Clarity II Facial Redness — PECHE Clinic, Gangnam Station

Clarity II Facial Redness

Clarity II is a redness and vascular laser that fires 1064nm light in long, sustained pulses (long-pulse) to target stretched blood vessels. This wavelength is well absorbed by hemoglobin — the red, oxygen-carrying pigment protein in red blood cells — and the absorbed light turns to heat, hardening (coagulating) the proteins of the vessel wall. As the hardened vessel is gradually absorbed by the body, the redness that showed through fades step by step. Stretched vessels are thicker than normal ones, hold more blood, absorb more light — and so respond first. Normal vessels mostly remain, carrying blood as before.

▲ The surface is protected by cooling while heat gathers only in the stretched vessels of the dermis

When to Consider It

• Fine capillaries are visible to the naked eye beside your nose or on your cheeks
• Your face flushes after washing it or after a single drink — and takes a long time to settle
• Red marks linger where acne has already calmed
• Redness shows through even under makeup
• Pigment treatments haven't touched the redness

The Redness It Targets

Target	What it is
Stretched capillaries	Vessels thickened enough to show as red lines beside the nose or on the cheeks — makeup doesn't cover them
Redness that won't settle	Vessels spread wide in the dermis (the skin's inner layer beneath the epidermis) that no longer narrow back
Red acne marks	Vessels inside marks left deep and red in one spot

Redness is a problem of stretched vessels, not of pigment (melanin) — so pigment treatments don't resolve it. Conversely, a faint dullness or uneven tone across the whole face may suit a different approach better than this vessel-by-vessel one. Which side yours falls on is confirmed at your assessment and decided together. Redness beyond the face — neck, chest — is assessed by the same standard.

▲ A normal vessel on the left and a stretched vessel on the right — the thicker the vessel in the dermis near the surface, the more the redness shows through

How It's Done

1. Cleansing and makeup removal Leftover makeup keeps the light from entering evenly, so the skin is cleansed first.

2. 3D MetaVu analysis Photographs under standard, polarized, and UV light show where the redness sits and how far it spreads. The redness you see in the mirror and the range the scan reveals can differ.

3. Treatment The 1064nm long-pulse laser is applied. The crux of vascular treatment is raising the dermis's temperature to the needed level without burning the surface — so cryogen gas cools the surface at every pulse, and the skin's surface temperature is measured in real time and shown on the screen.

4. Soothing and guidance After soothing, we go over sun protection and other care.

Results and Recovery

Item	Details
Target	Hemoglobin inside the dermis's stretched capillaries
How it works	The 1064nm long pulse heats and hardens the vessel wall → the hardened vessel is gradually absorbed by the body
Surface protection	Cryogen gas cools the surface at every pulse · surface temperature displayed in real time during treatment
Sessions and spacing	5–10 sessions, 1–2 weeks apart
When results show	Sessions 1–2 usually bring just a clearer tone · you typically start to notice the redness fading from sessions 3–5 (about a month in)
Maintenance	Once every 1–2 months after the course — new vessels naturally form over time
Pain	A light snap, like a rubber band flicked gently
Pain control	Surface cooling, with numbing cream sometimes added depending on the area and intensity
Downtime	No scabbing · faint redness or a tingling that lasts a few hours to a day, then settles
Aftercare	Sunscreen and moisturizer — skin is prone to darkening after treatment, so protection helps reduce marks

This isn't a one-pass removal — it reduces the redness step by step across sessions. Because redness is a condition where new vessels form again over time, maintenance continues after the course. How many sessions you need depends on the cause and depth of the redness.

This device also treats surface blemishes with its 755nm wavelength, but that treatment leaves scabs, so its recovery is different. If redness and blemishes coexist, the order and intensity for each are planned separately at your assessment.

Expected Reactions and Possible Side Effects

Common, temporary reactions — part of the normal response:

• Faint redness or tingling at the treated area, lasting a few hours to a day
• No scabbing with this treatment

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
• Inflammation or wounds at the treatment site — we proceed once it has healed
• Medications that increase light sensitivity (such as some antibiotics or diuretics)
• A recent pigment treatment or peel — we space it out
• Redness from another cause — if a skin condition or a medication you've been applying is behind the redness, managing that cause comes first
• Darker skin tones — pigment in the outermost layer (epidermis) absorbs more energy, so intensity is adjusted around 1064nm, which the epidermis's pigment absorbs less

How PECHE Clinic Does It

We measure first, then decide the treatment. The redness you can see and the range it actually covers are different. The 3D MetaVu scan — standard, polarized, and UV light — shows where the redness sits and how much there is, and sometimes the answer that comes out is "something else comes before this treatment."

We treat by standards built from over 90,000 treatments. Vascular treatment has to raise the dermis's temperature enough without burning the surface, so intensity must come from standards, not feel. The intensity is set by standards built from over 90,000 treatments, and the device measures the skin's surface temperature in real time and displays it on screen. Whichever physician treats you, the same standards apply.

The prep room is behind a glass wall, in full view. The prep room has a glass wall, so while you wait, the preparation and hygiene routine is visible from the waiting area. The more sessions a treatment takes, the more it matters that each one is prepared the same way.

We're honest about what to expect. This treatment doesn't finish in one pass, and maintenance continues after the course as new vessels form. Depending on the cause of your redness, this treatment alone may not be enough. We tell you that first — and we don't push same-day payment or session packages. You're welcome to come in just for a consultation.

Pricing

The cost of redness treatment depends on the area, the range, and the session plan. We confirm the state of the redness in your consultation, then give you a quote.

Location

PECHE Clinic 3F, 364 Gangnam-daero, Gangnam-gu, Seoul Right in front of Gangnam Station, Exit 4

Sessions come around every 1–2 weeks. The shorter the trip, the easier it is to keep that rhythm without missing a session.

FAQ

Q1. Who performs the treatment? A: PECHE physicians who all work to the same intensity standards, built from over 90,000 documented treatments. Intensity is set from the redness distribution confirmed in your scan, and the device displays the surface temperature in real time during treatment — so even if your physician changes, the treatment stays within the same standards.

Q2. How do I know if my redness is the kind this treats? A: If capillaries are visible to the naked eye, or your flushing takes a long time to settle, vessel-based redness is likely. A faint dullness across the whole face, though, may call for a different approach — the distinction matters. We judge from the redness distribution in your 3D MetaVu scan, and if this treatment isn't the fit, we say so.

Q3. Once I finish the course, will the redness stay away? A: Treated vessels harden and are absorbed, but redness itself is a condition where new vessels form again. That's why maintenance continues once every 1–2 months after the course. "Accumulating sessions plus maintenance" is closer to the truth than "done in one course."

Q4. How should I choose a clinic? A: Three things. First, whether they measure and show you the redness before treating — you first need to know whether the redness comes from blood vessels or something else. Second, whether they have the equipment to treat redness and pigment separately when the two are mixed. Third, whether the clinic is easy to reach — you'll be coming back every 1–2 weeks.

Q5. Can I just have a consultation and decide later? A: Yes. See your redness distribution in the scan, hear the expected sessions and the limits, and go home to decide. We don't push same-day payment or session packages at the consultation.
