CO2 laser is an ablative fractional resurfacing treatment that uses a carbon dioxide laser at a 10,600 nm wavelength to precisely vaporise tiny columns of skin. Rather than treating the whole surface at once, the fractional pattern leaves healthy skin between each column, which speeds healing while triggering a wound-repair response that rebuilds smoother collagen. It is one of the more powerful resurfacing tools in dermatology, used for atrophic acne scars, rough texture, enlarged-looking pores, and fine wrinkles.
Because it is ablative, CO2 laser removes surface tissue and involves real downtime, typically several days of redness, swelling, and flaking as new skin forms. That trade-off is why it delivers meaningful texture and scar improvement that gentler, non-ablative options often cannot match in the same number of sessions. The energy, density, and depth are all adjustable, so the treatment is tailored to your concern and skin tone rather than applied at a fixed intensity.
At Reberry Clinic, CO2 laser is consultation-led and delivered in English; the clinic’s doctors assess your skin type, scar depth, and goals before choosing settings. International patients are supported across our three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport), with Dr. Yoongon Ryu leading care at our Gangnam (Seoul) location near Gangnam Station.
CO2 laser works by fractional photothermolysis: the 10,600 nm beam is split into a grid of microscopic treatment zones, each vaporising a narrow column of epidermis and dermis while sparing the skin around it. This ablative action removes damaged surface tissue and creates controlled micro-wounds, and the surviving skin between columns drives rapid re-epithelialisation, usually over about 7 days, while collagen remodelling continues for several months. Because CO2 is strongly absorbed by water in tissue, it is efficient at both resurfacing the surface and delivering heat into the dermis, which is what smooths scars and stimulates new collagen. The doctor adjusts 3 key parameters, energy, density, and depth, so a light rejuvenation pass differs markedly from an aggressive scar-resurfacing session. Deeper, denser settings improve scars more but extend downtime, which is why settings are matched to your skin tone and goals at consultation. Richer skin tones are treated more conservatively to reduce the risk of temporary post-inflammatory pigmentation.

The clinic’s doctors assess your skin and apply numbing cream for about 30 to 45 minutes before treatment to keep the session comfortable.
Energy, density, and depth (3 adjustable settings) are chosen for your concern and skin tone, since scar resurfacing uses stronger settings than light rejuvenation.
The 10,600 nm beam creates a grid of microscopic columns across the area, with a typical face session taking about 15 to 30 minutes.
Redness, swelling, and flaking are expected for several days, with new surface skin usually forming over about 7 days.
Collagen rebuilds for several months, so most patients complete 2 to 3 sessions spaced 4 to 8 weeks apart for scars and texture.

The clinic’s doctors assess your skin type, scar depth, and goals, then explain settings and downtime in English at our Gangnam (Seoul) location.
After about 30 to 45 minutes of numbing, the laser session itself typically takes around 15 to 30 minutes for a full face.
Most scar and texture plans run as 2 to 3 sessions spaced 4 to 8 weeks apart rather than a single visit.
New surface skin forms over about 7 days, and collagen remodelling continues for several months, so improvement builds gradually.
Strict sun protection and gentle care protect results; benefits can last well, though maintenance may be advised as skin continues to age.
CO2 laser treats atrophic acne scars, rough texture, enlarged-looking pores, and fine wrinkles by resurfacing microscopic columns of skin at 10,600 nm. It is one of the stronger resurfacing tools, matched to your concern at consultation. You can explore related options on our laser treatment page.
At our Gangnam (Seoul) location, Dr. Yoongon Ryu leads CO2 laser consultations in English, and care is also available at our Myeongdong and Incheon Airport locations. Gangnam sits near Gangnam Station, convenient for international patients. A consultation confirms your candidacy, the right settings, and expected downtime before treatment.
CO2 laser is ablative, meaning it vaporises surface tissue at 10,600 nm for stronger resurfacing than non-ablative options, with more downtime in return. Er:YAG is more superficial, and RF microneedling heats the dermis via needles. Your doctor recommends the best fit; you can compare methods on our laser treatment page.
Numbing cream is applied for about 30 to 45 minutes beforehand, so most patients tolerate CO2 laser well, feeling heat and prickling during the pass. Afterwards the skin feels warm, like sunburn, for a day or so. Your doctor can adjust settings and comfort measures based on the area and your tolerance.
Expect several days of redness, swelling, and flaking as new surface skin forms, usually over about 7 days. Deeper scar-resurfacing settings extend recovery, while lighter rejuvenation heals faster. Diligent moisturising and sun protection support healing. Your doctor gives you a personalised aftercare plan and realistic downtime for the settings used.
Most patients need about 2 to 3 sessions spaced 4 to 8 weeks apart for scars and texture, though a single lighter session may suit mild rejuvenation. The exact number depends on your concern, skin type, and response. Your doctor reviews progress between sessions and adjusts the plan and settings accordingly.
You may notice smoother, fresher skin once the surface heals over about 7 to 14 days, but the main improvement builds over 3 months or more as collagen remodels. Scars and texture continue to refine across the series. Your doctor reviews progress so the plan stays matched to how your skin responds.
Collagen and texture improvements can last well, with photoaging benefits reported up to 5 years in studies, though skin keeps ageing, so results are lasting rather than a one-time fix. Sun protection and a good routine preserve them, and occasional maintenance may be advised depending on your skin and goals.
CO2 laser can be performed on Asian and richer skin tones when settings are chosen carefully, since aggressive resurfacing raises the risk of temporary post-inflammatory pigmentation. Your doctor uses more conservative energy and density and stresses sun protection. A consultation assesses your skin tone so treatment is matched safely to reduce pigmentation risk.
Yes, CO2 laser is often part of a broader plan, for example alongside subcision for tethered scars or supportive skin boosters for recovery and glow. A Rejuran Healer treatment can support skin quality between sessions. Your doctor sequences treatments so the skin is not over-stressed and healing stays on track.
Adults with atrophic acne scars, rough or sun-damaged texture, or fine wrinkles who can accommodate a few days of downtime are typical candidates. Very reactive skin, recent isotretinoin use, or a keloid history need careful review. A consultation grades your skin and confirms whether CO2 laser or a gentler option fits you best.
Gentle cleansing, generous moisturising, and strict broad-spectrum sunscreen are essential while the skin re-epithelialises over about a week, and picking flakes must be avoided. Your doctor may recommend soothing products. A supportive skin care routine protects healing skin and helps you get the most from each CO2 laser session.
For deeper atrophic scars, ablative fractional CO2 laser usually delivers stronger remodelling than a superficial peel, though it involves more downtime, so it is not automatically the right pick for everyone. Milder concerns may suit gentler options. Your doctor weighs your scar depth, skin tone, and downtime tolerance to recommend the most suitable approach.
Because CO2 laser flakes and reddens for several days, staying about 5 to 7 days lets you have the treatment and pass the most visible healing before flying. A consultation and one session can be arranged early in your trip. Our English-speaking team helps coordinate timing around your travel and any follow-up.
Flying a day or two after CO2 laser is possible, but the skin is still healing and flaking, so cabin dryness and sun through windows need managing with moisturiser and protection. Many international patients prefer to let redness settle first. Your doctor advises travel-friendly aftercare based on the settings you had.
International patients can complete a CO2 laser course across one or more visits, and the clinic offers remote check-ins in English between trips so recovery and planning stay on track. Your treatment notes are kept on file for continuity, and continuing supportive skin care at home helps maintain results.
