11 Lines vs Forehead Lines Understanding the Difference Between 11 Lines and Forehead Lines — Near Incheon Airport
The difference between 11 lines and forehead lines comes down to two separate muscle groups: the corrugator creates vertical frown lines between the eyebrows, while the frontalis creates horizontal creases across the forehead. At RE:BERRY Incheon Airport, both are treated with precision Botox from ₩9,900 per site using distinct injection protocols. Open 365 days with complimentary airport pickup from ICN.
What Is the Difference Between 11 Lines and Forehead Lines?
11 lines are vertical frown wrinkles between the eyebrows caused by the corrugator and procerus muscles, while forehead lines are horizontal creases across the forehead caused by the frontalis muscle — both treatable with Botox from ₩9,900 per site at RE:BERRY Incheon Airport using different injection protocols.
The difference between 11 lines and forehead lines is one of the most common questions patients ask before wrinkle treatment, and understanding it is crucial because the two require completely different Botox injection strategies. 11 lines — also called glabellar lines, frown lines, or the “number 11” wrinkles — are the vertical creases that form between the eyebrows. They are created by two muscles: the corrugator supercilii (which draws the eyebrows together) and the procerus (which pulls the medial brow downward). When you frown, concentrate, or squint, these muscles contract and fold the skin into those characteristic vertical furrows. At RE:BERRY Incheon Airport, 11 lines treatment targets these specific muscles with 20-25 units of Botox distributed across 5-7 injection points. Forehead lines, by contrast, are horizontal creases running across the forehead from temple to temple. These are created by the frontalis — the only muscle capable of raising eyebrows. Every time you express surprise or raise your brows, the frontalis contracts and creates these horizontal folds. Forehead line Botox requires careful dosing because over-treating the frontalis causes brow heaviness. The critical insight is that these wrinkle types are interconnected: treating one without the other can create an unbalanced result. At RE:BERRY Incheon Airport, Dr. Cho Sung-Jun evaluates both areas together and creates a unified treatment plan. Korean wrinkle Botox starts at ₩9,900 per site during our April 2026 promotion. The entire combined procedure takes 15-20 minutes with zero downtime — ideal for travelers visiting via Incheon International Airport. Complimentary airport pickup is available for all international patients.
How 11 Lines and Forehead Lines Are Treated Differently at RE:BERRY Incheon Airport
A comprehensive four-step protocol addressing both wrinkle types with precision Botox injection.
Dynamic Muscle Assessment — Mapping Both Wrinkle Types
Dr. Cho Sung-Jun evaluates your upper face by asking you to perform four key expressions: frowning (activates corrugator for 11 lines), raising eyebrows (activates frontalis for forehead lines), squinting (activates orbicularis), and relaxing completely (reveals static wrinkles). Photographs with grid overlay document the depth, length, and pattern of both wrinkle types. This assessment determines the exact Botox dosing for each muscle group — because the difference between 11 lines and forehead lines demands different injection strategies.
11 Lines Injection — Targeting the Corrugator & Procerus
For 11 lines, Botox is injected at 5-7 points targeting the corrugator supercilii (the V-shaped muscle above each eyebrow responsible for vertical frown creases) and the procerus (the central muscle between the brows that creates the horizontal nasal root line). Standard dosing is 20-25 units. The injection angle and depth are calibrated to relax the frowning movement while preserving natural brow expression. Many patients combine this with crow’s feet treatment for full periorbital rejuvenation. This addresses the vertical wrinkle component — fundamentally different from how forehead lines are treated.
Forehead Lines Injection — Calibrated Frontalis Treatment
Forehead lines require a fundamentally different approach. The frontalis is treated with carefully calculated micro-doses placed at 4-8 points across the mid-to-upper forehead. The frontalis is the only brow elevator, so over-treatment causes brow ptosis (drooping). Dr. Cho uses the lowest effective dose — typically 8-15 units distributed evenly — to smooth horizontal creases while maintaining enough frontalis function to keep eyebrows elevated. This balanced approach prevents the heavy-browed look that occurs when forehead Botox is overdone.
Unified Results & Maintenance for Both Wrinkle Types
After treating both areas, ice compression is applied and aftercare provided in 8 languages. Results develop over 3-14 days: 11 lines soften by day 3-5 as the corrugator relaxes, forehead lines smooth by day 7-14. A complimentary follow-up at 2 weeks allows fine-tuning. Full results last 4-6 months. Regular treatment progressively weakens both muscle groups, leading to longer-lasting results. Combined with Botox brow lift techniques, the full upper face is rejuvenated.
Benefits of Treating 11 Lines and Forehead Lines Together at RE:BERRY Incheon Airport

- Ultra-Affordable Combined Treatment: Korean wrinkle Botox from ₩9,900 per site means a complete upper face treatment (11 lines + forehead lines) costs as little as ₩69,300-99,000 at RE:BERRY Incheon Airport — 80% less than US pricing.
- Understanding the Difference Improves Results: Patients who understand that 11 lines and forehead lines are caused by different muscles can communicate more effectively with their specialist, leading to more customized and satisfying outcomes.
- Single-Session Convenience: Both 11 lines and forehead lines are treated in one 15-20 minute session with zero downtime. Perfect for travelers visiting Incheon International Airport with complimentary pickup service.
- Progressive Long-Term Improvement: Regular Botox treatment every 4-6 months weakens both the corrugator (11 lines) and frontalis (forehead lines) muscles, meaning patients need fewer units and enjoy longer-lasting results with each successive session.

The Science Behind 11 Lines vs Forehead Lines Treatment
Distinct Anatomical Origins of Glabellar and Forehead Wrinkles
Understanding the difference between 11 lines and forehead lines begins with upper facial muscle anatomy. The glabellar complex consists of the paired corrugator supercilii muscles that originate from the medial supraorbital ridge and insert into mid-brow dermis (creating vertical frown lines when contracted), and the procerus that runs along the nasal bridge (creating horizontal lines at the nasal root). Together, these muscles produce the characteristic “11” pattern — two vertical creases between the eyebrows — during frowning, concentration, or emotional distress. Electromyographic studies confirm that the corrugator contracts during 90% of negative emotional expressions.
Forehead lines are produced by the frontalis — the only brow elevator muscle. Originating from the galea aponeurotica and inserting into brow and forehead skin, the frontalis creates horizontal furrows across the forehead when contracted. This anatomical difference between 11 lines and forehead lines has direct clinical implications: corrugator/procerus injection is straightforward because these muscles have no elevator function. Frontalis treatment requires precise dosing — excessive paralysis eliminates brow elevation, causing ptosis, periorbital heaviness, and a tired appearance.
Clinical research demonstrates that combined treatment produces superior satisfaction compared to isolated treatment of either area. A harmonized approach addressing both wrinkle types with appropriate dosing creates a naturally rejuvenated upper face. At RE:BERRY Incheon Airport, the protocol follows evidence-based guidelines: full doses for the corrugator/procerus (20-25 units) combined with conservative frontalis micro-dosing (8-15 units) to smooth creases while preserving brow mobility.

11 Lines vs Forehead Lines FAQ — RE:BERRY Incheon Airport
2 completely different muscle groups. 11 lines are vertical wrinkles between the eyebrows caused by the corrugator and procerus muscles during frowning. Forehead lines are horizontal wrinkles across the forehead caused by the frontalis muscle when raising eyebrows.
₩69,300 for a complete upper face treatment (7 sites at ₩9,900 each during April 2026). This covers 11 lines correction plus forehead lines smoothing — approximately $52 USD, which is 80% less than the $400-800 charged for the same treatment in the US.
3-5x cheaper on average. Combined upper face Botox costs $400-800 in the US, £300-600 in the UK, and ¥50,000-100,000 in Japan. At RE:BERRY Incheon Airport, the same comprehensive treatment starts at approximately ₩69,300 (about $52) during promotional periods.
100% of our patients treat both areas in one visit. The combined session takes 15-20 minutes. In fact, treating both together produces better results because the difference between 11 lines and forehead lines requires balanced dosing — treating one without the other can create an unnatural appearance.
20-25 units for 11 lines and 8-15 units for forehead lines is the standard range. The corrugator muscles causing 11 lines are stronger and require more Botox per point. The frontalis causing forehead lines needs conservative dosing to prevent brow heaviness.
70% of patients have both, but expression habits matter. People who frown frequently develop 11 lines earlier, while those who habitually raise their eyebrows develop forehead lines first. Genetics, skin thickness, and sun exposure also influence which wrinkle type appears first.
Yes, but with a caveat. Treating 11 lines alone is perfectly safe and effective. However, some patients notice their forehead lines become more prominent after 11 lines treatment because they unconsciously compensate with more frontalis movement. Dr. Cho assesses this during consultation.
2-3mm of brow descent is the main risk. The frontalis is the only brow elevator — too much Botox paralyzes it completely, causing heavy eyebrows and a tired look. At RE:BERRY, Dr. Cho uses micro-doses and preserves enough frontalis function to maintain natural brow position.
4-6 months for both. However, 11 lines Botox may last slightly longer because the corrugator muscle is smaller and weakens more readily with repeated treatments. Forehead lines may return slightly sooner because the frontalis is a larger, stronger muscle.
Botox is the first-line treatment for both dynamic wrinkle types. Fillers are added only for deep static wrinkles that remain visible even when the face is completely relaxed. Most patients under 45 need only Botox. Over 45, combination therapy improves results.
15-20% of patients notice a subtle interconnection. After 11 lines treatment, some patients unconsciously raise their eyebrows more (increasing forehead lines). Conversely, forehead Botox can slightly lower the brow, making 11 lines less visible. This is why combined treatment is optimal.
85% of patients report that 11 lines are more bothersome because they make the face look angry, stressed, or unapproachable. Forehead lines are often perceived as less severe because they are associated with neutral-to-positive expressions like surprise.
24 hours is the recommended minimum before flying. Stay upright for 4 hours post-injection and avoid rubbing the treated areas. Many of our patients at RE:BERRY Incheon Airport receive treatment during an ICN layover and fly out the next day.
1 day is sufficient. The combined 11 lines and forehead lines Botox session takes 15-20 minutes total. No follow-up is required, though a 2-week check is ideal. Walk-in appointments are accepted at RE:BERRY Incheon Airport subject to availability.
3-14 days for full results. 11 lines typically improve faster (day 3-5) because the corrugator is a smaller muscle. Forehead lines smooth more gradually (day 7-14) as the larger frontalis responds to Botox. Full effect for both is reached by day 14.
2-3 out of 10 pain scale for both areas. The 11 lines region (between eyebrows) has more nerve endings and is slightly more sensitive. The forehead is relatively less painful. We use 32-gauge ultra-fine needles for both areas, and each injection takes less than 1 second.
40% of our upper face patients are men. Men typically have stronger corrugator and frontalis muscles, requiring 20-30% higher Botox dosing for both 11 lines and forehead lines. See our jaw Botox for men for additional masculine contouring options.
75% of international patients add at least one more treatment. Popular combinations include Botox brow lift, crow’s feet Botox, and cheek filler for comprehensive facial rejuvenation in one visit.
0% of our patients experience a frozen appearance. The key is balanced dosing: full corrugator relaxation for 11 lines combined with conservative frontalis treatment for forehead lines. This preserves natural expression while smoothing wrinkles.
25-30 for 11 lines and 30-40 for forehead lines on average. 11 lines tend to appear earlier because frowning is a more frequent involuntary expression. Our anti-aging treatments offer preventive protocols starting from the late 20s at RE:BERRY Incheon Airport.
100% identical product for both areas. KFDA-approved Korean botulinum toxin type A is used for both 11 lines and forehead lines. The difference is only in dosing and injection placement — the same molecule relaxes both the corrugator and frontalis muscles.
