Glabellar lines are the vertical lines between the eyebrows — typically two to three lines, also called frown lines or anger lines. With habitual frowning, the corrugator and procerus muscles in the glabellar area repeatedly contract, forming dynamic wrinkles; with age, collagen loss and reduced skin elasticity gradually solidify dynamic wrinkles into static wrinkles — visible even without frowning. Glabellar lines make people look tired, angry, or anxious — feeling perfectly fine but being misread as ‘are you angry?’ due to frown lines. Causes: (1) Expression habits — habitual frowning, squinting, unconscious frowning during concentration is the main cause. (2) Aging — collagen loss, thinner skin, deepening wrinkles. (3) Photoaging — UV damages collagen and elastic fibers, accelerating wrinkle formation. (4) Genetics — some people naturally have expressive faces with earlier frown lines. Rappoel Dermatology near Gangnam Station, Seoul, uses Coretox — precise injection into the corrugator and procerus muscles to relax overactive glabellar muscles, with a 5-minute treatment and visible frown line smoothing within a week.
Technical Advantages of Coretox Glabellar Treatment
- Precise relaxation of glabellar muscles: After injection into the corrugator and procerus, Coretox blocks neuromuscular signaling, relaxing overactive muscles — frowning amplitude reduces or disappears, smoothing frown lines
- Coretox Korean-origin high-purity advantage: Coretox is 150kDa high-purity toxin with complex proteins removed, reducing antibody and resistance risk. Facial expression areas require precise control — high-purity formulation spreads less, reducing risk of spreading to surrounding muscles like the orbicularis oculi causing stiffness
- Fast onset (2-3 days): Coretox clinical data shows average onset of 2-3 days — glabellar muscles begin relaxing at 3-5 days, frown lines visibly smooth at 5-7 days, optimal at two weeks
- Treatment + prevention dual effect: Coretox not only smooths existing frown lines — with muscle relaxation, frowning decreases, preventing dynamic wrinkles from deepening and delaying static wrinkle formation. Earlier treatment yields better results
- Minimally invasive with no recovery: Only 5-7 injection points, completed in 5 minutes — pinholes close in 1 day, no surgery or recovery, doable on a lunch break
Treatment Strategies for Different Glabellar Issues
- Dynamic frown lines (early): Clear lines when frowning, smooth skin at rest. Strategy: Coretox 20-30 units in 5 points — corrugator (2 per side) + procerus (1), lines disappear when frowning after relaxation
- Static frown lines (moderate to advanced): Lines visible without frowning, skin has developed furrows. Strategy: Coretox 20-30 units to relax muscles + HA filler for furrows — Botox prevents deepening, HA fills existing furrows, combination is optimal
- Glabellar + forehead lines combination: Frown lines with horizontal forehead lines. Strategy: corrugator Coretox 20-30 units + frontalis Coretox 10-20 units (6-10 points) — improving both glabella and forehead; frontalis dose must be controlled to avoid brow droop
- Glabellar + crow’s feet combination: Frown lines with lateral eye wrinkles. Strategy: corrugator Coretox 20-30 units + lateral orbicularis oculi Coretox 10-20 units (2-3 points per side) — improving both areas
- Brow-heavy-eye type: Drooping brows pressing the eyes with prominent frown lines. Strategy: beyond corrugator relaxation, inject a small amount of Coretox (10-15 units) into the frontalis above the brow margin for a slight brow lift — improving both brow heaviness and frown lines
Rappoel Glabellar Coretox Injection Treatment Protocol
- Glabellar assessment and plan design (5 min): Patient frowns to assess dynamic lines → assess static lines at rest → check glabellar muscle mobility → photograph → establish injection plan (dosage, points)
- Disinfection preparation (2 min): Glabellar cleansing → alcohol swab disinfection → mark 5 injection points (2 per corrugator, 1 procerus, in the safe glabellar zone, avoiding vessels above the orbital rim)
- Precise injection (3-5 min): 32G ultra-fine needle → 4-6 units Coretox per point → intramuscular injection depth → total 20-30 units → gentle pressure after injection
- Immediate assessment and guidance (3 min): Patient frowns to confirm reduced muscle activity → post-care instructions (avoid lying flat and massaging for 4 hours, avoid strenuous exercise for 24 hours, avoid high-heat environments for 1 week, avoid testing by frowning) → 2-week follow-up
The glabellar Coretox injection takes about 10 minutes, with onset at 2-3 days, visible smoothing at 5-7 days, lasting 3-4 months. Located 3 minutes from Gangnam Station Exit 10, with seamless English and Chinese consultation.
Frequently Asked Questions
How long do Coretox glabellar results last? How often do I need injections?
Coretox glabellar treatment typically lasts 3-4 months — glabellar muscles are frequently active (frowning, squinting, expressions), with relatively fast neuromuscular junction regeneration. Rappoel recommends: injection every 3-4 months for maintenance. Benefits of regular treatment: (1) Continuous suppression of frowning prevents dynamic lines from deepening. (2) After prolonged relaxation, baseline muscle tone decreases, allowing some patients to extend to 4-5 month intervals. (3) Starting regular treatment earlier delays static wrinkle formation. Patients with prominent static lines should consider Botox + HA filler combination.
Will Coretox for frown lines cause stiffness or look overdone?
With proper dosing there’s no stiffness or overdone look — the key is dose and placement control: (1) Dose — standard glabellar dose is 20-30 units, only relaxing the corrugator and procerus without affecting other expression muscles. (2) Placement — Rappoel precisely injects the glabellar muscles, avoiding the orbital rim and orbicularis oculi, preserving blinking and eye expression. (3) Effect — after proper treatment, frowning is weakened but other expressions (smiling, blinking, raising brows) remain completely normal — you just ‘can’t frown,’ looking more relaxed and approachable. (4) Overdose risk — if excess spreads to the orbicularis oculi, temporary stiffness may occur, resolving naturally in 4-6 months. Rappoel starts standard, preferring under-treatment.
Does Coretox help with static frown lines (visible without frowning)?
It helps, but combination may be needed: (1) Pure dynamic lines (only when frowning) → Coretox alone works best. (2) Mild static lines (subtle at rest) → after muscle relaxation, static lines visibly improve — because static line maintenance relates to sustained muscle contraction; once relaxed, skin naturally unfolds. (3) Severe static lines (clear furrows) → Coretox alone has limited effect; recommend Coretox + HA filler: Coretox prevents frowning from deepening furrows, HA fills existing furrows — complementary, far better than single treatment. Rappoel assesses static line depth during consultation to recommend the best combination.
How fast does glabellar Botox work? When is the effect most visible?
Coretox glabellar timeline: (1) 2-3 days — onset begins, weaker muscle force when frowning. (2) 5-7 days — frown lines visibly smooth, frowning amplitude significantly reduced. (3) 2 weeks — optimal results, dynamic lines essentially gone, static lines clearly improved. (4) 3-4 months — effect gradually diminishes, muscle activity returns, re-injection possible. Note: avoid lying flat or massaging for 4 hours after injection (prevent medication migration); avoid testing by frowning for 1 week (accelerates metabolism). For optimal state before important events (photoshoots, activities), inject 2 weeks in advance.
How does Coretox differ from other brands for frown lines?
Key differences between Coretox and other brands: (1) Purity — Coretox is 150kDa high-purity toxin with complex proteins removed; Botox is 900kDa complex. Purity affects antibody risk. (2) Onset speed — Coretox averages 2-3 days; others typically 5-7 days. Patients wanting fast improvement before important events choose Coretox. (3) Diffusion — Coretox spreads less, more precise in delicate expression areas like the glabella, reducing risk of spreading to the orbicularis oculi causing stiffness or brow droop. (4) Formulation — no animal-derived proteins or albumin, lower allergy risk. (5) Dose — Coretox and Botox are essentially 1:1, both 20-30 units for frown lines. Duration similar (3-4 months). Rappoel selects based on patient needs, recommending Coretox for fast onset and precise control.
