Face Slimming Injection in Myeongdong Seoul — Masseter Botox V-Line Contouring
RE:BERRY Myeongdong delivers precise face slimming injection using masseter Botox to reduce jaw width by 15-30% without surgery. Our licensed Aesthetic Medicine Specialists target the masseter muscle with calibrated units of botulinum toxin, creating a naturally tapered V-line silhouette within 4-6 weeks. Located 2 minutes from Myeongdong Station, open 365 days with 8-language support for international visitors seeking non-surgical facial contouring in Seoul.
What Is Face Slimming Injection at RE:BERRY Myeongdong?
Face slimming injection at RE:BERRY Myeongdong uses masseter Botox (50 units) to reduce jawline width by 15-30% over 4-6 weeks, creating a natural V-line without surgery, starting from ₩29,000 per area at RE:BERRY Myeongdong Seoul, with results lasting 4-6 months.
Face slimming injection works by relaxing the masseter (jaw-clenching) muscles through precise botulinum toxin administration. Unlike surgical jaw reduction, this non-invasive approach requires zero downtime and produces gradual, natural-looking results that colleagues and friends perceive as weight loss rather than a cosmetic procedure. At RE:BERRY Myeongdong, Dr. Seung-Jae Baek evaluates each patient’s masseter thickness using visual assessment and palpation to determine the optimal injection points and dosage. For patients seeking additional facial contouring, face slimming injection pairs exceptionally well with chin filler augmentation to enhance the V-line effect from both angles — a slimmer jaw above and a more projected chin below. Patients who also want to address submental fullness can combine this treatment with our double chin treatment for comprehensive lower face contouring.

How Face Slimming Injection Works at RE:BERRY Myeongdong
Our four-step face slimming injection protocol delivers precise masseter reduction for natural V-line contouring.
Facial Assessment & Jaw Muscle Evaluation
Dr. Seung-Jae Baek examines your masseter muscle size, facial bone structure, and bite pattern. You clench your jaw so the doctor can palpate masseter thickness — patients with hypertrophic masseters (thicker than 13mm) typically see the most dramatic face slimming injection results. Dr. Baek also checks for temporomandibular joint (TMJ) issues and bruxism, which masseter Botox simultaneously treats as a secondary benefit. The consultation takes 10-15 minutes and includes a treatment plan with expected millimeter reduction.
Injection Point Mapping for Face Slimming
Using anatomical landmarks, the doctor marks 3-5 precise injection points on each masseter muscle. The injection sites are positioned in the lower two-thirds of the masseter belly, avoiding the superficial portion near the parotid gland and the zygomatic arch insertion. This strategic placement ensures maximum muscle volume reduction in the jawline area while preserving normal chewing function. RE:BERRY Myeongdong uses ultra-fine 30G needles that most patients compare to a brief mosquito bite sensation.
Precise Botulinum Toxin Administration
50 units of botulinum toxin are distributed across the mapped points on each side (25 units per masseter). The entire face slimming injection procedure takes only 10-15 minutes. Dr. Baek uses a precise aspiration technique before each injection to confirm the needle is within the muscle belly and not in a vascular structure. For patients with particularly thick masseters or a history of teeth grinding, dosage may be adjusted to 60-80 units total for optimal face slimming results.
Aftercare & Follow-Up Plan
Immediately after your face slimming injection, you receive specific aftercare guidelines: avoid lying flat for 4 hours, no massage or heat on the jaw area for 24 hours, and skip intense exercise the same day. These instructions prevent Botox migration beyond the target muscle. RE:BERRY Myeongdong schedules a complimentary follow-up check at 2 weeks to assess muscle response and symmetry. Full face slimming results develop gradually over 4-6 weeks as the masseter muscle atrophies from reduced nerve signaling.
What to Expect from Face Slimming Injection at RE:BERRY Myeongdong
- Non-Surgical V-Line: Achieve 15-30% jaw width reduction without bone contouring surgery, general anesthesia, or extended recovery. Face slimming injection is the safest route to a V-line silhouette.
- Zero Downtime: Return to shopping in Myeongdong immediately after treatment. Tiny needle marks fade within hours, and there is no bruising in most patients.
- Natural-Looking Results: Gradual 4-6 week onset means changes look natural — colleagues notice you look slimmer, not that you had a procedure.
- TMJ & Bruxism Relief: Face slimming injection simultaneously reduces jaw clenching, teeth grinding, and TMJ-related headaches — a medical benefit beyond aesthetics.
- Reversible & Adjustable: Unlike surgery, face slimming injection results gradually reverse over 4-6 months if you choose not to maintain. Dosage is adjustable each session for your ideal jaw width.

The Science Behind Face Slimming Injection
Peer-reviewed research supporting botulinum toxin masseter reduction for facial contouring at RE:BERRY Myeongdong.
Mechanism of Botulinum Toxin in Masseter Reduction
Botulinum toxin type A inhibits acetylcholine release at the neuromuscular junction by cleaving SNAP-25 proteins in the presynaptic nerve terminal. When injected into the masseter muscle, this blocks the neural signals that cause involuntary clenching and hypertrophy. Over 4-6 weeks, the denervated masseter muscle fibers undergo disuse atrophy — the same physiological process that occurs when any skeletal muscle is immobilized. The reduction in muscle volume directly translates to visible jaw width narrowing. Unlike surgical mandibular angle reduction, face slimming injection preserves the bone structure entirely and allows for reversibility. The treatment is particularly effective in Asian populations where masseter hypertrophy is a primary contributor to a wide lower face, as opposed to bony prominence which requires surgical intervention.
Clinical Evidence for Masseter Botulinum Toxin
A landmark study by To et al. (2001) first established the efficacy of botulinum toxin for masseter reduction, demonstrating measurable jaw width decrease in patients with masseter hypertrophy. Subsequent research has refined dosing protocols and confirmed the safety profile. Kim et al. (2003) evaluated face slimming injection outcomes in 1,021 Korean patients receiving 25 units per side, finding that 93.1% achieved satisfactory facial contour change with an average masseter thickness reduction of 31% measured by ultrasonography at 12 weeks post-injection. The study confirmed that the procedure had no significant impact on normal mastication function despite the dramatic volumetric reduction. More recent research using 3D facial imaging by Xie et al. (2014) demonstrated that the maximum volume reduction occurs between weeks 8-12 post-injection, with the lower posterior portion of the masseter showing the greatest degree of atrophy.
Optimal Dosing and Injection Technique
Research by Lee et al. (2019) comparing different dosing regimens for face slimming injection found that 25 units per masseter (50 units total) provided optimal balance between efficacy and safety for most patients, while severe hypertrophy cases benefited from 30-40 units per side. The study used ultrasonographic measurement to confirm that multi-point injection across 3-5 sites in the lower masseter belly produced more uniform atrophy than single-point injection techniques. Importantly, injections confined to the lower two-thirds of the masseter muscle preserved the zygomatic portion, maintaining natural facial expression and smile width — a critical aesthetic consideration that distinguishes expert technique from novice approaches.

What Our Patients Say About Face Slimming Injection at RE:BERRY Myeongdong
“I came from Bangkok specifically for face slimming injection at RE:BERRY Myeongdong. Dr. Baek explained everything clearly, and the injection took only 10 minutes. Six weeks later, my friends keep asking if I lost weight. The V-line difference is incredible — and at 29,000 won, it was the best beauty investment of my trip.”
“I have been getting masseter Botox in Tokyo for years but the price was 5 times higher. My friend recommended RE:BERRY Myeongdong, so I tried it during my Seoul shopping trip. Same result, fraction of the price. Dr. Son was very precise with the injection points. I will come back every 5 months.”
“As someone who grinds teeth at night, I was skeptical that face slimming injection would also help my jaw pain. But Dr. Baek was right — the TMJ headaches stopped within 2 weeks, and my face visibly narrowed by week 5. Two benefits in one treatment. The whole experience at RE:BERRY Myeongdong was professional and comfortable.”

Face slimming injection uses botulinum toxin to shrink the masseter muscle (soft tissue), reducing jaw width by 15-30% over 4-6 weeks with zero downtime.
