Jawline Botox in Korea — V-Line Slimming at RE:BERRY
Korea is the world capital of jawline Botox — where the V-line (V자 턱선) facial contour defines modern beauty. At RE:BERRY Incheon Airport, KFDA-approved botulinum toxin precisely targets the masseter muscle to slim a square jaw into a tapered V-line without surgery, scars, or downtime. Korean wrinkle Botox from ₩9,900/site. Smooth Jawline Package ₩160,000. Open 365 days near ICN airport.
What Is Jawline Botox and Why Is Korea the Best Place to Get It?
Jawline Botox is the injection of botulinum toxin Type A into the masseter muscle — the powerful jaw-clenching muscle — to reduce its volume and transform a wide, square jawline into a slimmer V-line contour. South Korea performs more jawline Botox procedures per capita than any other country, making it the global epicenter of this technique. At RE:BERRY Incheon Airport, Korean wrinkle Botox starts at ₩9,900/site (regular ₩40,000) and the Smooth Jawline Package is ₩160,000.
The V-line (V자 턱선) is a defining beauty standard in Korea, Japan, China, and increasingly worldwide — a tapered jawline that creates an inverted triangle from cheekbones to chin. Masseter hypertrophy (enlarged jaw muscle) is the most common cause of a square or wide jawline, affecting an estimated 40-60% of East Asian populations due to dietary habits, bruxism, and genetic factors. Botulinum toxin Type A works by blocking acetylcholine release at the neuromuscular junction, causing targeted muscle relaxation and subsequent atrophy. Clinical studies demonstrate that masseter Botox reduces muscle thickness by 20-30% at 3 months post-injection, with visible V-line slimming appearing within 2-4 weeks (Kim NH et al., Aesthetic Plast Surg 2010; DOI: 10.1007/s00266-009-9396-5). Korea’s dominance in this field stems from three factors: (1) the highest botulinum toxin injection volume per capita globally, giving Korean physicians unmatched experience; (2) multiple KFDA-approved Korean botulinum toxin products (Nabota/Jeuveau, Botulax, Meditoxin) manufactured under strict pharmaceutical GMP standards, creating competitive pricing; and (3) decades of refined injection techniques optimized for Asian facial anatomy. At RE:BERRY Incheon Airport, Dr. Cho Sung-Jun and Dr. Kim Dong-Young perform jawline Botox with precise knowledge of the masseter’s three layers (superficial, middle, deep) for even distribution and natural-looking V-line slimming. Beyond cosmetic contouring, jawline Botox provides therapeutic relief for bruxism (teeth grinding), TMJ pain, and tension headaches — making it a dual-purpose treatment especially popular among stressed travelers. The procedure takes 10-15 minutes with zero downtime — fly the same day.

How Jawline Botox Works at RE:BERRY Korea
Physician-led four-step process for natural V-line jawline slimming.
Jaw Assessment & V-Line Planning
Dr. Cho evaluates your masseter muscle thickness by palpation during clenching, measures jaw width, assesses facial proportion (bigonial width-to-bizygomatic width ratio), and identifies any TMJ issues. Your personalized injection plan includes the number of units, injection depth, and expected V-line slimming timeline.
Injection Point Mapping
3-5 injection points per side are mapped on the masseter muscle. Each point targets a different layer of the muscle (superficial, middle, deep) for even atrophy and natural-looking slimming. This multi-point technique prevents localized over-atrophy that can create uneven results.
KFDA-Approved Botox Injection
KFDA-approved botulinum toxin Type A is injected using 30G ultra-fine needles into the mapped points. Dr. Cho distributes the toxin evenly across all three masseter layers. The entire injection process takes 5-10 minutes. No anesthesia required — the needles are virtually painless.
Zero Downtime Aftercare
No downtime whatsoever. Avoid rubbing or massaging the jaw for 4 hours. No lying flat for 4 hours. No saunas or hot yoga for 24 hours. You can eat, drink, fly, and resume all normal activities immediately. Results develop gradually over 2-6 weeks as the masseter atrophies.

The Science Behind Jawline Botox for V-Line Slimming
Peer-reviewed evidence supporting masseter Botox for jawline contouring and the Korean technique advantage.
Masseter Muscle Anatomy and Hypertrophy
The masseter is a paired rectangular muscle consisting of three layers: superficial, middle, and deep. It is the primary elevator of the mandible, generating bite forces up to 70 kg. Masseter hypertrophy — abnormal enlargement of this muscle — is the most common cause of a wide, square jawline. Prevalence is higher in East Asian populations (estimated 40-60%) due to dietary habits (chewing tougher foods), parafunctional habits (bruxism, gum chewing), and genetic predisposition. Botulinum toxin Type A blocks presynaptic acetylcholine release at the neuromuscular junction, causing dose-dependent muscle relaxation and subsequent disuse atrophy (Carruthers & Carruthers, Dermatol Surg 2004; DOI: 10.1111/j.1524-4725.2004.30550.x).
Clinical Evidence for Masseter Botox
Kim NH et al. (2010) conducted a prospective study of 45 patients receiving masseter Botox for jawline contouring. Ultrasonographic measurements demonstrated a mean 21.3% reduction in masseter thickness at 12 weeks, with 93% of patients reporting satisfaction with jawline slimming. Importantly, none reported significant chewing difficulty (DOI: 10.1007/s00266-009-9396-5). A larger systematic review by Ahn et al. (2019) analyzing 23 studies and 1,400+ patients confirmed consistent masseter volume reduction of 15-30% at 3-6 months, with adverse events limited to mild injection-site discomfort and temporary chewing fatigue (DOI: 10.1007/s00266-018-1298-7).
Korean Botulinum Toxin Products: KFDA Standards
Korea manufactures several KFDA-approved botulinum toxin Type A products: Nabota (Daewoong Pharmaceutical, also marketed as Jeuveau in the US), Botulax (Hugel), and Meditoxin (Medytox). These products undergo the same rigorous purification and potency testing as Allergan’s Botox. Yoon et al. (2020) demonstrated bioequivalence between Nabota and Botox in a double-blind randomized trial of 270 subjects, with no clinically significant differences in efficacy, onset, duration, or safety (DOI: 10.1111/dsu.14454). Korean botulinum products cost 30-50% less than imported Botox due to domestic manufacturing, enabling Korean clinics to offer competitive pricing without compromising product quality.
The Korean Multi-Layer Injection Technique
Korean physicians have refined the masseter Botox technique beyond simple intramuscular injection. The multi-layer approach distributes botulinum toxin across the superficial, middle, and deep masseter layers using 3-5 injection points per side. This prevents localized over-atrophy (which can create visible indentations) and ensures uniform muscle volume reduction. Lee et al. (2018) showed that multi-layer injection produced 27% more uniform thickness reduction compared to single-point injection, with significantly higher patient satisfaction scores (DOI: 10.1007/s00266-018-1152-y).

What Patients Say About Jawline Botox in Korea
“I flew from Tokyo specifically for jawline Botox at RE:BERRY. Korean pricing is unbeatable — ₩160,000 for the Smooth Jawline Package versus ¥80,000+ in Japan. Six weeks later, my jawline is noticeably slimmer.”
“Dr. Cho explained the three-layer injection technique and why it matters for even results. I had jaw Botox before in Singapore with a single deep injection and the result was uneven. This time it is perfectly symmetrical.”
“I have bruxism and a wide jaw — the Botox solved both. I stopped grinding my teeth within a week and my face looks slimmer at 6 weeks. Got it done during a layover at Incheon. Zero downtime.”
Frequently Asked Questions About Jawline Botox in Korea
Expert answers about jawline Botox, V-line slimming, masseter reduction, and treatment in Korea.
Jawline Botox at RE:BERRY Incheon Airport: Korean wrinkle Botox from ₩9,900/site (regular ₩40,000). Smooth Jawline Package (LENA chin filler 1cc + jawline Botox) ₩160,000. Juvederm chin filler + Korean chin Botox ₩390,000. All prices exclude 10% VAT.
Muscle relaxation begins at 1-2 weeks. Initial V-line slimming visible at 2-4 weeks. Peak results at 6-8 weeks when masseter thickness reduces by 20-30%. The gradual change appears natural.
Yes. Korean botulinum toxin is manufactured under KFDA pharmaceutical GMP standards. Clinical trials demonstrate bioequivalence with Allergan Botox (Yoon et al., 2020; DOI: 10.1111/dsu.14454). All injections at RE:BERRY are performed by licensed physicians.
At therapeutic doses for V-line slimming, jawline Botox does not significantly impair chewing function. You may notice mild fatigue when chewing tough foods for the first 1-2 weeks. This resolves as your jaw adapts. Kim NH et al. (2010) reported zero patients with significant chewing difficulty.
Typical dosage is 25-50 units per side (50-100 units total), depending on masseter thickness and desired slimming. Dr. Cho assesses your muscle size during consultation and recommends the optimal dose.
Yes, and this is our most popular combination. The Smooth Jawline Package (₩160,000) includes LENA chin filler 1cc + jawline Botox. The filler projects the chin while the Botox slims the jaw — creating a complete V-line effect.
Results last 4-6 months. With repeated treatments (every 4-6 months), duration tends to extend as the masseter remains in a partially atrophied state. Some patients eventually need treatment only once a year.
Korean botulinum toxin products (Nabota, Botulax, Meditoxin) use the same active ingredient — botulinum toxin Type A — as Allergan Botox. Double-blind clinical trials confirm bioequivalence in efficacy, onset, and safety. The main difference is pricing: Korean products cost 30-50% less due to domestic manufacturing.
Yes, immediately. There is zero downtime. Cabin pressure does not affect Botox. Avoid rubbing your jaw and lying flat for 4 hours. RE:BERRY is minutes from Incheon International Airport for maximum convenience.
Minimal discomfort. We use 30G ultra-fine needles and the injection takes only 5-10 minutes. Most patients describe a slight pinch. No topical anesthesia is required, though we can apply numbing cream upon request.
They are the same procedure. ‘Jawline Botox’ and ‘masseter Botox‘ both refer to botulinum toxin injection into the masseter muscle for jaw slimming. ‘V-line Botox’ is another common name for the same treatment.
Yes. Male jawline Botox is increasingly popular. The technique is adjusted for masculine facial proportions — creating a slimmer but still angular jawline rather than an extremely narrow V-line. Many male patients seek jawline Botox primarily for bruxism relief.
Jawline Botox is temporary and reversible — the muscle returns to its original size within 4-6 months as the Botox wears off. There is no permanent change. If you are satisfied, maintain results with follow-up injections.
Korean jawline Botox costs 50-70% less than Japan or Singapore with equivalent or superior technique. Korean physicians perform the highest volume of this procedure globally. RE:BERRY’s Smooth Jawline Package (₩160,000 / $120 USD) would cost $500-$800 in Singapore or ¥80,000-¥120,000 in Tokyo.
A follow-up is recommended at 4-6 weeks to assess results but is not mandatory. If you are a traveler, Dr. Cho provides a thorough assessment during the initial visit and offers virtual follow-up via KakaoTalk or WhatsApp photos.
The Smooth Jawline Package (₩160,000) combines LENA chin filler 1cc + Korean jawline & chin Botox. The filler adds chin projection for V-line shaping from below while the Botox slims the jaw from the sides — a comprehensive approach.
Yes. Jawline Botox is an established treatment for TMJ (temporomandibular joint) disorder caused by masseter hyperactivity. It reduces jaw clenching force, relieving TMJ pain, headaches, and tooth wear. Many patients report significant pain relief within 1-2 weeks.
Contraindications include pregnancy, breastfeeding, neuromuscular disorders (myasthenia gravis, Lambert-Eaton syndrome), allergy to botulinum toxin, and active infection at the injection site. Dr. Cho screens for all contraindications during consultation.
Jawline Botox is non-surgical, zero-downtime, reversible, and targets the masseter muscle. Jaw surgery (mandibular angle reduction) permanently removes bone and requires general anesthesia, hospitalization, and 2-4 weeks recovery. Botox is ideal for muscle-based jaw width; surgery is needed for bone-based jaw width.
