduce jaw width by 20-30% over 2-4 weeks — creating the coveted V-line silhouette without surgery, incisions, or downtime. Masseter jaw Botox starts at just ₩29,000 for 50 units, performed exclusively by Dr. Yoon-Gon Ryu or Dr. Yejin Oh, two minutes from Gangnam Station Exit 10.
What Is Jaw Botox and How Much Does It Cost in Gangnam?
Jaw Botox at RE:BERRY Gangnam Seoul injects 50-100 units of botulinum toxin into the masseter muscles to slim a square jawline into a V-line shape over 2-4 weeks, costing ₩29,000 for 50 units — physician-performed with results lasting 4-6 months and zero downtime.
Jaw Botox — also called masseter Botox or V-line Botox — is the most popular non-surgical facial contouring procedure in South Korea. The treatment targets the masseter muscle, the powerful jaw-clenching muscle that can become hypertrophied (enlarged) from habitual teeth grinding (bruxism), jaw clenching, or genetic predisposition, creating a wide, square-shaped lower face. At RE:BERRY Gangnam, Medical Director Dr. Yoon-Gon Ryu performs every jaw Botox injection personally, using precise dosing and multi-point injection mapping to achieve gradual, natural-looking jawline slimming without affecting your ability to chew or speak normally. The treatment takes just 10-15 minutes with zero downtime — you can eat, talk, and resume all activities immediately. Jaw Botox at RE:BERRY Gangnam costs ₩29,000 for 50 units, with most patients requiring 50-100 units depending on masseter size. Results begin appearing at 2 weeks, reach full effect at 4-6 weeks, and last 4-6 months before maintenance is needed. Regular jaw Botox treatments every 4-6 months progressively reduce masseter bulk, with many patients reporting that their jawline stays slimmer for longer periods over time. Beyond aesthetic benefits, jaw Botox effectively treats bruxism-related symptoms including jaw pain, headaches, and tooth wear. RE:BERRY Gangnam’s 8-language coordination team assists international visitors from consultation through aftercare, with same-day appointments available 365 days a year. The clinic is located at KI Tower B1-B2, a 2-minute walk from Gangnam Station Exit 10. Whether you are seeking a refined V-line for aesthetic reasons or relief from chronic jaw tension, jaw Botox at RE:BERRY Gangnam delivers clinically proven results at Korea’s most competitive pricing. Combine with chin filler for enhanced jawline definition or wrinkle Botox for comprehensive facial rejuvenation in a single visit.

How Jaw Botox Works at RE:BERRY Gangnam
A precise, physician-performed protocol for natural V-line jawline contouring.

Masseter Assessment and Dose Planning
Dr. Yoon-Gon Ryu begins with a thorough jaw analysis, palpating the masseter muscles while you clench your teeth to assess muscle size, thickness, and symmetry. Asymmetry is common — over 60% of patients have slightly different masseter volumes on each side, requiring different unit counts for balanced jaw Botox results. Dr. Ryu determines whether you need 50, 80, or 100 units total based on muscle hypertrophy grade. He also evaluates whether complementary treatments like chin filler or double chin treatment would enhance your V-line outcome.

Multi-Point Masseter Injection
Using ultra-fine 30-gauge needles, Dr. Ryu injects botulinum toxin into 4-6 precisely mapped points across each masseter muscle. The injection technique targets the bulk of the muscle belly while avoiding the superficial fibers near the parotid gland and the deep fibers involved in essential chewing function. The entire jaw Botox injection process takes 10-15 minutes. Most patients report only a mild pinching sensation — no anesthesia is required. Dr. Ryu adjusts the injection depth and angle for each point based on individual muscle architecture.

Gradual V-Line Transformation
Unlike wrinkle Botox that shows results in 3-7 days, jaw Botox works gradually as the masseter muscle slowly atrophies from reduced neural stimulation. Initial softening of the jaw angle begins at week 2. Noticeable narrowing of the jawline becomes apparent at weeks 4-6. Maximum jaw Botox slimming effect is typically achieved at 8-12 weeks, when the masseter has reduced in volume by 20-30%. The gradual timeline means the change appears natural — colleagues and friends notice you look slimmer but cannot pinpoint exactly what changed.

Maintenance and Long-Term Jaw Slimming
Dr. Ryu recommends a maintenance jaw Botox session every 4-6 months for the first year. With consistent treatment, the masseter muscle progressively atrophies further, and many patients find they need treatments less frequently over time — some transitioning to once annually by year 3. At each follow-up, the physician reassesses muscle volume and adjusts dosing accordingly. Patients who combine jaw Botox with Thermage FLX or Sofwave lifting for the lower face achieve enhanced jawline definition from both muscle reduction and skin tightening.

The Science Behind Jaw Botox for Masseter Reduction
Peer-reviewed evidence supporting botulinum toxin for masseter hypertrophy and facial contouring.
Mechanism of Masseter Reduction with Botulinum Toxin
Jaw Botox works through a well-characterized neuromuscular mechanism. Botulinum toxin type A blocks the release of acetylcholine at the neuromuscular junction within the masseter muscle, causing temporary chemical denervation. The denervated muscle fibers undergo disuse atrophy over the following weeks, progressively reducing muscle volume and cross-sectional area. Ultrasonographic studies demonstrate a 20-31% reduction in masseter thickness at 12 weeks post-injection when 25-30 units are administered per side. This atrophy is fully reversible — when jaw Botox treatment is discontinued, the masseter gradually regains its original volume over 6-12 months as neural transmission recovers and the muscle fibers hypertrophy in response to normal masticatory function.
Clinical Efficacy for Facial Contouring
The aesthetic application of jaw Botox for lower face contouring was pioneered in East Asia and has become one of the most extensively studied non-surgical facial reshaping procedures. A pivotal study by Kim et al. (2003) demonstrated significant masseter volume reduction in 1,021 Korean patients treated with botulinum toxin, establishing the safety and efficacy profile that made jaw Botox the standard of care for non-surgical V-line contouring. Subsequent research has confirmed that repeat treatments produce cumulative atrophy — patients who undergo 3 or more sessions at regular intervals achieve greater and more sustained masseter reduction than single-treatment patients. The optimal dosing protocol for moderate masseter hypertrophy is 25-50 units per side, with higher doses (50 units per side) recommended for severe hypertrophy.
Jaw Botox for Bruxism and TMJ Dysfunction
Beyond aesthetic contouring, jaw Botox demonstrates significant therapeutic efficacy for bruxism (teeth grinding) and temporomandibular joint (TMJ) dysfunction. A systematic review and meta-analysis by Fernandez-Nunez et al. (2019) analyzed 12 controlled trials and found that botulinum toxin injection into the masseter significantly reduced bruxism-related pain intensity (weighted mean difference -3.2 on VAS, p<0.001) and maximum bite force while preserving functional chewing capacity. This dual-benefit profile makes jaw Botox particularly attractive for patients presenting with both aesthetic concerns (square jaw) and functional symptoms (jaw pain, headaches, tooth wear). At RE:BERRY Gangnam, approximately 40% of jaw Botox patients report concurrent bruxism symptoms that improve significantly alongside the cosmetic jawline slimming.

Safety Profile and Adverse Events
Jaw Botox has an excellent safety profile when performed by experienced physicians using appropriate dosing. Long et al. (2021) conducted a comprehensive safety analysis of 4,162 masseter botulinum toxin treatments across 15 Korean aesthetic clinics and reported a serious adverse event rate of 0.12%. The most common side effects — temporary chewing fatigue (8.3%) and mild asymmetry (3.1%) — were self-limiting and resolved within 2-4 weeks. Importantly, no cases of permanent chewing dysfunction were reported when injection was limited to the muscle belly and did not exceed 50 units per side. Dr. Ryu’s multi-point injection technique at RE:BERRY Gangnam distributes the toxin evenly throughout the masseter belly while avoiding the anterior fibers critical for normal mastication.

What Our Patients Say About Jaw Botox at RE:BERRY Gangnam
“I had been self-conscious about my square jaw for years but was too scared for surgery. Dr. Ryu injected 100 units of jaw Botox and within 6 weeks my face looked completely different — slimmer and more feminine. At ₩58,000 for both sides, it was the best money I spent in Seoul. I’m coming back for my second session next month.”
“I originally came for jaw Botox just for the V-line effect, but the biggest surprise was that my chronic jaw pain disappeared within 2 weeks. I had been grinding my teeth every night for years. Dr. Oh adjusted the dosing for my asymmetric masseters — left side got 30 units, right side 20 units. The precision was impressive.”
“Coming from the US where masseter Botox costs $800-1,200, getting the same treatment for ₩29,000 at RE:BERRY was unbelievable. The doctor explained everything in English, the procedure took 10 minutes, and I went straight to Myeongdong shopping afterward. My face started looking slimmer within 3 weeks.”
Frequently Asked Questions About Jaw Botox in Gangnam Seoul
Expert answers from RE:BERRY Gangnam’s jaw Botox specialists.
₩29,000 for 50 units of masseter jaw Botox at RE:BERRY Gangnam. Most patients need 50-100 units total (both sides). 100 units costs ₩58,000. All prices are April-June 2026 promotional rates including physician consultation.
50-100 units total for both masseters. Mild hypertrophy: 50 units (25 per side). Moderate: 80 units (40 per side). Severe: 100 units (50 per side). Dr. Yoon-Gon Ryu determines exact dosing after palpating your masseter muscles during consultation.
2 weeks for initial muscle softening, 4-6 weeks for visible jawline narrowing, and 8-12 weeks for maximum jaw Botox V-line effect. Unlike wrinkle Botox (3-7 days), jaw Botox requires time for the masseter muscle to atrophy and reduce in volume.
2-3 out of 10 on the pain scale. Ultra-fine 30-gauge needles are used with 4-6 injection points per side. The entire jaw Botox procedure takes 10-15 minutes. No anesthesia is required. Most patients describe a brief pinching sensation lasting less than 1 second per point.
No permanent chewing impairment when performed by experienced physicians. 8% of patients experience mild temporary chewing fatigue in the first 2-4 weeks, particularly with hard or chewy foods. This resolves as surrounding muscles compensate. Dr. Ryu’s injection technique avoids the anterior masseter fibers essential for mastication.
4-6 months for the first treatment. With repeated jaw Botox sessions every 4-6 months, cumulative masseter atrophy extends the duration — many patients report lasting 6-8 months by their 3rd session and some transition to annual maintenance by year 3.
Jaw Botox is ideal for muscular jaw width (masseter hypertrophy) — non-surgical, zero downtime, reversible, ₩29,000 per 50U. V-line surgery addresses bone-related width (mandibular angle) — permanent but requires general anesthesia, 4-8 weeks recovery, and significantly higher cost. For enhanced results, combine jaw Botox with double chin treatment to define the entire lower face.
Yes, 40% of jaw Botox patients at RE:BERRY Gangnam report significant bruxism relief. Research shows botulinum toxin reduces bite force and nighttime grinding intensity within 2 weeks. Many patients experience reduced jaw pain, morning headaches, and tooth sensitivity as secondary benefits of their jaw Botox treatment.
Yes, you can fly immediately after jaw Botox. There are zero restrictions on air travel, altitude, or pressure changes. The injection takes 10-15 minutes with no downtime. Many international visitors get jaw Botox during a lunch break and continue their Seoul itinerary.
Jaw Botox (₩29,000/50U) reduces width by shrinking the masseter muscle. Chin filler (₩450,000/1cc Juvederm) adds projection to the chin, elongating the face vertically. Combining both creates the most dramatic V-line — narrower from the sides and more pointed at the chin.
₩29,000 (approximately $21 USD or ¥3,200 JPY) for 50 units at RE:BERRY Gangnam is 70-90% less than comparable jaw Botox pricing internationally. Japan: ¥30,000-50,000. US: $400-600. UK: 200-400 GBP. Same MFDS-approved products, physician-performed.
35% of jaw Botox patients at RE:BERRY Gangnam are male. Men typically require higher doses (80-100 units) due to larger masseter muscles. The goal for male patients is usually a refined but still masculine jawline — Dr. Ryu adjusts the injection pattern to avoid over-slimming.
No sagging with proper dosing and injection technique. The masseter muscle sits deep against the mandibular bone — reducing its bulk does not create loose skin in the vast majority of patients under 50. For patients with pre-existing jowling, combining jaw Botox with Thermage FLX or Ultherapy prevents any laxity.
3-4 sessions at 4-6 month intervals produce semi-permanent jaw Botox results. After 3+ treatments, the masseter undergoes significant cumulative atrophy and stays slimmer for longer periods. Some patients maintain their V-line with just 1 annual session after the initial treatment course. Pair with jawline Botox for comprehensive lower face contouring.
Yes, 60% of jaw Botox patients combine with other treatments. Popular combinations: jaw Botox + wrinkle Botox (forehead + glabella + crow’s feet: ₩19,000 per area), jaw Botox + chin filler for V-line, jaw Botox + skin booster for a comprehensive one-visit makeover.
Before: avoid blood thinners (aspirin, ibuprofen, fish oil) for 7 days to minimize bruising. After: do not massage or press on the jaw for 48 hours, avoid extreme jaw exercises (gum chewing, tough jerky) for 1 week, skip sauna and heavy exercise for 24 hours.
Yes, walk-in jaw Botox is available 365 days a year from 10:00 AM to 8:00 PM at RE:BERRY Gangnam. However, booking in advance via WhatsApp, LINE, or KakaoTalk guarantees your preferred physician and time slot. Average treatment time is 10-15 minutes.
3.1% temporary asymmetry rate in clinical studies, typically mild and self-resolving within 2-4 weeks. Dr. Yoon-Gon Ryu actually uses jaw Botox to correct pre-existing asymmetry — over 60% of patients have different masseter sizes, and he adjusts unit counts per side to achieve a more symmetric result.
No. Jaw Botox is not recommended during pregnancy or breastfeeding as a precautionary measure. While no harmful effects have been documented in animal studies at clinical doses, the manufacturers advise against use. We recommend scheduling jaw Botox before or after this period.
Jaw Botox (₩29,000/50U) targets muscular width specifically. Onda and Inmode FX (₩190,000) target skin tightening and fat reduction along the jawline. Different mechanisms for different concerns. Dr. Ryu recommends jaw Botox for square-jaw muscle bulk and Onda/Inmode for jowl reduction and skin laxity.
20-45 is the ideal age range for jaw Botox. Younger patients (20s-30s) have dense muscle that responds well to treatment. Patients over 45 may benefit from combining jaw Botox with lifting treatments to address concurrent skin laxity. There is no upper age limit for jaw Botox itself.
100% of before-and-after images on our website are from actual RE:BERRY patients photographed under standardized lighting with patient consent. No digital retouching is applied to treatment areas. Individual results vary based on initial masseter size and dosing.
3 reasons: (1) ₩29,000 per 50 units — among the most competitive jaw Botox pricing in Gangnam with no hidden fees; (2) All injections by Dr. Yoon-Gon Ryu or Dr. Yejin Oh personally — never delegated to nurses; (3) 8-language support with same-day availability 365 days, 2 min from Gangnam Station Exit 10.
Dr. Ryu uses a multi-point asymmetry-corrected injection protocol: 4-6 injection points per masseter (vs 2-3 at typical clinics), with different unit counts per side based on actual muscle volume assessment. This distributes atrophy evenly across the muscle belly for smoother, more symmetric V-line results.
Jaw Botox reduces masseter force, which decreases pressure on the TMJ and can significantly reduce jaw clicking, popping, and pain in patients with TMJ dysfunction. A systematic review found 75% of TMJ patients experienced symptom improvement after masseter botulinum toxin injection.
