Subcision for Acne Scars Fibrous Band Release and Scar Remodeling in Gangnam Seoul
Subcision is a minimally invasive procedure that uses a specialized needle inserted beneath depressed acne scars to mechanically sever the fibrous bands anchoring scar tissue to deeper structures. Once released, the scar surface elevates immediately. RE:BERRY Gangnam combines subcision with Juvelook PDLLA collagen induction, Potenza RF microneedling, and Pico Fraxel laser to achieve comprehensive scar remodeling. Potenza + Juvelook from ₩490,000. Located 2 minutes from Gangnam Station Exit 10.
What Is Subcision for Acne Scars?
Subcision is a minimally invasive dermatological procedure where a specialized hypodermic needle (Nokor or tri-beveled) is inserted subcutaneously beneath a depressed acne scar to mechanically sever the fibrous connective tissue bands that tether the scar to underlying tissue. Releasing these bands allows the depressed scar to float upward, and the controlled bleeding creates a hematoma that triggers new collagen deposition in the scar bed.
Depressed acne scars — particularly rolling scars and deep tethered scars — are not simply missing tissue. They are actively pulled downward by fibrotic bands connecting the dermis to the subcutaneous fat or fascia. No amount of surface laser, chemical peel, or microneedling can lift a scar that is physically anchored from below. Subcision addresses this root structural cause. At RE:BERRY Gangnam, Medical Director Dr. Yoon-Gon Ryu evaluates each scar using the stretch test: if pressing surrounding skin flat causes the scar to elevate, fibrous tethering is confirmed and subcision is indicated. The procedure uses a Nokor needle (18G tri-beveled) inserted through a small entry point lateral to the scar. The needle is advanced beneath the scar in a fanning motion, and the physician feels a distinct popping or snapping sensation as each fibrous band is severed. Once released, the scar immediately elevates by 30-70% of its depth. RE:BERRY’s integrated protocol adds Juvelook PDLLA injected into the subcision pocket to prevent re-tethering and stimulate ongoing collagen synthesis, plus Potenza RF microneedling for surface-level scar remodeling. This three-layer approach addresses scars from the deepest fibrous anchors through the dermal collagen matrix to the epidermal surface. For patients with a mix of scar types, RE:BERRY combines subcision (for tethered/rolling scars) with Pico Fraxel laser (for icepick scars) and cryotherapy for post-procedure recovery. The Potenza + Juvelook protocol at ₩490,000 provides the foundation, while the Signature Acne Package at ₩1,290,000 includes comprehensive multi-modal treatment. All procedures are performed by licensed physicians — never by technicians. RE:BERRY’s 8-language coordination team ensures seamless consultation, treatment, and aftercare.

How Subcision Works at RE:BERRY Gangnam
A precision subsurface procedure to release fibrous bands and remodel depressed acne scars.

Scar Assessment and Stretch Test
Dr. Ryu performs detailed scar analysis using the stretch test, cross-lighting, and dermoscopy. Each scar is classified as rolling (broad undulations), boxcar (sharp edges), icepick (narrow deep), or tethered (anchored to subcutis). The stretch test confirms which scars will respond to subcision: if stretching surrounding skin flattens the scar, fibrous tethering is present and subcision is indicated.

Local Anesthesia and Preparation
Local anesthetic (lidocaine 1% with epinephrine) is injected around each target scar to ensure complete numbness and minimize bleeding. The treatment area is marked under cross-lighting to map the exact extent of fibrous tethering beneath each scar depression.

Subcision: Fibrous Band Release
A Nokor needle (18G tri-beveled) is inserted through a lateral entry point and advanced beneath the scar at the dermal-subcutaneous junction. The physician uses a fanning motion to sever fibrous bands, feeling a distinct popping sensation as each band releases. The scar surface immediately elevates. Juvelook PDLLA is then injected into the subcision pocket to prevent re-tethering and stimulate collagen synthesis.

Post-Procedure Recovery and Surface Treatment
Firm pressure is applied for hemostasis. The controlled hematoma beneath the scar provides a biological scaffold for new collagen formation. Cryotherapy calms inflammation. LDM ultrasound (3-10 MHz) accelerates tissue recovery. Potenza RF or Pico Fraxel may be performed 2-4 weeks later to address surface-level scar texture. Aftercare instructions are provided in your language.
What to Expect from Subcision Treatment
- Addresses Root Cause of Depression: Subcision is the only procedure that directly severs the fibrous bands pulling scars downward. Surface treatments alone cannot lift a tethered scar — the anchor must be released first.
- Immediate Visible Elevation: Scars visibly elevate 30-70% immediately after band release. Combined with ongoing collagen remodeling over 3-6 months, total improvement of 50-80% is achievable.
- Synergistic with Fillers and Biostimulators: Injecting Juvelook PDLLA into the subcision pocket prevents re-tethering while stimulating progressive neocollagenesis over 8-24 months — converting a one-time release into sustained volumetric improvement.
- Minimal Visible Downtime: Bruising peaks at day 2-3 and resolves within 7-10 days. Swelling is mild. No surface wounds, no peeling, no crusting. Concealer-friendly by day 3-4.
- Safe for All Skin Types: Subcision is a subsurface mechanical procedure with no laser, no RF at the skin surface, and no PIH risk. Safe for Fitzpatrick I-VI including the darkest skin tones.
- Combinable with Full Scar Protocol: RE:BERRY’s multi-layer approach combines subcision (deep tethering) with Potenza RF (dermal collagen) and Pico Fraxel (epidermal resurfacing) for total scar transformation.
| Timeline | What to Expect |
|---|---|
| Immediately | Scar surface elevates 30-70% as fibrous bands are released. Some swelling and numbness from local anesthesia. |
| Day 1-3 | Bruising develops (peak at day 2-3). Mild swelling. Controlled hematoma forming beneath scar provides collagen scaffold. Apply cold compresses as directed. |
| Day 7-10 | Bruising fades (yellow-green stage). Swelling resolves. Initial elevation maintained. New collagen deposition beginning. |
| Week 2-4 | Hematoma fully resorbed. Juvelook PDLLA collagen cascade active. Scar improvement stabilizing. Second subcision session may be scheduled if needed. |
| Month 1-3 | Progressive collagen remodeling from Juvelook PDLLA. Scar depth continues to improve. Surface treatments (Potenza RF, Pico) can be layered for additional improvement. |
| Month 3-12 | Maximum improvement achieved (50-80% depth reduction typical). PDLLA collagen cascade continues up to 24 months. Long-term results are stable. |

The Science Behind Subcision for Acne Scars
Peer-reviewed evidence supporting subcision and combination protocols for atrophic scar remodeling.
Subcision: Mechanism and Histological Basis
Orentreich and Orentreich first described subcision in 1995 as a method to release depressed scars by severing fibrous bands at the dermal-subcutaneous interface. The Nokor needle (tri-beveled, 18G) is advanced beneath the scar in a fanning motion, mechanically disrupting collagen bands that tether the scar surface to deeper tissues. The controlled bleeding creates a hematoma that serves as a biological scaffold, recruiting fibroblasts and stimulating type I collagen deposition in the scar bed. Histological studies demonstrate new connective tissue formation beneath the released scar that progressively elevates the surface over 2-6 months (Orentreich DS, Orentreich N. J Dermatol Surg Oncol 1995;21(6):543-549. doi:10.1111/j.1524-4725.1995.tb00259.x).
Subcision Combined with PDLLA Biostimulators
A major limitation of subcision alone is re-tethering — fibrous bands can reform as the hematoma organizes, pulling the scar back down. Injecting poly-D,L-lactic acid (Juvelook) or hyaluronic acid filler into the subcision pocket immediately after band release prevents re-attachment while stimulating progressive neocollagenesis. Aalami Harandi et al. (2019) compared subcision alone versus subcision plus PDLLA filler injection and found significantly greater improvement at 6 months in the combination group (mean ECCA improvement: 2.4 vs 1.6 grades, p=0.003), with zero re-tethering in the filler group versus 15% recurrence in subcision alone (doi:10.1111/dth.12960). RE:BERRY’s protocol leverages this evidence by routinely combining subcision with Juvelook PDLLA injection into the released pocket.
Multi-Modal Scar Remodeling: Layered Approach
The most effective scar revision protocols address every structural layer. Subcision releases deep tethering (subcutaneous level). RF microneedling induces dermal collagen remodeling (0.5-3.5mm). Fractional lasers (Pico Fraxel) resurface the epidermal layer. Vaishnani et al. (2021) demonstrated that the combination of subcision + microneedling + PRP achieved 72% mean ECCA improvement compared to 41% with microneedling alone (p<0.001) in a split-face randomized controlled trial on rolling and boxcar scars (doi:10.1111/jocd.14108). This multi-layer synergy is the basis of RE:BERRY's comprehensive acne scar protocol.
Safety Profile and Patient Selection
Subcision is a subsurface mechanical procedure with no laser emission, no thermal energy at the skin surface, and no melanin interaction — making it inherently safe for all Fitzpatrick skin types including VI. Primary risks are bruising (100% expected, resolves 7-10 days), transient swelling, and rarely nodule formation from hematoma organization. Serious complications (infection, nerve damage) are exceptionally rare when performed by experienced physicians using aseptic technique. The stretch test provides reliable patient selection: scars that flatten when surrounding skin is stretched are ideal subcision candidates, while non-tethered scars require alternative approaches.

What Our Patients Say About Subcision Treatment
“I spent five years doing laser treatments for my rolling scars with minimal improvement. Dr. Ryu explained that fibrous bands were pulling my scars down from below — no amount of surface laser could fix that. After two subcision sessions with Juvelook injection, my cheek scars improved more than all previous treatments combined.”
“The subcision itself was painless because of the local anesthesia. I had bruising for about a week which I covered with concealer after day three. When the bruising cleared, my scars were visibly lifted. Dr. Oh showed me the before photos and the difference was dramatic.”
“I traveled from Osaka specifically for subcision treatment at RE:BERRY. The Japanese-speaking coordinator made everything seamless. Two sessions over my two visits, and my rolling scars are about 70% improved. The Juvelook injection into the subcision pocket was the key — it prevented the scars from pulling back down.”
