What is Age Spots Hands Treatment at RE:BERRY Gangnam?

Age spots hands treatment at RE:BERRY Gangnam removes solar lentigines on the dorsum of the hands with PicoSure 755 nm picosecond laser (550-750 ps, 0.7-2.0 J/cm²) and Q-switched Nd:YAG 1064 nm toning, achieving 70-90% pigment clearance across 3-5 sessions. Pricing starts at ₩159,000 ($114 USD) for the One-Day PicoSure Hand session, ₩259,000 ($185 USD) for the Dual Toning Hand Rejuvenation Package, and ₩399,000 ($285 USD) for the Hand Rejuvenation + Rejuran package. Medical Director Dr. Yoon-Gon Ryu (License 131644) maps each hand lesion by depth and Fitzpatrick type during a 60-90 minute consultation, with the same doctor across all sessions. Korean clinics deliver 50-70% lower per-session pricing than US dermatology clinics ($350-650), and RE:BERRY Gangnam operates 365 days a year with 8-language coordination.

Hand skin has thinner dermis and lower melanocyte density than facial skin, so age spots hands treatment at RE:BERRY Gangnam uses lower fluence settings and tighter spot spacing to avoid post-inflammatory hyperpigmentation. The dorsal hand surface receives picosecond fragmentation followed by LDM ultrasound soothing to reduce thermal residual heating.

International patients commonly bundle hand and face age spot laser in one Seoul trip, with one session per 4-6 week interval across the 3-5 session course. Combination with Rejuran salmon-DNA dermal repair restores volume to thinning hand skin.

Treatment Process

How Age Spots Hands Treatment Works at RE:BERRY Gangnam

Step 1: Hand Skin Analysis and Age Spot Mapping (20-30 min)

Your physician examines both hands under dermatoscopy and UV Wood’s lamp illumination to identify all melanin deposits. Each age spot is classified by epidermal depth (0.1-0.3mm) versus dermal involvement (0.3-0.8mm on hands), diameter (2-20mm range), and color intensity using a standardized 4-grade scale. The thin dorsal hand skin (0.5-1.0mm total thickness) requires 20-40% lower fluence than facial protocols. Your physician maps 10-50+ age spots across both hands during the 20-30 minute assessment to create your age spots hands treatment plan.

Step 2: Topical Anesthesia and Hand Preparation (15-20 min)

EMLA numbing cream (2.5% lidocaine + 2.5% prilocaine) is applied to the dorsal surface of both hands for 15-20 minutes under occlusive wrap to achieve full anesthetic depth in the thin hand skin. The treatment area is cleansed with 0.5% chlorhexidine solution, removing oils and sunscreen residue that could scatter laser energy. Hand positioning supports are placed to ensure stable delivery. This preparation achieves 90-95% pain reduction for the age spots hands treatment session.

Step 3: PicoSure 755nm Laser Delivery to Hands (20-30 min)

The physician delivers PicoSure picosecond laser at 755nm with pulse duration of 550-750 picoseconds, calibrated to 0.5-1.5 J/cm² fluence for the thinner hand skin. Each age spot on the hands receives 3-6 passes with a 2-3mm spot size precisely matched to lesion boundaries. For a typical bilateral treatment of 30-50 age spots, the physician delivers 300-600 total pulses over 20-30 minutes. The picosecond mechanism shatters melanin into 5-10nm particles that macrophages clear within 14-21 days.

Step 4: Post-Laser Hand Care and Aftercare Protocol (10-15 min)

LDM ultrasound therapy at 3-10 MHz is applied to both hands for 10 minutes to reduce post-inflammatory redness by 40-50%. A ceramide-rich barrier cream is applied over treated areas. Your physician provides a 21-day hand-specific aftercare protocol: SPF 50+ reapplication every 2 hours (hands are frequently exposed during daily activities), protective gloves for driving recommended for 14 days, and avoidance of harsh soaps and hand sanitizers for 7 days. RE:BERRY schedules a 2-week follow-up to photograph results and plan your next age spots hands treatment session.

Why This Matters

Doctor continuity is critical for age spots hands treatment because hand skin responds differently than facial skin across multiple sessions. KHIDI’s 2025 Medical Tourism Survey found 41.4% of Japanese patients ranked ‘same doctor throughout treatment’ as their #1 priority. RE:BERRY assigns one doctor per patient for all sessions.

Korea’s average outpatient consultation is 4.3 minutes — the shortest in the OECD (16.4 min average). RE:BERRY’s 60-90 minute age spots hands treatment consultations represent 15-20x the national average, ensuring precise mapping of every lesion on both hands.

Korean aesthetic procedures cost 40-70% less than the US and 30-50% less than Japan — using the same FDA/MFDS-cleared devices. Source: KHIDI 2025, ASDS Annual Survey.
