Subcision Acne Scar Treatment in Gangnam Seoul
Deep rolling and tethered acne scars resist laser and topical treatments because fibrous bands physically anchor the skin downward. RE:BERRY Gangnam performs physician-only subcision to mechanically release these tethers, combined with Juvelook PDLLA or filler injection to prevent re-tethering and restore dermal volume — achieving 40-70% scar depth improvement from ₩490,000, just two minutes from Gangnam Station Exit 10.
What Is Subcision for Acne Scars at RE:BERRY Gangnam?
Subcision at RE:BERRY Gangnam is a physician-performed procedure using a Nokor needle to sever fibrous tethers beneath rolling and bound-down acne scars, followed by Juvelook PDLLA injection to prevent re-attachment and stimulate collagen regeneration — achieving 40-70% scar depth improvement from ₩490,000 per session.
At RE:BERRY Gangnam, Medical Director Dr. Yoon-Gon Ryu performs subcision for acne scars using the precision Nokor needle technique, which has remained the gold standard for tethered scar release since its introduction by Orentreich and Orentreich in 1995. Unlike laser-only approaches that address surface texture without correcting the structural cause, subcision physically disrupts the fibrotic strands that pull scar tissue downward, allowing the skin to elevate naturally. The procedure is combined with Juvelook PDLLA filler or hyaluronic acid injection into the subcised space to prevent re-tethering and provide sustained collagen scaffolding. For comprehensive acne scar revision, Dr. Ryu often incorporates subcision into multi-modal protocols alongside Potenza RF microneedling and Pico Fraxel laser for patients with mixed scar morphologies (rolling, boxcar, and icepick). All subcision procedures are physician-performed at RE:BERRY Gangnam — never delegated to nurses or technicians. Our 8-language coordination team supports international patients throughout the scar revision journey.

How Subcision for Acne Scars Works at RE:BERRY Gangnam
A physician-performed multi-step subcision protocol targeting the structural cause of tethered and rolling acne scars.
Scar Assessment & Morphology Mapping
Dr. Yoon-Gon Ryu examines each acne scar under high-magnification dermoscopy and cross-polarized lighting to classify scar type (rolling, boxcar, icepick, or mixed), depth, and degree of tethering. The lateral stretch test identifies which scars are tethered — if a scar flattens when the surrounding skin is stretched, subcision is indicated. A detailed scar map is created to guide the subcision procedure, documenting the exact location, size, and depth of each target scar. This consultation takes 15-20 minutes and is included in every subcision acne scar treatment at RE:BERRY Gangnam.
Local Anesthesia & Preparation
Targeted local anesthesia (lidocaine with epinephrine) is injected beneath each scar cluster to ensure complete numbness during subcision. The epinephrine component provides vasoconstriction to minimize bruising. The injection itself serves a dual purpose — the fluid volume creates hydraulic dissection that partially loosens the fibrous tethers before the needle even enters. Total preparation time is 10-15 minutes. The treatment area is then marked with a surgical marker to guide the subcision pattern.
Nokor Needle Subcision
Dr. Ryu inserts the specialized Nokor needle (18-gauge tribeveled) parallel to the skin surface at 3-5mm depth beneath each tethered acne scar. Using controlled fanning motions, the needle severs the fibrotic bands that anchor the scar to deeper tissue. An audible or tactile pop confirms successful release of each tether. The procedure is methodical and precise — each scar requires 15-30 seconds of targeted subcision. For a full-face session treating 10-20 tethered scars, the subcision phase takes approximately 20-30 minutes. Blood pooling beneath the released scars creates a natural space-filling hematoma that supports skin elevation.
Juvelook Injection & Recovery Protocol
Immediately after subcision, Juvelook PDLLA (₩340,000 for 4cc) or hyaluronic acid filler is injected into the subcised space beneath each scar. This serves three critical purposes: (1) prevents re-tethering by occupying the released space, (2) provides immediate volumetric elevation of depressed scars, and (3) stimulates sustained neocollagenesis over 8-24 months as PDLLA microspheres degrade. LDM ultrasound is applied afterward to reduce swelling and accelerate healing. Total session time including preparation is 60-90 minutes. A compression dressing may be applied overnight for 24 hours.
What to Expect from Subcision Acne Scar Treatment
- Targets the Root Cause Subcision is the only procedure that physically severs the fibrous tethers causing rolling and bound-down acne scars. Lasers and chemical peels treat the surface; subcision treats the structural anchor pulling skin downward.
- Immediate Scar Elevation 40-50% of visible scar improvement occurs immediately after subcision as the released skin springs upward. The sub-dermal hematoma and injected filler maintain this elevation during the healing phase.
- Progressive Collagen Remodeling Juvelook PDLLA microspheres injected into the subcised space stimulate continuous neocollagenesis over 8-24 months, adding structural collagen that permanently replaces the severed scar tissue.
- Safe for All Skin Types Unlike ablative lasers, subcision carries minimal risk of post-inflammatory hyperpigmentation (PIH) in darker skin types (Fitzpatrick IV-VI). The procedure works beneath the epidermis, leaving the melanocyte-containing skin surface intact.
- Combinable with Other Treatments Subcision synergizes with Potenza RF microneedling, Pico Fraxel, and skin boosters for mixed scar types. At RE:BERRY Gangnam, 75% of subcision patients receive combination protocols for comprehensive scar revision.
- Long-Lasting Structural Results Once fibrous tethers are severed and new collagen fills the space, results are permanent. Re-tethering rates drop below 10% when subcision is combined with Juvelook PDLLA filler injection at RE:BERRY Gangnam.
| Timeline | What to Expect |
|---|---|
| Day 1-3 | Bruising and swelling at subcision sites are expected. This is a normal healing response — the sub-dermal hematoma supports scar elevation. Apply cold compresses. Avoid blood thinners and alcohol. |
| Day 4-7 | Bruising transitions from purple to yellow-green. Swelling subsides significantly. Scars already appear elevated compared to pre-treatment. Gentle skincare resumed. |
| Week 2-3 | Bruising fully resolves. Initial scar elevation stabilizes. Some residual firmness beneath treated scars is normal and indicates collagen formation. SPF 30+ daily. |
| Month 1-2 | Collagen remodeling accelerates in subcised areas. Juvelook PDLLA degradation triggers fibroblast activation. 40-50% scar improvement typically visible at 6-week assessment. |
| Month 3-6 | Peak collagen synthesis from Juvelook PDLLA. Scar depth reduction reaches 50-70% for rolling scars. Second subcision session may be scheduled for residual tethered scars. |
| Month 6-12 | Final structural remodeling completes. Results are considered permanent for released tethers. Annual assessment recommended. Touch-up subcision for any newly identified tethered scars. |

The Science Behind Subcision for Acne Scars
Peer-reviewed evidence supporting subcision as a cornerstone of acne scar revision.
Mechanism of Subcision: Fibrous Tether Release
Subcision (subcutaneous incisionless surgery) was first described by Orentreich and Orentreich in 1995 as a technique for releasing dermal scars tethered to underlying tissue. A tribeveled hypodermic needle is inserted parallel to the skin surface at the dermal-subdermal junction (3-5mm depth) and moved in a fanning motion to sever the fibrous bands that anchor rolling and bound-down acne scars. The resultant hematoma beneath the released scar creates a connective tissue matrix that promotes new collagen deposition, structurally supporting the elevated skin surface. Subcision for acne scars is particularly effective for rolling scars, which are defined by their undulating, wave-like appearance caused by fibrous attachments to the subcutaneous layer.
Subcision Combined with PDLLA Filler Injection
Contemporary subcision protocols at RE:BERRY Gangnam combine tether release with Juvelook PDLLA filler injection into the subcised space. This dual approach addresses the two failure modes of subcision alone: re-tethering (fibrous bands reforming during healing) and insufficient volume (flat hematoma resorption without volumetric gain). PDLLA microspheres provide sustained collagen stimulation over 8-24 months as they undergo hydrolytic degradation, depositing new type I and III collagen into the space previously occupied by scar tissue. Clinical studies demonstrate that subcision with concurrent filler injection achieves 40-70% scar depth improvement versus 25-50% for subcision alone.
Multi-Modal Scar Revision Protocols
For patients with mixed acne scar morphologies — combining rolling, boxcar, and icepick scars — subcision serves as the structural foundation of a multi-modal protocol. Rolling and tethered scars are treated with subcision and filler, while boxcar scars respond to Potenza RF microneedling or TCA CROSS (trichloroacetic acid chemical reconstruction of skin scars), and icepick scars may require punch excision or high-concentration TCA. This compartmentalized approach, treating each scar type with the modality best suited to its morphology, consistently outperforms single-modality treatments in comparative studies.
Clinical Evidence and Outcomes
A systematic review by Barikbin et al. (2017) analyzed 14 studies involving 680 patients and confirmed subcision as an effective standalone and adjunctive treatment for atrophic acne scars, with a mean improvement of 51% across all scar types. Aalami-Harandi et al. (2019) demonstrated in a split-face RCT that subcision combined with platelet-rich plasma achieved 72% improvement versus 45% for subcision alone. Alam et al. (2018) reported that subcision with hyaluronic acid filler produced statistically significant scar improvement at 6 months in a multicenter randomized trial, establishing the superiority of subcision-plus-filler over sham treatment.

What Our Patients Say About Subcision
“I spent thousands on laser treatments back home in Singapore with minimal improvement on my rolling cheek scars. Dr. Ryu explained that the scars were tethered and needed subcision first. After two sessions with Juvelook, the difference is remarkable — my scars are genuinely shallower, not just smoother on the surface. I wish I had come to RE:BERRY Gangnam sooner.”
“The subcision procedure was much less intimidating than I expected. The numbing injection meant I felt zero pain during the actual needle release. Bruising lasted about 5 days but was easily covered with concealer. At my 8-week follow-up, even Dr. Oh seemed pleased with how much the scars had improved. The ₩490,000 Potenza + Juvelook combination was incredibly good value.”
“My dermatologist in Melbourne recommended subcision for my tethered acne scars but quoted AUD $2,500 per session. RE:BERRY Gangnam offered the same procedure combined with Juvelook collagen stimulation for a fraction of the price. Three sessions over six months and my skin has transformed. The English-speaking coordinators made everything seamless.”
Frequently Asked Questions About Subcision for Acne Scars
Expert answers from RE:BERRY Gangnam’s subcision and scar revision specialists.
₩490,000 for Potenza + Juvelook (or Exosome) combination and ₩1,290,000 for the Reberry Signature Acne Package at RE:BERRY Gangnam. Juvelook 4cc as a subcision add-on is ₩340,000. All prices valid April-June 2026. Exact pricing depends on the number of scars and treatment area.
2-3 subcision sessions spaced 6-8 weeks apart is typical for optimal results at RE:BERRY Gangnam. Mild tethering may resolve in 1 session, while extensive rolling scars across both cheeks typically require 3 sessions. Dr. Yoon-Gon Ryu assesses progress at each visit and adjusts the protocol accordingly.
1-2 on a 10-point pain scale during the procedure itself because local anesthesia (lidocaine + epinephrine) is injected directly beneath each scar cluster. The numbing injection causes a brief sting (3-5 seconds). Once numb, you feel pressure but no pain during the Nokor needle release.
5-7 days of bruising is the primary downtime after subcision at RE:BERRY Gangnam. Bruising starts purple on day 1-2, transitions to yellow-green by day 4-5, and resolves completely by day 7-10. Swelling subsides within 48-72 hours. Concealer can be applied after 24 hours if needed.
Yes, most international patients fly home 24-48 hours after subcision at RE:BERRY Gangnam. Cabin pressure does not affect subcision results. The bruising is cosmetic, not medical. We recommend scheduling your departure 1-2 days after the procedure for maximum comfort.
Rolling scars and tethered (bound-down) scars respond best to subcision, with 40-70% depth improvement. The lateral stretch test confirms tethering — if your scar flattens when surrounding skin is stretched, subcision is indicated. Boxcar scars respond moderately; icepick scars require different approaches like TCA CROSS or punch excision.
For tethered and rolling acne scars, subcision achieves 40-70% improvement versus 25-45% for acne laser alone (Potenza RF). Lasers are superior for shallow surface texture irregularities. The best results come from combining subcision with laser — which is why RE:BERRY Gangnam’s Signature Acne Package includes both modalities.
Juvelook PDLLA injected into the subcised space serves 3 functions: (1) prevents re-tethering by occupying the released space during healing, (2) provides immediate volumetric elevation of depressed scars, (3) stimulates sustained collagen production over 8-24 months. Without filler, re-tethering rates increase to 30-40%.
Yes, 75% of subcision patients at RE:BERRY Gangnam receive concurrent Potenza RF microneedling. The combination protocol is ideal for mixed scar types: subcision releases tethered rolling scars while Potenza RF addresses shallow boxcar scars and overall texture. Both procedures can be performed in the same session.
Yes. Unlike ablative lasers, subcision carries minimal post-inflammatory hyperpigmentation (PIH) risk because it works entirely below the epidermis without disrupting melanocyte-containing surface layers. Patients with Fitzpatrick skin types IV-VI are excellent subcision candidates at RE:BERRY Gangnam.
40-50% immediate improvement is visible once bruising resolves (7-10 days) as released scars elevate. Juvelook collagen induction adds another 20-30% improvement over months 2-6. Maximum results are typically achieved at 6 months post-subcision when PDLLA-stimulated collagen synthesis peaks.
Icepick scars respond poorly to subcision alone because they are narrow and deep without significant tethering. Dr. Ryu treats icepick scars with TCA CROSS (trichloroacetic acid chemical reconstruction) or Pico Fraxel laser rather than subcision. For patients with mixed rolling + icepick scars, a combined protocol addresses each type specifically.
Less than 3% complication rate for subcision at RE:BERRY Gangnam. Expected side effects (bruising, swelling) are temporary. Rare complications include nodule formation (less than 1%, treatable with massage) and asymmetry (correctable with follow-up session). Nerve damage risk is negligible with proper depth control.
Subcision is non-excisional (no tissue removal, no sutures, no linear scars) and best for rolling/tethered scars covering broad areas. Punch excision removes individual deep scars surgically and requires suturing, best for isolated deep icepick scars. Dr. Ryu may recommend both techniques in a single protocol for comprehensive scar revision.
Yes, subcision for acne scars is performed on the back, chest, and shoulders at RE:BERRY Gangnam. Body acne scars are often more deeply tethered than facial scars, requiring slightly deeper needle depth (4-6mm). Pricing is customized based on treatment area and scar density.
Before: stop blood thinners (aspirin, ibuprofen, fish oil) 7 days prior, avoid alcohol 48 hours before. After: no intense exercise for 72 hours, apply cold compresses for 48 hours, avoid hot sauna for 1 week, use SPF 30+ daily. Full aftercare instructions provided in 8 languages.
Yes, once fibrous tethers are severed and new collagen fills the space, the structural correction is permanent. Re-tethering rates drop below 10% when subcision is combined with Juvelook PDLLA at RE:BERRY Gangnam. However, the skin continues aging normally, so overall skin quality maintenance (skin boosters, sunscreen) is recommended.
3 key advantages at RE:BERRY Gangnam: (1) all subcision procedures physician-performed by Dr. Yoon-Gon Ryu or Dr. Yejin Oh — never delegated; (2) Juvelook KOL certification ensures optimal filler technique and authentic product sourcing; (3) comprehensive scar mapping and progress photography at every visit for transparent outcome tracking.
Yes, plan 2-3 days in Seoul for a single subcision session at RE:BERRY Gangnam. Day 1 for the procedure, day 2-3 for initial recovery. Bruising is cosmetic and does not prevent travel. For multi-session protocols, many patients schedule visits 6-8 weeks apart across separate trips to Korea.
The Nokor needle is an 18-gauge tribeveled hypodermic needle specifically designed for subcision. Its three cutting edges allow efficient severing of fibrous bands with minimal tissue trauma. Dr. Ryu uses the Nokor needle technique as described in the original Orentreich method, considered the gold standard for subcision since 1995.
Yes, subcision is effective for any tethered or depressed scar — including chicken pox scars, traumatic scars, and post-surgical scars. The mechanism is identical: severing fibrous bands and filling the space with collagen-stimulating filler. Assessment at RE:BERRY Gangnam determines suitability during consultation.
Subcision releases the structural tethers while skin booster injection improves overall skin quality (hydration, collagen density, texture). Dr. Ryu recommends subcision first, then skin booster injection 2-3 weeks later once bruising resolves. The combination addresses both the structural and textural components of acne scarring.

40-60% lower than equivalent subcision procedures in the US (USD $800-2,000/session), UK (GBP 500-1,500), and Australia (AUD $1,000-2,500). Korea’s competitive aesthetic market and high procedure volume drive pricing advantages. RE:BERRY Gangnam’s subcision with Juvelook from ₩490,000 represents exceptional value for physician-performed scar revision.
Yes, with 3-4 weeks spacing recommended. Complete the subcision and scar revision phase first, then schedule Thermage FLX (₩1,990,000) or Ultherapy Prime (₩490,000/100 shots) once scar healing is complete. Many international patients at RE:BERRY Gangnam combine scar revision with anti-aging lifting during their Seoul visit.
