Scar Revision in Seoul: Laser, Injection and Surgical Options
The short answer
Scar revision in Seoul improves the color, texture, height and visibility of a scar using lasers, injections, subcision or surgical excision, but it cannot erase a scar completely. Laser sessions in Gangnam typically cost about ₩150,000–₩500,000 each, most scars need 3–6 sessions spaced 4–6 weeks apart, and surgical revision usually means 5–7 days of stitches before you can fly comfortably.

What scar revision can and cannot do
Every scar is the skin's permanent repair of an injury. Revision does not turn it back into untouched skin. What it can do is make the scar flatter, narrower, closer in color to the surrounding skin and less obvious in normal light. For many patients that is the difference between a mark they think about every day and one they rarely notice.
Seoul dermatology clinics treat a wide range of scars: rolling and boxcar acne scars, flat surgical lines, raised hypertrophic scars, keloids, and red or brown marks left after inflammation. The right method depends on which of these you have, so the first step is always an in-person assessment.
Matching the method to the scar
| Scar type | Common approach in Seoul | Typical sessions |
|---|---|---|
| Acne scars (rolling, boxcar) | Fractional laser, RF microneedling, subcision | 3–6 |
| Raised or hypertrophic scars | Steroid injection, vascular laser | 3–5 |
| Keloids | Injections, sometimes excision plus follow-up therapy | Ongoing |
| Red or brown marks | Vascular laser, pico or toning laser | 3–5 |
| Wide or poorly placed surgical scars | Surgical excision and re-closure | 1 procedure |
Laser resurfacing
Fractional lasers create tiny columns of controlled injury that prompt the skin to rebuild collagen, softening uneven texture over several sessions. You can read more on our fractional laser guide and the dedicated acne scar laser page.
Injections and subcision
Diluted steroid injections flatten thick, itchy scars. Subcision uses a fine needle to release the fibrous bands that pull rolling acne scars downward; it is often paired with laser for a stronger combined effect. See our page on scar subcision.
Surgical revision
For a wide, stretched or badly angled scar, a doctor may cut out the old scar and close the wound in finer layers, sometimes changing its direction so it sits in a natural skin crease. This is more involved and needs stitch removal around day 5–7.
Cost of scar revision in Seoul
Prices vary with the size of the area and the technique. As a rough guide, Gangnam clinics typically quote about ₩150,000–₩500,000 per laser session, ₩30,000–₩100,000 per steroid injection visit, ₩200,000–₩600,000 for subcision of a facial area, and from about ₩500,000 to ₩2,000,000 or more for surgical excision depending on length and location. Packages of several sessions are common; ask what is included and whether follow-up visits are charged.
Planning scar treatment from abroad
Because most scars need repeated sessions, a single short trip rarely completes treatment. Many international patients do one or two sessions in Seoul, then continue with a dermatologist at home, or schedule return visits every one to two months. Ask the clinic for written settings and a treatment summary so another doctor can continue the plan.
- Laser downtime is usually 2–7 days of redness, crusting or mild swelling.
- Avoid sun exposure and use SPF 50 for several weeks; healing skin pigments easily.
- Surgical revision needs stitch removal before you fly, so allow at least a week.
- Keloid-prone patients should mention it at the start; surgery alone can make keloids return.
How to choose a clinic
Look for a clinic where a dermatologist or plastic surgeon examines the scar personally and explains why a specific method suits it. Ask how many sessions they expect, what improvement is realistic for your scar type, which devices they use, and whether an English-speaking coordinator will be present at every visit. Photos taken under consistent lighting at each session help you judge progress honestly. For clinic options, our overview of acne scar treatment clinics in Gangnam is a useful starting point.

Patient questions
Frequently asked questions
Can a scar be removed completely?
No. Revision makes a scar less visible by improving its color, texture and width, but some trace always remains.
How soon after an injury or surgery can I treat a scar?
Lasers for redness can start a few weeks after the wound has closed; surgical revision is usually delayed until the scar has matured, often 6–12 months.
Is scar laser painful?
Numbing cream is applied for 30–60 minutes, after which most people describe a hot, prickling sensation that is tolerable.
Can I treat old acne scars in one trip?
You can start in one trip and may see some softening, but noticeable improvement usually takes 3–6 sessions over several months.
Are keloids treated differently?
Yes. Keloids are usually managed with injections and close follow-up, because cutting them out alone often triggers regrowth.
