Scars come in several types, so improvement usually needs a plan matched to the scar (fractional laser, subcision) over 3 or more sessions rather than one universal treatment.
Scar treatment in Gangnam, Seoul is matched to the scar type: fractional laser resurfaces and remodels acne and surface scars, while subcision releases tethered rolling scars from below. Most plans combine methods over a series of sessions. At our Gangnam (Seoul) location, Dr. Yoongon Ryu assesses your scars in English before building a plan.

Scar treatment in Gangnam, Seoul starts with identifying the scar type, because scars are not all the same and do not respond to one universal method. Atrophic acne scars, the most common concern, are usually grouped into ice-pick, boxcar, and rolling scars, each with a different depth and shape. There are also raised scars and post-inflammatory marks. A quality clinic first classifies your scars, then selects and combines treatments accordingly, rather than passing every scar under the same laser.
Two workhorses anchor most plans. Fractional laser creates thousands of microscopic treatment columns that trigger controlled healing and new collagen, remodelling scarred skin over a series of sessions; it suits surface texture, boxcar, and mixed acne scarring. Subcision uses a fine needle or cannula to release the fibrous bands that tether rolling scars to deeper tissue, allowing the depression to lift. Because scars often coexist, doctors frequently combine subcision with fractional laser, and may add supportive treatments, to address both the tethering and the surface texture.
At Reberry Clinic, scar care is consultation-led and delivered in English. At our Gangnam (Seoul) location, Dr. Yoongon Ryu grades your scar types and depth, then sequences fractional laser, subcision, and supportive care into a realistic, multi-session plan. Gangnam is easily reached (Seocho, about 2 minutes from Gangnam Station exit 10), and international patients are supported across our three Seoul-area locations.
Scar improvement works by prompting the skin to remodel disorganised scar tissue, and different tools reach different depths. Fractional laser, whether ablative CO2 or non-ablative, delivers energy in a grid of microscopic columns that spare surrounding skin, so healing is faster than fully ablative resurfacing while still stimulating new collagen; most acne-scar courses run about 3 to 5 sessions spaced 4 or more weeks apart. It is well suited to surface texture, boxcar scars, and mixed scarring. Subcision addresses a mechanical problem fractional laser cannot: rolling scars are pulled down by fibrous bands, so a fine needle or blunt cannula is passed under the scar to cut those bands, releasing the depression and encouraging new collagen to fill the space. Because rolling and boxcar scars often coexist, subcision and fractional laser are frequently combined in the same plan, with studies of laser-assisted subcision reporting large improvements on validated scar scales. The doctor sequences and spaces these based on scar type, depth, and skin tone, since deeper skin needs conservative laser settings to protect pigment.

ONE REBERRY CLINIC · MFDS-REGISTERED DEVICES · MULTILINGUAL CARE AT EVERY LOCATION
The doctor grades your scars into the 3 main atrophic types (ice-pick, boxcar, rolling) plus any raised or pigmented marks.
Subcision passes a fine needle or cannula under rolling scars to cut the fibrous bands, releasing depressions in 1 or more sessions.
Fractional laser creates thousands of microscopic columns to remodel texture, usually over about 3 to 5 sessions 4 or more weeks apart.
Because scars coexist, subcision and laser are often combined so both depth and surface are addressed within 1 coordinated plan.
Your doctor reviews progress every few weeks and adjusts settings, since collagen remodelling continues for months after each session.

At our Gangnam (Seoul) location, Dr. Yoongon Ryu classifies your scar types and depth, then explains a realistic combined plan in English.
A session usually takes about 30 to 45 minutes including numbing, with fractional laser or subcision performed under local comfort measures.
Scar care runs as a course, typically 3 to 5 sessions spaced 4 or more weeks apart, so the plan is mapped across several months.
Improvement builds gradually as collagen remodels over weeks to months, and your doctor reviews progress to adjust settings.
Results generally hold well with sun protection and skincare, and occasional maintenance can further refine texture over the longer term.
Scar treatment in Gangnam is matched to the scar type: fractional laser resurfaces texture and boxcar scars, while subcision releases tethered rolling scars, and the two are often combined over a series of sessions. A doctor classifies your scars first. You can see the broader approach on our laser treatment page.
Most treatable scars are atrophic acne scars, grouped into ice-pick, boxcar, and rolling types, often linked to earlier acne treatment needs, plus texture and some pigmented marks. Each type differs in depth and shape, so a consultation classifies your scars before matching a method.
Neither is universally better; they solve different problems and are often combined. Fractional laser remodels surface texture and boxcar scars through microscopic healing columns, while subcision releases the fibrous bands that tether rolling scars from below. Your doctor selects and sequences them based on your scar type, which you can explore on our laser treatment page.
Comfort is managed with numbing measures. Fractional laser is performed after a numbing cream is applied, giving a warm, prickling sensation, while subcision uses local anaesthetic at the site so the release is well tolerated. Most patients describe the sessions as manageable, and your doctor explains what to expect before each step.
Downtime depends on the method. Fractional laser typically causes redness and a rough, sandpaper-like texture for a few days up to a week, while subcision can leave bruising and swelling for several days. Your doctor plans sessions around your schedule and gives aftercare so the skin recovers cleanly between visits.
Most fractional laser courses run about 3 to 5 sessions spaced 4 or more weeks apart, with subcision performed once or more alongside. The exact number depends on scar type, depth, and how your skin responds. Your doctor reviews progress between sessions and adjusts the plan, since collagen remodelling continues over months.
Scar treatment substantially improves and softens scars rather than erasing them entirely, since a scar is remodelled tissue, not fully normal skin. Combined resurfacing and release can achieve marked improvement over a course. Honest clinics set realistic expectations, and your doctor explains how much change is likely for your specific scar type and depth.
Visible improvement builds gradually over weeks to months as new collagen forms, not immediately after a single session. Subcision can lift a depression over several weeks, while fractional laser results accumulate across the course. Your doctor reviews progress at intervals so the plan and settings stay matched to how your scars respond.
Yes, when settings are chosen carefully, since deeper skin tones carry a higher risk of pigment changes with aggressive laser. Your doctor uses more conservative fractional settings and may favour subcision or non-ablative options to protect pigment. This tailoring is exactly why a doctor’s assessment precedes any scar treatment rather than a fixed protocol.
Yes, scar plans often combine subcision, fractional laser, and supportive care, and some patients add skin boosters or Rejuran Healer to aid recovery and skin quality. Your doctor sequences these so the skin is not over-stressed, coordinating each element within one plan rather than treating everything at once.
Most adults with atrophic acne scars or texture concerns whose active acne is controlled are suitable candidates. A consultation classifies your scars and checks skin readiness. If you have active breakouts, recent sun exposure, or a keloid history, your doctor will address these first and adapt the plan to keep treatment safe and effective.
Scar treatment is a well-established dermatological process and is generally considered safe when a trained doctor matches modality and settings to your scar type and skin tone. A consultation reduces risks such as pigment change or prolonged redness. You can review the approach on our laser treatment page first.
Aftercare centres on diligent sun protection, gentle non-irritating skincare, and letting any crust or redness heal without picking. This protects results and reduces pigment risk, especially after fractional laser. A supportive skin care routine helps recovery between sessions, and your doctor gives specific instructions tailored to the modalities used.
Our Gangnam (Seoul) location is in Seocho, about 2 minutes from Gangnam Station exit 10, where Dr. Yoongon Ryu provides scar care in English. International patients are also supported across our other Seoul-area locations, so you can pick the branch most convenient for your stay. Directions are confirmed when you book.
For a first session, 3 to 5 days is comfortable, allowing consultation, treatment, and initial recovery from any redness or bruising before you travel. Because scar plans run as a course, many international patients begin in Seoul and return for further sessions. Our English-speaking team helps coordinate timing around your trip.
Yes, flying within a day or two is generally fine after fractional laser or subcision, though you may still have redness, swelling, or bruising. Cabin air is drying, so moisturise and protect treated skin from sun. Your doctor advises on aftercare for travel and coordinates any follow-up sessions from abroad so the plan stays on track.
