Medical Director Dr. Yoon-Gon Ryu performs every jawline Botox injection with anatomical mapping and dose calibration tailored to your facial structure. Masseter Botox 50U at our Gangnam Station clinic, open 365 days with 8-language support for international patients seeking jawline slimming in Seoul.
What Is Jawline Botox in Seoul at RE:BERRY Gangnam?
Jawline Botox in Seoul at RE:BERRY Gangnam uses 50-100 units of botulinum toxin injected into the masseter muscles to slim a square jaw into a V-line contour, costing for 50U with visible slimming results in 4-6 weeks and effects lasting 4-6 months.
Jawline Botox in Seoul has become one of the most requested non-surgical facial contouring procedures for both Korean residents and international visitors. At RE:BERRY Gangnam, jawline Botox targets the masseter muscles — the powerful chewing muscles that create a square or wide lower face appearance when hypertrophied. By injecting precise doses of botulinum toxin (50-100 units depending on muscle mass), Dr. Yoon-Gon Ryu induces controlled muscle atrophy that gradually slims the jawline over 4-6 weeks without surgery, incisions, or significant downtime. The procedure takes only 10-15 minutes and requires no anesthesia in most cases. Jawline Botox in Seoul is particularly popular among patients from East and Southeast Asia where a smaller, V-shaped lower face is considered aesthetically ideal. RE:BERRY Gangnam’s approach to jawline Botox incorporates bilateral symmetry assessment, bite force evaluation, and customized injection point mapping to ensure natural-looking results that preserve normal chewing function. For patients seeking additional jaw definition, jawline Botox can be combined with chin fillers or V-line lifting treatments for a comprehensive facial contouring outcome.

How Jawline Botox in Seoul Works at RE:BERRY Gangnam
A precise four-step jawline Botox protocol designed for optimal V-line contouring with natural results.
Facial Structure Analysis & Masseter Assessment
Your jawline Botox in Seoul begins with a comprehensive facial assessment by Dr. Yoon-Gon Ryu. The doctor evaluates masseter muscle thickness through manual palpation during clenching, measures bilateral jaw width, assesses facial symmetry ratios (bizygomatic versus bigonial width), and identifies any temporomandibular joint (TMJ) issues that could affect treatment planning. This 10-15 minute diagnostic phase determines the optimal unit count (50-100U per side), injection depth, and injection point distribution for your specific anatomy. Patients with bruxism (teeth grinding) benefit from both cosmetic jawline slimming and therapeutic muscle relaxation through the same jawline Botox procedure.
Injection Point Mapping & Preparation
Dr. Ryu marks 3-5 precise injection points per side on the masseter muscle belly using anatomical landmarks. The injection sites are chosen to target the thickest portion of the muscle (typically the mid-belly and inferior portion) while avoiding the parotid gland, facial nerve branches, and the masseter’s anterior border. This careful mapping ensures jawline Botox produces a smooth, natural taper rather than an irregular contour. Ice or topical numbing may be applied for patient comfort, though most patients tolerate jawline Botox in Seoul without anesthesia due to the use of ultra-fine 30-32 gauge needles.
Precision Botulinum Toxin Injection
The core of jawline Botox in Seoul involves injecting botulinum toxin directly into the masseter muscle at the mapped points. At RE:BERRY Gangnam, Dr. Yoon-Gon Ryu uses a controlled micro-injection technique, depositing 8-12 units per injection point across 3-5 sites per side. The total dose ranges from 25-50 units per side (50-100U total) depending on muscle mass. Each injection takes 3-5 seconds. The entire jawline Botox procedure is completed in 10-15 minutes. Dr. Ryu applies gentle pressure post-injection to distribute the toxin evenly within the muscle belly and minimize bruising risk. Patients remain seated for 5 minutes after completion for observation.
Post-Treatment Guidelines & Follow-Up
After jawline Botox in Seoul, patients receive detailed aftercare instructions in their preferred language. Key guidelines include: avoid massaging or pressing the jaw area for 4 hours, remain upright for 4 hours post-injection, avoid strenuous exercise for 24 hours, and refrain from alcohol for 24 hours. A 4-6 week follow-up assessment is recommended to evaluate initial muscle reduction and determine if a touch-up is needed. Most patients notice their jaw starting to slim at week 2-3, with maximum V-line effect at week 6-8. RE:BERRY Gangnam provides WhatsApp, LINE, and KakaoTalk support for post-treatment questions in 8 languages.
What to Expect from Jawline Botox in Seoul at RE:BERRY Gangnam
- Non-Surgical V-Line Contouring: Jawline Botox achieves jaw slimming results comparable to surgical jaw reduction (mandible angle reduction) without general anesthesia, bone cutting, 2-week recovery, or surgical risks.
- 10-Minute Lunchtime Procedure: The entire jawline Botox session takes 10-15 minutes. No downtime, no bandages, no swelling. Patients return to work, sightseeing, or travel immediately after treatment at RE:BERRY Gangnam.
- Dual Cosmetic + Therapeutic Benefit: Jawline Botox simultaneously provides V-line facial slimming and relief from bruxism (teeth grinding), TMJ pain, and tension headaches caused by masseter hypertrophy — 2 benefits in 1 treatment.
- Progressive Natural Results: Results develop gradually over 4-6 weeks as the masseter muscle atrophies, creating a natural-looking transition rather than a sudden change that looks artificial to friends and colleagues.
- Fully Reversible: Unlike surgical jaw reduction, jawline Botox effects are temporary (4-6 months). If you dislike the result — which is extremely rare — your jaw naturally returns to its original shape. Zero permanent risk.
- Safe for All Ethnicities: Jawline Botox in Seoul works equally well on all facial structures and skin types. RE:BERRY Gangnam treats patients from East Asia, Southeast Asia, Middle East, Europe, and the Americas with consistently excellent outcomes.
| Timeline | What to Expect |
|---|---|
| Day 1-3 | Minor tenderness at injection sites resolving within 24-48 hours. No visible changes yet. Normal chewing function preserved — you may notice slightly reduced bite force during hard foods. |
| Week 1-2 | Botulinum toxin begins blocking acetylcholine release at the neuromuscular junction. Masseter muscle contraction weakens. Early reduction in teeth-grinding intensity if bruxism is present. |
| Week 3-4 | Visible jawline slimming begins. The lower face appears narrower. Friends and colleagues may comment that your face looks slimmer or more defined. Muscle volume reduced by 15-20%. |
| Week 5-8 | Maximum V-line contouring effect achieved. Masseter muscle volume reduced by 30-40% from baseline. Jawline transitions from square to oval or heart-shaped. Best time for follow-up photos. |
| Month 3-4 | Results remain stable at peak effect. Some patients begin noticing very gradual muscle recovery. Bruxism relief continues throughout this period. |
| Month 5-6 | Gradual return of muscle volume. Most patients schedule their maintenance jawline Botox session at month 4-5. With consistent treatment (3-4 sessions annually), many patients achieve semi-permanent slimming as the muscle learns to stay smaller. |

The Science Behind Jawline Botox in Seoul
Peer-reviewed evidence supporting botulinum toxin for masseter reduction and jawline contouring.
Masseter Muscle Hypertrophy and Facial Width
Masseter hypertrophy — the enlargement of the jaw-closing muscles — is the primary cause of a wide or square lower face in the absence of bony mandibular prominence. This condition is particularly prevalent in East Asian populations, with studies reporting prevalence rates of 18-25% in Korean and Japanese adults. The masseter is a powerful muscle generating up to 90 kg of bite force, and its enlargement can result from habitual clenching, bruxism, gum chewing, or genetic predisposition. Jawline Botox in Seoul directly targets this muscular component by inducing controlled denervation atrophy through botulinum toxin type A injection.
Mechanism of Botulinum Toxin in Masseter Reduction
Botulinum toxin type A blocks acetylcholine release at the neuromuscular junction, preventing muscle contraction. When injected into the masseter, this biochemical blockade causes progressive disuse atrophy of the muscle fibers over 4-8 weeks. A pivotal study by Kim et al. (2003) demonstrated that a single injection of 25 units per side into the masseter reduced muscle thickness by 31% at 3 months as measured by ultrasonography. The study confirmed that jawline Botox produces reliable, measurable volume reduction without affecting other muscles of mastication, preserving normal eating and speaking function. This mechanism underpins the effectiveness of jawline Botox in Seoul and globally.
Long-Term Efficacy and Cumulative Benefits
Repeated jawline Botox treatments produce cumulative and increasingly durable results. To et al. (2001) conducted one of the earliest controlled studies showing that botulinum toxin injection into the masseter achieved clinically significant jaw narrowing in 94% of patients at the 6-week follow-up. Subsequent research by Xie et al. (2014) using 3D facial scanning quantified that patients receiving 3 or more consecutive jawline Botox sessions (every 4-6 months) achieved a mean bigonial width reduction of 8.2mm — a reduction that partially persisted even 12 months after the last injection, suggesting structural muscle remodeling with consistent treatment.
Safety Profile and Anatomical Considerations
Jawline Botox in Seoul has an excellent safety profile when performed by experienced physicians with thorough anatomical knowledge. The masseter is a superficial muscle with predictable boundaries, making it one of the safest targets for botulinum toxin injection. Critical structures to avoid include the parotid duct (Stensen’s duct), the facial nerve marginal mandibular branch, and the buccal fat pad. At RE:BERRY Gangnam, Dr. Yoon-Gon Ryu uses anatomical landmark-guided injection rather than blind techniques, ensuring consistent results with minimal complication risk. The most common side effects — transient tenderness at injection sites and temporary bite weakness with hard foods — resolve within 1-2 weeks.
