Acne scar treatment is a set of collagen-remodelling procedures that improve the texture of skin left uneven after acne has healed. Most acne scars are atrophic, meaning depressed, and fall into ice-pick, boxcar, or rolling types. Because these scars sit at different depths, the plan usually combines controlled micro-injuries that stimulate the skin to lay down new collagen and smooth the surface over time.
The two mainstays are fractional laser, which creates microscopic columns of controlled thermal injury, and RF microneedling, which delivers radiofrequency energy into the dermis through fine needles. Both trigger a wound-healing response that firms and levels scar tissue across a course of visits, not a single appointment. Post-inflammatory marks and redness often improve alongside the texture.
At Reberry Clinic, scar care is consultation-led and delivered in English. For patients searching near Hongdae (Hongik Univ.) Station, treatment is provided across our Seoul locations in Gangnam and Myeongdong, both easily reached from 홍대입구역. The clinic’s doctors first assess your scar type and skin tone, then tailor the modalities and depth accordingly.
Fractional laser and RF microneedling both work by triggering the skin’s natural wound-healing cascade, but through different energy. Fractional laser vaporises or heats microscopic columns of tissue, leaving surrounding skin intact so healing is faster; the columns stimulate fresh collagen that lifts depressed scars. RF microneedling instead passes fine needles into the dermis and releases radiofrequency energy at a controlled depth, heating scar tissue below the surface while sparing the epidermis, which suits deeper skin tones prone to pigment change. For layered or mixed scarring, the clinic’s doctors may combine both across a series, since studies show combination protocols can outperform a single modality. Needle depth, energy level, and session spacing are matched to your scar type, skin colour, and how your skin responds, which is why acne scar treatment is planned as a course rather than delivered as one fixed session.

Doctors classify your scars across 3 main atrophic types (ice-pick, boxcar, rolling) and grade depth, which sets the modality and settings.
Fractional laser, RF microneedling, or both are selected; combination plans are used for mixed scarring, which studies link to greater improvement over 3 to 5 sessions.
Each session creates thousands of microscopic treatment zones or needle channels that trigger collagen remodelling below the scar.
Sessions are spaced about 4 to 6 weeks apart so the skin fully heals and new collagen matures between visits.
Your doctor reviews progress after each of the typical 3 to 5 sessions and adjusts depth or energy to keep improving texture safely.

The clinic’s doctors assess your scar type, depth, and skin tone, then explain which modalities suit you and how many of the typical 3 to 5 sessions you may need, in English.
After numbing, a session usually takes about 30 to 60 minutes depending on the area and whether modalities are combined.
Scar treatment runs as a course, with sessions spaced roughly 4 to 6 weeks apart to allow full healing between visits.
Texture improves gradually over weeks to months as collagen remodels, and your doctor reviews progress after each session.
Results are durable, but daily sunscreen and gentle skincare protect the remodelled skin; occasional touch-ups may help maintain smoothness.
Acne scar treatment uses collagen-remodelling procedures, mainly fractional laser and RF microneedling, to smooth atrophic scars over a series of sessions. It targets ice-pick, boxcar, and rolling scars at different depths. You can explore the wider approach on our acne treatment page before booking a consultation.
Patients searching near Hongdae (Hongik Univ.) Station are cared for at our Seoul locations in Gangnam and Myeongdong, both easily reached from 홍대입구역 by subway. A consultation there covers your scar assessment and plan, with full English support, so travelling a few stops from the Hongdae area is straightforward.
It depends on your scar type and skin tone rather than one option working best for everyone. Fractional laser suits boxcar and tone concerns, while RF microneedling works deeper and suits darker tones. Your doctor matches the modality at consultation, drawing on our laser treatment options.
Most atrophic scar plans run over about 3 to 5 sessions spaced roughly 4 to 6 weeks apart, since collagen remodels gradually between visits. The exact number depends on scar depth and how your skin responds. Your doctor reviews progress and adjusts the plan after each session.
Discomfort is managed with topical numbing cream applied before treatment, so most patients feel warmth, prickling, or pressure rather than sharp pain. RF microneedling adds a heat sensation at depth. Your doctor adjusts settings for comfort and explains what to expect for each modality beforehand.
Downtime is usually mild, with 1 to 3 days of redness and pinpoint marks for RF microneedling and a few days of flaking after fractional laser. Most people return to routines quickly. You can plan sessions around events, and your doctor explains recovery for your chosen modality.
Visible improvement builds gradually over several weeks to a few months as new collagen matures, not immediately after one session. Each of the typical 3 to 5 sessions adds to the effect. Your doctor tracks texture between visits so the plan stays matched to your response.
Improvements from collagen remodelling are generally long-lasting once a course is complete, though acne scars are not fully erased and results build over time. Daily sun protection helps preserve them. Occasional maintenance sessions may be suggested, which your doctor discusses at consultation based on your skin.
Yes, fractional laser and RF microneedling are often combined for mixed or layered scarring, and studies link combination protocols to greater improvement than one modality alone. A combined plan may also include supportive care. Your doctor sequences them safely so the skin is not over-stressed between sessions.
Yes, with the right modality and conservative settings; RF microneedling is often preferred for deeper tones because it works below the surface while sparing the epidermis, reducing pigment risk. Your doctor assesses your skin tone at consultation and adjusts energy accordingly to keep treatment both safe and effective.
Atrophic scars form when inflammatory acne damages collagen and the skin heals with a loss of tissue, leaving depressions such as ice-pick, boxcar, or rolling scars. Controlling active acne first helps prevent new scars. A tailored skin care routine supports healthy healing between sessions.
Yes, controlling active inflammatory acne first is important, since treating scars while acne is flaring can be less effective and irritate the skin. Your doctor may address active lesions on our acne treatment track first, then move to scar remodelling once your skin is calmer.
Daily broad-spectrum sunscreen, gentle non-irritating cleansing, and avoiding picking are essential to protect the remodelling skin. Moisturise well while any flaking settles. A supportive skin care routine helps maintain results between sessions, and your doctor gives specific guidance for each modality.
Yes, post-inflammatory redness and marks often improve alongside texture, since the same collagen-remodelling process supports overall skin recovery. Fractional laser in particular can help even tone. Persistent pigment may need extra care, which your doctor plans at consultation as part of a complete approach.
Most adults with atrophic acne scars and controlled active acne are suitable candidates for a structured series. A consultation grades your scar type, depth, and skin tone to confirm which modalities fit. Those with keloid tendencies or recent isotretinoin use need careful assessment first, which your doctor explains upfront.
For a first session, 2 to 3 days is comfortable, allowing a consultation, the procedure, and a short review. Because scar plans run as a course over weeks, many international patients begin in Seoul and continue across return visits. Our English-speaking team helps schedule around your travel from the Hongdae area.
Yes, flying within a day or so is generally fine, as these are non-invasive to minimally invasive procedures. Cabin air is drying, so moisturise and protect treated skin from sun. If you had fractional laser or RF microneedling, your doctor advises on aftercare while you travel.
International patients can complete a scar course across one or more visits, and the clinic offers remote check-ins in English between trips to keep the plan on track. You can continue supportive skin care at home. Your treatment notes are kept on file for continuity across sessions.
