Quick answer: Forehead wrinkles are usually treated with Botox, which relaxes the forehead muscle so lines soften in about one to two weeks. Deeper lines that stay when your face is relaxed may also need skin boosters, a small amount of soft filler or laser resurfacing. Most options have very little downtime.
Key takeaways
- Lines that appear when you raise your eyebrows are called dynamic wrinkles.
- Lines that stay at rest are static wrinkles and often need more than Botox.
- Botox is the main treatment and lasts about three to four months.
- Skin boosters and lasers improve skin quality and fine lines.
- A careful dose keeps natural eyebrow movement.
What causes forehead wrinkles?
The forehead muscle (frontalis) lifts the eyebrows. Each time you raise them, the skin folds. Over years, and as collagen decreases, these folds become lines that stay even when you relax. Sun exposure, dry skin and genetics also play a part.
Wrinkle treatments are among the most popular for visitors to Seoul. Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare.
Which treatments work best for forehead wrinkles?
1. Botox
Botox relaxes the forehead muscle so movement lines soften. Results start in three to seven days and last about three to four months. It is quick, with almost no downtime. See Botox in Gangnam for foreign patients and our Botox page.
2. Skin boosters
Boosters such as Rejuran, Skinvive or Juvelook improve hydration and thickness, so fine lines look softer. See Rejuran Healer in Korea and Skinvive in Korea.
3. Soft filler for deep static lines
A very small amount of soft HA filler can lift a deep line that stays at rest. This needs an experienced injector. See dermal fillers in Seoul.
4. Laser and energy treatments
Fractional lasers and radiofrequency improve skin texture and stimulate collagen, which helps fine lines over time. Lifting devices can also help if the brow has dropped. See our laser lifting page and Ultherapy Prime guide.
Which option is right for me?
- Lines only when you move: Botox.
- Lines at rest, thin skin: Botox plus skin boosters.
- One or two deep etched lines: Botox plus a tiny amount of soft filler.
- Heavy brows or drooping eyelids: be careful with forehead Botox. A doctor may suggest lifting instead.
How to keep a natural look
- Use a careful dose so you can still move your eyebrows a little.
- Treat the frown lines too, so the forehead and brow stay balanced.
- Tell the doctor if your eyelids feel heavy or your brows are low.

What is the downtime?
- Botox: small bumps for 15 to 30 minutes. Stay upright for four hours.
- Skin boosters: small bumps for one to two days.
- Filler: mild swelling for one to three days.
- Laser: redness for one to several days, depending on strength.
Most of these fit easily into a short trip. See same-day skin treatments in Seoul and low-downtime treatments before flying.
How long do results last?
Botox lasts about three to four months. Skin boosters last several months, often with a course of sessions. Filler for forehead lines often lasts 9 to 12 months. Regular sunscreen helps every result last longer.
Is it safe?
These are common treatments with mostly mild side effects. Too much forehead Botox can make the brows feel heavy for a few weeks. Forehead filler must be placed carefully because of blood vessels in the area. Choose an experienced doctor.
How to choose a clinic
- Ask which toxin brand and how many units will be used.
- Ask for a written quote and aftercare in English.
- Make sure the doctor who consults you also performs the treatment.
