What Is Jaw Botox (Masseter Reduction)?
Jaw Botox is the injection of botulinum toxin Type A into the masseter muscle — the primary muscle responsible for jaw clenching and chewing — to reduce its volume and create a slimmer V-line jawline. At RE:BERRY Incheon Airport, Korean wrinkle Botox starts at ₩9,900 per site (regular ₩40,000), and the Smooth Jawline Package including LENA chin filler 1cc + Korean jawline & chin Botox is ₩160,000.
Masseter Botox is one of the most requested cosmetic procedures in South Korea, where the V-line (V자 턱선) facial contour is a defining beauty standard. The masseter muscle is a powerful, thick jaw muscle that can become hypertrophied from habitual clenching, bruxism (teeth grinding), or genetic predisposition — creating a square, wide jawline. Botulinum toxin Type A works by blocking acetylcholine release at the neuromuscular junction, causing targeted muscle relaxation and subsequent atrophy over 2-4 weeks. Clinical evidence demonstrates that masseter Botox reduces muscle thickness by 20-30% at 3 months post-injection, with visible slimming appearing as early as 2-4 weeks (Kim NH et al., Aesthetic Plast Surg 2010; DOI: 10.1007/s00266-009-9396-5). Beyond cosmetic slimming, masseter Botox provides therapeutic relief for bruxism, TMJ (temporomandibular joint) pain, and tension headaches originating from jaw clenching — making it a dual-purpose treatment popular among stressed travelers. South Korea performs the highest volume of botulinum toxin injections per capita globally, and Korean Botox formulations (such as Nabota/Jeuveau, Botulax, and Meditoxin) are manufactured under strict KFDA pharmaceutical GMP standards. At RE:BERRY Incheon Airport, Dr. Cho Sung-Jun and Dr. Kim Dong-Young perform jaw Botox with precise anatomical knowledge of the masseter’s three layers (superficial, middle, deep) to ensure even distribution and natural-looking slimming without affecting chewing function. The procedure takes just 10-15 minutes with zero downtime — you can fly the same day.

How Jaw Botox Works at RE:BERRY
A quick, precise four-step process for V-line jaw slimming.

Facial Analysis & Consultation
Dr. Cho or Dr. Kim assesses your masseter muscle thickness by palpation during clenching, evaluates facial symmetry, and discusses your aesthetic goals. Photos taken for baseline comparison.

Injection Point Mapping
The doctor maps 3-5 injection points per side across the masseter’s superficial and deep layers. Points are marked to ensure even toxin distribution for natural, symmetrical slimming without affecting the smile or chewing.

Precision Injection
KFDA-approved botulinum toxin (typically 25-50 units per side) is injected using fine 30-32G needles. The entire procedure takes 10-15 minutes. No anesthesia needed — discomfort is minimal (brief pinch sensation).

Aftercare & Follow-Up
No downtime. Avoid massaging the jaw area for 24 hours. Results appear in 2-4 weeks as the muscle gradually slims. Optional follow-up at 2 weeks to assess symmetry.
What to Expect from Jaw Botox
- V-Line Jaw Slimming: Masseter volume reduction of 20-30% creates a slimmer, more V-shaped jawline visible at 2-4 weeks (Kim NH et al., Aesthetic Plast Surg 2010; DOI: 10.1007/s00266-009-9396-5).
- Bruxism Relief: Reduces teeth grinding force by up to 60%, relieving jaw pain, headaches, and dental enamel wear from chronic bruxism.
- TMJ Pain Reduction: Muscle relaxation alleviates temporomandibular joint pain and tension headaches originating from jaw clenching.
- Zero Downtime: 10-15 minute procedure with no swelling, bruising, or recovery time. Fly the same day — ideal for travelers.
- Natural-Looking Results: Gradual slimming over 2-4 weeks means no sudden change — results appear natural, not artificial.
- Long-Lasting: Effects last 4-6 months. With repeat treatments, the masseter may permanently reduce in size over time (Park MY et al., Dermatol Surg 2017; DOI: 10.1097/DSS.0000000000001019).
| Timeline | What to Expect |
|---|---|
| Day 1 | No visible change. Tiny needle marks fade within hours. Resume all normal activities immediately. |
| Week 1-2 | Muscle begins to soften. May notice reduced clenching force. No visible slimming yet. |
| Week 3-4 | Visible jawline slimming begins. Face appears more oval. V-line contour starts to emerge. |
| Month 2 | Peak slimming results. Maximum masseter volume reduction achieved. Jawline is visibly narrower and more defined. |
| Month 3-4 | Results maintained. Muscle volume remains reduced. Bruxism relief continues. |
| Month 4-6 | Gradual return of muscle activity. Maintenance injection recommended at 4-6 months for sustained V-line. |

The Science Behind Jaw Botox
Peer-reviewed research supporting masseter Botox for jaw slimming and bruxism treatment.
Masseter Muscle Anatomy and Hypertrophy
The masseter is one of the four muscles of mastication, consisting of superficial and deep heads. Masseter hypertrophy — enlargement of the muscle beyond normal size — can result from habitual clenching (bruxism), gum chewing, stress-related jaw tension, or genetic predisposition. The condition is particularly common in East Asian populations where the wider mandibular angle combined with a hypertrophied masseter creates a square, wide facial silhouette. Ultrasound studies show that hypertrophied masseters can reach 15-18mm thickness compared to the normal range of 10-12mm (Ryu et al., J Oral Maxillofac Surg 2020; DOI: 10.1016/j.joms.2020.03.029). This thickening is the target of masseter Botox.
Mechanism of Botulinum Toxin in Masseter Reduction
Botulinum toxin Type A (BoNT-A) blocks presynaptic release of acetylcholine at the neuromuscular junction, causing temporary chemical denervation of the injected muscle fibers. In the masseter, this denervation leads to muscle relaxation within 3-7 days, followed by progressive disuse atrophy over 2-8 weeks as the blocked fibers decrease in cross-sectional area. Kim NH et al. (Aesthetic Plast Surg 2010; DOI: 10.1007/s00266-009-9396-5) demonstrated in a prospective study of 45 patients that a single injection of 25 units per side reduced masseter thickness by 22.3% at 3 months and 30.1% at 6 months as measured by ultrasound. Crucially, bite force was reduced by only 18% — meaning patients maintained full chewing function while achieving significant cosmetic slimming.

Bruxism and TMJ Therapeutic Benefits
Beyond cosmetic slimming, masseter Botox provides significant therapeutic benefit for bruxism and TMJ disorders. A meta-analysis by Fernandez-Nunez et al. (J Oral Rehabil 2019; DOI: 10.1111/joor.12798) analyzing 8 RCTs with 282 patients found that BoNT-A injection into the masseter reduced bruxism-related pain scores by 52% and nocturnal clenching events by 44% at 3 months. The treatment also reduces headache frequency in patients with tension-type headaches originating from jaw clenching (mean reduction of 4.2 headache days per month). For travelers experiencing jaw pain from long-haul flights (where stress and cabin pressure can exacerbate clenching), masseter Botox offers dual cosmetic and therapeutic benefit.
Long-Term Effects of Repeated Treatments
Park MY et al. (Dermatol Surg 2017; DOI: 10.1097/DSS.0000000000001019) followed patients receiving repeated masseter Botox over 4+ years and found that consistent treatment every 4-6 months led to progressive, lasting muscle volume reduction even between treatments. After 5 or more sessions, many patients required lower doses and less frequent injections, suggesting semi-permanent structural change in the masseter. This makes jaw Botox not just a temporary fix but a long-term facial contouring strategy.

“I have been grinding my teeth for years and my jaw was getting wider and wider. Dr. Cho not only slimmed my jawline but also completely relieved my TMJ pain. I sleep so much better now.”
“The price difference compared to Japan or Singapore is incredible. ₩9,900 for wrinkle Botox is unbelievable. I also added jaw Botox and the results are exactly what I wanted — a softer, more feminine jawline.”
Frequently Asked Questions About Jaw Botox
Expert answers from RE:BERRY Incheon Airport’s jaw Botox specialists.
Korean wrinkle Botox starts at ₩9,900 per site (regular ₩40,000). The Smooth Jawline Package (LENA chin filler 1cc + Korean jawline & chin Botox) is ₩160,000. Juvederm Chin Filler + Chin Botox is ₩390,000 (regular ₩700,000). All prices exclude VAT.
Typically 25-50 units per side (50-100 units total) depending on masseter muscle size and thickness. Dr. Cho assesses your muscle during consultation and recommends the optimal dosage. Higher units are needed for thicker muscles.
The injection itself takes 10-15 minutes. Including consultation and photos, plan for about 30 minutes total. No anesthesia, no numbing cream needed.
Muscle softening begins at 1-2 weeks. Visible jaw slimming appears at 3-4 weeks. Peak results at 6-8 weeks. The gradual onset means the change looks natural.
Results last 4-6 months. With repeated treatments (3+ sessions), results tend to last longer as the masseter progressively atrophies. Many long-term patients need treatment only every 6-8 months.
No. At proper dosages, jaw Botox reduces masseter volume but preserves full chewing function. Studies show only 18% bite force reduction — well within the normal functional range. You will not notice any difficulty eating.
Yes. There is absolutely zero downtime. You can fly, eat, drink, and resume all normal activities immediately after the procedure. This makes it ideal for travelers at Incheon Airport.
Minimal discomfort. We use fine 30-32G needles. Patients describe a brief pinch sensation lasting 1-2 seconds per injection point. No numbing cream or anesthesia is needed. Most patients are surprised by how painless it is.
Jaw Botox slims the jawline by reducing masseter muscle volume (removing width). Chin filler adds projection and length to the chin point. They complement each other — the Smooth Jawline Package combines both for optimal V-line effect.
Yes. Korean botulinum toxin products (Nabota/Jeuveau, Botulax, Meditoxin) are manufactured under strict KFDA pharmaceutical GMP standards and are FDA-cleared in multiple countries. South Korea performs the highest volume of Botox injections per capita globally. See our Botox page for more details.
Absolutely. Jaw Botox is very popular among male patients — both for V-line aesthetics and for bruxism/TMJ relief. Men typically require higher doses (40-50 units per side) due to larger masseter muscles.
Yes. Masseter Botox reduces clenching force by up to 60%, providing significant relief for bruxism, TMJ pain, and tension headaches. Many patients come initially for cosmetic slimming and discover the therapeutic benefits.
For 24 hours: avoid rubbing or massaging the jaw area, avoid lying flat for 4 hours, avoid strenuous exercise, and avoid excessive alcohol. No other restrictions — eat, drink, and fly normally.
Yes. Popular combinations include jaw Botox + wrinkle Botox (forehead, crow’s feet) in the same session, or jaw Botox + glass skin treatment. Filler and Botox can often be done the same day.
Dr. Cho and Dr. Kim routinely correct jaw asymmetry by injecting different doses on each side. During consultation, they assess your muscle thickness bilaterally and adjust units accordingly for a balanced result.
Yes. The same KFDA-approved botulinum toxin is used for both wrinkle and jaw Botox. The ₩9,900 price is per wrinkle site (forehead line, frown line, etc.). Jaw masseter Botox uses more units and is included in the Smooth Jawline Package at ₩160,000.
RE:BERRY uses a multi-point, multi-layer injection technique targeting both superficial and deep masseter heads for even, natural-looking slimming. Many clinics inject only the superficial layer, which can cause unnatural ‘denting.’ Our doctors inject 3-5 points per side for smooth results.
Our doctors carefully calibrate dosage to your facial proportions. The goal is a harmonious V-line, not an excessively narrow face. If this is a concern, a lower initial dose can be used with a follow-up touch-up at 2 weeks.
It includes LENA chin filler 1cc + Korean jawline Botox + chin Botox for ₩160,000 (total). The chin filler adds forward projection while the Botox slims the lateral jaw — creating a comprehensive V-line effect.
