How Long Do Jawline Botox Results Last at RE:BERRY Incheon Airport?
Jawline botox results last 4-6 months after a single treatment of 50 units (₩29,000) at RE:BERRY Incheon Airport, with repeat treatments every 4-6 months gradually extending duration to 6-9 months as the masseter muscle atrophies from consistent neuromodulator exposure over 2-3 sessions.
How long jawline botox results last depends on several interconnected factors — dosage, individual metabolism, masseter muscle thickness, and whether you maintain consistent treatment intervals. At RE:BERRY Incheon Airport, Dr. Cho Sung-Jun, Aesthetic Medicine Specialist, evaluates each patient’s masseter muscle volume using palpation and visual assessment to determine the optimal botulinum toxin dosage for maximum jawline botox duration. The standard protocol begins with 50 units of Korean wrinkle botox per side, targeting the superficial and deep layers of the masseter muscle. Most patients notice initial jawline slimming within 2-4 weeks as the muscle fibers begin to relax and atrophy. Peak results — the most dramatic V-line effect — appear at 6-8 weeks post-injection. For first-time patients, jawline botox slimming effects typically last 4-6 months before the masseter muscle gradually regains its original activity. However, patients who complete 3 consecutive treatments at regular intervals often experience extended results lasting 6-9 months because repeated neuromodulator exposure causes progressive muscle atrophy. RE:BERRY’s jawline botox program includes a personalized maintenance schedule designed to maximize how long results last while minimizing total units needed over time. The clinic operates 365 days a year with complimentary airport pickup from ICN Terminal 1, making it easy for international patients to maintain their jawline botox treatment schedule during repeat visits to Korea.
How Jawline Botox Works for Long-Lasting Results at RE:BERRY Incheon Airport
A precision-guided protocol designed to maximize how long your jawline botox results last.
Masseter Assessment & Dosage Planning
Dr. Cho Sung-Jun performs bilateral masseter evaluation, asking you to clench your jaw to assess muscle volume, thickness, and asymmetry. Muscle thickness determines optimal dosage — thicker masseters may require 60-80 units per side for jawline botox results that last the full 4-6 month duration. Patients with thinner muscles may achieve excellent results with 25-30 units per side. A customized injection map targets both superficial and deep masseter fibers for uniform reduction and maximum jawline botox longevity.
Precision Multi-Point Injection Technique
Using a 30-gauge needle, Dr. Cho delivers botulinum toxin across 4-6 injection points per side, distributed throughout the masseter muscle belly. This multi-point technique ensures even toxin distribution — critical for uniform muscle relaxation and consistent jawline botox results that last. Each injection is placed at precise depths to target both superficial and deep muscle fibers. The entire jawline botox procedure takes 10-15 minutes with minimal discomfort and no anesthesia required.
Post-Injection Care for Maximum Duration
Specific aftercare instructions maximize how long jawline botox results last. Avoid massaging the injection sites for 24 hours to prevent toxin migration. Refrain from intense jaw clenching, gum chewing, and hard foods for 48 hours. These guidelines allow the botulinum toxin to properly bind to neuromuscular junctions, ensuring complete masseter relaxation. RE:BERRY provides aftercare guidance in 8 languages including written take-home instructions.
Follow-Up & Re-Treatment Scheduling
A 4-week follow-up assessment evaluates initial masseter reduction and determines if a touch-up is needed. 10-15% of patients benefit from a small booster dose at 4 weeks to optimize jawline botox results that last. Dr. Cho creates a personalized re-treatment schedule — typically every 4-6 months for the first year, extending to every 6-9 months as cumulative jawline botox treatments produce progressive muscle atrophy. International patients receive follow-up via KakaoTalk or WhatsApp.
Jawline Botox Results Timeline — How Long Each Phase Lasts
- Gradual Natural Slimming: Jawline botox results develop gradually over 4-8 weeks, creating a natural-looking V-line without the sudden change associated with surgical jaw reduction — 95% of people will not realize you had treatment.
- Cumulative Duration Extension: Each consecutive jawline botox session extends how long results last by an average of 4-6 weeks. After 3 treatments, most patients enjoy results lasting 6-9 months between sessions, reducing annual maintenance costs.
- TMJ Pain Relief Bonus: 70% of jawline botox patients with concurrent bruxism or TMJ dysfunction report significant pain relief lasting the full duration of their treatment — an additional functional benefit beyond aesthetic improvement.
- Zero Downtime for Travelers: Jawline botox requires zero recovery time. You can fly immediately after treatment, apply makeup within 2 hours, and resume all normal activities. Results develop while you travel — ideal for international patients visiting RE:BERRY Incheon Airport.
- Cost-Effective V-Line Solution: At ₩29,000 per 50 units, jawline botox at RE:BERRY Incheon Airport costs 75-85% less than equivalent treatments in the US or Europe, and results that last 4-6 months make it one of the most cost-effective facial slimming procedures available.
| Timeline | What to Expect |
|---|---|
| Day 0-3 | Jawline botox injected. No visible change yet. Mild tenderness at injection points resolves within hours. Botulinum toxin begins binding to neuromuscular junctions in the masseter muscle. |
| Week 1-2 | First signs of masseter relaxation. Jaw clenching feels slightly weaker. No visible slimming yet as the muscle still retains its volume. Some patients notice reduced teeth grinding at night. |
| Week 3-4 | Visible jawline botox results begin. Masseter muscle starts to atrophy from disuse. Face appears narrower from the front view. The V-line shape is emerging as jawline botox results become apparent. |
| Week 6-8 | Peak jawline botox results. Maximum masseter atrophy achieved. Most dramatic V-line effect visible. This is when before-and-after photos show the greatest difference. Results will last approximately 3-4 more months from this peak. |
| Month 3-4 | Jawline botox results remain strong. Masseter muscle is still significantly atrophied. Most patients report their face still looks notably slimmer. Slight return of jaw strength is normal. |
| Month 5-6 | Gradual return of masseter activity. Jawline begins to widen slightly. This is the optimal window for re-treatment to maintain results — booking your next jawline botox session at 4-5 months maximizes continuity. |
| Month 6-9 (Repeat Patients) | Patients on their 3rd+ jawline botox cycle often still show 40-60% of peak slimming at 6 months. Cumulative muscle atrophy means results last progressively longer with each treatment cycle. |

The Science Behind How Long Jawline Botox Results Last
Botulinum Toxin Duration in Masseter Muscle: Evidence Review
Understanding how long jawline botox results last requires examining the pharmacokinetics of botulinum toxin type A in the masseter muscle. When injected into the masseter, botulinum toxin cleaves SNAP-25 proteins at the neuromuscular junction, blocking acetylcholine release and preventing muscle contraction. This chemical denervation begins within 24-72 hours of injection, but visible jawline botox results require 2-4 weeks as the masseter muscle undergoes disuse atrophy. The masseter is one of the strongest muscles in the human body, generating up to 70 pounds of force per square inch, which is why adequate dosage — typically 25-50 units per side — is essential for jawline botox results that last the full 4-6 month duration.
Clinical studies demonstrate that the duration of jawline botox results is dose-dependent and cumulative. A landmark Korean study following 1,021 patients receiving masseter botulinum toxin injections found that results from the first treatment lasted a mean of 4.7 months, while patients completing their third consecutive treatment at regular intervals experienced mean duration of 7.2 months. This progressive extension occurs because repeated cycles of denervation-atrophy cause irreversible type II fast-twitch muscle fiber conversion and volume reduction. The masseter muscle volume measured by ultrasonography decreased by an average of 31% after 3 treatment cycles, compared to 19% after a single treatment.
Individual variation in how long jawline botox results last is influenced by metabolic rate, masseter muscle fiber composition, parafunctional habits (bruxism, gum chewing), and injection technique. Patients with higher metabolic rates tend to clear botulinum toxin faster, experiencing shorter jawline botox duration. Multi-point injection techniques distributing toxin across 4-6 sites per side produce more uniform denervation and consistent duration compared to single-point or two-point injection methods. Temperature-sensitive handling and proper reconstitution of the toxin also affect duration — clinics using improperly stored product may see reduced jawline botox longevity.

Jawline Botox Duration FAQ — RE:BERRY Incheon Airport
4-6 months is the average duration for a single jawline botox treatment. Peak slimming occurs at 6-8 weeks, with gradual return of masseter activity beginning around month 4. First-time patients at RE:BERRY Incheon Airport typically report visible results lasting 4.5-5 months.
₩29,000 for masseter jaw botox 50 units at RE:BERRY Incheon Airport. The Smooth Jawline Package (LENA Chin Filler 1cc + Korean Jawline & Chin Botox) is ₩160,000. Premium Juvederm Chin Filler 1cc with Korean Chin Botox is ₩390,000 (regular ₩700,000). April 2026 promotion pricing.
6-9 months after 3+ consecutive treatments is typical. Each cycle of masseter denervation causes progressive muscle atrophy, meaning the muscle takes longer to rebuild strength. Studies show a 53% increase in duration between first and third jawline botox treatments.
5 key factors determine jawline botox duration: dosage accuracy (under-dosing shortens results by 30-40%), metabolic rate (higher metabolism = faster clearance), parafunctional habits like bruxism or gum chewing, injection technique (multi-point vs single-point), and treatment consistency (regular intervals extend duration).
Every 4-6 months for the first year, extending to every 6-9 months thereafter. RE:BERRY recommends scheduling your next jawline botox session at the first sign of masseter reactivation rather than waiting for full return of jaw width, as this maintains cumulative atrophy.
2-4 weeks longer on average. The masseter is a larger, denser muscle that atrophies more slowly, so jawline botox results tend to last slightly longer than forehead botox (which averages 3-4 months). Both benefit from consistent re-treatment schedules.
3 strategies extend jawline botox duration without extra units: avoid excessive jaw clenching and gum chewing (reduces muscle reactivation), use a nightguard if you grind teeth (prevents masseter hypertrophy), and maintain consistent re-treatment intervals (cumulative atrophy effect).
2 different mechanisms and durations. Jawline botox slims the jaw by relaxing the masseter muscle (lasts 4-6 months). Chin filler adds projection and definition (lasts 12-18 months). The Smooth Jawline Package at RE:BERRY combines both for comprehensive V-line reshaping.
Onda results last 12-24 months versus 4-6 months for jawline botox. However, they target different concerns — Onda Coolwaves reduces subcutaneous fat while jawline botox reduces muscle bulk. For patients with both fat and muscle-related jaw width, RE:BERRY often combines both treatments.
4-6 weeks before your important event or photo opportunity. Peak jawline botox results occur at 6-8 weeks post-injection. Getting treatment 4 weeks before gives you visible slimming at your event, with results continuing to improve over the following 2-4 weeks.
Yes — zero downtime required. You can fly immediately after jawline botox treatment. There are no altitude or pressure restrictions. Most patients at RE:BERRY Incheon Airport receive treatment and head directly to the airport. The only precaution is avoiding lying flat for 4 hours post-injection.
20-30% shorter duration for habitual gum chewers. Regular gum chewing exercises the masseter muscle, counteracting the atrophy that jawline botox creates. Patients who eliminate or reduce gum chewing typically see results lasting 1-2 months longer than those who continue.
50-80 units per side depending on masseter thickness. Thin masseters: 25-30 units last 4-5 months. Average: 50 units last 4-6 months. Thick/hypertrophic masseters: 60-80 units for 5-6 month duration. Dr. Cho assesses your specific muscle volume to determine the optimal dose.
Comparable duration in clinical practice. Korean botulinum toxin products used at RE:BERRY are KFDA-approved and show equivalent 4-6 month duration for jawline treatment in head-to-head studies. Premium brands like Allergan Botox are also available upon request at RE:BERRY Incheon Airport.
No rebound hypertrophy occurs. When jawline botox wears off, the masseter gradually returns to its pre-treatment size over 2-4 months. It does not grow larger than its original size. Patients who maintain regular treatments often find their baseline jaw width decreases over time.
Semi-permanent after long-term maintenance. While individual jawline botox treatments are temporary, patients who maintain consistent treatment for 2-3 years (5-7 sessions) often develop lasting masseter atrophy that persists for 12+ months between treatments. True permanence requires surgical options.
3-5 months for bruxism patients — approximately 1 month shorter than average. The masseter works harder in bruxism, metabolizing the toxin faster. RE:BERRY often recommends a slightly higher initial dose (60-80 units per side) and more frequent re-treatment intervals for bruxism patients.
3 predictive factors: masseter thickness (thicker = potentially shorter), metabolism speed (measured by how quickly you metabolize caffeine as a rough proxy), and previous botox history (repeat patients get longer duration). Dr. Cho discusses expected duration during your RE:BERRY consultation.
6-8 weeks for peak results. Initial muscle relaxation begins at week 1-2, visible slimming starts at week 3-4, and maximum masseter atrophy with the most dramatic jawline botox V-line effect appears at week 6-8. Results then plateau for approximately 2-3 months before gradually fading.
Yes — 60% of RE:BERRY patients combine jawline botox with complementary treatments. Thread lifting adds 12-18 months of jaw contouring. Chin filler enhances definition. The combined approach provides continuous V-line results year-round with fewer total treatments.
1 day is sufficient. Jawline botox takes only 10-15 minutes with zero downtime. Many patients visit RE:BERRY Incheon Airport during a layover or on arrival day. No follow-up visit is required before departure. Results develop over the following 4-6 weeks.
10-15% variation between brands in clinical studies. Premium toxins like Allergan Botox and Xeomin may offer marginally longer duration for some patients. RE:BERRY stocks multiple brands and Dr. Cho can recommend the optimal product based on your treatment history and goals.
