What Do Laser Treatment Results Look Like Before and After in Korea?
At RE:BERRY Gangnam, every laser treatment before and after photo follows a strict clinical documentation protocol. We label each result with the patient's Fitzpatrick skin type, the number of sessions completed, the device used, and the time elapsed between photos. This level of detail allows prospective patients — including international medical tourists visiting Seoul — to find cases that closely match their own skin type and concerns.
Our gallery includes results from Pico Laser, Laser Toning, Acne Scar Laser, IPL Therapy, Dark Spot Laser Treatment, Carbon Laser Peel, and Skin Brightening Laser procedures — all performed by Medical Director Dr. Yoon-Gon Ryu.
How We Document Your Laser Treatment Results
Our documentation process eliminates lighting tricks, angle manipulation, and digital retouching.
Pre-Treatment Photography
Baseline images captured under fixed clinical lighting with calibrated white balance, consistent camera distance and angle, and dermatoscope assessment. Your Fitzpatrick skin type is recorded. This ensures every "before" image is a true scientific baseline.
Treatment Protocol Logging
Every parameter is recorded: device, wavelength, fluence, pulse duration, spot size, and passes. When our gallery shows "3 sessions, PicoSure 755nm, Fitzpatrick IV," that data comes from clinical records — not estimates.
Post-Treatment Follow-Up Photography
Results are photographed under identical conditions to baseline: same lighting, angle, and camera settings. Follow-up images at 2 weeks, 1 month, and 3 months ensure the visible difference reflects genuine tissue change.
Result Verification and Publication
Dr. Yoon-Gon Ryu personally reviews and approves every entry before publication. No retouching, no filters, no AI enhancement. Patient consent obtained via PF-6 protocol.
When to Expect Results From Each Laser Treatment
One of the most common questions from patients visiting our Gangnam clinic is: "How soon will I see results?" The timeline depends on the treatment type, the severity of your condition, your Fitzpatrick skin type, and how closely you follow aftercare instructions — particularly sun protection.
Below is a summary of expected timelines based on our clinical experience and peer-reviewed evidence:
| Treatment | Initial Results | Optimal Results | How Long Results Last |
|---|---|---|---|
| Pico Laser (Pigmentation) | After 1–2 sessions | 3–5 sessions | 1–3 years with sun protection |
| Laser Toning (Melasma) | After 3–4 sessions | 5–10 weekly sessions | Maintenance every 1–3 months |
| Acne Scar Laser (Fractional) | After 2–3 sessions | 3–6 sessions (4–6 week intervals) | Collagen remodeling largely permanent (2+ years) |
| IPL Therapy | After 2–3 sessions | 3–5 sessions | 6–12 months, maintenance recommended |
| Dark Spot Removal | After 1–2 sessions | 2–4 sessions | 1–3 years with SPF compliance |
| Carbon Laser Peel | Immediate glow after 1 session | 3–5 sessions for pore/texture | Monthly maintenance recommended |
Results are cumulative. Each session builds on the last. Dr. Yoon-Gon Ryu customizes treatment intervals based on your skin's response at each follow-up assessment.
Real Patient Results Gallery
Individual results may vary. All photos are unretouched and taken under standardized clinical conditions. No AI-generated or stock images are used.
Dark Spot and Pigmentation Removal Results
These results showcase Pico Laser and Dark Spot Laser Treatment outcomes for sun spots, age spots, freckles, and post-inflammatory hyperpigmentation. Each entry includes the patient's Fitzpatrick type and the number of sessions completed.
Acne Scar Treatment Results
These results demonstrate Acne Scar Laser treatment outcomes using fractional laser technology. Acne scarring responds to collagen remodeling stimulated by controlled micro-injuries to the dermal layer.
Laser Treatment Results Compared — Which Treatment Is Right for You?
Not all laser treatments produce the same type of result. The comparison below helps you understand which modality addresses your specific concern, how many sessions to expect, and what level of improvement is realistic based on clinical evidence.
| Treatment | Best For | Sessions | Expected Improvement | Downtime | Skin Types |
|---|---|---|---|---|---|
| Pico Laser | Sun spots, age spots, freckles, tattoo ink | 3–5 | 50–80% pigment clearance | 1–3 days (mild redness) | Fitzpatrick I–V |
| Laser Toning | Melasma, overall skin tone evening | 5–10 (weekly) | 40–70% improvement (gradual) | None — same-day return | Fitzpatrick III–V (optimized for Asian skin) |
| Fractional CO2/Er:YAG | Ice pick scars, boxcar scars, rolling scars | 3–6 (4–6 week intervals) | 40–70% scar depth reduction | 5–10 days (crusting, redness) | Fitzpatrick I–IV (caution V–VI) |
| IPL Therapy | Redness, rosacea, mild pigmentation, sun damage | 3–5 | 30–60% improvement | 1–3 days (mild swelling) | Fitzpatrick I–III (limited for darker skin) |
| Carbon Laser Peel | Enlarged pores, oily skin, superficial texture | 3–5 (monthly) | Pore size reduction, smoother texture | None — "lunchtime procedure" | Fitzpatrick I–V |
Why this matters: RE:BERRY Gangnam uses only FDA-cleared and CE-marked devices — including the PicoSure (FDA 510(k) K161222) and PicoWay (FDA 510(k) K142363) picosecond lasers. During your free consultation, Dr. Yoon-Gon Ryu evaluates your Fitzpatrick type, condition severity, and timeline to recommend the optimal laser or combination for your case. The before-and-after results in our gallery reflect this individualized, evidence-based approach.

A Note From Dr. Yoon-Gon Ryu on Interpreting Before and After Results
Dr. Yoon-Gon Ryu
CEO / Medical Director, Medical Director (피부과전문의)
KMA Registration No. 제 89804 호 · 12,000+ laser procedures over 15 years
"Having performed over 12,000 laser procedures at our Gangnam clinic, I want every patient — from Seoul or abroad — to understand what before-and-after photos can and cannot tell you.
Standardized photography matters: Many clinics use different lighting, angles, or settings between photos. At RE:BERRY, every image uses identical conditions. The difference you see is real tissue change, not a photography trick.
Individual results vary: Your outcome depends on Fitzpatrick type, condition severity, aftercare compliance (especially SPF), and sessions completed. A Fitzpatrick III patient with recent sun spots may clear in 2 sessions, while chronic melasma in Fitzpatrick V skin may require 8–10 sessions of laser toning.
Cumulative improvement: Most laser treatments build results across sessions. The 'after' photo represents a complete treatment course, not a single visit.
Fitzpatrick labeling: We label every photo so you can find results from patients with similar skin. A Fitzpatrick II pico laser result differs from Fitzpatrick V — both excellent, but timelines differ.
Book a consultation and I will personally review your skin and show you relevant cases."
The Science Behind Measuring Laser Treatment Results
Objectively measuring "improvement" in laser treatment before and after results requires validated clinical scoring systems rather than subjective visual assessment alone. At RE:BERRY Gangnam, Dr. Yoon-Gon Ryu applies peer-reviewed measurement frameworks to every patient's treatment course, ensuring outcomes are quantifiable, reproducible, and comparable across cases.
MASI Scoring for Melasma Assessment
The Melasma Area and Severity Index (MASI) quantifies melasma severity across four facial regions based on area, darkness, and homogeneity (scores 0–48). In clinical trials of low-fluence Q-switched Nd:YAG laser toning, MASI scores decreased 30–60% after 5–10 sessions. Jeong et al. (2010) demonstrated significant MASI reduction in Korean patients with refractory melasma using low-fluence 1,064nm Nd:YAG combined with topical therapy (Dermatologic Surgery, 2010; DOI: 10.1111/j.1524-4725.2010.01523.x). Wattanakrai et al. (2010) confirmed similar results in Fitzpatrick III–V Asian skin (Dermatologic Surgery, 2010).
Goodman and Baron Scale for Acne Scar Grading
The Goodman and Baron scale grades acne scars from 1 (macular) to 4 (severe/hyperplastic), scoring ice pick, rolling, boxcar, and hypertrophic scars by count and severity. Fractional laser treatment typically moves patients down 1–2 grades after 3–6 sessions.
Melanin Index and Spectrophotometry
Reflectance spectrophotometry measures the melanin index after pico laser treatment, separating melanin from hemoglobin for objective pigment tracking. Kung et al. (2019) confirmed dual-wavelength picosecond laser achieved significant pigment clearance in Fitzpatrick III–V patients with benign pigmented lesions (Lasers in Surgery and Medicine, 2019).
Picosecond vs. Nanosecond Mechanisms
Picosecond pulses (10⁻¹² seconds) generate photomechanical disruption rather than photothermal damage, shattering pigment into smaller fragments cleared more efficiently by macrophages. This produces faster clearance with fewer sessions. Bernstein et al. (2015) demonstrated this photomechanical superiority using dual-wavelength Nd:YAG picosecond laser (Lasers in Surgery and Medicine, 2015; PMID: 25899947).
Low-Fluence 1064nm for Melasma
Laser toning achieves subcellular melanosome destruction without rupturing melanocytes, avoiding rebound hyperpigmentation. Chalermchai and Rummaneethorn (2018) confirmed fractional picosecond 1,064nm laser improved both dermal and mixed-type melasma with minimal side effects (Journal of Cosmetic and Laser Therapy, 2018; DOI: 10.1080/14764172.2017.1376099).
Patient-Reported Outcomes
Patient satisfaction surveys (PROMs) report 70–90% satisfaction following complete pico laser and laser toning courses, correlated to sessions completed and sun protection adherence.
What Our Patients Say About Their Results
"I had dark spots on both cheeks for years. After 4 sessions of pico laser at RE:BERRY Gangnam, about 80% of the pigmentation is gone. Dr. Ryu showed me my Fitzpatrick type IV results from other patients during consultation, which gave me realistic expectations. The improvement matched what he predicted."
S.T. · Japan · Pico Laser, 4 sessions
"I traveled from Bangkok specifically for laser toning. My melasma had been resistant to everything I tried in Thailand. After 8 sessions with Dr. Yoon-Gon Ryu, my MASI score dropped significantly. The results were gradual but clearly visible by session 5. I continue maintenance every 2 months."
P.K. · Thailand · Laser Toning, 8 sessions
"The acne scars from my teenage years made me self-conscious for over a decade. Five sessions of fractional laser at RE:BERRY transformed my skin texture. The before-and-after photos from my chart are dramatic — I almost didn't recognize my own skin. Dr. Ryu was thorough and honest about the timeline from day one."
M.H. · United States · Acne Scar Laser, 5 sessions
"As someone with Fitzpatrick V skin, I was nervous about laser treatment causing hyperpigmentation. Dr. Ryu adjusted the protocol specifically for my skin type — lower energy, more sessions. After 5 sessions of pico laser, my sun spots cleared beautifully with zero PIH. I wish I had done this years ago."

Frequently Asked Questions About Before and After Results
Yes. All laser treatment before and after photos at RE:BERRY Gangnam are taken under standardized clinical lighting with consistent camera settings. No AI generation, no digital retouching, no stock images. Every photo is verified and approved by Dr. Yoon-Gon Ryu before publication.
Session counts vary by treatment: pico laser typically requires 3–5 sessions for pigmentation, laser toning needs 5–10 weekly sessions for melasma, and acne scar laser takes 3–6 sessions at 4–6 week intervals. Individual factors including Fitzpatrick type and condition severity affect your specific timeline.
Results vary based on your Fitzpatrick skin type, the severity and chronicity of your condition, your aftercare compliance (especially sun protection), and the number of sessions completed. Our photos show typical outcomes — a free consultation with Dr. Yoon-Gon Ryu provides personalized expectations based on your skin profile.
The Fitzpatrick scale classifies skin types I through VI based on how skin responds to UV exposure. It determines optimal laser settings, expected outcomes, and risk profile for each patient. RE:BERRY labels every before-and-after photo with the patient's Fitzpatrick type so you can find results from people with skin similar to yours.
Longevity depends on the condition treated. Pigmentation from sun damage: 1–3 years with consistent SPF use. Melasma: requires maintenance every 1–3 months as it is chronic. Acne scar improvement: collagen remodeling results are largely permanent, lasting 2+ years. Diligent sun protection extends all results.
Our gallery is organized by treatment category with anchor links. Browse by your specific concern — dark spots, acne scars, melasma — or book a free consultation where Dr. Ryu can show you relevant cases from our clinical records matching your skin type and condition.
Dr. Yoon-Gon Ryu conducts follow-up assessments after every treatment course. If results fall short of expectations, your plan is adjusted — additional sessions, alternative laser modalities, or combination approaches may be recommended. Patient satisfaction is tracked and addressed at every stage.
We follow a standardized clinical photography protocol: fixed lighting setup, calibrated white balance, consistent camera distance and angle, and identical settings for both the "before" and "after" images. No filters are applied. This ensures the visual difference reflects real tissue change only.
Yes — treatment protocols are optimized per Fitzpatrick type. Asian skin (Fitzpatrick III–V) uses adjusted energy settings to minimize post-inflammatory hyperpigmentation risk while maintaining efficacy. Our gallery includes results across multiple Fitzpatrick types so patients of all backgrounds can find relevant examples.
