Side Effects of Skin Treatment in Myeongdong Seoul — Complete Safety Guide 2026
Understanding the side effects of skin treatment is essential before visiting any aesthetic clinic in Seoul. RE:BERRY Myeongdong provides transparent information on every possible reaction — from mild redness after laser toning to rare complications from injectable procedures. Our licensed physicians perform over 30,000 treatments annually using 30+ KFDA-approved devices, ensuring that side effects are minimized through proper technique, genuine products, and personalized protocols.
What Are the Common Side Effects of Skin Treatment at RE:BERRY Myeongdong?
Over 90% of skin treatments at RE:BERRY Myeongdong cause only mild, temporary side effects — redness lasting 1-4 hours after laser procedures, minor swelling for 24-48 hours after injectables, and slight tenderness after RF treatments like Potenza (₩249,000 first visit). Serious complications occur in fewer than 0.5% of cases when performed by licensed physicians using KFDA-approved devices.
Side effects of skin treatment vary dramatically depending on the procedure type, the device used, and the skill of the performing physician. At RE:BERRY Myeongdong, Dr. Seung-Jae Baek and Dr. Hoon-Sung Son classify side effects into three categories: expected effects (redness, warmth, mild swelling that resolve within hours), common side effects (bruising, temporary sensitivity lasting 1-7 days), and rare complications (infection, scarring, pigmentation changes occurring in fewer than 1% of cases). Non-invasive treatments like glass skin laser toning and Aqua Peel carry virtually zero risk of serious side effects. Minimally invasive procedures such as Botox and dermal fillers carry slightly higher risk profiles but remain extremely safe when performed by experienced physicians. The key factor in minimizing side effects is choosing a clinic that uses genuine, KFDA-approved devices and employs licensed medical professionals — not aestheticians — for all procedures.

How RE:BERRY Myeongdong Minimizes Side Effects of Skin Treatment
Our four-step safety protocol ensures side effects of skin treatment are kept to an absolute minimum for every patient.
Pre-Treatment Skin Assessment & Medical History
Dr. Seung-Jae Baek begins every consultation with a comprehensive skin assessment using Fitzpatrick typing and medical history review. This includes checking for allergies, current medications (especially blood thinners, retinoids, and immunosuppressants), prior adverse reactions to skin treatments, and any active infections or skin conditions. Patients on isotretinoin must wait 6 months before laser procedures. This screening alone prevents 80% of avoidable side effects of skin treatment at RE:BERRY Myeongdong. The consultation is available in 8 languages through our multilingual coordination team.
Device Calibration & Parameter Selection
Every KFDA-approved device at RE:BERRY Myeongdong is calibrated to the patient’s specific skin type, condition, and tolerance level. For laser treatments, this means adjusting wavelength, pulse duration, fluence, and spot size. For RF devices like Potenza, needle depth and RF energy are customized per zone. For injectables like Rejuran and Juvelook, injection depth and volume are tailored to each facial area. Over-aggressive settings are the primary cause of preventable side effects — our physicians use conservative-to-moderate parameters for first treatments.
Treatment Execution by Licensed Physician
All procedures at RE:BERRY Myeongdong are performed by Dr. Seung-Jae Baek (License #143338) or Dr. Hoon-Sung Son (License #125783) — never by nurses or aestheticians. Physician-performed procedures have significantly lower complication rates because doctors can recognize and respond to unexpected skin reactions in real time. During Thermage FLX treatments, for example, Dr. Baek monitors tissue impedance changes to prevent thermal injury. During filler injections, aspiration technique confirms needle placement away from blood vessels.
Post-Treatment Monitoring & Aftercare Protocol
After every procedure, patients remain at RE:BERRY Myeongdong for 10-15 minutes of observation. A soothing mask, LED therapy, or Dermio Care session calms the skin and reduces initial redness. You receive a printed aftercare guide in your language with emergency contact numbers, expected vs. concerning symptoms, product recommendations (SPF 50+, gentle cleanser), and activity restrictions. For injectable procedures, a 48-hour follow-up via WhatsApp or LINE ensures any developing side effects are caught early.
Side Effects of Skin Treatment — Recovery Timeline at RE:BERRY Myeongdong
- Laser Treatments (PicoSure, Genesis, Pico Fraxel): Redness 1-4 hours. No downtime for toning lasers. Fraxel may cause micro-crusting for 3-5 days. SPF 50+ required for 2 weeks.
- RF Devices (Potenza, Thermage, Sofwave): Mild swelling 24-48 hours. Warmth for 2-4 hours. Rare bruising resolves in 5-7 days. No open wounds.
- Injectables (Botox, Fillers, Skin Boosters): Pinpoint bruising at injection sites resolves in 3-7 days. Swelling peaks at 24 hours, subsides by day 3. Avoid alcohol 24 hours pre and post.
- HIFU Devices (Ultherapy, Sofwave, Shurink): Tenderness to touch for 1-2 weeks. Mild numbness in treated areas for 2-4 weeks. No visible external side effects.
- Combination Packages: When combining multiple treatments in one session, side effects of skin treatment are cumulative — expect slightly more redness and swelling than single procedures.
| Timeline | What to Expect |
|---|---|
| 0-4 Hours Post | Redness, warmth, and mild tingling. These are normal inflammatory responses to controlled tissue stimulation. |
| Day 1-2 | Swelling peaks for injectable treatments. Laser-treated skin may feel tight. Apply prescribed moisturizer. |
| Day 3-5 | Most side effects resolve. Fraxel micro-crusts shed naturally. Bruise spots start fading. |
| Week 1-2 | Skin normalizes completely. Collagen remodeling begins beneath the surface. Safe to resume all activities. |
| Week 3-4 | Treatment benefits emerge visibly. Any post-inflammatory pigmentation (rare) begins resolving. |
| Month 2-3 | Full results visible. Any lingering sensitivity completely gone. Safe to repeat treatment. |

The Science of Side Effects of Skin Treatment
Peer-reviewed research on the safety profiles of aesthetic treatments offered at RE:BERRY Myeongdong.
Laser Treatment Side Effects: Incidence and Severity
Non-ablative laser treatments — including picosecond and Nd:YAG toning used at RE:BERRY Myeongdong — demonstrate exceptionally low side effect profiles. A large-scale retrospective analysis of 1,000 patients receiving picosecond laser treatments found that 95.6% experienced only transient erythema lasting less than 24 hours, with no cases of scarring or permanent pigmentation changes. The key safety advantage of picosecond technology over traditional Q-switched nanosecond lasers is the photomechanical rather than photothermal mechanism — generating pressure waves rather than sustained heat, which dramatically reduces thermal injury to surrounding tissue. For Asian skin types (Fitzpatrick III-V), which constitute the majority of patients at RE:BERRY Myeongdong, post-inflammatory hyperpigmentation (PIH) remains the primary concern with laser treatments. However, modern wavelength-specific protocols and conservative fluence settings have reduced PIH incidence to below 2% in experienced hands.
Radiofrequency Microneedling Safety Profile
Radiofrequency microneedling devices like Potenza combine physical needle penetration with controlled RF energy delivery. The side effects of skin treatment with RF microneedling are primarily related to the mechanical component — pinpoint bleeding, erythema, and edema that typically resolve within 48 hours. A prospective study of 120 patients receiving bipolar fractional RF microneedling reported side effects limited to erythema (100%, resolved within 48 hours), mild edema (67%, resolved within 24 hours), and pinpoint crusting (23%, resolved within 72 hours). No instances of scarring, infection, or persistent pigmentation changes were recorded. The insulated needle tip design used in devices at RE:BERRY Myeongdong protects the epidermis while delivering RF energy precisely to the target dermis depth, further reducing surface-level side effects compared to non-insulated designs.
Injectable Complications: Prevention Through Technique
Injectable treatments including neurotoxins (Botox, Xeomin) and dermal fillers (Juvederm, Belotero) carry the highest side effect potential among non-surgical aesthetic procedures, though serious complications remain rare. The most common side effects — injection-site bruising (10-20%), swelling (15-30%), and tenderness (20-40%) — are self-limiting and resolve within 7-14 days. Serious complications including vascular occlusion, tissue necrosis, and vision loss occur at rates below 0.05% in published literature and are almost exclusively technique-dependent rather than product-dependent. At RE:BERRY Myeongdong, all injectable procedures are performed by licensed physicians using aspiration technique, anatomical landmark protocols, and hyaluronidase emergency kits on hand. Cannula-based injection techniques for high-risk zones (nasolabial folds, glabella, nose) further reduce vascular complication risk by 85% compared to sharp needle approaches.

What Patients Say About Side Effects of Skin Treatment at RE:BERRY Myeongdong
“I was terrified about skin treatment side effects after reading horror stories online. Dr. Baek spent 20 minutes explaining exactly what to expect from Potenza — redness for 2 days, mild swelling overnight. That is exactly what happened. Nothing more, nothing less. The transparency was incredibly reassuring.”
“Had Dual Toning laser at 11am, went shopping in Myeongdong by noon. Zero side effects. My friend had the same treatment at another clinic and had redness for 2 days — I think RE:BERRY’s device settings are more conservative and safer. Will come back for the full 5-session course.”
“Got Juvederm lip filler and was warned about 3-5 days of swelling. Swelling was noticeable for exactly 3 days, then perfect. Dr. Son checked on me via WhatsApp the next day. This level of aftercare is why I travel from Bangkok to Seoul for treatments.”
