Deep Forehead Lines Making You Look Stern or Stressed? Coretox Forehead Wrinkle Treatment at Rappoel Seoul



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

Frequently Asked Questions

Will my eyebrows drop after forehead botulinum treatment?
Brow ptosis is the most common forehead botulinum side effect, typically caused by injecting too low or using too much volume. Rappoel customizes dosing for each patient’s brow position — conservative amounts for patients with naturally lower brows significantly reduce this risk.
How long does forehead treatment last for first-time patients?
Typically 4–5 months initially. With regular maintenance, the frontalis muscle weakens progressively, and subsequent treatments can last 6 months or longer.
My forehead lines are very deep — is botulinum enough?
For deep static wrinkles, botulinum toxin addresses the dynamic component; the static groove often benefits from adding hyaluronic acid filler. Combined treatment gives the most complete result.
Can forehead and frown lines be treated in the same session?
Yes, and it’s strongly recommended. Corrugator tension influences how much the frontalis compensates — designing both areas together creates more harmonious, natural results.
When can I apply makeup after treatment?
Wait at least 4 hours before applying makeup to avoid pressing or rubbing the injection sites. Normal face washing is fine the same day, using gentle pressure.
