What Is Masseter Botox and How Does It Create a V-Line?
Masseter Botox is a non-surgical jawline slimming treatment in which KFDA-approved botulinum toxin Type A is injected into the masseter (jaw clenching) muscles to reduce their volume over time. The masseter is one of the strongest muscles in the human body, and when overdeveloped — due to genetics, habitual clenching, or bruxism — it creates a wide, square jawline. Botulinum toxin temporarily weakens the muscle, causing gradual atrophy that produces a slimmer, more V-shaped facial contour within 4-8 weeks. This is one of the most popular aesthetic treatments in Korea, where V-line facial proportions are highly desired.
The masseter muscle originates from the zygomatic arch and inserts into the mandibular ramus and angle. When hypertrophied, it visibly widens the lower face, creating the ‘square jaw’ appearance. Botulinum toxin Type A works by blocking acetylcholine release at the neuromuscular junction, preventing the masseter from contracting at full force. Without regular forceful contraction, the muscle undergoes disuse atrophy — a physiological process in which muscle fibers decrease in size. Clinical studies using ultrasonography have documented an average 31% reduction in masseter muscle thickness at 12 weeks post-injection (Kim et al., J Oral Maxillofac Surg, 2010; doi:10.1016/j.joms.2009.07.014). At RE:BERRY Incheon Airport, Dr. Cho Sung-Jun and Dr. Kim Dong-Young perform all masseter Botox injections personally, tailoring the dosage (typically 25-50 units per side) and injection pattern to each patient’s muscle bulk, facial symmetry, and aesthetic goals. The treatment takes just 10-15 minutes with zero downtime — ideal for travelers at Incheon International Airport. For enhanced jawline contouring, masseter Botox can be combined with chin filler (Juvederm 1cc + Korean chin Botox at ₩390,000) or Sofwave lifting for comprehensive facial reshaping. Patients experiencing jaw tension, teeth grinding (bruxism), or TMJ disorder also benefit significantly from masseter Botox, as the therapeutic muscle relaxation relieves these conditions while simultaneously providing the cosmetic V-line effect.

How Masseter Botox V-Line Treatment Works at RE:BERRY
A precise four-step protocol for non-surgical jawline slimming. Total visit time: approximately 30-45 minutes.
Jawline Assessment & Muscle Palpation
Dr. Cho Sung-Jun or Dr. Kim Dong-Young performs a thorough jawline assessment. You will be asked to clench your jaw firmly while the doctor palpates (feels) the masseter muscle on both sides to evaluate muscle thickness, symmetry, and the degree of hypertrophy. The doctor also assesses your overall facial proportions, chin projection, and lower face width relative to your cheekbones and forehead to determine the optimal treatment plan. If you experience bruxism (teeth grinding) or TMJ pain, this is also evaluated. The number of units and injection pattern are customized to achieve your desired V-line result while maintaining natural jaw function for chewing and speaking.
Preparation & Comfort Measures
The jawline area is cleansed with antiseptic solution. For most patients, masseter Botox requires no numbing — the masseter is a thick muscle, and the ultra-fine 30-32 gauge needles create minimal sensation through the overlying skin. Ice application is available for sensitive patients. The KFDA-approved botulinum toxin is prepared fresh, reconstituted to the precise concentration required for your calculated dosage. All products are verified genuine with intact seals and cold-chain documentation.
Precision Masseter Injection
Using ultra-fine 30-32 gauge needles, the doctor injects 25-50 units of botulinum toxin per side into 3-5 strategic points within the masseter muscle. The injection points are placed in the lower two-thirds of the muscle belly to avoid the parotid duct and to target the thickest portion for maximum volume reduction. Each injection takes seconds. The entire injection phase takes approximately 5-10 minutes for both sides. Dr. Cho and Dr. Kim use their extensive experience with Asian facial anatomy to ensure symmetric results and natural jaw contour.
Post-Treatment & V-Line Development
Brief ice application to minimize any bruising risk. The doctor provides specific aftercare instructions: avoid hard or chewy foods (steak, gum, jerky) for 24-48 hours to minimize muscle use during the toxin binding period. Avoid rubbing the jaw area for 24 hours. No intense exercise for 24 hours. The masseter begins weakening within 3-7 days, but visible jawline slimming develops gradually over 4-8 weeks as the muscle atrophies. Peak V-line results are typically seen at 6-8 weeks. RE:BERRY offers video follow-up consultation for international patients to assess results and determine if touch-up is needed.
What to Expect from Masseter Botox at RE:BERRY Incheon Airport
- Non-Surgical V-Line: Achieve the coveted Korean V-line jawline without jaw surgery (mandibular angle reduction). Masseter Botox is a 10-minute procedure with zero downtime, compared to 2-4 weeks recovery for surgical jawline contouring.
- Significant Volume Reduction: Clinical studies demonstrate an average 31% reduction in masseter muscle thickness at 12 weeks (Kim et al., 2010). This translates to visibly slimmer, more tapered jawline contours.
- Dual Cosmetic + Therapeutic Benefit: Masseter Botox simultaneously slims the jawline (cosmetic) and relieves bruxism/TMJ pain (therapeutic). One treatment addresses both square jaw concerns and teeth grinding.
- Zero Downtime: No swelling, no bandages, no activity restrictions beyond avoiding hard foods for 24-48 hours. Fly, work, and socialize immediately. The perfect traveler treatment.
- Long-Lasting Results: V-line effects last 4-6 months from a single session. With repeated treatments, the masseter progressively weakens, and many patients require fewer units and less frequent maintenance over time.
- Natural Jaw Function Preserved: Dr. Cho and Dr. Kim carefully calibrate dosage to slim the muscle bulk while preserving normal chewing and speaking function. The goal is aesthetic refinement, not functional impairment.
| Timeline | What to Expect |
|---|---|
| Day 1 | Tiny pinprick marks fade within minutes. No visible swelling or bruising in most patients. Continue all normal activities except hard chewing for 24-48 hours. |
| Day 3-7 | Botulinum toxin begins binding to nerve terminals. You may notice it becomes harder to clench your jaw forcefully. No visible slimming yet — the muscle needs time to atrophy. |
| Week 2-4 | Masseter muscle begins to soften and reduce in bulk. Early V-line slimming may be noticed when touching the jawline area. Bruxism and jaw tension patients notice significant relief. |
| Week 4-6 | Visible jawline slimming progresses. The lower face appears narrower, especially when viewed from the front. Friends and family may begin commenting on the change. |
| Week 6-8 | Peak V-line results. Maximum masseter atrophy achieved. The jawline is at its slimmest. Facial proportions appear more balanced and tapered. |
| Month 4-6 | Muscle activity gradually returns as nerve endings regenerate. Masseter begins to regain some volume. This is the optimal time for a maintenance session to sustain the V-line effect. |

The Science Behind Masseter Botox and V-Line Jawline Slimming
Peer-reviewed research supporting botulinum toxin for masseter muscle reduction, jawline contouring, and bruxism treatment.
Masseter Hypertrophy: Why Some Jaws Appear Square
The masseter muscle is one of the four muscles of mastication and one of the strongest muscles in the human body relative to its size, capable of generating up to 70 kg (154 lbs) of force at the molar teeth. In some individuals, the masseter becomes hypertrophied (enlarged) due to genetic predisposition, habitual clenching (bruxism), frequent gum chewing, or stress-related jaw tension. Masseter hypertrophy is particularly common in East Asian populations, where it is a leading reason patients seek jawline contouring. The enlarged muscle creates visible bulk at the mandibular angle, producing a wide, square lower face that contrasts with the narrower upper face. Unlike bone-based jawline width (which requires surgical modification), muscle-based jawline width responds beautifully to botulinum toxin — a non-surgical approach that gradually reduces muscle volume through controlled disuse atrophy.
Mechanism: Controlled Disuse Atrophy
When botulinum toxin is injected into the masseter, it blocks acetylcholine release at the neuromuscular junction, preventing full muscle contraction. The masseter continues to function for basic chewing and speaking (only partial denervation is intended), but it can no longer generate maximum force. Without regular forceful contraction, the muscle fibers undergo disuse atrophy — a well-documented physiological response in which individual myocytes (muscle cells) decrease in diameter. This is the same process that causes muscle shrinkage during immobilization (e.g., a limb in a cast). The clinical result is a gradual, progressive slimming of the jawline that appears entirely natural because the change occurs slowly over weeks rather than abruptly.
Clinical Evidence: Ultrasonographic Measurements
Kim et al. (2010) conducted a prospective study published in the Journal of Oral and Maxillofacial Surgery demonstrating that a single session of botulinum toxin injection (25 units per side) into the masseter produced an average 31% reduction in muscle thickness as measured by ultrasonography at 12 weeks post-injection. To et al. (2001) reported similar findings in the International Journal of Oral and Maxillofacial Surgery, documenting significant masseter volume reduction at 3 months with high patient satisfaction. A systematic review by Fedorowicz et al. (2013) analyzing 4 randomized controlled trials confirmed that botulinum toxin is an effective, safe, and reversible treatment for masseteric hypertrophy, with the most common side effect being transient difficulty chewing hard foods (8% of patients).
Bruxism and TMJ Relief: The Therapeutic Dimension
Masseter Botox provides significant therapeutic benefits beyond cosmetic jawline slimming. Guarda-Nardini et al. (2008) published in the Journal of Oral Rehabilitation that botulinum toxin injection into the masseters reduced bruxism-related symptoms (jaw pain, headache, tooth sensitivity) by an average of 65% at 1 month. For TMJ disorder, Schwartz et al. (2002) in the Journal of Oral and Maxillofacial Surgery demonstrated significant pain reduction and improved jaw function in 90% of patients treated with masseter botulinum toxin. The International Headache Society recognizes bruxism as a contributor to chronic tension-type headache, meaning masseter Botox can also indirectly reduce headache frequency in bruxism patients.

What Our Patients Say About Masseter Botox at RE:BERRY
“I flew from Taipei to Incheon specifically for V-line Botox. Dr. Cho assessed my jaw carefully and recommended 40 units per side. Six weeks later, my jawline is dramatically slimmer — people think I lost weight. The whole treatment took 10 minutes. I could not believe how easy it was compared to the jaw surgery I had been considering.”
“I had been grinding my teeth for years and my masseter muscles were huge. After masseter Botox at RE:BERRY Incheon Airport, my jaw pain disappeared within a week, and my face looked much slimmer by 6 weeks. It solved both my medical and aesthetic concerns in one treatment. The Chinese-speaking coordinator made everything smooth.”
“As a frequent flyer through Incheon, I now schedule my masseter Botox touch-ups around my layovers. The convenience is unbeatable — 10 minutes, zero downtime, and my V-line is maintained year-round. Dr. Kim adjusts the dosage each time based on how my muscles have responded. Truly personalized care.”
Frequently Asked Questions About Masseter Botox at RE:BERRY Incheon Airport
Expert answers to common questions about V-line jaw slimming with masseter Botox near Incheon International Airport.
Masseter Botox pricing is available upon consultation as dosage varies by muscle thickness (typically 25-50 units per side). Korean wrinkle Botox starts at ₩9,900 per site. For V-line jawline enhancement, consider the Juvederm chin filler + chin Botox package at ₩390,000 (regular ₩700,000).
Most patients require 25-50 units per side (50-100 units total) depending on masseter muscle thickness and desired slimming degree. Dr. Cho and Dr. Kim assess your muscle bulk by palpation and recommend the optimal dosage during consultation.
The muscle begins weakening within 3-7 days. Early slimming is felt (not yet visible) at 2-3 weeks. Visible jawline narrowing typically appears at 4-6 weeks, with peak V-line results at 6-8 weeks post-injection.
V-line results from masseter Botox typically last 4-6 months. With repeated treatments (every 4-6 months), the muscle progressively weakens and many patients find they need lower doses and less frequent sessions over time.
Most patients rate the discomfort at 1-2 out of 10. The masseter is a thick muscle, and the ultra-fine 30-32 gauge needles pass through quickly. Each injection point takes less than a second. Ice is available for sensitive patients.
No. Dr. Cho and Dr. Kim calibrate the dosage to reduce muscle bulk while preserving normal chewing function. You may notice slightly reduced jaw power for very hard or chewy foods during the first 2 weeks, but normal eating is unaffected. This temporary reduction in bite force is actually part of the therapeutic mechanism.
Yes. Masseter Botox is commonly combined with chin filler + chin Botox (₩390,000) for enhanced V-line proportion, or with Sofwave lifting for lower face tightening. Very Slim Contour Injection (₩69,000) can address submental fat for a sharper jawline.
Yes. Masseter Botox is clinically proven to reduce bruxism symptoms by an average of 65% (Guarda-Nardini et al., 2008). By weakening the masseter muscles, the involuntary clenching that causes teeth grinding, jaw pain, and headaches is significantly reduced. You get V-line slimming as a cosmetic bonus.
No. Masseter Botox slims the jaw by reducing muscle volume (non-surgical, 10 minutes, zero downtime). Jaw surgery (mandibular angle reduction) reshapes the jaw bone (invasive, general anesthesia, 2-4 weeks recovery). Masseter Botox is ideal for muscle-based square jaws; surgery may be needed for bone-based jawline width.
Initially every 4-6 months. After 3-4 consecutive treatments, many patients can extend intervals to 6-8 months as the muscle progressively atrophies with less force generation. Some long-term patients maintain V-line results with just 1-2 sessions per year.
Yes. Masseter Botox has zero downtime. You can fly immediately after treatment. The only recommendations are to avoid hard chewing and jaw rubbing for 24-48 hours — easy to follow during travel.
Both use the same KFDA-approved botulinum toxin Type A. Wrinkle Botox targets small facial expression muscles (forehead, glabella, crow’s feet) with lower doses (10-30 units). Masseter Botox targets the large jaw-clenching muscle with higher doses (50-100 units total) to reduce its volume for jawline slimming. See our general Botox page for wrinkle treatment details.
Yes. Botulinum toxin is 100% temporary. If you decide you prefer your original jawline, simply discontinue treatment and the masseter will return to its original size over 4-6 months as nerve function fully recovers.
Ideal candidates have a visibly square or wide jawline due to masseter muscle hypertrophy (not bone structure), desire a slimmer V-line without surgery, and/or suffer from bruxism or TMJ pain. Dr. Cho can determine during consultation whether your jaw width is primarily muscular or skeletal.
Yes. Masseter Botox is popular among both men and women. For men, dosage may be higher (50+ units per side) due to larger muscle mass. Some men seek masseter Botox primarily for bruxism/TMJ relief, with the slimming effect being secondary.
Masseter Botox can actually improve jaw asymmetry. Dr. Cho and Dr. Kim assess both sides independently and may inject different dosages per side to create more balanced proportions. Correcting masseter asymmetry is a common and effective application.
Onda Coolwaves targets subcutaneous fat and skin laxity using RF + microwave technology. Masseter Botox targets muscle bulk. For patients with both a thick masseter and submental fat, combining both treatments provides comprehensive jawline contouring.
Yes. RE:BERRY Incheon Airport provides consultation and care in 8 languages: English, Japanese, Chinese (Simplified and Traditional), Thai, Vietnamese, Mongolian, and Persian. Multilingual coordinators assist every appointment.
