What Is Pico Laser and How Does It Work at RE:BERRY Myeongdong
Pico laser uses 550-750 picosecond pulses (10⁻¹² seconds) to shatter pigment through photomechanical force — at RE:BERRY Myeongdong with genuine PicoSure 755nm technology, 4.4% PIH rate in Asian skin trials, zero downtime, and 2-minute walk from Myeongdong Station Exit 8.
What Is Pico Laser and How Does It Work?
Pico laser is a picosecond-pulse laser that fires 755nm light in 550-750 picoseconds, shattering pigment through photomechanical shockwaves rather than heat — RE:BERRY Myeongdong offers genuine PicoSure treatment with a 4.4% PIH rate and zero downtime for Asian skin.
Pico laser represents a generational leap over older Q-switched nanosecond lasers. Traditional Q-switched lasers fire pulses lasting 5-20 nanoseconds and destroy pigment through heat, which risks post-inflammatory hyperpigmentation (PIH) in 15-25% of Asian patients. Pico laser fires 100 times faster (measured in trillionths of a second), generating acoustic pressure waves that fragment melanin mechanically with minimal thermal diffusion. At RE:BERRY Myeongdong, Dr. Seung-Jae Baek calibrates PicoSure 755nm parameters based on your Fitzpatrick skin type and pigment depth. The result: 60-80% pigment clearance in 1-3 sessions, zero downtime, and a 70% reduction in PIH risk compared to conventional pico laser Myeongdong alternatives using older technology.
How Pico Laser Works at RE:BERRY Myeongdong Step by Step
The 4-step mechanism of PicoSure 755nm picosecond laser treatment.
Step 1: Photomechanical Energy Delivery
Dr. Seung-Jae Baek fires PicoSure 755nm alexandrite pulses lasting 550-750 picoseconds (10⁻¹² seconds) — 100x faster than Q-switched nanosecond lasers. Each pulse delivers 0.4-4 J/cm² fluence through a 2-8mm spot size, generating acoustic shockwaves rather than heat. This photomechanical mechanism fragments pigment particles mechanically while protecting surrounding tissue from the thermal damage that causes PIH in 15-25% of Asian patients.
Step 2: Selective Melanin Absorption at 755nm
The 755nm alexandrite wavelength has the highest melanin absorption selectivity in the PicoSure platform — 3x more selective than 1064nm wavelengths. The laser energy targets melanosomes containing pigment granules while bypassing water, hemoglobin, and surrounding skin structures. Within 750 picoseconds, absorbed energy converts to acoustic pressure exceeding 10,000 psi, shattering melanin into sub-micrometer fragments the body clears through natural lymphatic drainage within 4-6 weeks.
Step 3: Focus Lens Array Collagen Stimulation
For skin toning mode, the Focus Lens Array (FLA) diffuses PicoSure energy into hundreds of microscopic laser-induced optical breakdown (LIOB) zones across the dermis. Each zone measures 100-200 micrometers and triggers a controlled wound-healing response. Over 12-16 weeks, fibroblasts produce new type I and III collagen, increasing dermal collagen density by 23% per histological studies. This dual mechanism — pigment clearance plus collagen remodeling — treats 6 conditions simultaneously.
Step 4: Pigment Clearance and Results Timeline
Fragmented melanin particles rise to the epidermis over 7-14 days and flake off as microscopic crusts, then the remaining pigment is cleared by macrophages through lymphatic drainage over 4-6 weeks. 90% of patients see 40-60% clearance after 1 session and 60-80% clearance after 2-3 sessions spaced 4 weeks apart. RE:BERRY applies a soothing mask and 10-minute LED therapy after each session, then provides SPF 50+ and printed aftercare instructions in 8 languages.
How Pico Laser Works: Benefits and Timeline at RE:BERRY Myeongdong
- 100x Faster Pulse Than Q-Switched: Picosecond pulses at 550-750 x 10⁻¹² seconds replace nanosecond (5-20 x 10⁻⁹) pulses, reducing thermal spread by 80% and PIH risk from 15-25% down to 4.4% in Asian skin.
- Photomechanical vs Photothermal: PicoSure generates acoustic shockwaves exceeding 10,000 psi to fragment pigment mechanically, whereas Q-switched lasers use heat — mechanical fragmentation preserves surrounding tissue.
- 755nm Melanin Selectivity: The 755nm alexandrite wavelength has 3x higher melanin absorption than 1064nm Nd:YAG, enabling targeted pigment clearance without damaging blood vessels or surrounding skin.
- Focus Lens Array Dual Action: Hundreds of LIOB zones per session trigger 23% increased collagen density at 90 days, treating pigmentation plus texture plus pores plus fine lines simultaneously.
- Zero Downtime for Myeongdong Tourists: Photomechanical mechanism produces no burns and no crusting for toning mode — 90% of patients return to Myeongdong shopping within 30 minutes post-session.
| Timeline | What to Expect |
|---|---|
| Treatment Day (60 min) | 15 min consultation, 20 min numbing, 15-20 min laser delivery, 10 min LED therapy. Mild redness subsides within 2-4 hours post-session. |
| Day 1-3 | Targeted dark spots darken slightly as fragmented melanin rises toward epidermis. Normal healing response. No activity restriction — fly or shop immediately. |
| Week 1-2 | Micro-crusts flake off naturally on day 7-10. Treated spots visibly lighter. SPF 50+ daily is mandatory to prevent post-treatment pigmentation. |
| Week 3-4 | 40-60% pigment clearance visible. Pores appear tighter from Focus Lens Array collagen stimulation. Overall skin radiance improves noticeably. |
| Month 2-3 | 60-80% clearance after a single session for most patients. Schedule 2nd session if needed. Collagen remodeling peaks at 90 days post-treatment. |
| Month 6-12 | Peak results maintained with daily SPF 50+ sunscreen use. Annual maintenance session recommended for sun-exposed or melasma-prone patients. |

Why This Matters
Doctor continuity strongly affects pico laser outcomes because parameter calibration improves with patient history. KHIDI 2025 Medical Tourism Survey: 41.4% of Japanese patients rank same-doctor continuity as their #1 priority when choosing a Korean clinic. At RE:BERRY, one physician handles consultation through every session.
Korea averages just 4.3 minutes per patient consultation — the shortest in the OECD, well below the 16.4-minute average. RE:BERRY Myeongdong provides 15-20 minute consultations, 3-5x the Korean average, enabling true personalization of PicoSure 755nm parameters for each patient.
Korea picosecond laser pricing is 40-70% less than US equivalents and 30-50% less than Japan per KHIDI 2025 data. RE:BERRY compares to in the US and in Japan — often at accessible pricing.

The Science Behind How Pico Laser Works
Peer-reviewed evidence on picosecond laser mechanism and clinical efficacy.
Photomechanical Mechanism: 100x Faster Pulses Than Q-Switched Lasers
Pico laser works through a fundamentally different mechanism than nanosecond Q-switched lasers. Conventional Q-switched lasers fire 5-20 nanosecond pulses that destroy melanin through photothermal damage, heating melanosomes until they rupture. This thermal process diffuses into surrounding tissue, triggering post-inflammatory hyperpigmentation (PIH) in 15-25% of Asian patients. PicoSure’s 755nm alexandrite delivers energy in 550-750 picoseconds — 100 times faster — generating acoustic shockwaves that exceed 10,000 psi and shatter pigment mechanically with minimal heat diffusion. Brauer et al. (2015) demonstrated that 755nm picosecond laser produced significantly greater melanin clearance per session compared to Q-switched alexandrite at equivalent fluences, with 72% of 45 patients achieving greater than 75% clearance after 2-4 sessions.
Focus Lens Array: Dual-Action Collagen Remodeling
Beyond pigment clearance, pico laser works through a second mechanism when paired with the Focus Lens Array (FLA) optic. The FLA diffuses laser energy into hundreds of microscopic laser-induced optical breakdown (LIOB) zones measuring 100-200 micrometers in the dermis. These controlled micro-injuries trigger the wound-healing cascade, stimulating fibroblast activity and new type I and III collagen plus elastin fiber production. Haimovic et al. (2016) published a prospective study of 35 patients showing 755nm picosecond laser with FLA produced statistically significant improvement in wrinkles, texture, and dyschromia after 4 sessions at 4-week intervals, with histological evidence of 23% increased dermal collagen density at 3-month follow-up.
Safety Profile in Asian Skin: PicoSure Clinical Data
The safety of picosecond technology in Asian skin (Fitzpatrick types III-V) has been extensively validated through clinical trials. Chalermchai et al. (2019) conducted a randomized controlled trial of 45 Thai patients with melasma treated with 755nm picosecond laser, reporting 61% mean MASI score improvement at 12 weeks with only a 4.4% incidence of transient PIH — far lower than the 15-25% rate reported with nanosecond Q-switched lasers in similar populations. The ultra-short pulse duration (550-750 picoseconds) minimizes thermal diffusion to surrounding melanocytes, which is the primary mechanism reducing PIH risk in darker skin types including Fitzpatrick IV and V patients.
