Forehead Wrinkle Treatment in Seoul – Diagnosis by Board-Certified Dermatologists
Forehead wrinkles are horizontal lines across the forehead caused mainly by repeated eyebrow raising, plus collagen loss and sun damage over time. At The Heal Dermatology Sinsa Main Branch in Gangnam, Seoul, board-certified dermatologists assess muscle activity and brow position and may combine Botox, skin boosters or fillers to soften lines naturally.

What causes forehead wrinkles
The frontalis muscle lifts the eyebrows. Frequent raising, sometimes to compensate for heavy eyelids, creates dynamic lines that become permanent as skin thins and loses collagen. Sun exposure, genetics and dry skin contribute, and lines often become more noticeable from the 30s onwards.
How a dermatologist diagnoses it
A dermatologist checks lines at rest and while raising the brows, assesses brow and eyelid position, and looks at skin quality. This is important because relaxing the forehead too much in someone who relies on it to lift heavy lids can cause brow heaviness.
Treatment options at The Heal Sinsa
Dynamic lines are commonly treated with Botox using carefully placed, conservative doses. Etched static lines may also benefit from skin boosters, Rejuran or small amounts of filler. Availability of specific devices varies by branch – confirm at consultation. Every plan starts with a 1:1 consultation with a Korean board-certified dermatologist and imaging-based skin analysis; you will not be pushed toward treatment you do not need. Pricing is confirmed after consultation; see pricing and payment.
Sessions, downtime & side effects
- Botox takes effect in about 3–7 days, peaking around 2 weeks
- Results typically last 3–4 months
- Possible side effects: bruising, headache, brow heaviness or asymmetry
- Avoid during pregnancy, breastfeeding or with certain neuromuscular conditions
Home care
Wear sunscreen and sunglasses to reduce squinting, keep skin moisturised and consider a retinoid at night. After Botox, avoid rubbing the area or lying flat for a few hours as advised.
When to see a doctor
See a dermatologist if lines are deepening, if you notice you raise your brows constantly, or if you have had brow drooping after previous injections and want a more careful plan.
Planning around your trip to Seoul
Schedule Botox early in your trip so results appear and any adjustment can be checked before you fly; see flying after Botox. The clinic is on the 7th floor of Sinsa Square near Sinsa Station, close to Garosu-gil (getting here), and English support is available on request (international patients).

Frequently asked questions
Can Botox cause droopy eyebrows?
It can if the forehead muscle is over-relaxed, especially in people who use it to lift heavy eyelids. Careful assessment and conservative dosing reduce this risk. Any heaviness is temporary and fades as the effect wears off.
How long does forehead Botox last?
Results typically last around three to four months, sometimes longer with regular treatment. Duration varies with dose, metabolism and muscle strength. Your dermatologist will suggest a sensible interval for repeat treatment.
Can deep forehead lines be fully removed?
Botox softens movement lines well, but deep etched lines may not disappear completely. Combining Botox with skin boosters or fine filler can improve them further over time. Your dermatologist will set realistic expectations.
