What Is Pico Laser and How Does It Work at RE:BERRY Myeongdong Seoul
Pico laser delivers energy in trillionths of a second (picoseconds) to shatter pigmentation particles and stimulate collagen remodeling without thermal damage to surrounding tissue. At RE:BERRY Myeongdong, PicoSure 755nm alexandrite pico laser treatment starts from ₩159,000 for a first-visit One Day PicoSure Toning session, with the Dual Toning Package at ₩259,000 combining PicoSure with Genesis laser for comprehensive skin rejuvenation.
What Is Pico Laser and How Does Pico Laser Work?
Pico laser is a picosecond-pulse laser that shatters melanin pigment into micro-particles through photomechanical impact rather than heat, effectively treating melasma, dark spots, acne scars, and dull skin with near-zero downtime in 3-5 sessions, available from ₩159,000 per session at RE:BERRY Myeongdong Seoul.
Understanding what pico laser is and how it works has become essential for anyone researching skin rejuvenation treatments in Korea. Pico laser — short for picosecond laser — fires laser energy in pulses measured in trillionths of a second (10^-12 seconds), compared to nanosecond lasers that fire in billionths of a second. This 1,000-times-faster pulse duration is what makes pico laser fundamentally different from older Q-switched lasers. Instead of destroying pigment through thermal (heat) energy, pico laser shatters melanin particles through a photomechanical pressure wave effect called laser-induced optical breakdown (LIOB). At RE:BERRY Myeongdong, Aesthetic Medicine Specialist Seung-Jae Baek uses the PicoSure 755nm alexandrite pico laser, which is the gold standard pico laser platform for Asian skin types. The 755nm wavelength targets melanin with high specificity while the picosecond pulse duration minimizes thermal damage to surrounding tissue — this is why pico laser treatment has become the preferred laser modality for treating melasma, post-inflammatory hyperpigmentation, age spots, and tattoo removal in Seoul’s aesthetic clinics. Beyond pigmentation, pico laser stimulates collagen and elastin production through the LIOB mechanism, making it effective for improving skin texture, shrinking pores, and softening acne scars. The pico laser treatment at RE:BERRY Myeongdong starts from ₩159,000 for a first-visit One Day PicoSure Toning session and ₩259,000 for the Dual Toning Package that combines PicoSure with Genesis laser toning for enhanced results.

How Pico Laser Treatment Works Step by Step at RE:BERRY Myeongdong
A detailed 4-step breakdown of what happens during a pico laser session and how the technology achieves its results.
Skin Analysis & Pico Laser Parameter Selection
Dr. Seung-Jae Baek examines your skin under a dermatoscope and VISIA imaging system to identify the exact type, depth, and distribution of pigmentation. Epidermal pigment (freckles, sun spots) responds differently to pico laser than dermal pigment (melasma, Hori’s nevus), so precise diagnosis determines the optimal pulse width, fluence (energy density), and spot size. For pico laser treatment at RE:BERRY Myeongdong, parameters are customized to your Fitzpatrick skin type (I-VI) and specific concern. The consultation takes 15-20 minutes and is available in 8 languages.
Skin Preparation & Cleansing
The treatment area is thoroughly cleansed to remove makeup, sunscreen, and surface oils that could absorb laser energy. Unlike ablative laser procedures, pico laser typically does not require numbing cream for standard toning sessions because the ultra-short pulse duration causes minimal thermal sensation. However, for Pico Fraxel (fractional pico laser) treatments targeting deeper scars, topical anesthetic is applied for 20-30 minutes before the procedure. Protective eyewear is provided to shield your eyes from laser light during the pico laser session.
PicoSure 755nm Pico Laser Delivery
The PicoSure handpiece delivers pico laser energy across the treatment area in systematic passes. In toning mode, the laser fires at low fluence across the entire face with the Focus Lens Array diffraction optic, creating millions of microscopic LIOB zones that shatter melanin and stimulate collagen without breaking the skin surface. Each pulse lasts just 550-750 picoseconds — so brief that heat cannot diffuse to surrounding tissue. Patients describe the sensation as a warm tingling or light snapping feeling. For spot treatment of discrete dark spots or age spots, higher fluence is applied to targeted areas. A full-face pico laser toning session takes 15-20 minutes at RE:BERRY Myeongdong, while the Dual Toning Package adds Genesis 1064nm for an additional 15 minutes of deep dermal heating.
Post-Treatment Calming & Recovery
After pico laser treatment, a calming mask and LED phototherapy (Dermio Care at 633nm red light) are applied for 15 minutes to reduce transient redness and accelerate cell repair. A barrier cream and SPF 50 sunscreen are applied before you leave. Redness after pico laser typically fades within 1-3 hours — most patients walk directly from RE:BERRY Myeongdong into the Myeongdong shopping district without any visible treatment signs. Your aftercare guide (available in 8 languages) explains the 48-hour sun avoidance recommendation and gentle skincare regimen to optimize pico laser results.
What to Expect After Pico Laser Treatment at RE:BERRY Myeongdong
- Photomechanical Pigment Destruction: Pico laser shatters melanin via pressure waves, not heat — safer for Asian skin with lower risk of post-inflammatory hyperpigmentation.
- Collagen Stimulation via LIOB: Laser-induced optical breakdown creates micro-cavities that trigger new collagen and elastin production for improved texture.
- Near-Zero Downtime: Pico laser toning causes only 1-3 hours of mild redness with no peeling, crusting, or social downtime.
- Multi-Concern Treatment: One pico laser session addresses pigmentation, pores, fine lines, and skin dullness simultaneously.
- Fewer Sessions Than Q-Switched Lasers: Pico laser achieves comparable results in 3-5 sessions versus 8-12 sessions with older nanosecond technology.
| Timeline | What to Expect |
|---|---|
| Hour 0-3 | Mild redness and warmth that resembles a light sunburn. Subsides within 1-3 hours after pico laser treatment. |
| Day 1-2 | Skin may feel slightly dry or tight. Some patients notice micro-crusting on treated pigmented spots. Normal hydrating skincare is safe. |
| Week 1 | Treated dark spots begin darkening and lifting as shattered melanin rises to the surface. This is a normal part of how pico laser works. |
| Week 2-3 | Darkened spots slough off naturally, revealing clearer skin underneath. Overall skin tone begins brightening noticeably. |
| Month 1-2 | Collagen remodeling from LIOB becomes visible — pores appear smaller, fine lines soften, and skin texture improves progressively. |
| Month 3-6 | Full results visible after completing the recommended 3-5 pico laser sessions at RE:BERRY Myeongdong. Maintenance sessions every 2-3 months sustain results. |

The Science Behind How Pico Laser Works
Peer-reviewed evidence explaining the photomechanical mechanism, LIOB effect, and clinical outcomes of picosecond laser treatment.
Picosecond Pulse Duration and Photomechanical Pigment Destruction
The fundamental principle of how pico laser works lies in its pulse duration. A picosecond equals one trillionth of a second (10^-12 seconds). At this timescale, laser energy is delivered faster than the thermal relaxation time of melanosomes (the organelles containing melanin pigment), which is approximately 10-50 nanoseconds. Because the energy is deposited before heat can diffuse, pico laser creates a photomechanical shockwave that physically shatters melanin particles into micro-fragments small enough for macrophage phagocytosis and lymphatic clearance. This is fundamentally different from Q-switched nanosecond lasers, which rely primarily on photothermal destruction and produce larger melanin fragments that require more sessions to clear.

Laser-Induced Optical Breakdown (LIOB) for Collagen Remodeling
Beyond pigmentation, pico laser technology stimulates skin rejuvenation through laser-induced optical breakdown (LIOB). When the PicoSure Focus Lens Array diffracts the laser beam into 10-micron micro-spots, the concentrated energy at each point creates microscopic vacuoles (cavitation bubbles) in the dermis. These LIOB zones trigger the wound healing cascade — including fibroblast activation, neocollagenesis (new collagen type I and III synthesis), and elastogenesis — without breaking the epidermis. Histological studies show 35-45% increase in dermal collagen density at 3 months post-treatment, explaining pico laser’s effectiveness for pore reduction, fine line improvement, and acne scar remodeling.

PicoSure 755nm Alexandrite: Wavelength Advantages for Asian Skin
The PicoSure platform uses a 755nm alexandrite wavelength, which has optimal melanin absorption characteristics for treating pigmentary lesions in Fitzpatrick skin types III-V (common in Asian populations). Compared to 1064nm Nd:YAG pico lasers, the 755nm wavelength has approximately 5 times greater melanin absorption coefficient, meaning it can achieve effective pigment disruption at lower fluences. This reduced energy requirement translates to less collateral thermal damage and lower risk of post-inflammatory hyperpigmentation — the primary complication concern when treating Asian skin with any laser. Multiple clinical trials on Korean and Japanese patients confirm PicoSure 755nm achieves 60-75% pigmentation clearance in 3-4 sessions with less than 3% PIH incidence.

A comprehensive meta-analysis of picosecond versus nanosecond laser treatments for benign pigmented lesions found that pico laser achieved higher clearance rates in fewer sessions with significantly lower adverse event rates. The photomechanical mechanism of pico laser produces particle sizes averaging 10-100 nanometers versus 100-1000 nanometers with nanosecond lasers, enabling faster phagocytic clearance and reducing the risk of pigment recurrence that often occurs with thermal-based laser modalities.

Frequently Asked Questions About Pico Laser and How It Works
Expert answers from RE:BERRY Myeongdong pico laser specialists.
₩159,000 for a first-visit One Day PicoSure Toning session at RE:BERRY Myeongdong. The Dual Toning Package combining PicoSure pico laser with Genesis 1064nm is ₩259,000 per session. Multi-session packages are available for further savings.
Pico laser fires in picoseconds (trillionths of a second) versus nanoseconds or milliseconds for regular lasers. This 1,000x faster pulse shatters pigment through photomechanical pressure waves rather than heat, resulting in better clearance in fewer sessions with less skin damage.
PicoSure 755nm targets melanin with ultra-short picosecond pulses that create shockwaves, fragmenting pigment into nano-particles 10-100 nanometers in size. These micro-fragments are then naturally cleared by macrophages through the lymphatic system over 2-4 weeks after each pico laser session.
1-2 out of 10 on the pain scale for pico laser toning at RE:BERRY Myeongdong. The sensation is described as mild warm tingling or light snapping. No numbing cream is needed for standard toning. Pico Fraxel for scars uses topical anesthetic and rates 3-4/10.
3-5 sessions spaced 3-4 weeks apart for pigmentation clearance at RE:BERRY Myeongdong. Superficial spots may clear in 1-2 sessions. Deeper conditions like melasma typically require 5-8 sessions. Your doctor will assess your specific needs during consultation.
Pico laser pulses last 550-750 picoseconds versus 5-20 nanoseconds for Q-switched. This means pico laser fragments pigment through photomechanical force into smaller particles, achieving clearance in 3-5 sessions versus 8-12 with Q-switched. Pico laser also carries lower PIH risk for Asian skin.
60-75% of melasma patients see significant improvement after 4-6 pico laser sessions. The PicoSure 755nm wavelength at RE:BERRY Myeongdong treats dermal melasma with less rebound risk than thermal lasers. Maintenance sessions every 2-3 months help sustain results.
LIOB (Laser-Induced Optical Breakdown) creates microscopic cavitation bubbles in the dermis that trigger collagen and elastin production without breaking the skin surface. This is how pico laser improves pores, fine lines, and acne scars beyond just pigmentation removal.
Excellent safety for Fitzpatrick types III-V (most Asian skin). The 755nm PicoSure wavelength at RE:BERRY Myeongdong has less than 3% post-inflammatory hyperpigmentation incidence in clinical studies on Korean patients, making it one of the safest laser options for darker skin tones.
1-3 hours of mild redness for pico laser toning — no peeling, no crusting, no social downtime. Most patients at RE:BERRY Myeongdong walk directly to Myeongdong shopping district after their session. Pico Fraxel has 3-5 days of micro-crusting for deeper scar treatment.
Pico laser achieves 60-75% clearance in 3-5 sessions versus 40-60% with IPL in 5-8 sessions. Pico laser’s photomechanical mechanism is fundamentally more effective at shattering melanin and carries lower PIH risk. Pico laser vs other toning options are discussed during consultation at RE:BERRY Myeongdong.
24 hours after standard pico laser toning is safe for air travel. Apply SPF 50 before and during the flight. Cabin pressure does not affect treated skin. Most international patients at RE:BERRY Myeongdong schedule pico laser on the day before or 2 days before departure.
8+ conditions respond to pico laser: melasma, freckles, age spots, post-inflammatory hyperpigmentation, enlarged pores, fine lines, acne scars (with Pico Fraxel), and tattoo removal. RE:BERRY Myeongdong treats all of these with the PicoSure 755nm platform.
PicoSure 755nm fires first to target pigmentation and stimulate collagen via LIOB. Genesis 1064nm follows to heat the upper dermis at 42-45 degrees, killing bacteria, reducing redness, and boosting overall skin renewal. Combined at ₩259,000 per session at RE:BERRY Myeongdong.
The Focus Lens Array is a diffractive optic that redistributes the PicoSure beam into concentrated micro-spots, amplifying LIOB effect by 20x. This creates deeper collagen stimulation zones in the dermis without increasing surface energy — making pico laser effective for texture improvement beyond pigmentation.
35-45% increase in dermal collagen density is documented at 3 months post-pico laser treatment through the LIOB mechanism. This collagen remodeling tightens pore walls and smooths fine-textured irregularities. 3-5 sessions of pico toning for glass skin at RE:BERRY Myeongdong is recommended.
2 weeks before: avoid sunburn and tanning beds. After treatment: strict SPF 50 application for 4 weeks minimum. UV exposure can trigger post-inflammatory hyperpigmentation on freshly laser-treated skin. RE:BERRY Myeongdong provides complimentary sunscreen after each pico laser session.
PicoSure uses 755nm alexandrite wavelength with patented Focus Lens Array. PicoWay offers dual 785nm and 1064nm wavelengths.
