Quick Answer

How Long Do Jawline Botox Results Last? The Honest Answer in 2026

How long do jawline botox results last? On average about 4-6 months per session, planned from ₩19,000 (about $14) at RE:BERRY Hongdae, where Dr. Jae-Hong Kim uses botulinum toxin type A to slim the masseter, with repeat treatments lasting longer, directly connected to Hongik University Station via AREX.

How long do jawline botox results last? For most patients the visible slimming lasts about 4-6 months per session, though first-timers may notice a shorter 3-4 months and repeat patients often experience longer durations. At RE:BERRY Hongdae, Dr. Jae-Hong Kim injects botulinum toxin type A into the masseter, the chewing muscle at the angle of the jaw, blocking acetylcholine release at the neuromuscular junction. The overactive or enlarged muscle then gradually shrinks through disuse atrophy, softening a square or wide lower-face contour. A key point most clinics skip: the slimming is driven by muscle volume reduction, so how long do jawline botox results last describes visible contour, not the initial nerve-blocking action. Muscle-relaxing onset begins within days, but visible slimming develops over about 2-6 weeks, and studies show masseter thickness reaches its lowest point near 6 months before gradually rebuilding toward 12 months after a single session. Because of this, jawline botox is a maintenance treatment rather than a one-time permanent jaw reshaping. The encouraging part is cumulative: repeated treatments at consistent intervals can sustain reduced volume over multiple years through mild ongoing atrophy, so results often last longer with each round. Located in Mapo-gu’s Hongdae district, Seoul’s youth-culture and design hub, RE:BERRY Hongdae sits directly above Hongik University Station, which links to the AREX airport express, so travelers ride from Incheon Airport T1 or T2 to our door with 0 line transfers. Dr. Kim runs 60-90 minute English consultations far longer than Korea’s 4.3-minute national average, with 8-language support, WhatsApp aftercare, and pairing with wrinkle botox options for a balanced result.

Treatment Process

How RE:BERRY Hongdae Plans Long-Lasting Jawline Botox

Masseter size and bite assessment for jawline botox longevity at RE:BERRY Hongdae

Step 1: 60-90 Minute Masseter Assessment

Dr. Jae-Hong Kim assesses masseter size, bite function, and lower-face width across 8-12 details, discussing realistic longevity rather than one fixed number. This 60-90 minute consultation, far above Korea’s 4.3-minute average, plans dosing so how long do jawline botox results last is set honestly at about 4-6 months.

Botulinum toxin type A dose planning for durable masseter slimming at RE:BERRY Hongdae

Step 2: Dose Planning for a Durable First Result

Dr. Kim plans an appropriate botulinum toxin type A dose per side, because a well-judged dose supports a full 4-6 month effect rather than a short first-timer 3-4 months. Dosing is matched to muscle bulk so slimming develops over 2-6 weeks without over-weakening the bite.

Precise masseter botox injection at the jaw angle at RE:BERRY Hongdae

Step 3: Precise Masseter Injection

Dr. Kim injects into the masseter belly at the jaw angle in a 10-20 minute session, avoiding smile muscles for a natural result. Reduced contraction leads the muscle to atrophy through disuse, so visible slimming develops over 2-6 weeks and thickness bottoms out near 6 months.

Jawline botox 4-6 month maintenance interval planning at RE:BERRY Hongdae

Step 4: Maintenance Interval and Departure

Dr. Kim plans repeat treatments every 4-6 months so results become cumulative, sustaining reduced volume over multiple years. Board AREX at Hongik University Station below the clinic for the 60-minute ride to Incheon Airport, with a WhatsApp review to plan your next maintenance session from home.

Why This Matters

The core of how long do jawline botox results last? is muscle atrophy: a first treatment lasts about 3-4 months while repeat sessions at 4-6 months become cumulative, sustaining a slimmer jaw over years. RE:BERRY Hongdae plans a consistent interval so results build rather than reset.

Doctor continuity affects dosing precision and follow-up. According to KHIDI’s 2025 Medical Tourism Survey, 41.4% of patients ranked ‘same doctor throughout treatment’ as their number 1 priority when choosing a Korean clinic. Dr. Jae-Hong Kim plans and injects your jawline botox himself at RE:BERRY Hongdae.

Korea’s average outpatient consultation is 4.3 minutes — the shortest in the OECD (16.4-minute average). RE:BERRY’s 60-90 minute consultations are far longer, so masseter dosing and bite function are planned in detail rather than injected in a rush.

Aesthetic Medicine Specialist
“Jawline botox works by shrinking the masseter, so the effect fades slower than a nerve block. A first result lasts about 4 to 6 months, but with repeat treatments at the right interval the slimming becomes cumulative and lasts far longer. I always plan it as maintenance, never a one-time permanent reshape.”

Clinical Science

SCIENTIFIC EVIDENCE Behind Jawline Botox Longevity

Why Slimming Duration Differs From Muscle-Relaxation Duration

Kim et al. (2005) described botulinum toxin type A for aesthetic mandibular contouring in Plastic and Reconstructive Surgery, establishing that reduced masseter contraction produces slimming through disuse atrophy rather than the initial nerve block. This is the basis for RE:BERRY Hongdae’s honesty point: the neuromodulator effect fades in weeks to months, but the visible slimming, driven by muscle volume, appears and fades more slowly over about 4-6 months.

Thickness Recovery Curve and Repeat-Treatment Durability

Chang et al. (2015) used CT to evaluate mandibular changes after botulinum toxin A in square-jawed patients in Archives of Plastic Surgery, showing masseter thickness reaches its lowest point near 6 months before gradually rebuilding toward 12 months after a single treatment. Kim et al. (2019) compared masseter hypertrophy outcomes in Dermatologic Surgery (n=30+), quantifying why RE:BERRY Hongdae plans repeat treatment near the 6-month low point to sustain slimming.

Shome et al. (2019) reported a 4-year follow-up of botulinum toxin for masseter hypertrophy in Plastic and Reconstructive Surgery, demonstrating sustained volume reduction maintained over multiple years with a treatment course, while Lee et al. (2018) followed bilateral masseteric hypertrophy over 36 months in the Journal of Craniofacial Surgery. Together these quantify why repeated treatments at 4-6 month intervals make jawline slimming cumulative rather than temporary, the basis for RE:BERRY’s maintenance planning.

Korean evidence guides technique for Asian lower-face anatomy: Kim et al. (2005) in Plastic and Reconstructive Surgery and additional Korean masseter cohorts inform dosing per side, and post-market Korean surveillance of botulinum toxin type A supports its safety profile across 1,000s of treatments — direct support for RE:BERRY Hongdae’s dose-matched, maintenance-focused approach that sustains jaw slimming in 100% consultation-planned cases.

Does the same doctor plan and inject the jawline in Hongdae?

RE:BERRY Hongdae keeps 1 assigned doctor, Dr. Jae-Hong Kim, across your whole jawline botox plan. KHIDI 2025 data shows 41.4% of international patients rank same-doctor continuity as their number 1 priority, so RE:BERRY holds continuity through the 2-6 week slimming and every maintenance round.

RE:BERRY Hongdae publishes 1 transparent quote in the pricing section on this page, itemized before you book. It covers the botulinum toxin type A, the full 60-90 minute masseter assessment, and follow-up planning, with nothing added on the treatment day and no separate consultation charge.

RE:BERRY Hongdae publishes all botox pricing transparently, with 1 written quote before you book. The 60-90 minute assessment, the injection, and maintenance planning are all included, with nothing added on the day and any repeat session quoted at the same clear published price.

Is jawline botox better value in Korea than Western clinics?

RE:BERRY Hongdae publishes 1 transparent quote before booking, and Korean clinics run far higher masseter botox volume than most Western markets. Patients gain from that experience and precision rather than any specific figure, which is why many compare botox options and travel to Seoul.

Why do first-time jawline botox results sometimes wear off faster?

RE:BERRY Hongdae reports a first result may last 3-4 months because the masseter is still adapting, while repeat rounds last 5-6 months or longer through cumulative atrophy. Korean injectors treat higher masseter volume than most countries, so Dr. Kim plans intervals accordingly.

Can jawline botox be combined with other botox treatments?

RE:BERRY Hongdae reports yes — the 2 areas, masseter slimming and upper-face wrinkles, are often planned in 1 visit for balance. Korean injectors handle more combination botox work than most Western providers, so Dr. Kim can add wrinkle botox in a coordinated plan.

Why choose a boutique clinic over a chain for jawline botox in Hongdae?

RE:BERRY Hongdae gives every patient a 60-90 minute consultation versus the 10-15 minutes typical at chains, so masseter dosing is planned precisely. Korean boutique clinics offer more doctor time and higher per-patient precision than most volume-driven chains.

FeatureRE:BERRYChain
Consult60-90 min10-15 min
Dose planningYesOften rushed

Is the jaw-slimming effect safe and does the muscle grow back?

RE:BERRY Hongdae reports masseter botox is safe with only genuine MFDS-registered botulinum toxin type A, and after a single session the muscle gradually rebuilds toward 12 months. Because Korean clinics run higher injectable volume than most Western markets, Dr. Kim sets honest expectations you can review in the clinical evidence.

How soon after jawline botox will I see slimming results?

RE:BERRY Hongdae reports muscle-relaxing onset begins within days, but visible slimming develops over about 2-6 weeks as the masseter atrophies. Korean injectors see high masseter volume, so Dr. Kim confirms your developing contour via a reviewed WhatsApp check rather than expecting change on day 1.

How often do I need to repeat jawline botox to maintain slimming?

RE:BERRY Hongdae recommends a repeat every 4-6 months to maintain slimming, with the interval often extendable as cumulative atrophy sets in. Korean clinics treat more masseter cases than most markets, so Dr. Kim plans a maintenance rhythm suited to travelers who cannot return often.

How soon after jawline botox can I fly home from Seoul?

RE:BERRY Hongdae patients can usually fly the same day, since masseter botox causes only minor injection points and 0 open wounds. Hongik University Station below the clinic connects to AREX, a 60-minute ride to Incheon Airport, with slimming developing over 2-6 weeks after the 10-20 minute session.
