Acne Scar Treatments in Gangnam Seoul
Icepick, boxcar, and rolling acne scars require multi-layer intervention beyond what surface peels or topical serums can achieve. RE:BERRY Gangnam deploys a physician-directed combination of Potenza RF microneedling, Juvelook PDLLA volumetric filling, subcision, and Pico Fraxel laser resurfacing to restructure damaged collagen architecture from the dermis up. Acne scar treatments starting at ₩490,000, two minutes from Gangnam Station Exit 10.
What Are Acne Scar Treatments at RE:BERRY Gangnam?
Acne scar treatments at RE:BERRY Gangnam combine Potenza RF microneedling, Juvelook PDLLA collagen induction, subcision, and Pico Fraxel resurfacing to achieve 35-60% scar depth reduction across icepick, boxcar, and rolling scars — starting at ₩490,000 per session with 24-48 hours downtime under physician-only protocols.
Medical Director Dr. Yoon-Gon Ryu classifies every acne scar using the ECCA grading system and dermoscopic imaging before selecting the optimal combination of acne scar treatments for each patient. Tethered rolling scars respond best to subcision plus Juvelook PDLLA volumetric filling; icepick scars require focused Pico Fraxel fractional energy to break fibrotic bands; and boxcar scars benefit from Potenza RF microneedling that remodels the scar floor through controlled collagen induction. At RE:BERRY Gangnam, all acne scar treatments are performed exclusively by licensed physicians and customized based on scar morphology, Fitzpatrick skin type (I-VI), and patient goals. The clinic’s 14,000 sq ft facility houses over 30 medical devices, ensuring the right tool for every scar type. Whether you are an international traveler seeking an intensive one-day scar protocol or a local patient planning a multi-session program, our 8-language coordination team manages everything from consultation booking to aftercare instructions.

How Acne Scar Treatments Work at RE:BERRY Gangnam
A physician-directed multi-step acne scar protocol targeting every layer of damaged skin architecture.

Scar Mapping & ECCA Grading
Dr. Yoon-Gon Ryu performs high-magnification dermoscopic analysis to classify each scar by type (icepick, boxcar, rolling, hypertrophic), depth (superficial <0.5mm, moderate 0.5-2mm, deep >2mm), and tethering characteristics. Scars are scored on the ECCA (Echelle d’Evaluation Clinique des Cicatrices d’Acne) grading system to quantify severity and track improvement. A cross-polarized light analysis reveals subsurface collagen disruption invisible to the naked eye. This 20-minute diagnostic session determines which combination of acne scar treatments will deliver the most efficient results for your specific scar profile at RE:BERRY Gangnam.

Subcision for Tethered Scars
Rolling and deep boxcar scars anchored by fibrotic bands require subcision — a minimally invasive technique where a hypodermic needle or Nokor needle is inserted subdermally to sever the fibrous attachments pulling the scar surface downward. At RE:BERRY Gangnam, subcision is performed under local anesthesia with precise depth control. Releasing these tethers allows the scar floor to elevate naturally, creating a foundation for subsequent volumetric filling. This step alone can improve rolling scar depth by 25-40% and is a critical prerequisite before Rejuran or Juvelook injection.

Potenza RF Microneedling + Exosome Therapy
Potenza delivers bipolar radiofrequency energy through gold-tipped microneedles at adjustable depths (0.5-3.5mm), creating controlled thermal zones in the scar bed. The RF energy denatures disorganized scar collagen and triggers a wound-healing cascade that replaces it with organized type I and III collagen fibers. Exosome solution containing growth factors (EGF, FGF, VEGF) is driven into the micro-channels during the acne scar treatment for accelerated cellular repair. Each session covers the full scarred area in a systematic grid pattern to ensure uniform remodeling density.

Juvelook PDLLA + Pico Fraxel Resurfacing + LDM Recovery
Juvelook (poly-D,L-lactic acid microspheres in HA gel) is micro-injected into atrophic scars to provide immediate volumetric support plus progressive neocollagenesis over 8-24 months. For narrow icepick scars, Pico Fraxel delivers picosecond fractional energy to break fibrotic cores and stimulate fresh collagen bridging. The session concludes with LDM (Local Dynamic Micro-massage) ultrasound at 3-10 MHz for anti-inflammatory recovery and lymphatic drainage. The complete acne scar treatments protocol takes 60-90 minutes at RE:BERRY Gangnam depending on the treatment area and scar severity.
What to Expect from Acne Scar Treatments
- Multi-Scar-Type Coverage RE:BERRY Gangnam’s acne scar treatments protocol addresses all three primary scar morphologies — icepick, boxcar, and rolling — in a single session rather than treating one type at a time.
- 35-60% Scar Depth Reduction Clinical measurements show Potenza RF microneedling combined with Juvelook PDLLA achieves 35-60% improvement on the ECCA grading scale after 2-3 sessions spaced 4 weeks apart.
- Progressive Collagen Remodeling Juvelook PDLLA microspheres stimulate neocollagenesis that continues for 8-24 months post-injection, meaning visible improvement progresses well beyond the treatment course.
- Minimal Downtime for International Visitors 24-48 hours of mild redness is typical. No peeling, no crusting. Patients can fly home same day after acne scar treatments and apply makeup after 24 hours.
- Safe for Fitzpatrick III-VI Skin Types Potenza’s insulated gold-tipped needles deliver energy beneath the epidermis, reducing post-inflammatory hyperpigmentation risk critical for Asian and darker skin tones.
- Physician-Only Execution All acne scar treatments at RE:BERRY Gangnam are performed by Dr. Yoon-Gon Ryu or Dr. Yejin Oh — never delegated to nurses or technicians.
| Timeline | What to Expect |
|---|---|
| Day 1-2 | Mild redness, pinpoint swelling at needle entry sites. Cool compresses and SPF 30+ required. Avoid makeup for 24 hours. Subcision sites may show mild bruising for 3-5 days. |
| Week 1-2 | Redness fully resolves. Skin texture begins evening out as early collagen remodeling initiates. Subcision-released scars visibly elevate as tethers stay severed. |
| Week 3-4 | Potenza RF-induced collagen deposition becomes measurable on dermoscopy. Scar edges soften. Ideal timing for second acne scar treatments session if a multi-session protocol was planned. |
| Month 2-3 | Juvelook PDLLA collagen cascade peaks. Significant volumetric improvement in rolling and boxcar scars. Icepick scars show narrowing from Pico Fraxel collagen bridging. |
| Month 3-6 | Maximum clinical improvement reached for most patients. ECCA scores reduced by 35-60%. Skin tone and texture approaching optimal. Maintenance sessions every 3-4 months for severe cases. |
| Month 6-24 | Juvelook PDLLA microspheres continue gradual degradation with ongoing neocollagenesis. Long-term collagen architecture stabilizes. Annual touch-up may benefit deep scars. |

The Science Behind Acne Scar Treatments
Peer-reviewed evidence supporting multi-modality acne scar remodeling protocols.
RF Microneedling for Atrophic Acne Scars
Fractional radiofrequency microneedling has emerged as a first-line acne scar treatment for atrophic scars because it targets the mid-to-deep dermis (0.5-3.5mm) without ablating the epidermis. The Potenza system delivers bipolar RF energy through insulated gold-tipped microneedles, creating controlled thermal coagulation zones (60-70 degrees C) that denature disorganized scar collagen and initiate the wound-healing cascade. Histological studies confirm a 2.1-fold increase in dermal collagen density at 3 months post-treatment, with newly synthesized fibers demonstrating organized lattice architecture rather than the chaotic cross-linking pattern characteristic of scar tissue. This mechanism makes RF microneedling particularly effective for boxcar scars where the scar floor needs elevation through volumetric collagen expansion.
Subcision Combined with Volumetric Fillers
Rolling acne scars are defined by dermal tethering — fibrotic bands anchor the skin surface to deeper structures, creating a wave-like undulation. Subcision mechanically severs these bands, but without a volumetric scaffold the tethers often reform within weeks. The combination of subcision followed by immediate Juvelook PDLLA injection into the newly released space creates a physical barrier against re-tethering while simultaneously stimulating long-term neocollagenesis. A 2020 split-face study demonstrated that subcision plus PDLLA filler achieved 58% improvement in rolling scar depth versus 31% with subcision alone at 6-month follow-up, confirming the synergistic value of this acne scar treatments combination approach used at RE:BERRY Gangnam.
Picosecond Fractional Laser for Icepick Scars
Icepick scars — narrow (less than 2mm), deep, V-shaped depressions extending into the reticular dermis or subcutis — resist most conventional acne scar treatments because their fibrotic cores are too narrow for RF needles and too deep for superficial peels. Picosecond fractional laser technology (Pico Fraxel) delivers ultra-short pulse durations (375-750 picoseconds) that create laser-induced optical breakdown (LIOB) micro-cavities in the scar tissue, fragmenting fibrotic cores without excessive thermal damage. These micro-cavities trigger collagen bridging from the scar walls inward, gradually narrowing the scar aperture. Clinical data shows 40-55% icepick scar improvement after 3-4 Pico Fraxel sessions, with PIH rates below 5% in Fitzpatrick III-V patients — a significant advantage over ablative CO2 fractional lasers.

Clinical Evidence Summary
A 2019 systematic review analyzing 28 randomized controlled trials confirmed that RF microneedling produces statistically superior acne scar improvement compared to non-ablative fractional lasers with fewer adverse effects in pigmented skin. Alam et al. (2018) reported that 90% of patients achieved clinically meaningful improvement (at least 1 grade on the Goodman-Baron scale) after 3 sessions of RF microneedling. For PDLLA-based volumetric remodeling, Goldberg et al. (2020) demonstrated sustained scar improvement at 18 months post-injection, supporting the long-duration collagen-stimulating mechanism of Juvelook in acne scar treatments protocols.

What Our Patients Say About Acne Scar Treatments
“After 10 years of living with deep boxcar scars across both cheeks, three sessions of Potenza RF plus Juvelook at RE:BERRY Gangnam transformed my skin. The scars are noticeably shallower and my skin texture is smoother than it has been since high school. Dr. Ryu’s scar mapping approach was incredibly thorough.”
“I had severe rolling scars that no clinic in Bangkok could improve. The subcision plus Juvelook combination at RE:BERRY Gangnam released the tethered scars after just one session. By the time I returned for my second visit three months later, even my friends noticed the difference.”
“The Pico Fraxel treatment for my icepick scars was something I could not find at this quality level in Europe. Three sessions, minimal downtime each time, and my narrow deep scars have visibly filled in. The 8-language support made the entire process seamless.”
