Forehead lines are among the most common facial aging concerns — and often the first area patients want treated. When horizontal forehead lines deepen into static wrinkles, the resting face appears worried or serious even in a relaxed state. At Rappoel Dermatology in Seoul, we use Coretox (by Medytox, Korea) with a carefully calibrated, expression-preserving injection philosophy — the goal is to look younger, not frozen.
Why Forehead Lines Deepen
- Repetitive frontalis contraction: Every eyebrow raise creates a skin fold; over years, these become permanent lines
- Collagen loss: After age 30, reduced skin elasticity converts dynamic into static lines
- Compensatory brow raising: Patients with mild eyelid heaviness unconsciously elevate their brows to open the visual field, increasing frontalis use
- Photoaging: UV exposure accelerates line formation and skin texture degradation
Rappoel’s Forehead Injection Design Principles
The key challenge in forehead botulinum treatment is dosage balance — too much causes expressionless forehead or brow ptosis (the most common adverse effect); too little yields inadequate results.
- Brow-position-customized dosing: Patients with naturally lower brows receive conservative doses to prevent further descent
- Multi-point distributed injection: Even coverage with preserved expression movement at key points
- Concurrent glabellar assessment: Corrugator/procerus (frown line) tension affects frontalis compensation — recommended to evaluate together
What Coretox Forehead Treatment Improves
- Dynamic forehead lines (lines that appear when raising the brows)
- Static lines (visible at rest) — improvement varies by depth; deep lines may benefit from adding HA filler
- Smoother, more refined forehead texture overall
