CO2 fractional laser in Busan Seomyeon

What does fractional CO2 do, and when is it worth a week of healing in Busan?

A fractional CO2 laser emits 10,600 nm, which water absorbs so completely that the beam vaporises tissue where it lands. Split into a grid of microscopic columns, it removes thousands of tiny cores of skin to a chosen depth and leaves intact skin between them, so the wound heals in days rather than weeks and the heat around each column tightens and remodels the dermis as it does. No other device reaches as deep or triggers as much collagen in one session, which is why CO2 remains the tool for deep acne scars, heavy texture, surgical scars and the deepest lines, and why it costs a week.

At Boom Dermatology, CO2 fractional is the last tier of the resurfacing and scar plans, used when Potenza, Scorpio or UltraClear would not do enough, and used conservatively on Asian skin, where the heat it leaves is the darkening risk every setting is designed around. It is priced per area at consultation because a spot field, a cheek and a full face are different sessions. The same laser, in precision mode, is the mole removal tool at ₩5,500 per lesion.

CO2 fractional vs UltraClear vs Potenza: which deep treatment should you choose in Busan?

Three deep options at our Busan skin clinic, by heat and by healing. The doctor reaches for CO2 last, when the others would not do enough.

Device	Best for	Time	Downtime	Price
CO2 Fractional	Deepest rebuild; scars, heavy texture; most heat, most healing	30–40 min	7–10 days	on consultation
UltraClear	Cold-fibre erbium ablation; deep texture with less heat	30–40 min	5–7 days	₩1,540,000
Potenza	RF microneedling at depth; scars and pores, no surface ablation	40 min	1–3 days	₩440,000
Scorpio	Deep tethered scars remodelled from the base	40 min	2–3 days	₩440,000

Every option in the table is available at Boom Dermatology in Busan Seomyeon, performed by the doctor, with the VAT-included price shown.

Downtime after CO2 fractional, day by day

Given straight. Day one to three: raw, weeping, swollen; ointment, no make-up. Day four to seven: a bronze crust peels to pink new skin. Week two to four: pink, make-up covers it, strict sunscreen. Month one to three: pink fades, collagen fills. Fly after three days at the earliest. The sunscreen rule is not aftercare; it is what prevents the dark mark.

How deep does CO2 go, and what does that depth buy?

Adjustable, from the upper dermis to well below the base of a deep scar; the deeper the columns, the more collagen the healing builds and the longer the healing takes. What depth buys is a result in one session that lighter tiers need a course to approach, and for a deep pitted field it buys something they cannot reach at all. The doctor at Boom Dermatology sets depth per field and writes it on your record.

The downtime, straight, day by day?

Three raw days with ointment and no make-up, four days of crust and peeling, two to four weeks of pink that make-up covers, and months of slow filling. Ten days before you look untreated. Visitors book it at the start of a trip and fly on day four at the earliest; residents take a week off.

Is CO2 safe for Asian skin?

Safe with respect for the risk, which is real: post-inflammatory darkening in skin with more melanin. At our Seomyeon skin clinic that means fractional only, conservative density, a pigment-calming regimen before and after, strict sunscreen, and choosing UltraClear or RF instead when the skin is pigment-prone. We will say no to CO2 on melasma skin and mean it.

CO2 or Potenza for acne scars?

Potenza first, for most. RF microneedling remodels scar fields from below without ablating the surface, with one to three days of downtime, and it is enough for rolling and shallow boxcar scars. CO2 is for the deep pitted field that needles cannot lift. Many plans alternate them; the scar page sets out the sequence.

What does spot work versus full face cost?

Different sessions, priced at consultation at Boom Dermatology in Busan: a single scar or small field is a short session, a cheek a longer one, a full face the longest, and density and depth change each. The price is written before anything starts, VAT included, the same for every patient; the per-lesion precision mode for moles is ₩5,500 to ₩33,000.
