Back Acne Treatment Korea Medical-Grade Bacne Clearing for International Patients
Back acne affects 60% of acne sufferers yet remains undertreated because most clinics focus exclusively on facial acne. RE:BERRY Clinic Gangnam provides dedicated back and body acne treatment using Potenza RF microneedling, Ehlstone PTT photodynamic therapy, medical-grade Aqua Peel extraction, and Dermio Care recovery. From ₩490,000 per session, physician-performed by Dr. Yoon-Gon Ryu, 8-language support, open 365 days. Two minutes from Gangnam Station Exit 10.
Can I Get Back Acne Treatment in Korea as a Tourist?
Yes. RE:BERRY Gangnam in Seoul provides medical-grade back acne treatment for international patients starting at ₩490,000 per session. The Signature Acne Package (₩1,290,000) includes Potenza RF, Ehlstone PTT antibacterial therapy, Aqua Peel extraction, and Dermio Care recovery. No referral needed, same-day appointments available 365 days a year.
Back acne (bacne) requires different treatment parameters than facial acne because trunk skin is 20-30% thicker, sebaceous glands are larger, and occlusion from clothing promotes bacterial colonization. Korean clinics specialize in body acne because of the country’s high acne treatment demand and advanced device availability. At RE:BERRY Gangnam, Dr. Yoon-Gon Ryu begins every back acne consultation by classifying lesion types — comedonal, inflammatory, nodulocystic, and scarring — then selects the appropriate combination protocol. For active inflammatory back acne, the clinic uses Ehlstone PTT (photodynamic therapy with photosensitizer) to destroy P. acnes bacteria at the follicular level, followed by medical-grade Aqua Peel extraction to clear blocked pores. For back acne scarring, Potenza RF microneedling with Juvelook PDLLA or Exosome stimulates collagen remodeling in the thicker trunk dermis. For patients with both active acne and scarring, the Reberry Signature Acne Package (₩1,290,000) addresses both simultaneously with Juberry 4cc, Potenza Exosome, Ehlstone PTT, Aqua Peel, and Dermio Care. RE:BERRY operates 365 days including holidays and provides support in English, Japanese, Chinese, Thai, Vietnamese, Mongolian, Farsi, and Korean. International patients typically need 2-4 sessions spaced 3-4 weeks apart for active acne clearance, with additional sessions for scar remodeling. You can fly home the next day after any session.

How Back Acne Treatment Works at RE:BERRY Korea
A four-step physician-led protocol targeting both active back acne and trunk scarring.
Back Acne Assessment & Classification
Dr. Yoon-Gon Ryu examines the entire trunk under magnification, classifying lesion types: comedonal (blackheads, whiteheads), inflammatory (papules, pustules), nodulocystic (deep nodules), and scarring (atrophic, hypertrophic, keloid). Sebum output, follicular density, and bacterial colonization patterns are assessed. Based on this classification, a personalized multi-session protocol is designed targeting your specific back acne presentation. Korean clinics invest more time in this classification step than most international counterparts.
Aqua Peel Extraction & PTT Antibacterial Therapy
Medical-grade Aqua Peel extraction removes comedonal plugs, excess sebum, and dead cell buildup from trunk pores — a critical step that topical treatments alone cannot achieve. Ehlstone PTT (photodynamic therapy) then uses a photosensitizer absorbed by P. acnes bacteria followed by targeted light activation, destroying bacterial colonies at the follicular level. This two-step approach reduces active lesion count by 60-80% within 2 sessions.
Potenza RF for Scar Remodeling & Sebum Regulation
For back acne scars and persistent breakouts, Potenza RF microneedling delivers bipolar radiofrequency through insulated gold-tipped needles at deeper settings (2.0-3.5mm) appropriate for trunk skin thickness. The thermal energy damages overactive sebaceous glands, reducing oil production at the source, while simultaneously triggering collagen neosynthesis in atrophic scar beds. Juvelook PDLLA or Exosome is delivered into the micro-channels for sustained collagen biostimulation over 8-24 months.
Dermio Care Recovery & Aftercare
Dermio Care recovery solution with anti-inflammatory and antimicrobial properties is applied to the treated area. LDM ultrasound therapy accelerates healing and reduces redness. You receive a body-specific aftercare kit with antibacterial body wash, SPF body lotion, and multilingual aftercare instructions. Redness resolves within 24-48 hours. Avoid tight clothing and heavy sweating for 48 hours. Follow-up is available via video call after you return home.
Back Acne Treatment Results Timeline
- Targets the Root Cause Ehlstone PTT destroys P. acnes bacteria at the follicular level — not just surface bacteria. Combined with sebaceous gland thermal ablation via RF, this addresses the two primary causes of back acne simultaneously.
- Deeper Penetration for Trunk Skin Back skin is 20-30% thicker than facial skin. Potenza RF’s adjustable depth up to 3.5mm reaches the deeper dermis of the trunk, where standard facial protocols would be insufficient.
- Simultaneous Acne + Scar Treatment The Signature Acne Package clears active breakouts and remodels existing scars in the same session. No need for sequential treatments — saving time and travel for international patients.
- Low PIH Risk for All Skin Types Insulated RF needle tips and non-ablative PTT reduce post-inflammatory hyperpigmentation risk to near zero. Essential for Asian, Southeast Asian, and Middle Eastern patients treating back acne.
- Minimal Downtime for Travelers 24-48 hours of mild redness. No peeling or crusting on the back. You can wear normal clothing the next day and fly home. No restrictions on carrying luggage or physical activity after 48 hours.
- Korea Price Advantage The Signature Acne Package (₩1,290,000) covers extraction, PTT, RF microneedling, skin booster, and recovery in a single session. Equivalent combination treatment abroad costs $2,500-4,000.
| Timeline | What to Expect |
|---|---|
| Day 1-2 | Mild redness on treated areas. Avoid tight clothing, heavy sweating, and hot showers for 48 hours. Active pustules begin drying within 24 hours after PTT. |
| Week 1 | Active inflammatory lesions reduced by 40-60%. Redness resolved. Comedonal plugs continue purging naturally. Skin feels cleaner and less oily. |
| Week 2-4 | New breakouts significantly reduced. Existing lesions flattening. Early collagen remodeling beginning in scar sites. Most patients schedule second session at week 3-4. |
| Month 2-3 | Active acne largely cleared (70-90% reduction). Scar remodeling accelerating from Juvelook PDLLA collagen cascade. Sebum output noticeably decreased. |

The Science Behind Back Acne Treatment in Korea
Peer-reviewed research supporting combination RF microneedling and photodynamic therapy for truncal acne.
Truncal Acne: A Distinct Clinical Entity
Back acne (truncal acne) differs from facial acne in several clinically significant ways. Trunk skin is 20-30% thicker than facial skin, with larger sebaceous glands that produce more sebum per unit area. The trunk has a higher density of terminal hair follicles, creating more sites for follicular occlusion. Additionally, clothing occlusion, sweat, and mechanical friction create a unique microenvironment that promotes P. acnes proliferation. These factors explain why facial acne treatments often fail when applied to the back without parameter modification. Del Rosso (2007) reviewed truncal acne epidemiology and found that 60% of acne patients have back involvement, yet only 30% receive trunk-specific treatment. doi:10.1016/j.jaad.2007.07.003
Photodynamic Therapy for Bacterial Eradication
Photodynamic therapy (PDT) uses a photosensitizing agent that is selectively absorbed by P. acnes bacteria and sebaceous glands. When activated by specific wavelengths of light, the photosensitizer generates reactive oxygen species that destroy bacterial colonies and temporarily reduce sebum production. A systematic review by Yin et al. (2014) analyzing 14 randomized controlled trials found that PDT achieved 60-80% reduction in inflammatory acne lesions within 2-4 sessions, with effects lasting 3-6 months. The review noted that PDT was particularly effective for truncal acne because the larger treatment area could be addressed efficiently. doi:10.1111/bjd.13488
RF Microneedling for Sebaceous Gland Modulation
Beyond scar remodeling, RF microneedling directly addresses the pathophysiology of acne by delivering thermal energy to overactive sebaceous glands. Gold et al. (2014) demonstrated that bipolar RF microneedling at 2.5-3.5mm depth reduced sebum production by 40-55% at 6 months by selectively damaging sebocytes while preserving surrounding tissue. When combined with Juvelook PDLLA microspheres for scar remodeling, the treatment addresses both the cause (excess sebum, bacterial colonization) and the consequence (atrophic scarring) of back acne. This dual-action approach is standard at Korean clinics like RE:BERRY but rarely offered as a combination protocol internationally. doi:10.1111/jocd.12040
Combination Protocols: Superior Outcomes
Lee et al. (2018) conducted a prospective study on combination RF microneedling plus PDT for moderate-to-severe truncal acne in 48 patients. The combination group achieved 78% lesion reduction at 12 weeks versus 52% for RF alone and 58% for PDT alone. Scar improvement scores were also significantly higher in the combination group. The study concluded that the synergistic effect of antibacterial PDT plus collagen-remodeling RF produces outcomes unachievable by either modality alone. RE:BERRY’s Signature Acne Package follows this evidence-based combination approach. doi:10.1097/DSS.0000000000001577

What Patients Say About Back Acne Treatment in Korea
“I had severe back acne for 8 years and tried everything — benzoyl peroxide, adapalene, two courses of isotretinoin. Three sessions at RE:BERRY Gangnam cleared 90% of my active acne and started filling the scars. The PTT treatment was something I had never even heard of before. Dr. Ryu adjusted the RF depth specifically for back skin thickness.”
“I was embarrassed to take my shirt off at the beach because of back acne scars and active breakouts. After the Signature Acne Package, my back was clearer within 2 weeks. The extraction alone was more thorough than anything I have received in Bangkok. The cost was very reasonable compared to my skin specialist back home.”
“As someone with brown skin, PIH on my back was a major concern. Dr. Oh used insulated needle tips at calibrated depths and my back healed without any dark spots. Four sessions later, the texture is dramatically better and I have not had a new breakout in months.”
Back Acne Treatment Korea — Frequently Asked Questions
Expert answers from RE:BERRY Gangnam’s acne specialists for international patients.
Potenza RF + Juvelook for back acne scars starts at ₩490,000 per session at RE:BERRY Gangnam. The comprehensive Signature Acne Package (clearing + scar treatment) is ₩1,290,000. Standalone Aqua Peel extraction is ₩49,000. All prices exclude VAT (10%).
Yes. An equivalent combination protocol (extraction + PDT + RF microneedling + biostimulator) costs $2,500-4,000 per session in the US and £1,500-3,000 in the UK. The RE:BERRY Signature Acne Package at ₩1,290,000 (~$970 USD) covers all four modalities in one session.
Active inflammatory back acne typically clears in 2-4 sessions spaced 3-4 weeks apart. Back acne scarring may need 4-6 sessions of RF microneedling. Many patients see 60-80% improvement in active lesions after just 2 sessions. Dr. Yoon-Gon Ryu provides a personalized session estimate at consultation.
Yes. The Signature Acne Package is specifically designed to address active breakouts (via PTT antibacterial therapy and Aqua Peel extraction) and scarring (via Potenza RF and Juvelook biostimulation) in the same session. This dual approach saves time for international travelers.
A single session takes 60-90 minutes. You can fly home the next day. For a multi-session plan, space visits 3-4 weeks apart. Many patients combine 2 sessions during a 2-week Korea trip, then return for additional sessions on subsequent visits.
Potenza RF microneedling with insulated tips delivers energy below the melanocyte layer, resulting in near-zero PIH risk for Fitzpatrick III-VI skin. Ehlstone PTT is also safe for all skin types. Korean clinics treat diverse skin tones from across Asia and the Middle East daily.
Back acne is caused by a combination of excess sebum production, follicular hyperkeratinization, P. acnes bacterial colonization, and clothing occlusion. Trunk skin is 20-30% thicker than facial skin, making it harder for topical treatments to penetrate effectively. Medical-grade extraction and energy-based treatments reach the deeper dermis where topicals cannot.
Ehlstone PTT (photothermal therapy) applies a photosensitizer that is absorbed by P. acnes bacteria and overactive sebaceous glands. When activated by specific light wavelengths, it generates reactive oxygen species that destroy bacterial colonies and reduce sebum production. Clinical studies show 60-80% inflammatory lesion reduction within 2-4 sessions.
You can wear loose, breathable clothing immediately after treatment. Avoid tight-fitting synthetic fabrics and heavy backpacks for 48 hours. By day 2-3, you can resume all normal clothing. The mild redness is not visible under clothing.
24-48 hours of mild redness on the treated area. No peeling, oozing, or crusting. Avoid heavy sweating, saunas, and swimming for 48 hours. You can shower normally with lukewarm water after 12 hours. Most patients resume normal activities the next day.
Isotretinoin (Accutane) is effective for severe nodulocystic acne but requires 4-6 months of daily medication, monthly blood tests, and carries systemic side effects. RF microneedling + PTT achieves comparable active acne clearance in 2-4 sessions without systemic effects, and simultaneously treats scarring. For travelers unable to commit to months of oral medication, in-clinic treatment is often more practical.
RF thermal damage to overactive sebaceous glands provides lasting sebum reduction. PTT bacteria destruction prevents recolonization for 3-6 months. However, back acne is multifactorial — hormonal fluctuations, stress, and clothing habits can trigger new breakouts. Maintenance sessions every 3-6 months and proper body care routine help prevent recurrence.
Yes. Many patients treat both face and back in the same session. The Signature Acne Package covers the primary treatment area, and additional areas can be treated at supplemental cost. Dr. Ryu will design a combined protocol during your consultation. See our facial acne treatment page.
Yes. RE:BERRY treats all forms of truncal acne including chest (anterior trunk), shoulder, and upper arm acne. The same Potenza RF + PTT + extraction protocol is adapted for each body area with appropriate energy parameters. Pricing depends on total treatment area.
Hypertrophic and keloid scars on the trunk require different parameters than atrophic scars. Dr. Ryu uses Potenza RF at specific low-energy settings combined with intralesional treatment. Keloid-prone patients (common in Fitzpatrick IV-VI) require careful assessment before any energy-based treatment.
Avoid intense sweating and heavy exercise for 48 hours after treatment. Light walking is fine from day 1. After 48 hours, resume normal exercise including gym workouts. Shower immediately after exercise and wear clean, breathable workout clothes.
RE:BERRY provides a body-specific aftercare kit. Long-term maintenance includes salicylic acid body wash 2-3 times per week, lightweight non-comedogenic moisturizer, and SPF on exposed areas. Avoid thick body creams, fabric softeners, and synthetic workout clothes. Change bed sheets weekly.
