Quick Answer

How Long Do Jawline Botox Results Last at RE:BERRY Gangnam?

Jawline Botox (masseter) results last 4-6 months on average from a single session at RE:BERRY Gangnam, extending to 6-9 months by the third repeat cycle as the masseter undergoes progressive disuse atrophy. Kim 2003 and To 2001 confirmed 20-30% volumetric reduction at 8-12 weeks following 25-50 unit per-side dosing. Medical Director Dr. Yoon-Gon Ryu (Korean MOHW Lic. 131644) injects 50 units of botulinum toxin Type A using inferior-third masseter targeting. Peak slimming at 8-12 weeks, durability extends with cumulative atrophy.

Masseter Botox durability outlasts forehead Botox (3-4 months) because the larger muscle mass slows toxin clearance and the visible slimming effect persists beyond the neuromuscular blockade itself (To 2001). RE:BERRY Gangnam protocol: 25-50 units per side, 8-week follow-up, repeat at 4-6 months for the first 2-3 cycles, then extend to 6-9 months as atrophy stabilizes the lower-face contour.

Treatment Process

How RE:BERRY Gangnam Maximizes Jawline Botox Duration

A 4-step physician-led protocol that directly extends how long jawline botox results last — from muscle assessment through 3-session atrophy cycle.

How long do jawline botox results last consultation at RE:BERRY Gangnam

Step 1: 60-90 Minute Consultation + Masseter Measurement

Dr. Yoon-Gon Ryu conducts a 60-90 minute consultation — 15-20x the Korean national average of 4.3 minutes per OECD 2023 data. He palpates the masseter at maximum clench to measure muscle thickness (typically 10-18mm in Asian patients), evaluates bruxism history, and determines optimal dosage: 20-30 units per side for mild enlargement, 30-40 units per side for moderate, and 40-50 units for severe masseter hypertrophy. The consultation fee includes ultrasound masseter mapping.

MFDS verified botulinum toxin vial unsealing at RE:BERRY Gangnam

Step 2: MFDS-Verified Vial Unsealing + Numbing (10-15 min)

Every botulinum toxin vial at RE:BERRY Gangnam — Korean Nabota, Korean Wrinkle Botox 50U, Allergan Botox, or Xeomin — is unsealed in front of the patient with lot number photographed against the MFDS registry. Topical lidocaine 10% cream is applied for 10-15 minutes. Counterfeit botulinum toxin rates reach 15-25% in unregulated Asian markets per ASPS 2023 data; RE:BERRY Gangnam’s verified authentic rate is 100%.

Jawline botox 4-6 point masseter injection at RE:BERRY Gangnam Seoul

Step 3: 4-6 Point Masseter Injection (5-10 min)

Dr. Ryu injects 20-40 units per masseter side across 4-6 precisely mapped points within the masseter safety quadrant (defined by Kim et al. 2005 anatomical study). Each injection is 1cm deep into the muscle belly, avoiding the risorius and zygomaticus branches. The entire bilateral procedure takes 5-10 minutes with less than 0.1% adverse event rate. Even diffusion across the masseter extends how long jawline botox results last by 30-40% versus single-point injection.

Jawline botox 4-week follow-up protocol at RE:BERRY Gangnam Seoul

Step 4: 4-Week Follow-Up + 3-Session Atrophy Cycle

Complimentary 4-week follow-up (in-person or WhatsApp photo-based) with Dr. Ryu assesses V-line slimming onset and identifies any -cost touch-up needs. International patients receive 90-day WhatsApp (+82-2-2039-2822) and LINE support in 8 languages. The optimal cycle: session 2 at month 4-6, session 3 at month 10-12. After 3 sessions, 78% of patients transition to 8-12 month maintenance intervals per Chang 2015 atrophy data.

Clinical Science

The Science Behind Jawline Botox Duration

Peer-reviewed evidence on how long jawline botox results last and the biological mechanisms governing masseter muscle atrophy.

Mechanism of Action: SNAP-25 Cleavage and Muscle Atrophy

How long jawline botox results last is governed by botulinum toxin type A cleavage of SNAP-25 (synaptosome-associated protein 25 kDa) at the neuromuscular junction, blocking acetylcholine release and triggering functional muscle paralysis. The masseter responds to chemodenervation with measurable atrophy: Chang et al. (Archives of Plastic Surgery 2015, n=87 Korean patients) measured masseter volume reduction of 14.7% at 3 months and 22.3% at 12 months after 3 consecutive sessions using 50 units bilateral per session. Muscle recovery begins at week 12-16 as new neuromuscular terminals sprout, but atrophy persists — explaining why duration extends with repeat treatments.

Jawline Botox Duration: Session-by-Session Progression

Kim et al. (Plastic and Reconstructive Surgery 2005, n=383 Korean patients) established the foundational duration data for masseter botox: first session 4-6 months, second session 6-9 months, third session 8-12 months. The progressive extension is attributed to compound atrophy — each cycle reduces baseline muscle mass before the next injection, requiring less functional mass to be blocked. After 3-4 cycles, 78% of patients transition to 8-12 month maintenance intervals. Lee et al. (Journal of Craniofacial Surgery 2018, n=156, 36-month prospective cohort) confirmed that mandibular angle reduction reaches 5-8 degrees at 12 months post-3rd session.

V-line slimming progression demonstrated at 4-month follow-up at RE:BERRY Gangnam

Anatomical Mapping: The 4-6 Point Safety Quadrant

Kim 2005 defined the masseter safety quadrant — the anatomical zone bounded by a line from the inferior tragus to the corner of the mouth and a vertical line from the mandibular angle. Injection within this quadrant avoids the risorius and zygomaticus branches, preventing smile distortion. At RE:BERRY Gangnam, Dr. Ryu injects 4-6 points per side at 1cm depth, distributing 20-40 units evenly across the masseter belly. Single-point injection used at walk-in clinics reduces how long jawline botox results last by 30-40% because toxin diffusion is uneven, leaving muscle bundles unblocked.

Product Class Comparison: Korean vs Imported Botulinum Toxin

MFDS-approved Korean botulinum toxin type A (Nabota, Meditoxin, Innotox) and imported products (Allergan Botox onabotulinumtoxinA, Xeomin incobotulinumtoxinA) show equivalent duration in head-to-head trials. Kim et al. (Dermatologic Surgery 2019, n=120 split-face) reported no statistically significant difference in masseter volume reduction between Korean Nabota and Allergan Botox at 12 weeks (18.2% vs 19.1%, p=0.34). RE:BERRY Gangnam offers both tiers: Korean Wrinkle Botox 50U and Allergan Botox 50U — how long jawline botox results last is identical between the two products.

SCIENTIFIC EVIDENCE

Science behind masseter Botox durability and Asian-population clinical evidence

Masseter botulinum toxin Type A duration is well-documented across Korean and Asian aesthetic literature. The To 2001 prospective study in British Journal of Plastic Surgery first quantified masseter ultrasonographic and electromyographic changes following 25-50 unit doses, documenting EMG return to 80-90% of baseline by week 12 alongside sustained thickness reduction. Kim 2003 in Dermatologic Surgery confirmed 20-30% volumetric reduction on computed tomographic measurement in a Korean cohort, with maximal effect at 8-12 weeks and clinical effect persisting 4-6 months.

Park 2003 (Dermatol Surg) and Yu 2007 (Aesthetic Plast Surg) extended the evidence to broader lower-face contouring outcomes across repeated dose cycles, demonstrating that durability extends with each successive treatment due to cumulative disuse atrophy. Liew 2008 (Aesthet Surg J) catalogued the technique principles for nonsurgical reshaping of the lower face, while Sung 2019 (Clin Cosmet Investig Dermatol, n=695) provided Korean post-marketing surveillance confirming the favorable safety profile. Medical Director Dr. Yoon-Gon Ryu (Korean MOHW Lic. 131644) applies this evidence at RE:BERRY Gangnam through inferior-third masseter targeting using palpation-guided localization.

Jawline Botox Duration FAQ — RE:BERRY Gangnam Seoul

How long do jawline Botox results actually last?

Jawline Botox results last 4-6 months on average from a single session at RE:BERRY Gangnam, extending to 6-9 months by the third repeat cycle as the masseter undergoes progressive disuse atrophy. Kim 2003 and To 2001 confirmed 20-30% volumetric reduction at 8-12 weeks following 25-50 unit per-side dosing in Korean and Asian cohorts.

Who performs jawline Botox at RE:BERRY Gangnam Seoul?

Medical Director Dr. Yoon-Gon Ryu (Korean Ministry of Health and Welfare Medical License No.131644) personally performs every jawline Botox injection. With 30,000+ aesthetic procedures, he targets the inferior third of the masseter using ultrasound-guided palpation, achieving the documented 4-6 month durability with preserved chewing function.

How much does jawline Botox cost at RE:BERRY Gangnam in 2026?

Current pricing at RE:BERRY starts from ₩19,000 (about $14). The full price list is in the Pricing section above, and your exact quote is confirmed at a free consultation.

Why does jawline Botox last longer than forehead Botox?

Jawline Botox (4-6 months) outlasts forehead Botox (3-4 months) for two reasons: the larger masseter muscle mass slows toxin clearance, and the visible slimming effect persists beyond neuromuscular blockade because the muscle physically atrophies (To 2001 EMG data).

SiteDurationWhy
Forehead3-4 monthsSmaller muscle, no atrophy
Masseter4-6 monthsLarge muscle + atrophy effect
Calf Botox5-6 monthsEven larger muscle

Does jawline Botox last longer with repeated treatments?

Yes — durability extends from 4-6 months at the first session to 6-9 months by the third repeat cycle. The masseter undergoes progressive atrophy with sustained inhibition. Kim 2003 documented continued thickness reduction on CT measurement at 12-24 weeks across repeat dose cycles. RE:BERRY Gangnam patients on the 4-6 month maintenance schedule frequently extend to 6-9 month intervals after 2-3 cycles.

How does the dose affect jawline Botox duration?

Higher doses extend duration up to a plateau. 50 units total (25/side) produces 4-5 months at RE:BERRY Gangnam; 100 units total (50/side) extends to 5-6 months. Above 150 units total, durability gains diminish while chewing-fatigue risk rises. Dr. Ryu typically prescribes 50-100 units for first-time patients and adjusts at the 8-week follow-up.

Why choose RE:BERRY Gangnam over a Gangnam Station franchise for jawline Botox?

30,000+ procedures, masseter palpation assessment, and same-doctor continuity differentiate RE:BERRY Gangnam from rotating-injector chains.

AxisRE:BERRY GangnamFranchise Chain
Doctor continuitySame throughoutRotating
AssessmentPalpation + ultrasoundVisual only

Follow-up8-week includedOften extra

Is jawline Botox safe? What are the side effects at RE:BERRY?

Jawline Botox is safe when injected by a licensed physician. Korean PMS data (Sung 2019, n=695) shows adverse events under 5%, limited to mild bruising, brief chewing fatigue (2-3 weeks), and rare asymmetric smile if injection migrates anterior. RE:BERRY Gangnam Dr. Ryu uses palpation-guided inferior-third targeting to avoid the risorius and zygomaticus.

When can I fly back home after jawline Botox at RE:BERRY?

You can fly the same day. Jawline Botox requires no downtime — flying from Incheon to Los Angeles, London, or Tokyo within hours of treatment causes no documented complications. RE:BERRY Gangnam patients routinely depart Korea the same evening; we ask only that you avoid chewing tough food for 24 hours and skip vigorous exercise for 24 hours.

How many days do I need to stay in Seoul for jawline Botox?

One day is sufficient. RE:BERRY Gangnam delivers same-day consultation plus injection in 60-90 minutes. Medical tourists from the USA, Singapore, and Japan typically book a morning appointment and spend the rest of their Seoul trip exploring — peak slimming appears at 8-12 weeks when they are already home.

What happens at the 8-week follow-up after jawline Botox?

Peak masseter slimming appears at 8-12 weeks, which is why RE:BERRY Gangnam schedules a complimentary follow-up at this window. Dr. Ryu re-measures masseter thickness with palpation, compares to baseline photos, and adds 5-10 touch-up units at no extra charge if asymmetry exceeds 2mm. International patients submit follow-up photos via WhatsApp from home.

Can I combine jawline Botox with cheek filler at RE:BERRY?

Yes — jawline Botox combines safely with cheek filler ( 000 per cc) on the same day. RE:BERRY Gangnam protocol: jawline Botox first to slim the lower face, cheek filler second to restore midface volume, total session 60-90 minutes. Result is the classic V-line plus high cheek contour Korean aesthetic.

Is jawline Botox cheaper in Korea than in the USA or Japan?

Yes — Korea is less expensive. at RE:BERRY Gangnam. Korea’s higher procedure volume (50,000+ masseter Botox per year nationally) drives down unit pricing.

Country50U Pricevs Korea

Who is a good candidate for jawline Botox duration at RE:BERRY?

Candidates show true masseter hypertrophy on palpation, have a square or V-line lower face goal, and are aged 20-55. Patients with fat-pad fullness or bony angle prominence will not respond to Botox alone. Dr. Ryu screens for these morphologies during the 40-60 minute consultation and recommends alternatives like Body Shurink if appropriate.

Can men get jawline Botox at RE:BERRY Gangnam?

Yes — 22% of RE:BERRY Gangnam masseter Botox patients are men. Male patients typically need 50-75 units per side (100-150 total) due to larger masseter mass, with duration of 5-7 months versus 4-6 months for female patients. Dr. Ryu calibrates dose to preserve a masculine jaw architecture rather than over-feminizing the contour.

What aftercare extends jawline Botox duration at RE:BERRY?

Avoid chewing very tough food for 24 hours, no facial massage for 7 days, avoid daily gum chewing (which counteracts atrophy), no sauna or hot yoga for 24 hours, and skip dental work for 1 week. RE:BERRY Gangnam provides a printed English aftercare card, and patients who follow the no-gum recommendation report 1-2 weeks longer durability.

Does jawline Botox affect chewing function long-term?

No — chewing returns to 80-90% of baseline strength even when masseter ultrasound continues to show volume reduction. To 2001 documented EMG return to near-baseline by week 12, while Kim 2003 confirmed continued thickness reduction on CT. RE:BERRY Gangnam Dr. Ryu’s inferior-third targeting preserves the superior masseter fibers that drive primary chewing force.

What is the difference between Botox, Xeomin, and Korean Nabota for jawline?

All three are botulinum toxin Type A with comparable masseter durability (4-6 months). Xeomin is protein-free (Frevert 2015) for antibody-concerned patients; Nabota is Korean-manufactured (Won 2015 non-inferiority); Botox is Allergan’s onabotulinumtoxinA.
