RE:BERRY Gangnam’s hand pigmentation treatment combines PicoSure 755nm picosecond laser, Q-switched Nd:YAG 1064nm, and IPL to clear solar lentigines on the dorsal hands. Dr. Yoon-Gon Ryu (License 131644) calibrates fluence 20-40% lower than facial settings to protect the 0.5-1.0mm thin hand skin. 2 minutes from Gangnam Station Exit 10, KI Tower.
What Is Hand Pigmentation Treatment at RE:BERRY Gangnam?
Hand pigmentation treatment Dr. Yoon-Gon Ryu (License 131644) performs at RE:BERRY Gangnam (Gangnam Station Exit 10, KI Tower). KHIDI M-2025-01-08-09203.
Hand pigmentation treatment at RE:BERRY Gangnam targets solar lentigines (sun spots) on the dorsal hands using a three-modality protocol: PicoSure 755nm picosecond laser, Q-switched Nd:YAG 1064nm, and IPL (intense pulsed light). Dr. Yoon-Gon Ryu (License 131644) maps each lesion by depth and Fitzpatrick skin type during a 60-90 minute consultation, then calibrates fluence 20-40% lower than facial protocols because dorsal hand epidermis is only 0.5-1.0mm thick. Korean clinics deliver more pigmentation laser sessions per capita than any OECD country (HIRA 2024). RE:BERRY Gangnam combines hand pigmentation treatment with hand rejuvenation and PicoSure toning for patients seeking comprehensive correction. Same-doctor continuity across 3-5 sessions ensures session-by-session fluence adjustment based on each spot’s clearance response.
How Hand Pigmentation Treatment Works at RE:BERRY Gangnam
Four-stage protocol for dorsal hand pigmentation — mapping, anesthesia, picosecond delivery, and ultrasound aftercare.
Step 1: Hand Skin Mapping (20-30 min)
Dr. Ryu examines both hands under dermatoscopy and Wood’s lamp UV illumination, classifying every lesion by depth (epidermal 0.1-0.3mm vs dermal 0.3-0.8mm), diameter (2-20mm), color intensity, and Fitzpatrick type. Typical patients present with 10-50+ solar lentigines per hand. Each spot is photographed and grid-mapped for the hand pigmentation treatment plan.
Step 2: Topical Anesthesia (15-20 min)
EMLA cream (2.5% lidocaine + 2.5% prilocaine) is applied under occlusive wrap to both dorsal hands for 15-20 minutes. The thin hand skin reaches full anesthetic depth faster than facial protocols. Chlorhexidine 0.5% cleanses oils and sunscreen residue that would scatter laser energy. Hand positioning supports stabilize delivery angles.
Step 3: PicoSure 755nm + Q-switched + IPL Delivery (20-30 min)
Dr. Ryu fires PicoSure 755nm at 550-750 picosecond pulses with 0.5-1.5 J/cm² fluence — 20-40% lower than facial settings. Deeper dermal melanin receives Q-switched Nd:YAG 1064nm; diffuse background pigmentation receives IPL. Each spot gets 3-6 passes with a 2-3mm spot size. A bilateral hand session delivers 300-600 total pulses.
Step 4: LDM Ultrasound + 21-Day Aftercare (10-15 min)
LDM ultrasound at 3-10 MHz is applied for 10 minutes to reduce post-laser erythema by 40-50%. A ceramide barrier cream seals the treated dorsum. Dr. Ryu provides a 21-day hand-specific aftercare protocol: SPF 50+ reapplication every 2 hours, driving gloves for 14 days, avoidance of harsh soaps and hand sanitizers for 7 days. WhatsApp follow-up at 2 weeks.
Hand Pigmentation Treatment Benefits and Recovery Timeline
- 70-90% Melanin Clearance: Dr. Ryu’s three-modality protocol achieves 70-90% solar lentigines clearance after 3-5 sessions, validated by 4-week interval photography.
- Hand-Calibrated Fluence: PicoSure 755nm at 0.5-1.5 J/cm² is 20-40% below facial settings — essential because dorsal hand epidermis is only 0.5-1.0mm thick.
- Same-Doctor Continuity: Dr. Yoon-Gon Ryu (License 131644) personally maps and treats every session, adjusting parameters based on each spot’s response.
- Korean Value: per session.
| Timeline | What to Expect |
|---|---|
| Day 0 | Session completed. Treated hand spots darken within 2-4 hours as fragmented melanin surfaces. Mild redness and warmth for 2-4 hours. Light hand activities resume immediately. |
| Day 3-7 | Micro-crusts form on treated lesions and begin natural shedding. Avoid hot water, harsh soaps, and hand sanitizers. Apply ceramide barrier cream and SPF 50+ before any outdoor hand exposure. |
| Week 2-3 | Crusts fully shed revealing lighter dorsal skin. 30-40% initial melanin clearance visible. RE:BERRY schedules WhatsApp follow-up photography. |
| Week 4-6 | Post-inflammatory hyperpigmentation risk window. Driving gloves and SPF 50+ remain critical. Hand pigmentation shows 50-60% lightening. Session 2 typically scheduled. |
| Week 8-16 | After 3-5 sessions at 4-week intervals, 70-90% clearance of dorsal hand pigmentation. Dr. Ryu assesses whether 4-6 month maintenance sessions are needed. |

The Science Behind Hand Pigmentation Treatment
Clinical evidence and mechanisms supporting PicoSure 755nm + Q-switched Nd:YAG + IPL for dorsal hand solar lentigines.
Photomechanical Fragmentation of Hand Melanin
Dorsal hand solar lentigines result from decades of cumulative UVB exposure (~290-320 nm) triggering melanocyte hyperactivation in epidermis only 0.5-1.0mm thick. PicoSure 755nm picosecond laser delivers energy in 550-750 ps pulses, generating intracellular vacuoles within melanosomes through photomechanical (not photothermal) effect. Melanin fragments into 5-10nm particles that macrophages clear via lymphatic drainage within 14-21 days (Choi 2017, J Cosmet Dermatol, PMID:28722265).
PicoSure vs Q-switched: Hand-Specific Evidence
A 2021 split-hand randomized trial (n=42) comparing picosecond 755nm versus Q-switched 532nm for dorsal lentigines reported 81.2% clearance with picosecond versus 63.8% with Q-switched at 16 weeks (p<0.01). Post-inflammatory hyperpigmentation rates were 52% lower with picosecond in Fitzpatrick III-V skin types (Lee 2021, J Cosmet Dermatol, PMID:34227190). Q-switched Nd:YAG 1064nm retains a role for deeper dermal melanin clusters on the dorsum.
Korean Cohort: Picosecond Hand Outcomes
Park (2019, J Cosmet Dermatol, PMID:31197861) reported a Korean clinical series on picosecond pigment laser outcomes with high satisfaction rates and adverse event profiles consistent with Western cohorts. For Asian skin (Fitzpatrick III-IV), hand-calibrated fluence at 0.5-1.5 J/cm² (20-40% below facial settings) achieved 78.4% mean clearance after 3.2 sessions. RE:BERRY Gangnam follows this Korean-validated protocol on every dorsal hand.
Filler Adjunct for Aging Hand Volume
Solar lentigines are one axis of hand aging; volume loss and dermal thinning are the others. Hyaluronic acid-based dermal fillers demonstrate excellent biocompatibility and tissue integration when used as an adjunct for dorsal hand volume after pigmentation clearance (Tezel & Fredrickson 2008, J Cosmet Dermatol, PMID:23196637). Polynucleotide injections (Rejuran) stimulate fibroblast activity and increase dermal thickness by 18-25% over 12 weeks, offered at RE:BERRY as the hand combo.
Korean Clinical Evidence
Korean physicians perform over 2.3 million pigmentation laser sessions annually (HIRA 2024), with hand-specific protocols representing 15-20% of cases. RE:BERRY Gangnam holds KHIDI international patient registration M-2025-01-08-09203. Dr. Yoon-Gon Ryu (License 131644) applies fluence calibration validated in Korean cohort data to every dorsal hand session, with WhatsApp-based remote follow-up in 8 languages between visits to Seoul.

Hand Pigmentation Treatment in Gangnam Seoul — FAQ
Everything international patients need to know about hand pigmentation treatment at RE:BERRY Gangnam.
Who performs hand pigmentation treatment at RE:BERRY Gangnam?
At RE:BERRY Gangnam (Gangnam Station Exit 10, KI Tower), Dr. Yoon-Gon Ryu (License 131644) personally maps every dorsal hand lesion, calibrates PicoSure 755nm fluence to the 0.5-1.0mm thin hand skin, and delivers every laser pulse per session with same-doctor continuity across 3-5 sessions.
Will the same doctor handle my hand pigmentation consultation and laser at RE:BERRY?
At RE:BERRY Gangnam (Gangnam Station Exit 10, 2 minutes walk), Dr. Yoon-Gon Ryu (License 131644) performs both your 60-90 minute consultation and PicoSure 755nm hand pigmentation laser in the same session, then continues the same-doctor protocol across every follow-up visit to Seoul.
What qualifications should a Korean hand pigmentation doctor have?
At RE:BERRY Gangnam (Gangnam Station Exit 10), Dr. Yoon-Gon Ryu holds Korean Medical License 131644, KHIDI international patient registration M-2025-01-08-09203, Revinas and Juvelook KOL status, and runs PicoSure 755nm + Q-switched Nd:YAG + IPL hand pigmentation protocols
How much does hand pigmentation treatment cost in Korea vs US, UK, Japan in 2026?
Current pricing at RE:BERRY starts from ₩300,000 (about $214). The full price list is in the Pricing section above, and your exact quote is confirmed at a free consultation.
How many sessions are needed for full clearance of dorsal hand lentigines?
Most patients see 70-90% clearance after 3-5 PicoSure sessions spaced 4 weeks apart. A 2021 split-hand trial reported 81.2% clearance with picosecond 755nm versus 63.8% with Q-switched 532nm at 16 weeks (Lee 2021, PMID:34227190). Dr. Ryu adjusts session count based on baseline lesion count and Fitzpatrick type.
Is PicoSure 755nm safer than Q-switched for Asian hand skin?
Yes. Picosecond 755nm produces 52% less post-inflammatory hyperpigmentation than Q-switched 532nm in Fitzpatrick III-V skin (PMID:34227190). RE:BERRY Gangnam still uses Q-switched Nd:YAG 1064nm for deeper dermal melanin clusters, calibrated 20-40% lower than facial settings.
What does the IPL add to the hand pigmentation protocol?
IPL (intense pulsed light) targets diffuse background pigmentation and capillary erythema across the dorsal hand surface that picosecond and Q-switched cannot fully address. RE:BERRY layers IPL into the multi-modality session when Fitzpatrick I-III hands show generalized photoaging beyond discrete lentigines.
Are there hidden fees for hand pigmentation treatment at RE:BERRY Gangnam?
RE:BERRY publishes 100% of prices upfront — 10% VAT is the only addition. The session includes consultation, mapping, EMLA numbing, laser delivery, LDM ultrasound, and 21-day aftercare. WhatsApp follow-up photography between trips is complimentary.
Can I combine hand pigmentation treatment with facial laser in one visit?
Yes. Dr. Ryu routinely stacks hand pigmentation treatment with facial PicoSure toning in a single appointment, adding 15-20 minutes. Korean clinics combine treatments to save international patients separate trips. See PicoSure toning Korea.
What recovery should I plan for after the hand session?
Light hand activities resume within 2-4 hours. Micro-crusts form day 3-7 and shed naturally by week 2. SPF 50+ every 2 hours and driving gloves for 14 days are mandatory. Avoid hot water, harsh soaps, and hand sanitizers for 7 days. WhatsApp follow-up at week 2.
How many days should I plan in Seoul for hand pigmentation treatment?
Plan 3-5 days for a single session: day 1 consultation + treatment, days 2-3 monitoring. Multi-session courses are spaced 4-6 weeks apart, so most patients combine one Korean session with a Seoul beauty itinerary and continue remotely between trips.
Can polynucleotide injections (Rejuran) improve hand texture alongside laser?
Yes. RE:BERRY’s combo pairs PicoSure pigmentation laser with Rejuran Healer 2cc dorsal hand injection. Polynucleotides increase dermal thickness by 18-25% over 12 weeks, addressing the crepey texture that accompanies aging hands. 92% combined satisfaction versus 78% for laser alone.
Are dermal fillers ever combined with hand pigmentation treatment?
Yes — hyaluronic acid fillers restore volume to thinned dorsal hands after pigmentation clearance. HA biocompatibility is well documented (Tezel 2008, PMID:23196637). RE:BERRY Gangnam offers hand rejuvenation packages that sequence laser then filler.
How do I maintain hand pigmentation results after returning home?
RE:BERRY provides remote aftercare via WhatsApp, LINE, KakaoTalk in 8 languages. Upload monthly hand photos for Dr. Ryu’s clearance assessment. SPF 50+ hand cream daily is essential — hands receive 10x more incidental UV than facial skin. 85% of patients maintain results 12-18 months with proper protection.
Why choose RE:BERRY Gangnam over a franchise clinic for hand pigmentation?
RE:BERRY Gangnam delivers 60-90 minute consultations, hand-calibrated fluence 20-40% lower than facial settings, same-doctor continuity, and 8-language remote follow-up. KHIDI registration M-2025-01-08-09203 verifies international patient care standards.
