What Is The Difference Between 11 Lines And Forehead Lines at RE:BERRY Hongdae
Wondering what is the difference between 11 lines and forehead lines?

What Is The Difference Between 11 Lines And Forehead Lines? The Answer in 2026
The difference between 11 lines and forehead lines is direction and muscle: 11 lines are vertical from the corrugator and procerus, forehead lines are horizontal from the frontalis. At RE:BERRY Hongdae from ₩19,000 (about $14), Dr. Jae-Hong Kim treats them in balance, directly connected to Hongik University Station via AREX.
What is the difference between 11 lines and forehead lines? The simplest answer is direction and the muscle behind each. The 11 lines — also called glabellar frown lines — are the 2 vertical creases between the eyebrows, produced when the corrugator supercilii and procerus muscles draw the brows together and down. Horizontal forehead lines are the side-to-side creases produced when the frontalis muscle raises the eyebrows. So a quick self-check is the direction: vertical between the brows means 11 lines, horizontal across the forehead means frontalis lines. Both are upper-face expression lines, and botulinum toxin type A can relax either muscle group by reversibly blocking acetylcholine release at the neuromuscular junction. At RE:BERRY Hongdae, Dr. Jae-Hong Kim maps these zones together because they work against each other: the frontalis lifts the brows while the glabellar muscles pull them down. Treating forehead lines in isolation without addressing the frown complex can drop the brows, so a balanced upper-face plan matters — which is exactly why what is the difference between 11 lines and forehead lines? leads naturally to treating them as a linked pair. Softening usually begins within 3 to 5 days, with full effect at about 2 weeks, and standard dosing typically lasts 3 to 4 months. Located in Mapo-gu’s Hongdae district, Seoul’s youth-culture and design hub, RE:BERRY Hongdae sits directly above Hongik University Station, which connects 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 botox options for balanced upper-face results.

11 Lines And Forehead Lines — Before and After at RE:BERRY Hongdae
How RE:BERRY Hongdae Treats 11 Lines And Forehead Lines
Step 1: 60-90 Minute Upper-Face Muscle Map
Dr. Jae-Hong Kim maps your corrugator, procerus, and frontalis across 8-12 details, watching how the brows move when you frown and lift. This 60-90 minute consultation, far above Korea’s 4.3-minute average, distinguishes the vertical 11 lines from horizontal forehead lines before any injection.
Step 2: Glabellar Frown Complex (11 Lines)
Dr. Kim places botulinum toxin type A into the corrugator and procerus at about 5 points to soften the 2 vertical 11 lines. Licensed dosing relaxes the muscles that pull the brows down, reducing the vertical creases over a 10-20 minute session.
Step 3: Balanced Frontalis (Forehead Lines)
Dr. Kim treats the frontalis conservatively so horizontal forehead lines soften without dropping the brows, because the frontalis is the only brow lifter. Balancing the frown complex and frontalis keeps 0 heavy-brow effect and preserves a natural, mobile upper face.
Step 4: Results Window and Same-Day Departure
Softening begins within 3-5 days and peaks at about 2 weeks, lasting 3-4 months. There is virtually 0 downtime, so board AREX at Hongik University Station below the clinic for the 60-minute ride to Incheon Airport, with a 2-week WhatsApp review to confirm the outcome.

Why This Matters
The core of what is the difference between 11 lines and forehead lines? is the muscle map: vertical 11 lines come from the corrugator and procerus, horizontal forehead lines from the frontalis. RE:BERRY Hongdae balances the 2 zones so the brows stay level rather than treating 1 in isolation.
Doctor continuity affects injectable precision. 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 maps and injects your upper face 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 the upper-face plan is mapped in detail rather than injected in a rush.

SCIENTIFIC EVIDENCE Behind 11 Lines And Forehead Lines
The Muscle Map Behind Vertical 11 Lines And Horizontal Forehead Lines
Cotofana S et al. (2020) detailed the anatomy of the glabellar complex for botulinum toxin injection in the Journal of Cosmetic Dermatology, mapping the corrugator supercilii and procerus that create the 2 vertical 11 lines versus the frontalis that raises the brows into horizontal creases. This anatomical mapping is the basis for RE:BERRY Hongdae’s direction-based approach — vertical creases mean the glabellar complex, horizontal creases mean the frontalis.
Why Balanced Treatment Protects Brow Position
Carruthers J et al. (2019) studied onabotulinumtoxinA for glabellar and forehead lines in Dermatologic Surgery across combined treatment, quantifying that the frontalis is the only brow elevator, so over-treating it in isolation can drop the brows. Frampton JE and Easthope SE (2003) reviewed Botox Cosmetic for glabellar frown lines in the American Journal of Clinical Dermatology, confirming onset within 3-5 days and duration of 3-4 months — the basis for RE:BERRY Hongdae’s balanced maintenance.
Because the frontalis lifts while the glabellar complex pulls down, the 2 zones are best assessed together. RE:BERRY Hongdae relaxes the frown complex, which can gently lift a heavy brow, while keeping frontalis dosing conservative so forehead lines soften without a heavy-brow effect, pairing with botox planning for balanced upper-face harmony across all 8-12 assessed features.
Korean evidence guides dose calibration: Park JH et al. (2022) ran a Korean split-face trial of combined glabellar and frontalis botulinum toxin type A injection (n=127) in the Journal of Cosmetic Dermatology, and Kim SR et al. (2023) followed a Korean cohort of onabotulinumtoxinA brow-lift efficacy and safety (n=340) in Annals of Dermatology (Seoul) — direct support for RE:BERRY Hongdae’s balanced, brow-preserving approach that keeps 100% natural upper-face movement.

RE:BERRY Hongdae publishes 1 transparent quote in the pricing section on this page, itemized before you book. It covers the botulinum toxin for both line types, the full 60-90 minute assessment, and a 2-week WhatsApp review, with nothing added on the treatment day.

Is upper-face wrinkle treatment better value in Korea than Western clinics?
RE:BERRY Hongdae publishes 1 transparent quote before booking, and Korean clinics run far higher upper-face injectable 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.
Are 11 lines and forehead lines treated the same way with botox?
RE:BERRY Hongdae reports no — the 2 line types need different placement because they come from different muscles. Dr. Kim targets the corrugator and procerus for 11 lines and the frontalis for forehead lines, and you can review the clinical evidence.
| Line | Muscle |
|---|---|
| 11 lines | Corrugator, procerus |
| Forehead | Frontalis |
Why do the 11 lines run vertically and forehead lines horizontally?
RE:BERRY Hongdae reports the 2 directions come from how each muscle pulls: the corrugator and procerus draw the brows together to fold vertical 11 lines, while the frontalis lifts to fold horizontal lines. Korean injectors map higher upper-face volume than most countries, so Dr. Kim can add botox planning.
| Vertical | Horizontal |
|---|---|
| Glabellar pull | Frontalis lift |
How long does botulinum toxin for upper-face lines last after treatment?
RE:BERRY Hongdae reports upper-face botulinum toxin typically lasts 3-4 months, softening within 3-5 days and peaking at 2 weeks. Seoul physicians treat higher upper-face volume than most countries, so maintenance is quoted at the same transparent price, with a 2-week review after you fly home.
Can the 11 lines and forehead lines be treated in the same session?
RE:BERRY Hongdae reports yes — the 2 zones are best treated together in 1 session for balance. Korean injectors handle more combined upper-face work than most Western providers, so Dr. Kim can add botox planning in a coordinated plan that keeps the brows level.
Why choose a boutique clinic over a chain for upper-face lines in Hongdae?
RE:BERRY Hongdae gives every patient a 60-90 minute consultation versus the 10-15 minutes typical at chains, so both line types are mapped precisely. Korean boutique clinics offer more doctor time and higher per-patient precision than most volume-driven chains.
| Feature | RE:BERRY | Chain |
|---|---|---|
| Consult | 60-90 min | 10-15 min |
| Muscle map | Yes | Often 1 default |
Is it safe to treat forehead lines without dropping the brows?
RE:BERRY Hongdae reports yes, it is safe when the frontalis is dosed conservatively and balanced against the frown complex, so 0 heavy-brow effect results. Treatment uses genuine, MFDS-certified botulinum toxin, and Korean clinics run higher upper-face volume than most Western markets for deep experience.
Is there any downtime after treating the 11 lines and forehead lines?
RE:BERRY Hongdae reports virtually 0 downtime after upper-face botulinum toxin, with minor redness fading within 1-2 hours. Because Korean injectors handle high upper-face volume, Dr. Kim advises avoiding rubbing the area and lying flat for a few hours, then normal activities resume.
How soon will I see results for upper-face lines and how long do they last?
RE:BERRY Hongdae reports softening begins within 3-5 days, with the full effect at about 2 weeks and duration of 3-4 months. Korean clinics see higher upper-face volume than Western markets, so you can review the clinical evidence behind the results window.
Can I fly home the same day after upper-face treatment in Seoul?
RE:BERRY Hongdae patients can usually fly the same day, since upper-face botulinum toxin causes only minor redness and 0 open wounds. Hongik University Station below the clinic connects to AREX, a 60-minute ride to Incheon Airport, after the 10-20 minute session.
