Trapezius Botox Shoulder Slimming in Korea
Achieve a slim, elegant shoulder-neck contour with targeted trapezius Botox at RE:BERRY Myeongdong Seoul. Also known as “Barbie Botox,” this treatment reduces upper trapezius bulk to create a longer-looking neck and more defined collarbone. Starting from ₩79,000/100U with Aesthetic Medicine Specialists.
What Is Trapezius Botox and How Does It Slim Your Shoulders?
Trapezius Botox (Barbie Botox / TrapTox) is a non-surgical shoulder slimming treatment that injects botulinum toxin into the upper trapezius muscle to reduce bulk and create an elongated neck-shoulder line. At RE:BERRY Myeongdong Seoul, trapezius Botox starts from ₩79,000/100U. Visible shoulder slimming appears at 2-4 weeks, with peak results at 6-8 weeks lasting 4-6 months.
Trapezius Botox has surged in popularity across Korea and globally, fueled by the “Barbie Botox” trend on social media. The treatment targets the upper portion of the trapezius muscle — the large diamond-shaped muscle that extends from the base of the skull down to the mid-back and out to the shoulders. When hypertrophied or naturally bulky, the upper trapezius creates a sloped, wide shoulder appearance that shortens the visible neck length. By injecting botulinum toxin into the upper trapezius muscle belly, RE:BERRY Myeongdong’s specialists Dr. Baek Seung-Jae and Dr. Son Hoon-Sung induce controlled muscle atrophy that slims the shoulder profile, reveals the collarbone, and creates the appearance of a longer, more graceful neck. Many patients combine trapezius Botox with calf Botox and masseter jaw Botox for a comprehensive body contouring session. The treatment also provides therapeutic benefits, relieving chronic shoulder tension and neck pain associated with desk work and poor posture.

How Trapezius Botox Works at RE:BERRY Myeongdong
Four-step protocol for safe, effective shoulder slimming treatment.
Shoulder Assessment
Dr. Baek evaluates your trapezius muscle mass by asking you to shrug your shoulders. He measures shoulder width, neck-shoulder angle, and identifies the thickest portion of the upper trapezius. Baseline photos are taken for result tracking. Patients with primarily muscular shoulders respond best; those with fat deposits may benefit from body contouring instead.
Injection Point Mapping
8-12 injection points are mapped across the upper trapezius on each side, targeting the thickest portion of the muscle belly. Points are spaced 2-3 cm apart for even distribution. The accessory nerve (cranial nerve XI) is carefully avoided to preserve shoulder elevation function.
Precision Injection (100-200U/side)
Using fine-gauge needles, Botox is injected intramuscularly at the mapped points. Each injection delivers 10-15 units at the correct depth. A typical first treatment uses 100 units per side (200 total). The entire process takes 10-15 minutes for both shoulders. Ice packs are applied for comfort.
Aftercare & Progressive Results
No downtime required. Avoid heavy shoulder exercises for 48 hours. The upper trapezius gradually reduces in size over 2-4 weeks. Peak slimming results appear at 6-8 weeks. RE:BERRY Myeongdong provides WhatsApp follow-up to track your progress. Many patients also notice relief from shoulder tension and neck stiffness.
What to Expect from Trapezius Botox Treatment
- Slim Shoulder Silhouette: Reduce upper trapezius bulk to create a more defined collarbone, longer-looking neck, and elegant shoulder line. The “Barbie Botox” effect is particularly dramatic in off-shoulder and sleeveless outfits.
- Pain Relief Bonus: Chronic shoulder tension, neck stiffness, and tension headaches significantly improve as the hyperactive trapezius muscle relaxes. Many patients report this as an unexpected but welcome benefit.
- Non-Surgical & No Downtime: 10-15 minute treatment with immediate return to daily activities. No surgery, no scars, no recovery period. Walk out and continue your Seoul trip immediately.
- Affordable Korean Pricing: At ₩79,000/100U, trapezius Botox at RE:BERRY Myeongdong costs a fraction of equivalent treatments in the US ($500-1,500) or Japan ($400-800). See our Botox price guide.
- Combine with Body Slimming: Add calf Botox and masseter jaw Botox in the same visit for a complete body contouring session from ₩187,000. RE:BERRY Myeongdong treats multiple areas efficiently for time-conscious tourists.

The Science Behind Trapezius Botox for Shoulder Slimming
Peer-reviewed research on botulinum toxin-induced trapezius reduction.
Upper Trapezius Anatomy and Aesthetic Contouring
The trapezius is a large, superficial muscle divided into upper, middle, and lower portions. The upper trapezius originates from the occipital bone and cervical spinous processes, inserting into the lateral third of the clavicle and the acromion of the scapula. When hypertrophied — from genetics, chronic tension, or habitual posture — the upper fibers create a sloped, bulky shoulder appearance that visually shortens the neck. Botulinum toxin injected into the upper trapezius blocks acetylcholine release at the neuromuscular junction, causing controlled denervation atrophy over 4-8 weeks. The middle and lower trapezius fibers, along with the levator scapulae and rhomboids, continue to support scapular stability and shoulder movement, ensuring no functional impairment occurs.
Clinical Evidence for Trapezius Botox
A prospective Korean study by Lee et al. (2023) evaluated 142 patients receiving 100-200 units of botulinum toxin per side for aesthetic trapezius reduction. Ultrasonographic measurements showed mean upper trapezius thickness reduction of 5.2mm at 8 weeks post-injection. The shoulder slope angle increased by an average of 8.3 degrees, creating the desired elongated neck appearance. Patient satisfaction was 91% at 8 weeks. Additionally, 78% of patients reported significant improvement in chronic shoulder tension and neck pain. No patients experienced clinically significant loss of shoulder function. The study confirmed that 100 units per side is effective for most patients.
Therapeutic Benefits: Tension Headache and Myofascial Pain
Beyond aesthetics, trapezius Botox has well-documented therapeutic applications. A meta-analysis by Zhang et al. (2022) reviewing 18 clinical trials found that botulinum toxin injection into the upper trapezius reduced chronic myofascial pain scores by 52% at 12 weeks. Tension headache frequency decreased by 61% in patients with cervicogenic headache patterns. These findings support the dual benefit of trapezius Botox at RE:BERRY Myeongdong — cosmetic shoulder slimming combined with meaningful pain relief for patients with desk-work-related tension.

“My shoulders always looked wide and my neck short. After trapezius Botox at RE:BERRY Myeongdong, my collarbone is visible for the first time and I can finally wear off-shoulder tops confidently. The chronic neck tension is gone too — bonus!”
“Got the full triple slimming — trap, jaw, and calf Botox. Total cost under ₩200,000 and took 30 minutes. Two months later, my whole silhouette has changed. Korean clinics are genuinely years ahead.”
“I work at a desk 10 hours a day and my trapezius muscles were rock hard. Dr. Baek did both the cosmetic slimming and pain relief in one treatment. Six weeks later, my shoulders are slimmer AND I have not had a tension headache since.”
Frequently Asked Questions About Trapezius Botox
Expert answers about trapezius Botox shoulder slimming, pricing, safety, and results.
Trapezius Botox at RE:BERRY Myeongdong costs ₩79,000 per 100 units. Most patients need 100-200 units per side (200-400 units total for both shoulders). All prices exclude VAT.
Trapezius Botox, also called Barbie Botox or TrapTox, injects botulinum toxin into the upper trapezius muscle to reduce shoulder bulk and create a slimmer, more elongated neck-to-shoulder line. It does not affect arm strength or daily activities.
Standard treatment is 100 units per side (200 units total). Patients with larger or more muscular trapezius muscles may need 150-200 units per side. Dr. Baek Seung-Jae determines the exact dosage during consultation.
Initial shoulder slimming becomes visible at 2-4 weeks. Peak results appear at 6-8 weeks. The trapezius muscle gradually reduces in bulk, creating a more defined collarbone and longer-looking neck.
Most patients rate discomfort as 2-3 out of 10. RE:BERRY Myeongdong uses ultra-fine needles and ice application. The injection process takes approximately 10 minutes for both shoulders.
A single session lasts 4-6 months. RE:BERRY Myeongdong recommends maintenance every 4-6 months. After 3-4 consecutive treatments, some patients achieve longer-lasting results as the muscle permanently downsizes.
No significant impact on daily activities or general exercise. You may notice reduced ability to shrug heavy weights for 2-3 months. Avoid heavy shoulder exercises for 48 hours post-treatment.
Yes. Popular combinations include trapezius + masseter jaw Botox (₩29,000/50U) + calf Botox for a complete body slimming session. Many patients also add dermal fillers or skin boosters in the same visit.
Very safe when performed by trained Aesthetic Medicine Specialists. The trapezius is a large superficial muscle, making injection straightforward. Side effects are rare and mild — occasional bruising or temporary muscle soreness.
Trapezius Botox targets muscular bulk (muscle atrophy). Shoulder liposuction removes fat deposits. Most shoulder width is muscular, making Botox the preferred non-surgical option for shoulder slimming.
Yes. While more popular among women seeking a slimmer silhouette, men also benefit — particularly for tension headache relief and shoulder pain reduction associated with trapezius hypertonicity.
Yes. Many patients report significant reduction in chronic shoulder tension, neck stiffness, and tension headaches. The muscle relaxation relieves the chronic contraction pattern that causes myofascial pain.
Yes. You can fly immediately after treatment. There are no restrictions on travel. Many tourists get trapezius Botox during their Seoul trip and fly home the same day.
RE:BERRY Myeongdong recommends 3-4 sessions at 4-6 month intervals for optimal cumulative results. Each session produces greater and longer-lasting shoulder slimming.
Yes. By reducing the trapezius bulk that creates a sloped shoulder line, the neck appears elongated and the collarbone becomes more prominent. This is the primary aesthetic goal.
RE:BERRY Myeongdong uses KFDA-approved botulinum toxin brands including Nabota (Jeuveau), Xeomin, and Botulax. All products are genuine and sourced from authorized distributors.
Extremely popular. Known as “Barbie Botox” on social media, trapezius Botox has become one of Korea’s fastest-growing aesthetic treatments, especially among women aged 20-40.
Dr. Baek adjusts the unit dosage per side to correct asymmetry. More units for the larger trapezius, fewer for the smaller side. This personalized approach is standard.
Mild and temporary effects may include slight bruising at injection sites (fading in 3-5 days), temporary muscle soreness, and mild difficulty with heavy overhead lifting for 2-3 weeks.
The term “Barbie Botox” went viral on TikTok because the treatment creates a slim, elongated neck-shoulder line similar to a Barbie doll’s proportions. The clinical name is trapezius botulinum toxin injection.
It naturally wears off in 4-6 months. The muscle gradually regains its original size. This makes it a low-risk treatment with no permanent commitment.
Same mechanism (muscle atrophy via botulinum toxin), different muscles. Trapezius targets the upper trapezius for shoulder slimming; calf Botox targets the gastrocnemius for leg slimming. Both cost ₩79,000/100U at RE:BERRY Myeongdong.
Wear a top that exposes your shoulders and upper back — a tank top or off-shoulder top is ideal. This allows the doctor to properly assess and access the trapezius muscle.
No. Botulinum toxin is not recommended during pregnancy or breastfeeding. Wait until after breastfeeding is complete before scheduling treatment.
