Why Forehead Lines Form — and Why Botulinum Toxin Works
Forehead wrinkles are caused by the frontalis muscle repeatedly lifting the eyebrows, combined with age-related loss of collagen and skin elasticity. There are two key types:
- Dynamic lines: Only appear with facial expression — ideal for botulinum toxin alone
- Static lines: Visible even at rest — benefit from botulinum toxin + filler or skin booster combination
Coretox blocks nerve signals that trigger muscle contraction, allowing the skin to naturally smooth out over 3–7 days post-treatment.
Why Rappoel Uses Coretox for Forehead Lines
Coretox by Medytox is one of the few botulinum toxin products formulated without human serum albumin, using recombinant human albumin instead. Key advantages for forehead treatment:
| Feature | Coretox | Conventional Toxins |
|---|---|---|
| Stabilizer | Recombinant albumin | Human serum albumin |
| Batch consistency | High | Moderate |
| Duration | 4–6 months | 3–5 months |
| Diffusion | Low (more precise) | Moderate |
The Procedure: 30 Minutes Start to Finish
- Consultation (10 min): Doctor assesses muscle strength, wrinkle depth, eyebrow position, marks injection points
- Prep (5 min): Skin cleanse and optional topical numbing cream
- Injection (10 min): Fine-needle injection at 4–8 precisely mapped points
- Aftercare briefing (5 min): Instructions on what to avoid for the next 4 hours
Results appear within 3–7 days, peak at 2 weeks, and typically last 4–6 months.
Coretox vs Filler for Forehead Wrinkles
- Coretox: Best for dynamic wrinkles and prevention — first-line treatment
- HA Filler: Physically fills deep static grooves — for established sunken lines
- Combination: Coretox + small filler deposit addresses both dynamic and static components
Aftercare Guidelines
- Avoid pressing the injection area for 4 hours post-treatment
- Skip strenuous exercise, saunas, and high heat on the day of treatment
- Return for 2-week follow-up; touch-up if needed
- Mild eyebrow heaviness (rare) typically resolves within 2–4 weeks
