PicoLite Fractional Laser — PECHE Clinic, Gangnam Station
1064nm divided into many points, passing the epidermis to leave stimulus deep in the dermis · Scars and pores · Face · Right by Gangnam Station Exit 4
PicoLite Fractional Laser
The PicoLite Fractional Laser takes the PicoLite Black's 1064nm light — the one used for pigment — and fits a plate studded with many small lenses (a micro lens array) in front of it. Light that came out as a single stream splits into hundreds of points as it passes the plate. Each point carries concentrated force while the skin between the points stays untouched — and that remaining healthy tissue aids the repair, so the whole face can be treated at once, with a quick recovery.
The wavelength — the value that describes a light's color — is long at 1064nm, so these points are absorbed less by the epidermis's pigment and travel deep into the dermis. That is why this mode targets deeply depressed scars rather than shallow marks. The manufacturer's official material likewise states that this light, fired in an extremely short burst, helps collagen rebuild in the dermis without damaging the skin's surface.
▲ Stimulus points land deep in the dermis past the epidermis, and the healthy tissue between the points stays as it is
When to Consider It
- The shadows of depressed marks show through even under makeup
- Pores, depressed marks, and rough texture are mixed on one face
- Your skin tone is darker and you worry a texture treatment will leave marks
- Treatments that remove the skin's surface layer feel like too long a recovery
- You're mid-course on pigment care and want the texture addressed too
The Scars and Pores It Treats
| Target | What it is |
|---|---|
| Shallow depressed marks | Where acne healed, the dermis didn't fully recover; its collagen thinned, leaving the surface gently sunken |
| Enlarged pores | The collagen that kept the pore tight has loosened, leaving the pore open |
| Rough texture | The dermis's collagen is uneven, leaving the surface looking bumpy |
▲ Beneath a depressed mark, both the dermis and its collagen are thinned — the stimulus points land right there
Scars come in kinds. A mark with a gently sunken base, like the one drawn above, is approached by building the dermis back up. A scar with angular borders and a base bound down hard still has tissue pulling from beneath — and a different method that cuts that tissue directly may come first. If pigment is the main concern, it's handled by the same device's toning mode, decided separately at the consultation.
How It's Done
1. Cleansing and makeup removal The surface is cleansed first so the light enters evenly.
2. 3D MetaVu analysis Photography confirms where the marks sit and what state the pores and texture are in.
3. Numbing cream Applied, then about 20 minutes of waiting. This lens-fitted mode is more intense than toning, so numbing is the default.
4. Treatment With the point-splitting lens fitted, each area is treated in turn.
5. Soothing and guidance After soothing, we go over the redness course and sun protection.
Results and Recovery
| Item | Details |
|---|---|
| Target | Collagen in the deep layer of the dermis |
| How it works | The multi-lens plate divides the 1064nm light into hundreds of points, leaving stimulus points in the deep dermis — the healthy tissue between the points aids repair |
| Areas | Face |
| When results show | Not right after — gradually over 2–3 months, as collagen fills in at the deep stimulus points |
| Sessions and spacing | 3–5 sessions at 3–4 week intervals, matched to the skin's repair cycle · adjusted by scar depth and count |
| Pain | A hot, stinging heat crackles across the skin's surface like scattering sparks — a different feeling from toning's light rubber-band flick |
| Pain control | Numbing cream applied and about 20 minutes' wait before starting · tell us how it feels mid-session and we adjust the intensity |
| Downtime | No scabbing · the treated area turns red for a day or two, then settles |
| Aftercare | Sunscreen and moisturizer |
There's a reason it takes time. This treatment doesn't fill the sunken spots directly — it has the skin build its own collagen while repairing the stimulus points. The change appears not right after but gradually over 2–3 months, and the difference shows as the sessions accumulate.
Why this wavelength comes first for darker tones is absorption. With more pigment in the epidermis, a short wavelength is absorbed at the surface first and the epidermis bears the burden. 1064nm is absorbed less by the epidermis's pigment, so that burden is smaller. Still, any wavelength can leave marks if pushed too hard — so we start at a lower intensity matched to your tone.
Expected Reactions and Possible Side Effects
Common, temporary reactions — part of the normal response:
- Redness at the treated area for a day or two, then settling
This treatment doesn't leave scabs.
Anything beyond this is uncommon. If a reaction lasts longer than expected or worsens, contact us and we'll check it with you.
What We Check Beforehand
If any of these apply to you, let us know during your consultation. We adjust the timing or lower the intensity.
- Recent strong sun exposure or tanning — we wait until the pigment settles
- Active inflammatory acne or wounds at the treatment area — we proceed after they calm
- A keloid history (scars that heal raised)
- Medications that increase light sensitivity, or recent oral acne medication
- A recent peel or pigment treatment — we space it out
- A history of cold sores (herpes) — they can recur after stimulation, so tell us in advance
- Pregnancy or breastfeeding
How PECHE Clinic Does It
We sort the scar's kind first. Two depressed marks can look alike yet need different approaches, depending on whether the base is gently sunken or bound down hard. The 3D MetaVu photographs and records pore, texture, and line distribution; whether the base is tethered is determined by examination — pressing and gently pulling the skin. If this method isn't the fit, we say so.
▲ We look at the photographed distribution together and decide where to start
No single method fixes every scar. Scars and pores have several causes. We keep separate approaches — one for texture, one that cuts tissue bound at the base, one that lightens pigment — and set the order based on your assessment. The order is: inflammation control → releasing tethered scars → regeneration (this treatment) → pigment clearing.
We treat by standards built from over 90,000 treatments. The deeper a method reaches, the more the intensity ceiling decides the recovery. Standards per area and skin tone are set in advance and the treatment stays within them — whichever physician treats you.
The prep room is behind a glass wall, in full view. You can see the preparation and hygiene routine through the glass wall from the waiting area.

We don't propose raising the intensity to cut the session count. Pushing too hard can lengthen recovery and leave marks. We don't push same-day payment or session packages either. You're welcome to come in just for a consultation.
Pricing

FAQ
Q1. Who performs the treatment? A: PECHE physicians who all work to the same standards, built from over 90,000 documented treatments. Whether a scar is tethered is sorted by examination before deciding at what depth the stimulus points go — and even if your physician changes, the treatment stays within the same standards.
Q2. How do I know if my scars are the kind this improves? A: Marks with gently sunken bases and soft borders are close to this method's target. Scars with angular borders whose base doesn't lift when pressed still have tissue pulling from beneath — those may first need the approach that cuts that tissue. We confirm by photography and examination, and tell you.
Q3. Will there be scabs? Can I go to work the next day? A: This isn't a method that removes the surface layer, so no scabs form; a passing redness settles on its own. How long it lingers varies with intensity and area — if you have an important event coming up, tell us before the session and we'll adjust around it.
Q4. I'm mid-course on pigment treatment — can I have this too? A: Even on the same device, lightening pigment and treating texture serve different goals. Running both at once can lengthen recovery, so whether to do them the same day or separately is decided at the consultation, from your skin's condition and recovery margin.
Q5. How should I choose a clinic? A: Three things. First, whether they sort the scar's kind and show you their basis. Second, whether they keep separate approaches for texture, tethered scars, and pigment — this isn't a concern one method resolves. Third, whether the clinic is easy to reach across the spaced sessions.
