The downtime — give it to me straight, day by day.
Is CO2 safe for Asian skin, or is the PIH risk real?
CO2 or Potenza/microneedling for acne scars — how do you choose?
From ₩10,000 — what does spot work versus full-face actually cost?
All five come up most weeks in Busan. The sections below answer them in order — the ablative mechanism and what it uniquely fixes, an unvarnished day-by-day downtime, honest PIH management for Asian skin, the scar-tool decision, and real pricing per scope.
CO2 Fractional · JRYN Seomyeon
What Is CO2 Fractional?
Ablative columns, the resurfacing gold standard.
Fractional CO2 vaporises microscopic columns of skin in a controlled grid — physically removing damaged tissue while leaving the surrounding skin intact to drive rapid healing. It is the deepest, most decisive resurfacing tool dermatology has, which is exactly why its downtime is real.
What ablation buys that gentler tools cannot: pitted acne scars re-levelled, rough and thickened texture genuinely resurfaced, raised lesions removed at their base. Depth and density are dialled per indication — spot work from ₩10,000 on the published list at our Busan clinic, with your scope, price and honest downtime all stated before booking.
How It Works
The science, without the hype.
Ablation is the mechanism — controlled removal, then rebuild. Here is the sequence.
01
Fractional ablation
The laser vaporises micro-columns in a grid — removing damaged tissue physically, not just heating it.
02
Intact-skin healing
The untouched skin between columns drives fast re-epithelialisation — the fraction in fractional is why a week, not a month.
03
Wound-healing collagen
The controlled injury triggers the deepest collagen response on the laser menu — remodelling that matures over three to six months.
04
Depth per indication
Light passes for texture, deep dense passes for pitted scars, precise spots for lesions — one platform, dialled honestly per job.
What CO2 Fixes
The jobs that need actual resurfacing.
The examination matches depth to indication — and routes non-CO2 jobs elsewhere honestly.
Pitted acne scars
Signature
Rolling and boxcar scars re-levelled by depth-matched dense passes — CO2's home ground.

01
Indication reading
The doctor confirms yours is a CO2 job at our Busan clinic — and routes pigment-led or laxity-led cases to the right tools instead.
02
Photos, scope and downtime talk
Fixed-frame photos, written scope and price — and the downtime conversation before booking, day by day, honestly.
03
Numbing
Topical anaesthetic for thirty to forty minutes — ablative work deserves proper preparation, and we take it.
04
The passes
Depth and density per the plan — twenty to forty minutes of methodical grid work, heat and pinprick sensation through the numbing.
05
The healing week
Redness, grid marks, then flaking — three to seven days scaling with depth, managed with our written aftercare.
06
The remodel
First texture change at week four; remodelling matures to month three to six — reviewed by message after you leave Busan.

The Healing Week
Day by day, with nothing softened.
When
What you will notice
What to do
Day 0–1
Treated zones read sunburn-red with a visible micro-grid; warmth and tightness through day one.
Ointment per the written protocol; cold air helps. No make-up yet.
Day 2–4
The bronzing-and-flaking phase — grid darkens, then sheds. This is the part photos never show; we show it.
Do not pick or peel — PIH lives in picked skin. Gentle cleanser, ointment, shade.
Day 5–7
Fresh pink skin emerges; deep plans finish shedding, light plans are make-up-ready.
Mineral make-up from re-epithelialisation. SPF becomes non-negotiable for three months.
Week 4 → Month 6
Texture change reads at week four; collagen remodelling keeps improving scars to month six.
Fixed-frame photos at week four and twelve referee it — sent by message from home.
Honest Suitability
Who it suits in Busan — and who should wait.
A good fit if you…
Pitted acne scars wanting the deepest non-surgical re-levelling
Rough, thickened texture that gentler lasers have plateaued on
Raised lesions wanting precise base-level removal
Able to plan an honest three-to-seven-day healing week
Busan visitors with seven-plus days — the shed completes before the flight
Better to wait if you…
Pregnancy — deferred as standard
Active acne flares or infection in the field — calmed first
Recent isotretinoin courses — timing per current guidance, screened at exam
Unmanaged tanning or melasma-prone skin without prep — PIH risk is addressed first, honestly
After your treatment
Ointment and gentle cleansing per the written protocol through the shed
Never pick or peel the grid — PIH lives in picked skin
Mineral make-up from re-epithelialisation; SPF religiously for three months
Week-four and week-twelve photos referee the remodel
Honest limits
CO2 resurfaces; it does not lift laxity or clear deep pigment — different tools, said plainly
Deep scars take two to three sessions — single-session miracles are marketing
PIH risk in Asian skin is real and managed, not denied — prep, technique and SPF are the treatment too
Our Medical Team
Is CO2 safe for Asian skin, honestly?
Safe when respected, risky when rushed. Asian skin carries a real post-inflammatory hyperpigmentation risk after ablative work — so at our Busan clinic the PIH management is built into the plan: conservative depth-density settings for the skin type, pre-treatment prep where indicated, an aftercare protocol that treats SPF as medication, and honest sequencing when melasma is in the picture. Treated that way, CO2 has been resurfacing Asian skin superbly for decades — including in this clinic, daily.
Three doctors, one standard of care.
Every CO2 plan at JRYN Busan Seomyeon is indication-matched and performed in person by one of our doctors
From the Founder
Read and performed in person by one of our doctors.
CO2 is the laser I respect most — it does what nothing gentler can, and it punishes shortcuts. My rules in Busan are fixed: the downtime talk happens before booking, the settings match the skin in front of me, and nobody leaves without the aftercare that protects the result. Do those three, and this machine changes faces.

Quick Answers
CO2 or RF microneedling for acne scars — how do you choose?
By scar type and downtime budget. Pitted, sharply-edged scars (boxcar, deep rolling) respond best to ablative re-levelling — CO2's territory, at the cost of a real healing week. Tethered or mixed scars with less downtime room lean RF needling (Potenza, Virtue from ₩50,000–200,000), gentler per session across more sessions. Most serious scar programs at our Busan clinic sequence both — and the exam writes which leads.
What does the downtime honestly look like for a visitor?
Plan seven days in Busan for deep work: treat on day one, spend days two to four in the bronzing-and-flaking phase (sightseeing in SPF and a hat is fine; beach and sauna are not), emerge pink around day five, and fly home make-up-ready. Light texture passes compress to three to five days. We schedule to your flight, not our convenience.
Everything Else You Might Ask
CO2 fractional questions in Busan.
Spot and lesion work from ₩10,000 on the published list; texture and scar plans are scoped and priced in writing at the exam, depth and coverage decided honestly. No foreigner markup anywhere on the list.
Yes — English, Japanese (日本語) and Chinese (中文). We are a 5-minute walk from Seomyeon Station Exit 2, and healing photos are reviewed on WhatsApp after you fly home from Busan.
Physical texture: pitted scars, thickened rough skin, raised lesions. Ablation removes tissue rather than heating it — the category difference that makes CO2 the endpoint tool when resurfacing is the actual job.
Under thirty to forty minutes of proper topical numbing at our Busan clinic: heat and pinprick sensation, intense in moments, tolerable throughout. The healing week is the truer cost, and we price it honestly in the consultation.
Three to five days for light texture passes, five to seven for deep scar work — redness, a visible grid, bronzing and flaking, in that order. The full day-by-day is on this page and repeated in writing at booking.
With PIH-aware settings, prep where indicated and disciplined SPF aftercare — yes, and it is performed on Asian skin here daily. Without those, the PIH risk is real, which is why they are not optional at our Busan clinic.
Two to three depth-matched sessions, six to twelve weeks apart, for most pitted scarring — written into your plan up front. Anyone promising one-session scar erasure is selling the photo, not the physics.
First texture change at week four, with collagen remodelling improving scars through month three to six. The week-twelve fixed-frame photo is where scar plans prove themselves.
Yes — precise base-level ablation from ₩10,000 per lesion, usually in one visit, with three-to-seven-day scab healing. Suspicious lesions are assessed medically first, always.
Ablative removes; non-ablative heats. Real pits and thickened texture need removal — CO2. Milder texture and tone goals with minimal downtime lean non-ablative. The exam matches the tool to the actual problem rather than the marketing.
Yes, sequenced — exosome application immediately after (calmer healing), boosters and energy devices on their own timelines afterward. One written Busan plan orders it; nothing else touches skin during the shed.
Yes — acne-scar programs book heavily across genders at our Busan clinic, and thicker male skin often takes depth well. Beard zones are mapped around.
From day two onward, cabin air just feels dry on healing skin — ointment handles it. Most visitors prefer flying at day five to seven, shed complete. We schedule to your ticket.
Retinoids for one week, active tanning for two, and recent isotretinoin is screened per current guidance at the exam. Arriving un-tanned is the single biggest PIH-risk reducer you control.
You trade a week of patience for months of pigment — picking is the primary self-inflicted PIH route. The written aftercare exists so the result you paid for survives your own fingers.
Visibly smoother, re-levelled texture from week four, with scar depth reduced meaningfully — not erased — across a two-to-three-session program, refereed by fixed-frame photos. What CO2 does not do: lift laxity, clear deep pigment, or heal without its honest week.
