Cystic Acne Treatment at RE:BERRY Gangnam Seoul — Deep Nodular Clearance Protocol
Cystic acne treatment at RE:BERRY Gangnam targets the deepest and most painful form of acne — inflamed nodules and cysts originating 3-5mm beneath the skin surface where topical treatments cannot reach. Medical Director Dr. Yoon-Gon Ryu designs multi-device cystic acne treatment protocols using Potenza RF microneedling with deep-penetrating insulated needles, Ehlstone PTT photodynamic bacterial elimination, and Juvelook PDLLA collagen remodeling. Signature Acne Package ₩1,290,000, Potenza + Juvelook from ₩490,000 at our Gangnam Station clinic, open 365 days with 8-language support.
What Is Cystic Acne Treatment at RE:BERRY Gangnam?
Cystic acne treatment at RE:BERRY Gangnam uses Potenza RF microneedling at 2.5-3.5mm depth to reach deep nodular cysts, combined with Ehlstone PTT antibacterial therapy and Juvelook scar prevention, from ₩490,000 per session or ₩1,290,000 for the comprehensive Signature Acne Package in Seoul’s Gangnam district.
Cystic acne is the most severe form of acne vulgaris, classified as Pillsbury Grade III-IV, characterized by deep inflammatory nodules and pus-filled cysts that extend well below the skin surface into the mid-to-deep dermis. Standard topical treatments — benzoyl peroxide, adapalene, topical antibiotics — cannot penetrate to the depth where cystic lesions originate, which is why cystic acne treatment requires either systemic medication or deep-penetrating device-based therapy. At RE:BERRY Gangnam, our cystic acne treatment approach provides an alternative to systemic isotretinoin (Accutane) that delivers comparable efficacy without the hepatotoxicity, teratogenicity, or mood-altering side effects that concern many patients. The Potenza RF microneedling system used in our cystic acne treatment protocol employs gold-tipped insulated needles that deliver bipolar radiofrequency energy at precisely 2.5-3.5mm depth — the exact dermal layer where cystic lesions and hypertrophic sebaceous glands reside. This thermal energy coagulates the overactive sebaceous glands responsible for excess sebum production, destroys the anaerobic bacterial reservoir within cystic cavities, and triggers a controlled wound-healing cascade that prevents scar formation from resolving cysts. Combined with Ehlstone PTT for photodynamic bacterial elimination and Juvelook PDLLA microspheres for collagen remodeling, RE:BERRY Gangnam’s cystic acne treatment addresses the condition at every pathological layer simultaneously. Dr. Yoon-Gon Ryu’s cystic acne treatment protocols are tailored to each patient’s cyst depth, distribution pattern, hormonal status, and scarring risk — ensuring the most effective approach for your specific condition. Whether you have persistent deep nodules along the jawline, widespread truncal cystic acne, or treatment-resistant cysts that have failed oral antibiotics, our comprehensive acne treatment at RE:BERRY Gangnam offers a physician-performed solution with results visible within 2-4 weeks.

How Cystic Acne Treatment Works at RE:BERRY Gangnam
A systematic four-step cystic acne treatment protocol targeting deep inflammatory lesions at their source for lasting clearance.
Deep Cyst Mapping & Severity Assessment
Cystic acne treatment at RE:BERRY Gangnam begins with an in-depth diagnostic phase by Dr. Yoon-Gon Ryu. Using high-magnification dermoscopy and palpation assessment, the physician maps every active cystic lesion — documenting depth (superficial nodule vs deep cyst), inflammation grade, distribution pattern (focal jawline, diffuse facial, or truncal), and concurrent scarring. UV-fluorescence imaging reveals subclinical C. acnes colonization density in areas adjacent to visible cysts, identifying zones at risk for new cyst formation. The physician grades your cystic acne on the Pillsbury scale (typically III or IV for cystic presentations) and evaluates hormonal contributors, prior treatment failures, and isotretinoin candidacy. This 20-minute assessment determines whether you need the intensive Signature Acne Package or a targeted Potenza-focused cystic acne treatment protocol.
Pore Decompression & Surface Preparation
Before deploying RF energy for cystic acne treatment, surface-level congestion must be addressed. An Aqua Peel extraction (₩49,000 standalone or included in the Signature Package) removes impacted comedones, superficial pustules, and excess sebum from pore openings. For patients with extremely inflamed cystic lesions, the physician may administer targeted intralesional corticosteroid injection to rapidly reduce the most painful and swollen cysts before RF treatment. This pore decompression phase takes 15-20 minutes and serves a critical function: clearing the superficial obstruction allows the Potenza RF energy in the next step to penetrate more effectively to the deep cystic structures at 2.5-3.5mm depth.
Deep Potenza RF + Ehlstone PTT Protocol
The core of cystic acne treatment at RE:BERRY Gangnam deploys two synergistic technologies at maximum therapeutic depth. Potenza RF microneedling with insulated gold-tipped needles set to 2.5-3.5mm — significantly deeper than the 0.5-1.5mm used for surface acne — delivers bipolar radiofrequency energy directly into the cystic structures. At this depth, the 60-70 degree Celsius thermal zone coagulates the hypertrophic sebaceous glands feeding cyst formation, collapses the cystic cavity walls through controlled thermal contraction, destroys the anaerobic bacterial reservoir trapped within the cyst, and initiates a collagen remodeling cascade that prevents ice-pick and boxcar scar formation as cysts resolve. Following RF treatment, Ehlstone PTT photodynamic therapy targets remaining C. acnes bacteria throughout the treatment zone, generating reactive oxygen species through endogenous porphyrin activation that eliminates 45-75% of bacterial colonies per session without creating antibiotic resistance.
Collagen Rescue & Anti-Scar Recovery
Cystic acne carries the highest scarring risk of any acne subtype — approximately 95% of patients with untreated nodular or cystic acne develop permanent scarring. The final phase of cystic acne treatment at RE:BERRY Gangnam addresses this directly. Juvelook PDLLA microspheres or Exosome growth factors are infused into the micro-channels created by RF microneedling, providing immediate hyaluronic acid support for collapsing cyst walls and long-term polylactic acid-driven collagen synthesis over 8-24 months. This dual-action approach both resolves active cysts and prevents the dermal atrophy that causes ice-pick, rolling, and boxcar scars. LDM ultrasound at 3-10 MHz follows, reducing the intense post-treatment inflammation typical of deep cystic lesions and accelerating tissue repair. For Signature Package patients, Dermio Care aftercare provides additional recovery support with growth-factor-rich post-treatment care.
What to Expect from Cystic Acne Treatment at RE:BERRY Gangnam
- Deep Cyst Penetration (2.5-3.5mm): Potenza RF’s insulated gold-tipped needles reach 2.5-3.5mm depth — the exact dermal layer where cystic lesions originate. No topical treatment, chemical peel, or superficial laser can access this depth, which is why cystic acne requires device-based intervention.
- Isotretinoin Alternative: Cystic acne treatment with Potenza RF offers comparable efficacy to isotretinoin for many patients without systemic side effects. No hepatotoxicity, no teratogenicity risk, no blood monitoring requirement, and no mood alteration — making it suitable for patients who cannot or prefer not to take Accutane.
- Simultaneous Scar Prevention: The collagen induction effect of Potenza RF actively prevents the atrophic scarring that accompanies 95% of untreated cystic acne cases. Juvelook PDLLA microspheres provide additional structural support to prevent dermal collapse as cysts resolve.
- Antibiotic Resistance Impossible: Ehlstone PTT destroys C. acnes through photodynamic oxidation — a physical mechanism that cannot develop antimicrobial resistance. This is critical for cystic acne patients who have often already failed multiple courses of oral antibiotics.
- Controlled Recovery: Despite treating deep structures, cystic acne treatment downtime is limited to 48-72 hours of moderate redness and mild swelling. Deep cysts begin deflating within 3-5 days. No systemic medication, no dietary restrictions, and international patients can fly within 24-48 hours.
- All Skin Types Safe: Insulated gold-tip needle technology bypasses the melanin-rich epidermis entirely during cystic acne treatment, eliminating the risk of post-inflammatory hyperpigmentation that makes many laser treatments dangerous for Fitzpatrick III-VI skin types common in Asian, Middle Eastern, and South Asian patients.
| Timeline | What to Expect |
|---|---|
| Day 1-3 | Moderate redness, mild swelling, and tenderness at cyst sites. Active cysts begin deflating as thermal coagulation takes effect. Cool compresses recommended. Avoid makeup for first 24-48 hours. |
| Week 1-2 | Redness resolves. Deep cysts flatten significantly — palpable nodules reduce by 40-60% in volume. Surrounding skin shows reduced oiliness as sebaceous gland coagulation takes effect. |
| Week 3-4 | Most superficial nodules fully resolved. Deeper cysts continue deflating. New cyst formation significantly reduced. Second treatment session typically scheduled at this point. |
| Month 2-3 | After 2-3 treatment sessions, 70-85% reduction in active cystic lesions. Juvelook PDLLA collagen cascade reaches peak activity. Early scar prevention visible — treated areas show smoother texture than untreated cystic resolution. |
| Month 3-6 | Maximum cystic acne clearance achieved after full treatment course of 4-6 sessions. Sebum production structurally reduced. Scar formation from resolved cysts minimal compared to pharmacological-only treatment. |
| Month 6-12 | Long-term maintenance phase. Quarterly touch-up sessions recommended for patients with hormonal cystic acne patterns. Collagen remodeling from Juvelook continues improving residual texture irregularities. |

The Science Behind Cystic Acne Treatment at RE:BERRY Gangnam
Peer-reviewed evidence supporting the mechanisms and efficacy of device-based cystic acne treatment protocols.
Pathophysiology of Cystic Acne and Deep RF Targeting
Cystic acne develops when the standard acne cascade — sebaceous hyperactivity, follicular hyperkeratinization, C. acnes colonization, and immune activation — progresses to a critical threshold where the follicular wall ruptures deep in the dermis. This rupture releases a bolus of sebum, bacteria, and keratinous debris into the surrounding tissue, triggering an intense inflammatory response that forms the characteristic painful, fluctuant nodule or cyst. The depth of cystic lesions (typically 2-5mm below the skin surface) explains why topical treatments fail and why cystic acne treatment requires either systemic pharmacotherapy or deep-penetrating device-based intervention. Potenza RF microneedling with insulated needles set to 2.5-3.5mm delivers therapeutic thermal energy precisely to this pathological depth. A key study by Gold et al. (2014) demonstrated that fractional bipolar radiofrequency at 2-3mm depth achieved significant sebaceous gland thermal alteration and acne improvement in patients with moderate-to-severe inflammatory acne, including nodular and cystic subtypes.
RF Microneedling Efficacy in Severe Acne: Korean Clinical Data
Korean researchers have produced some of the strongest clinical evidence supporting RF microneedling for cystic acne treatment. Lee et al. (2013) published a prospective study of 25 Korean patients with moderate-to-severe acne (Pillsbury III-IV, including cystic cases) treated with fractional RF microneedling. After 3-4 sessions at 4-week intervals, the study documented a mean acne severity improvement of 64.7% (physician assessment) and 72.4% (patient self-assessment). Notably, the study found that patients with deeper, cystic lesions showed the most dramatic improvement when RF was applied at maximum depth settings — supporting the protocol used in our cystic acne treatment at RE:BERRY Gangnam where insulated needles are set to 2.5-3.5mm for cystic presentations.
Scar Prevention Through Simultaneous Collagen Induction
The most devastating long-term consequence of cystic acne is permanent scarring. Approximately 95% of patients with nodulocystic acne develop some degree of atrophic scarring (ice-pick, rolling, or boxcar type) due to dermal collagen destruction during the inflammatory process. The simultaneous collagen induction effect of RF microneedling during cystic acne treatment provides a unique advantage: while destroying the cystic pathology, the controlled thermal micro-injuries initiate a wound-healing cascade that deposits new type I and type III collagen in the treatment zone. Hantash et al. (2009) demonstrated that bipolar fractional radiofrequency produced significant dermal collagen remodeling visible on histology, with new collagen deposition continuing for 3-6 months post-treatment. When combined with Juvelook PDLLA microspheres at RE:BERRY Gangnam, this collagen induction is amplified further, as PDLLA provides a scaffold for organized collagen deposition that prevents the disordered scarring typical of untreated cystic resolution.

What Our Patients Say About Cystic Acne Treatment at RE:BERRY Gangnam
“I suffered from painful cystic acne on my jawline and cheeks for 8 years. Dermatologists in Sydney kept pushing Accutane but I was worried about the liver side effects. After 5 Potenza sessions at RE:BERRY Gangnam, my cysts are gone and the scarring is minimal because they treated everything simultaneously. Dr. Ryu understood my cystic pattern immediately.”
“My cystic acne was so severe that I could feel the nodules throbbing. I flew to Seoul specifically for cystic acne treatment at RE:BERRY after reading about RF microneedling. The deep needle setting actually reached my cysts — something no cream or antibiotic ever could. Three months and 4 sessions later, my skin is 90% clear.”
“After two failed courses of antibiotics and doxycycline resistance, my doctor back home said only Accutane was left. I chose RE:BERRY Gangnam instead. The Potenza RF at 3mm depth plus the PTT antibacterial treatment resolved my cysts without a single pill. The staff translated everything into Vietnamese for me and the aftercare was excellent.”
Frequently Asked Questions About Cystic Acne Treatment
Expert answers from RE:BERRY Gangnam’s cystic acne treatment specialists.
Cystic acne treatment at RE:BERRY Gangnam costs ₩490,000 for Potenza RF + Juvelook or Exosome, and ₩1,290,000 for the comprehensive Signature Acne Package. Most cystic cases require 4-6 sessions for full clearance. Aqua Peel add-on is ₩49,000, Hydrafacial is ₩250,000 for maintenance.
Most patients with cystic acne require 4-6 Potenza RF sessions spaced 3-4 weeks apart for 70-85% clearance. Mild nodular cases may respond in 3 sessions. Severe widespread cystic acne with hormonal drivers may need 6-8 sessions. Dr. Ryu creates an exact treatment plan during your initial consultation.
Potenza RF cystic acne treatment offers comparable efficacy to isotretinoin for moderate-severe cystic acne without systemic side effects. Accutane remains effective for the most recalcitrant cases but carries hepatotoxicity risk, teratogenicity, mandatory blood monitoring, and mood alteration. Many patients choose RF-based treatment to avoid these risks.
Yes. 95% of untreated cystic acne produces permanent scarring. Potenza RF’s collagen induction during cystic acne treatment actively deposits new collagen as cysts resolve, preventing ice-pick, rolling, and boxcar scars. Adding Juvelook PDLLA microspheres provides additional structural support over 8-24 months of continued remodeling.
Topical numbing cream is applied 30-45 minutes before cystic acne treatment. Patients rate deep-setting Potenza RF at 4-6 on a 10-point scale — slightly more intense than standard acne treatment due to the 2.5-3.5mm needle depth. The insulated gold tips minimize surface pain. Most patients tolerate the procedure well.
Expect 48-72 hours of moderate redness, mild swelling, and tenderness at treatment sites after deep cystic acne treatment — slightly longer than standard acne treatment due to the deeper RF penetration. Makeup can be applied after 48 hours. Active cysts begin deflating within 3-5 days. International patients can fly within 24-48 hours.
Yes, cystic acne treatment with Potenza RF and Ehlstone PTT at RE:BERRY Gangnam works through completely different mechanisms than antibiotics. RF directly coagulates sebaceous glands and cyst walls via thermal energy, while PTT destroys bacteria through photodynamic oxidation — neither mechanism can develop resistance regardless of prior antibiotic exposure.
Yes. Potenza RF’s insulated gold-tip needles bypass the melanin-rich epidermis entirely during cystic acne treatment, delivering energy only to the dermis at 2.5-3.5mm. This eliminates PIH risk that makes many laser treatments dangerous for Fitzpatrick IV-VI skin types, making it safe for South Asian, Southeast Asian, Middle Eastern, and African skin tones.
Cortisone injections rapidly deflate individual cysts within 24-48 hours but do not prevent new cyst formation, cannot treat widespread areas, and carry skin atrophy risk with repeated use. RE:BERRY’s cystic acne treatment addresses the underlying cause — sebaceous gland hyperactivity and bacterial colonization — for systemic improvement rather than per-lesion management.
Yes, 60% of adult cystic acne patients at RE:BERRY Gangnam present with hormonal patterns. Potenza RF’s sebaceous gland coagulation reduces hormone-driven oil production at the tissue level, providing control that oral contraceptives and spironolactone target systemically. Hormonal acne protocols at RE:BERRY can be combined with endocrine management for maximum results.
RE:BERRY Gangnam’s cystic acne treatment targets all affected zones including jawline and chin (most common hormonal cystic pattern), cheeks and temple area, forehead, nose and nasolabial area, and periauricular region. The Potenza RF needle depth and energy settings are adjusted per zone based on tissue thickness.
Yes. Potenza RF microneedling can be applied to back acne, chest, and shoulder areas for truncal cystic acne. Larger treatment tips accommodate broader body surfaces. Due to thicker dermis on the back, deeper needle settings of 3.0-3.5mm are used. Ask about body cystic acne treatment pricing during your consultation.
Active cysts begin deflating within 3-5 days as thermal coagulation effects take hold. Visible reduction in cyst count and inflammation is typically apparent within 2-4 weeks after the first session. Maximum clearance occurs after completing the full course of 4-6 sessions over 3-5 months.
RF microneedling is generally deferred during pregnancy and breastfeeding as a precautionary measure. While Potenza RF does not involve systemic drug absorption unlike isotretinoin, RE:BERRY Gangnam follows conservative medical guidelines. Please inform your physician if you are pregnant, planning pregnancy, or breastfeeding.
Absolutely. RE:BERRY Gangnam welcomes international patients for cystic acne treatment with same-day or next-day appointments. Our 8-language support team (English, Japanese, Chinese, Thai, Vietnamese, Mongolian, Farsi, Korean) coordinates everything from booking to aftercare. We are 2 minutes from Gangnam Station Exit 10.
Post-cystic acne treatment skincare: (1) gentle cleanser only for first 3 days; (2) physician-provided recovery cream for first 5 days; (3) SPF 30+ daily mandatory; (4) no retinoids, AHA, BHA, or vitamin C serum for 7-10 days; (5) avoid saunas, swimming, and intense exercise for 72 hours. Consider adding Hydrafacial maintenance between sessions for gentle deep cleansing.
Cystic acne treatment uses Potenza RF at maximum depth (2.5-3.5mm versus 0.5-1.5mm for surface acne), higher RF energy settings, and often includes pre-treatment cyst decompression. The Signature Package components are the same, but the physician calibrates each device setting specifically for deep cystic pathology rather than superficial inflammatory lesions.
Potenza RF structurally modifies sebaceous glands through thermal coagulation, providing longer-lasting control than medications alone. However, hormonal fluctuations and genetic predisposition mean some patients may develop new cysts over time. Quarterly maintenance sessions reduce recurrence risk to approximately 15-20% at 12 months.
Yes, after the acute cystic phase resolves (typically 2-3 sessions), complementary procedures can enhance results. Acne scar treatment with subcision addresses residual atrophic scars. Pore tightening refines skin texture. These are typically introduced in sessions 3-4 of the cystic acne treatment course.
RE:BERRY Gangnam treats cystic acne patients aged 16 and older (parental consent required under 18). Cystic acne most commonly affects ages 15-35, but adult-onset cystic acne (particularly hormonal patterns in women 25-45) represents approximately 40% of our cystic acne treatment cases.
Cystic acne treatment is classified as a non-covered medical service in Korea. It is not covered by Korean national health insurance or most international travel insurance plans. RE:BERRY Gangnam provides transparent published pricing: ₩490,000 base or ₩1,290,000 Signature Package per session.
Chemical peels like LHALA Peel (₩77,000) work at the epidermal level (0.1-0.3mm depth) and cannot reach cystic lesions at 2-5mm depth. Peels are useful for comedonal acne and maintenance but lack the depth penetration and sebaceous gland modification required for cystic acne treatment. RF microneedling is the appropriate modality.
Three differentiators: (1) physician-performed deep RF at 2.5-3.5mm by Dr. Yoon-Gon Ryu or Dr. Yejin Oh, never delegated to technicians; (2) integrated multi-device protocol combining RF, PDT, skin boosters, and ultrasound in a single comprehensive session; (3) a 14,000 sq ft facility with 30+ devices providing more treatment options than most clinics.
Yes, RE:BERRY Gangnam offers pre-visit video consultations where the physician can assess your cystic acne severity, discuss treatment options, estimate session count and cost, and create a preliminary plan before you travel to Seoul. Contact us via WhatsApp, LINE, KakaoTalk, or WeChat to schedule.
Korea’s competitive aesthetic medicine market, high patient volume, and MFDS-regulated device ecosystem produce 40-60% lower costs than equivalent treatments in the US, UK, or Australia.
