Face Slimming Injection in Gangnam Seoul
Achieve a defined V-line jawline without surgery through precision face slimming injection at RE:BERRY Gangnam. Masseter Botox reduces jawline width by 15-30% over 4-8 weeks, while chin filler creates harmonious proportions. Physician-performed face slimming injection from ₩29,000, two minutes from Gangnam Station Exit 10.
What Is Face Slimming Injection at RE:BERRY Gangnam?
Face slimming injection at RE:BERRY Gangnam uses masseter Botox (50U from ₩29,000) to reduce jaw muscle volume by 15-30%, creating a natural V-line contour within 4-8 weeks without surgery or downtime, combined with optional Juvederm chin filler (₩450,000) for enhanced facial proportions.
At RE:BERRY Gangnam, Medical Director Dr. Yoon-Gon Ryu designs each face slimming injection protocol based on precise analysis of masseter muscle thickness, facial bone structure, and desired contour outcomes. The masseter muscle can become hypertrophied from habitual clenching, bruxism, or genetic predisposition, creating a wide jawline. Botulinum toxin injection causes controlled muscle atrophy over 4-8 weeks, reducing jaw width by 15-30% without affecting chewing function. For comprehensive V-line transformation, Dr. Ryu combines masseter Botox with chin filler to elongate the chin point. Additional options include double chin treatment for submental fat and jawline Botox for platysmal band relaxation. All face slimming injections are performed exclusively by licensed physicians using MFDS-approved products.

How Face Slimming Injection Works at RE:BERRY Gangnam
A precision-guided face slimming injection protocol designed to create natural V-line contours while preserving normal jaw function.
3D Facial Analysis & Muscle Assessment
Dr. Yoon-Gon Ryu conducts a facial structure assessment analyzing masseter muscle thickness, facial bone width, mandibular angle, chin projection, and overall proportions. Your face slimming injection protocol is customized based on masseteric hypertrophy degree and desired slimming percentage. Bruxism patients are identified for appropriate dosing. This consultation takes 15-20 minutes and is included with every treatment at RE:BERRY Gangnam.
Injection Point Mapping & Preparation
The masseter muscle is mapped with 4-6 injection points per side, positioned to maximize slimming while avoiding the parotid gland and facial nerve branches. Ice or topical anesthetic is applied for comfort. For patients combining face slimming injection with chin filler, chin anatomy is assessed for optimal filler placement depth and volume.
Precision Masseter Botox Injection
Botulinum toxin is injected into the masseter at 5-10mm depth using a 30-gauge needle. Standard dosing is 25 units per side (50 units total), with adjustments for thicker muscles (30-40 units per side). The technique targets the lower two-thirds of the masseter to maximize jaw width reduction while preserving chewing efficiency. The entire face slimming injection takes only 10-15 minutes.
Complementary Contouring & Aftercare
For comprehensive V-line results, Dr. Ryu may add chin filler (Juvederm, 1cc from ₩450,000) to elongate the chin point. Optional wrinkle Botox for jaw corners or nefertiti lift technique addresses jowling. Post-procedure instructions: avoid massaging the jaw for 4 hours, refrain from lying flat for 4 hours, and avoid excessive jaw exercise (gum chewing, hard foods) for 2 weeks.
What to Expect from Face Slimming Injection
- Non-Surgical Jaw Width Reduction Face slimming injection reduces masseter muscle volume by 15-30% without surgery, anesthesia, or scarring. The controlled muscle atrophy creates a naturally slimmer jawline that looks like genetic good bone structure rather than an artificial result.
- Zero Downtime Procedure The entire face slimming injection takes 10-15 minutes with no visible marks, bruising (in most cases), or recovery period. Patients return to work, social events, and travel immediately after treatment at RE:BERRY Gangnam.
- Bruxism & TMJ Relief Beyond cosmetic slimming, masseter Botox reduces jaw clenching force by 40-60%, providing significant relief for bruxism (teeth grinding) and temporomandibular joint (TMJ) pain. Many patients report improved sleep quality within 2-3 weeks.
- Natural-Looking V-Line Transformation Gradual muscle reduction over 4-8 weeks ensures no sudden change. Friends and colleagues notice you look slimmer and more refreshed, but the transformation is subtle enough that the face slimming injection remains undetectable.
- Reversible & Adjustable Botulinum toxin effects are temporary (4-6 months). If desired results are not achieved, dosage can be adjusted at the next session. After 3-4 consistent treatments, many patients require reduced dosing as the muscle naturally becomes less hypertrophied.
- Complementary Combination Potential Face slimming injection synergizes with chin filler for V-line enhancement, Revinas or Onda for skin tightening along the jawline, and thread lifting for jowl improvement — allowing comprehensive non-surgical facial reshaping in a single visit.
| Timeline | What to Expect |
|---|---|
| Day 1-3 | No visible change to jaw shape. Possible minor injection-site tenderness that resolves within 24 hours. Normal chewing function preserved. Avoid excessive jaw exercise and massaging the treatment area. |
| Week 1-2 | Botulinum toxin begins binding to neuromuscular junctions. Gradual reduction in masseter contractile force begins. Some patients notice reduced jaw tension and less clenching during sleep. |
| Week 3-4 | Visible narrowing of the jaw angle begins as muscle fibers atrophy. Jaw width reduction of approximately 5-10% at this stage. Face slimming injection results are becoming noticeable, especially from front-facing perspective. |
| Week 6-8 | Peak face slimming effect achieved. Jaw width reduction of 15-30% depending on initial muscle thickness and dosage. V-line contour clearly visible. Bruxism patients report maximum clenching relief. |
| Month 3-4 | Optimal results maintained. Muscle volume at minimum. This is the ideal time to assess whether additional chin filler or jawline contouring would enhance the V-line further. |
| Month 5-6 | Gradual muscle function return begins. Schedule maintenance face slimming injection before full muscle recovery for sustained V-line results. After 3-4 consistent treatments, maintenance intervals may extend to 6-9 months. |

The Science Behind Face Slimming Injection
Peer-reviewed evidence supporting masseter Botox for jawline reduction and facial contouring.
Botulinum Toxin-Induced Masseter Atrophy
Face slimming injection relies on the neuromuscular blocking properties of botulinum toxin type A. When injected into the masseter muscle, the toxin cleaves SNARE proteins at the neuromuscular junction, preventing acetylcholine release and inducing temporary chemical denervation. Without neural stimulation, masseter muscle fibers undergo disuse atrophy — type II fibers reduce in cross-sectional area by 15-30% over 4-8 weeks. Kim et al. (2003) demonstrated via ultrasonography that masseter thickness decreased by 31% at 12 weeks post-injection. The face slimming injection effect is dose-dependent: 25 units per side produces moderate reduction, while 40 units per side achieves more dramatic slimming.
Optimal Dosing and Injection Technique
Park et al. (2017) established that distributing the dose across 4-6 points within the lower two-thirds of the masseter body produces more uniform atrophy than single-point injection, reducing asymmetric results. The injection depth of 5-10mm ensures toxin delivery into the muscle belly while avoiding the parotid gland and facial nerve branches. For bilateral face slimming injection, symmetry outcomes are superior when the same operator performs both sides in a single session using consistent dosing and mirror-image point placement — the standard protocol at RE:BERRY Gangnam.
Long-Term Outcomes and Maintenance
Xie et al. (2014) tracked 112 patients over 5 years and found that after 4+ consecutive face slimming injection treatments, 68% achieved sustained slimming with progressively lower maintenance doses. The masseter undergoes cumulative structural changes — type II to type I fiber transition and reduced fiber count through apoptotic pathways. This explains why maintenance intervals extend from 4-6 months initially to 6-12 months after 3-4 cycles. Normal chewing function is preserved at therapeutic doses.
Combination Approaches for V-Line Enhancement
Wollina et al. (2018) demonstrated that combining masseter Botox with chin-point HA filler produced significantly higher satisfaction scores (8.7/10 versus 6.8/10 for Botox alone) because chin elongation creates optical narrowing that amplifies jaw width reduction. For patients with both muscular and adipose jaw fullness, combining face slimming injection with fat-dissolving injections achieves comprehensive lower-face contouring — the multi-treatment approach practiced at RE:BERRY Gangnam.

“Dr. Ryu combined masseter Botox with chin filler for a complete V-line transformation. The chin filler gave instant definition, and the Botox gradually slimmed my jaw over following weeks. Friends in Tokyo could not figure out what changed — exactly the natural result I wanted.”
“As a bruxism sufferer, I originally came for the TMJ pain relief. The face slimming effect was a wonderful bonus. After 3 treatments over 12 months, I no longer need a night guard, and my jaw is visibly narrower. The whole team at RE:BERRY Gangnam spoke excellent English and the process was very comfortable.”
