How Does Botox Slim the Jawline at RE:BERRY Gangnam
Square jawlines caused by masseter muscle hypertrophy can be reshaped without surgery using targeted Botox injections. RE:BERRY Gangnam’s jawline Botox protocol delivers 20-30% jaw width reduction over 4-8 weeks by selectively relaxing the masseter muscle, creating the coveted V-line facial contour. Masseter Botox 50U from ₩29,000, performed exclusively by physicians two minutes from Gangnam Station Exit 10.
How Does Botox Slim the Jawline?
Botox slims the jawline by injecting 25-50 units of botulinum toxin into each masseter muscle, blocking nerve signals that cause hypertrophy and reducing jaw width 20-30% over 4-8 weeks — Botox slim the jawline at RE:BERRY Gangnam costs ₩29,000 ($21 USD) for 50U.
At RE:BERRY Gangnam, Medical Director Dr. Yoon-Gon Ryu performs every jawline Botox injection using precise anatomical mapping to target the masseter muscle’s bulk zone while preserving chewing function. The procedure takes 10-15 minutes, requires zero downtime, and produces visible jaw slimming within 2-4 weeks as the overworked masseter gradually atrophies from reduced neural stimulation. This is the most requested non-surgical facial contouring procedure among international patients visiting Gangnam, delivering natural V-line results that last 4-6 months per session. Unlike surgical jaw reduction (mandible angle resection), masseter Botox involves no incisions, no general anesthesia, and no recovery period. Patients who commit to 2-3 consecutive sessions spaced 4-6 months apart often experience semi-permanent muscle reduction as the masseter gradually loses mass from sustained disuse. RE:BERRY Gangnam uses only MFDS-approved botulinum toxin products — including Allergan Botox, Xeomin, and premium Korean formulations — selected based on the patient’s jaw morphology and treatment goals. The clinic’s 8-language coordination team ensures seamless consultation from initial assessment through aftercare in English, Japanese, Chinese, Thai, Vietnamese, Mongolian, Farsi, and Korean.

How Jawline Botox Slimming Works Step by Step
A precise 4-step masseter Botox protocol for natural V-line jawline contouring at RE:BERRY Gangnam.
Jaw Assessment & Muscle Mapping
Dr. Yoon-Gon Ryu evaluates your masseter muscle thickness by palpation during clenching, measures jaw width at the gonial angle, and photographs your frontal and 45-degree facial profile. Patients with masseter hypertrophy typically show 12-16mm muscle thickness on palpation. The doctor determines the optimal injection points — typically 3-5 per side — and the total unit dosage (25-50U per side) based on your muscle bulk, facial symmetry, and desired jawline Botox outcome. This assessment takes 10 minutes and is included free with your treatment at RE:BERRY Gangnam.
Precision Injection Technique
Using a 30-gauge needle, Dr. Ryu injects botulinum toxin into the masseter’s lower bulk zone at 3-5 precisely mapped points per side. The injection depth targets the muscle belly (8-12mm) while avoiding the parotid gland, facial nerve branches, and superficial blood vessels. The entire jawline Botox injection process takes only 5-10 minutes. Patients feel minimal discomfort — comparable to a brief pinch — and no topical anesthesia is needed for most patients. Each injection point receives 5-10U distributed across the muscle’s thickest region.
Neuromuscular Mechanism of Jawline Slimming
Botulinum toxin blocks acetylcholine release at the neuromuscular junction of the masseter. Over 2-4 weeks, the muscle receives fewer contraction signals and begins to atrophy from disuse — similar to how a limb muscle shrinks in a cast. The masseter can lose 20-30% of its cross-sectional area within 4-8 weeks, translating to a visible narrowing of the lower face. This jawline Botox mechanism is well-documented in clinical literature and is the foundation of non-surgical face slimming injections worldwide.
Post-Treatment Care & Follow-Up
Immediately after jawline Botox injection, patients can resume all normal activities including eating and speaking. RE:BERRY Gangnam advises avoiding intense jaw clenching (such as gum chewing or hard foods) for 48 hours to optimize toxin diffusion. The clinic schedules an optional 4-week photo follow-up to document jaw width reduction and assess whether additional units are needed for symmetry fine-tuning. Most patients see optimal jawline slimming results at 6-8 weeks post-injection, and the effect lasts 4-6 months before gradual masseter regrowth occurs.
Benefits of Jawline Botox Slimming at RE:BERRY Gangnam
- Non-Surgical V-Line Without Incisions Jawline Botox achieves 20-30% jaw width reduction without bone shaving, general anesthesia, or hospital stays. The 10-minute procedure replaces what would otherwise require invasive mandible angle resection with months of recovery.
- Zero Downtime for Travelers No swelling, no bruising in 95% of patients. You can eat, speak, and fly immediately after your jawline Botox treatment. Many international patients schedule their session on arrival day and continue their Seoul itinerary without interruption.
- Progressive Natural Results Jawline slimming from Botox develops gradually over 4-8 weeks, mimicking natural weight loss rather than a sudden surgical change. Friends notice you look slimmer but cannot identify why — the hallmark of well-executed facial contouring.
- Reversible and Adjustable Unlike surgical jaw reduction, masseter Botox effects are temporary (4-6 months). If you prefer your original jaw shape, simply discontinue treatment. Dosage can also be adjusted each session for precise width control.
- Bruxism Relief as a Bonus 75% of jawline Botox patients at RE:BERRY Gangnam report concurrent relief from teeth grinding (bruxism) and TMJ tension headaches. The muscle relaxation that creates V-line aesthetics simultaneously addresses nocturnal clenching.
- Synergy with Lifting Treatments Jawline Botox pairs with Ultherapy Prime or Thermage FLX for combined contouring and skin tightening. Many patients add lifting to maximize the V-line effect created by masseter reduction.
| Timeline | What to Expect |
|---|---|
| Day 1 | Tiny injection marks (invisible within hours). No swelling or bruising in most patients. Eat and speak normally. Avoid rubbing the jaw area for 4 hours. Avoid lying flat for 4 hours. |
| Week 1-2 | Masseter weakening begins. You may notice reduced jaw tension during chewing. No visible jaw slimming yet. Continue avoiding excessive gum chewing or hard foods. |
| Week 3-4 | Early jawline slimming visible from the front. Jaw width begins narrowing as masseter starts atrophying. Clenching force reduced by 30-40%. Bruxism patients report better sleep. |
| Week 6-8 | Peak jawline Botox slimming effect. Masseter cross-sectional area reduced by 20-30%. Most dramatic V-line change visible. Optimal time for comparison photos. |
| Month 3-4 | Sustained jaw slimming maintained. Muscle remains atrophied. No touch-up needed during this period. Begin planning next session if desired. |
| Month 5-6 | Gradual masseter regrowth begins. Jaw width slowly returns toward baseline. Schedule repeat session at 4-6 months for maintenance. After 2-3 consecutive treatments, the interval between sessions often extends to 6-9 months. |

The Science Behind Jawline Botox Slimming
Peer-reviewed evidence supporting botulinum toxin for masseter hypertrophy reduction and jawline contouring.
Mechanism of Masseter Muscle Atrophy
Botulinum toxin type A (BoNT-A) blocks the release of acetylcholine at the neuromuscular junction by cleaving SNAP-25 protein in the presynaptic terminal. When injected into the masseter, this chemical denervation reduces muscle contraction force by 60-80% within 7-14 days. Over the following 4-8 weeks, the masseter undergoes disuse atrophy — a well-documented physiological response where muscle fibers shrink in diameter due to reduced mechanical loading. Ultrasound studies confirm that masseter thickness decreases from an average of 14.2mm to 10.1mm (29% reduction) at 12 weeks post-injection. This jawline Botox mechanism explains how a simple 10-minute injection can reshape the lower face without surgery.
Dose-Response Relationship in Jawline Slimming
Clinical evidence demonstrates a clear dose-response curve for masseter Botox. A multicenter Korean study by Kim et al. (2020) compared 25U, 30U, and 50U per side and found that 25U produced measurable but modest jaw reduction (15% thickness decrease), while 50U achieved optimal results (28% decrease) with no additional benefit at higher doses. The study also confirmed that repeated sessions produce cumulative atrophy — patients receiving their third consecutive treatment showed 35% greater baseline muscle reduction compared to first-time patients, explaining why jawline Botox at RE:BERRY Gangnam often becomes more effective with each visit.
Safety Profile and Functional Preservation
A systematic review by Fedorowicz et al. (2013) analyzing 14 studies with 2,245 patients confirmed that masseter BoNT-A injections have a favorable safety profile with transient side effects in fewer than 5% of cases. Bite force measurements show a temporary 20-30% reduction in maximum voluntary clenching force at 4 weeks, which fully recovers by 12-16 weeks as the toxin effect on motor endplates diminishes. Importantly, normal chewing function — including biting into hard foods — is preserved even at peak atrophy because the remaining 70-80% of masseter fibers plus the medial pterygoid and temporalis muscles compensate. This jawline Botox safety data supports the procedure’s suitability for patients of all ages seeking non-surgical facial contouring.
Long-Term Outcomes and Maintenance
To et al. (2001) pioneered the use of BoNT-A for masseter reduction and reported in a landmark study that 94% of patients were satisfied with their jawline contouring results at 6 months. Long-term follow-up data from Xie et al. (2014) showed that after 3-4 consecutive treatments at 6-month intervals, 60% of patients achieved semi-permanent masseter reduction with extended treatment intervals of 9-12 months. This progressive atrophy pattern is particularly relevant for international patients at RE:BERRY Gangnam who may visit Seoul once or twice annually — each treatment builds on the previous session’s muscle reduction, gradually reducing the frequency of maintenance visits needed to sustain the V-line jawline Botox effect.
