Subcision is a needle release: a physician passes a beveled Nokor needle under a depressed scar and severs the fibrous bands anchoring it to the tissue below. Freed of that tether, the surface springs up, and the small pocket left behind fills with new collagen over the following weeks. It works best on rolling and tethered scars, is often paired with RF microneedling or a PDLLA base for stubborn cases, and at RE:BERRY Gangnam the physician who runs the stretch test performs the release and reads the review.
Effects & Progress
Effects & Progress
The physician stretch-tests each scar first and matches the tool to what it is, the needle for tethered rolling scars and laser for pits, so one device is never run blindly across every mark.
Some elevation is often visible on the table as the tether gives way. Firmness and swelling over the treated zone settle that evening; bruising begins to show the next day.
Bruising peaks around days two to four and fades through the first week. Most guests are back to social plans within seven days; makeup covers the last of it.
New collagen begins filling the released pocket from below over the following weeks. The next session in a three-to-four-visit plan is usually placed at four to six weeks.
The main correction phase. The freed depression continues to rise as remodeling completes across two to six months, and response depth varies with scar age and skin.

Effects & Progress
Acne scarring is rarely one kind of scar. A single cheek can carry rolling depressions held down by fibrous cords, shallow boxcar edges, and narrow icepick pits, and they do not answer to the same tool. The physician stretch-tests each one first, marks the tethered scars that shallow under tension for the Nokor needle, and routes the pits with no cord to cut toward fractional laser, so the device is matched to the scar in front of it, not chosen before the skin is even read.
Cutting the tether lets a scar rise, but a scar bed that is also collagen-poor can collapse back onto the same plane. That is the second problem a combined plan handles. The pocket left after release recruits fibroblasts to lay down fresh collagen, and adding RF microneedling heats the dermis to rebuild that floor, while a PDLLA microsphere base can be laid into the freed space to hold the plane open. Whether a scar needs one step or two is decided at the stretch test, and the release, the resurfacing, and the collagen support are staged in the order the scar actually needs.
A scarred cheek is seldom just dents. Enlarged pores, uneven texture, and post-acne redness usually sit alongside the depressions, and treating only the tethered scars leaves the rest of the picture untouched. So the plan is read as a whole: subcision lifts the rolling scars, RF microneedling or laser resurfaces the texture and tightens pores, and calming aftercare settles the redness that scar-prone skin tends to flare. Each step is sequenced so one does not aggravate another, and the mix is set to your skin, never sold as a fixed bundle.
Scar work is measured, not eyeballed. The physician counts and photographs every tethered scar under standardized clinic lighting at the outset, and the release plan, how many scars and how many sessions, is confirmed in writing before anything begins, with the figure quoted after the stretch test, once your scars have been seen. At each 90-day checkpoint the same overlay photos are compared side by side, so the change is shown in a way a bathroom mirror tends to hide, and the same physician who felt the cords release reads whether each depression has actually risen.

What Subcision Changes Under the Skin โ and How the Lift Builds
- It treats the anchor, not the surface: a rolling scar looks like a dent, but the problem is the cord underneath, and cutting that cord is what lets the dent rise
- The pocket left after release recruits fibroblasts, so your own tissue rebuilds the depression from below over roughly two to six months
- Paired with RF microneedling when a scar bed also needs collagen at the dermis, the two act on different problems: one releases the tether, the other resurfaces
- A PDLLA microsphere base can be laid into the freed pocket to hold the plane open, which cuts the re-tethering that subcision alone sometimes leaves behind
- Icepick pits are honestly triaged out to laser, because a narrow deep pit has no fibrous band for the needle to release
- One physician runs the stretch test, performs every pass, and reads your overlay photos at each checkpoint, so the case is never handed off between stages

Subcision vs RF Microneedling vs Fractional Laser โ Matching the Tool to the Scar
| Criteria | Subcision (RE:BERRY Gangnam) | RF Microneedling | Fractional Laser |
|---|---|---|---|
| What it acts on | Fibrous cords tethering the scar down | Dermal collagen via heated micro-needles | Epidermal and upper-dermal columns of tissue |
| Best-suited scar | Rolling and tethered depressed scars | Broad shallow acne scarring and texture | Icepick pits, fine texture, tone |
| Mechanism | Mechanical release, then collagen fills the pocket | Thermal stimulus rebuilds dermal collagen | Controlled micro-injury drives resurfacing |
| Reaches the tether? | Yes โ that is its whole job | No โ it heats, it does not cut cords | No โ it works at and near the surface |
| Sessions | Typically 3-4, spaced 4-6 weeks | Usually a short series | Usually a short series |
| Downtime | Bruising for a few days, social life within a week | Redness 1-2 days, pinpoint marks | Redness and flaking for several days |
| Often combined? | Frequently paired with RF microneedling | Frequently paired with subcision | Added for pits subcision cannot reach |
| Correction builds | Rises over 2-6 months per session | Over weeks as collagen remodels | Over weeks with repeated passes |
Why This Matters
These three do genuinely different work, so at RE:BERRY Gangnam they are chosen by scar type, not sold as a package. Subcision is the only one that reaches the fibrous band holding a rolling scar down; RF microneedling rebuilds collagen but leaves the cord intact; fractional laser resurfaces but cannot release a tether. A face with mixed scarring often needs the release first and resurfacing second, so the physician stretch-tests before naming any device. The โฉ19,000 (about $14) figure covers the release plan set at that consultation.
Subcision alone can under-deliver on a deep scar bed if the pocket collapses back onto the same plane. Pairing it with RF microneedling, or laying a PDLLA base into the freed space, addresses that second problem directly: one step frees the scar, the other keeps the plane open and lays down collagen. Whether a scar needs one step or two is a call the physician makes from the stretch test, and the written โฉ19,000 (about $14) reflects the plan you actually get.
KHIDI's 2025 international patient survey found 41.4% of respondents rank keeping the same doctor throughout as their leading criterion. Scar work rewards that continuity: the physician who felt which cords released under the needle is the one reading whether the depression has risen at your 30- and 60-day overlay photos.

The Evidence Behind Subcision and Its Combined Protocols
Subcision has a plain mechanical logic and a longer regenerative one. The needle severs the fibrous septae that pull a rolling scar toward the deeper tissue; the bleeding that follows organizes into a small pocket, and that pocket becomes the scaffold where fibroblasts lay down fresh collagen. The mechanical release is what you see on the table. The collagen fill is what keeps the correction over the following months, and it is the same wound-repair biology that drives most regenerative aesthetic work.
When subcision is combined with an energy device, the added evidence is about the second layer of the problem. Radiofrequency delivered into the dermis converts tissue resistance into controlled heat, which partially denatures existing collagen and then drives new collagen expression during repair; histology of RF-treated skin documented exactly this two-phase response. That is why a scar bed that is not only tethered but also thin and collagen-poor is often released first and then treated with RF microneedling: the needle handles the cord, the heat rebuilds the floor.

Two further points matter for Asian skin, which is the skin most RE:BERRY guests bring. First, radiofrequency energy is chromophore-independent, heating by tissue resistance rather than by targeting melanin, and a Japanese non-ablative RF series recorded sustained improvement with no pigmentary change, a real consideration when treating scar-prone darker phototypes. Second, the multiple-pass, moderate-energy RF approach validated in a large physician survey is the same restrained technique used when RF microneedling backs up a subcision plan, chosen for comfort and for a lower risk of post-inflammatory marks.

None of this replaces the stretch test. The literature explains why a released, collagen-supported scar improves; it does not tell you which scar on your cheek is tethered and which is a narrow pit with no cord to cut. That call is made by the physician's hands under clinic lighting, and it is the reason icepick scars are routed to laser once the release has done its job on the tethered ones.
Questions International Guests Ask About Subcision in Korea
What exactly does subcision do to an acne scar?
A depressed rolling scar is held below the surface by fibrous bands that tie it to the deeper tissue. During subcision the physician passes a beveled Nokor needle under the scar and cuts those bands. Once the tether is gone the surface can lift, and the small pocket left behind fills with new collagen over the following weeks. It is a release, not a resurfacing.
Which acne scars respond to subcision and which do not?
Rolling scars and other tethered depressions are the ones subcision was designed for, because they have a fibrous cord to cut. Boxcar scars can respond partially. Icepick scars โ narrow, deep pits โ usually have no band to release, so at RE:BERRY Gangnam those are routed to fractional laser instead. The physician stretch-tests each scar in person before deciding.
How is a subcision session actually run at your clinic?
The physician maps every tethered scar under clinic lighting, numbs the area, then enters through a single point and fans the Nokor needle beneath each marked scar to sever the cords. Cold LDM soothing and light compression follow to hold bruising down. The needle work itself takes only a few minutes per zone; most of the appointment is mapping and aftercare.
Why is subcision often combined with RF microneedling?
The two solve different problems. Subcision releases the cord that holds a scar down; RF microneedling delivers heat into the dermis to rebuild collagen in a thin, damaged scar bed. When a scar is both tethered and collagen-poor, releasing it and then resurfacing the floor gives a fuller result than either step alone. Whether you need one or both is decided at the stretch test.
What is the point of adding a PDLLA base after subcision?
Subcision alone sometimes lets the freed scar re-tether onto the same plane as the pocket collapses. Laying a PDLLA microsphere base into that freed space helps hold the plane open and stimulates collagen while it does so. It is reserved for deeper scars prone to relapse, not used routinely, and the physician will tell you plainly whether your scar needs it.
Does subcision hurt?
The area is numbed with local anaesthetic before any needle pass, so most guests describe pressure and tugging during the release, not sharp pain. There is a dull ache and firmness afterward as the treated tissue settles. The physician adjusts anaesthetic and pace to your feedback, and the actual needle work in each zone is brief.
How much bruising should I expect, and how long does it last?
Bruising is the main visible after-effect because the release involves controlled bleeding under the skin, and that pocket is part of how the correction forms. It typically deepens around days two to four and fades through the first week. Cold LDM and light compression on the day help keep it down, and most guests are comfortable in social settings within seven days.
How many subcision sessions will I need?
Most scar plans run three to four sessions spaced four to six weeks apart. Each release lets the depression rise further and each collagen cycle adds to the last, so scarring built over years is corrected in stages across several visits. Your exact count depends on how many scars are tethered and how deep the cords sit, confirmed after mapping.
When will I see the scars actually improve?
There are two moments. Some elevation is often visible on the table as the tether gives way. The larger, lasting change builds over roughly two to six months as new collagen fills the freed pocket, and it continues session to session. Overlay photos at each 90-day checkpoint tend to show the change more honestly than a bathroom mirror does.
Can I fly home soon after subcision?
Yes. There is no open wound and no recovery room, so flying is fine within a day or two; the main consideration is that visible bruising may still be present. Many guests plan the session for early in a Seoul trip so the bruising is settling by the time they head home, and a next visit is scheduled four to six weeks out.
Does my skin tone affect whether subcision is safe for me?
Subcision is a mechanical release, not a light- or heat-based treatment, so it does not target melanin and is used across skin phototypes. Darker, scar-prone skin still needs a careful hand to limit post-inflammatory marks, which is one reason RE:BERRY Gangnam favours a restrained technique and photographs your skin under standardized lighting at every checkpoint.
How does the cost of scar work in Korea compare with home?
Seoul remains a major reason scar patients travel, and RE:BERRY Gangnam confirms the figure for your release plan in writing at the free consultation before anything is scheduled, and the written total is what you pay, with no add-ons layered on afterward. Whether the plan is subcision alone or a combined protocol changes that figure, so it is quoted after the stretch test once the physician has seen your scars, not promised sight-unseen online.
Will the same doctor do my whole scar plan?
Yes. The physician who runs your stretch test performs every needle pass and reads your overlay photos at each checkpoint. Scar work depends on that continuity โ knowing which cords released under the needle last time is what guides the next session โ so at RE:BERRY Gangnam a case is not handed between practitioners between visits.

Science Subcision and RF-supported scar remodeling โ peer-reviewed references
The regenerative case for releasing and then rebuilding a scar rests on established wound-repair and radiofrequency evidence. Hantash (2009) showed that fractional radiofrequency drives both neoelastogenesis and neocollagenesis in treated skin, the collagen-and-elastin response a released scar bed depends on. Fitzpatrick (2003) measured objective tissue tightening after non-ablative RF in a multicenter trial, and Kushikata (2005) confirmed sustained improvement in Asian skin with no pigmentary change, which matters because RF heats by tissue resistance rather than by targeting melanin. Dover (2007), across 5,700 facial treatments, validated the multiple-pass, moderate-energy technique used when RF microneedling backs up a subcision plan for comfort and a lower risk of post-inflammatory marks.
