Atrophic acne scars come in 3 main shapes (ice-pick, boxcar, rolling), so most plans layer fractional resurfacing over a series of sessions rather than one visit.
Acne scar treatment near Incheon Airport in Korea resurfaces atrophic scars using fractional laser and RF microneedling, which stimulate new collagen in the dermis over a planned series of sessions. At our Incheon Airport (Yeongjongdo) location, Dr. Sunbeen Kim assesses your scar type first, since ice-pick, boxcar, and rolling scars respond to different settings.

Acne scar treatment is a resurfacing approach that rebuilds skin texture where healed acne has left permanent depressions. Unlike active acne, which involves oil and inflammation, atrophic scars are a structural problem: collagen was lost during healing, leaving ice-pick, boxcar, or rolling depressions. Treatment works by controlled micro-injury that triggers new collagen, gradually lifting and smoothing the scar floor over months.
The two mainstays are fractional lasers, which vaporise microscopic columns of tissue to prompt remodelling, and RF microneedling, which delivers radiofrequency energy through fine needles into the dermis. Because scar depth and shape vary, most patients complete a series of sessions spaced several weeks apart rather than expecting one dramatic visit.
At Reberry Clinic’s Incheon Airport (Yeongjongdo) location, near ICN, Dr. Sunbeen Kim, our Medical Director there, first grades your scars and skin type, then matches the modality and number of sessions to your case. English-language support makes this practical for transit and stopover patients passing through Incheon Airport, Korea.
Atrophic acne scars improve when the dermis is prompted to lay down new collagen beneath the depressed scar floor, and two device families do this. Fractional ablative lasers, such as fractional CO2, create microscopic thermal columns that vaporise damaged tissue in a pixelated pattern, leaving surrounding skin intact so healing is faster than fully ablative resurfacing. RF microneedling instead drives insulated fine needles into the dermis and releases radiofrequency energy at depth, remodelling collagen while largely sparing the surface epidermis, which suits deeper skin tones. Rolling and shallow boxcar scars often respond well to fractional resurfacing, while narrow ice-pick scars may need targeted techniques layered in. Because each device works by injury-then-repair, results build across a series rather than one session, and the doctor sets energy and needle depth to your scar shape and skin type. This device selection is why your plan and its cost are confirmed only after assessment, not from a fixed menu.

The doctor classifies your scars across the 3 atrophic types and grades severity, since each type responds to different settings.
Fractional laser or RF microneedling is selected, and 2 modalities are sometimes combined for mixed scarring in one plan.
Fine channels or micro-columns reach the dermis at a set depth, triggering a wound-healing response that lays down new collagen over 4 to 12 weeks.
Most scar plans run 3 to 5 sessions spaced about 4 weeks apart, because collagen remodelling is gradual, not immediate.
Between sessions the doctor reviews progress and adjusts depth or energy so improvement continues safely across the series.

At our Incheon Airport (Yeongjongdo) location, Dr. Sunbeen Kim grades your scar types and skin, then explains which modality and how many sessions fit your case, in English.
After numbing, a resurfacing session usually takes about 20 to 40 minutes depending on the area and modality used.
Scar plans run as a course of about 3 to 5 sessions spaced roughly 4 weeks apart, so the schedule is mapped in advance.
Collagen remodelling is gradual, so texture keeps improving for several weeks to months after each session as the series progresses.
Improvements from remodelled collagen are durable, though diligent sun protection and occasional maintenance help preserve the smoother texture.
Acne scar treatment resurfaces the skin to improve permanent atrophic scars, using fractional laser or RF microneedling to rebuild collagen. It differs from treating active acne, which targets oil and inflammation. Scars are structural, so they need resurfacing rather than anti-acne care alone. Learn more on our acne treatment page.
The 3 atrophic scar types, ice-pick, boxcar, and rolling, can all be improved, though each responds differently. Rolling and shallow boxcar scars often suit fractional resurfacing, while narrow ice-pick scars may need targeted techniques layered in. A consultation grades your scars first so the plan matches their shape and depth.
Discomfort is managed with topical numbing before the procedure, so most patients tolerate it well. You may feel warmth during laser passes or pressure during RF microneedling. Sensation lasts only through the short session, and your doctor adjusts settings for comfort. Explore related options on our laser treatment page.
Downtime is usually a few days of redness, mild swelling, and flaking, depending on the modality and intensity. Fractional CO2 laser can mean a slightly longer surface recovery than RF microneedling. Most patients resume normal routines quickly with sun protection. Your doctor explains expected recovery before each session so you can plan travel.
Because treatment works by stimulating new collagen, texture improves gradually over several weeks to months, not immediately after one session. Most plans build visible change across a series of 3 to 5 sessions. Your doctor reviews progress between visits so the plan stays matched to how your scars respond.
Most scar plans run about 3 to 5 sessions spaced roughly 4 weeks apart, because collagen remodelling is gradual. Deeper or mixed scarring may need more, while shallow scars may need fewer. Your exact number is set at consultation based on scar type, depth, and how your skin responds over the course.
Improvements come from newly built collagen, so the smoother texture is durable rather than temporary. Scars are softened and lifted, not fully erased, and aging or new breakouts can still affect skin over time. Diligent sun protection and occasional maintenance help preserve results well after the series ends.
Yes, plans often layer fractional laser and RF microneedling for mixed scar types, and supportive skin boosters can improve overall skin quality alongside resurfacing. A booster such as Rejuran Healer may complement scar work. Your doctor sequences treatments so the skin is not over-stressed.
Safety depends on matching modality and settings to your skin type. Deeper skin tones often suit RF microneedling, which spares the surface and lowers pigment risk, over aggressive ablative laser. Your doctor assesses your skin type first and selects conservative settings where needed to reduce the chance of pigment changes.
Generally yes, resurfacing works best once active breakouts are controlled, since treating over inflamed acne can irritate skin. If you still have active acne, your doctor may stabilise it first, then move to scar work. You can review active-acne options on our acne treatment page.
Temporary redness, swelling, flaking, and sensitivity are the most common effects and settle within days. Less common are transient pigment changes, especially without sun protection. Serious effects are uncommon when a doctor sets appropriate depth and energy for your skin. A consultation reduces these risks by tailoring settings to you.
Daily broad-spectrum sunscreen, gentle non-irritating skincare, and avoiding picking or scrubbing are essential while skin heals. Keeping the barrier hydrated supports remodelling between sessions. A supportive skin care routine helps protect results, and your doctor gives specific instructions after each resurfacing session.
Cost depends on your scar type and depth, the modality chosen, and how many sessions your plan needs, so it is set after assessment rather than from a fixed menu. Deep or mixed scarring usually needs more sessions than shallow scars. Your doctor explains an individualised, transparent cost at consultation.

Yes, flying within a day or so is generally fine after most resurfacing sessions, which are minimally invasive. Cabin air is drying, so moisturise and protect treated skin from sun. After fractional CO2 laser you may still be flaking, so your doctor advises on aftercare while you travel.
International patients can complete a scar course across return visits, and the clinic offers remote check-ins in English between trips so the plan stays on track. You can also continue supportive skin care at home. Your treatment notes are kept on file for continuity across sessions.
Rarely, since scar remodelling is gradual and cumulative, so a single session gives limited change compared with a planned series. Very shallow scarring might improve noticeably after one visit, but most atrophic scars need several. Your doctor sets a realistic session count at consultation based on your scar grade.
