CO2 laser is an ablative laser that emits light at 10,600 nm, a wavelength strongly absorbed by water in the skin. In Myeongdong, Seoul it is used both to precisely remove discrete lesions, such as moles, warts, and skin tags, and, in fractional mode, to resurface larger areas for acne scars, uneven texture, enlarged pores, and fine lines. Because it removes tissue rather than just heating it, CO2 laser is one of the more powerful resurfacing tools, which is why settings must be matched carefully to each person.
In fractional mode, the laser delivers energy in a grid of tiny microscopic columns, treating only a fraction of the skin’s surface at a time while leaving healthy tissue between the columns. That untreated skin speeds healing and helps drive collagen renewal, so the deeper layers remodel over the weeks and months after treatment. This is why resurfacing results build gradually and usually across a short series rather than appearing overnight.
At our Myeongdong (Seoul) location, 5, Myeongdong 10-gil, Jung-gu, CO2 laser is doctor-led and international-patient friendly. Dr. Seung Jae Baek, Medical Director, assesses your concern and Fitzpatrick skin type, then tailors depth, density, and session count and explains it all in English. The clinic is about 5 minutes from Myeongdong Station, with multilingual support for visitors to Seoul.
The CO2 laser produces infrared light at 10,600 nm that is absorbed by water inside skin cells, so the energy converts to heat and vaporises tissue with fine, controllable depth. In ablative full-field use, this precision lets a doctor remove a discrete lesion while sparing surrounding skin. In fractional mode, the beam is split into a matrix of microscopic treatment columns, each reaching into the dermis, surrounded by untouched skin that acts as a healing reservoir. This fractional pattern triggers a wound-healing cascade and new collagen and elastin formation, which is what smooths acne scars, refines pores, and improves texture over the following months. The doctor adjusts two key parameters, depth (how far the columns reach) and density (how much of the surface is treated), to match the concern and the skin type. Deeper Asian skin tones are treated with more conservative settings because pigment-change risk rises with intensity, so parameters are personalised rather than fixed. This controlled, tuneable ablation is the core of why CO2 laser is effective yet requires an experienced, individualised approach.

The doctor assesses your concern and Fitzpatrick skin type, then chooses between lesion removal and fractional resurfacing across the treatment area.
Topical anaesthetic is applied for about 20 to 30 minutes so the resurfacing or removal is comfortable during the session.
The 10,600 nm laser creates a grid of microscopic columns, treating a fraction of the surface while leaving healthy skin between columns to speed healing.
The controlled injury triggers new collagen over the following weeks, with texture and scar improvement building across 2 to 3 sessions for most people.
The skin flakes and settles over about 1 to 2 weeks, and the doctor reviews progress before planning any further session.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
Dr. Seung Jae Baek assesses your concern and skin type, then explains whether lesion removal or fractional resurfacing suits you, and the plan, in English.
After about 20 to 30 minutes of numbing, the session itself typically takes around 20 to 45 minutes depending on the area treated.
Resurfacing usually runs over 2 to 3 sessions spaced weeks apart, while a single lesion is often treated in 1 visit.
Skin flakes and settles over about 1 to 2 weeks, and texture and scar improvement continue building over the following months.
Strict sun protection and gentle skincare protect results; occasional maintenance may be planned as natural ageing continues over time.
CO2 laser is used to resurface skin for acne scars, uneven texture, enlarged pores, and fine lines, and to precisely remove lesions like moles, warts, and skin tags. It emits 10,600 nm ablative light absorbed by water in the skin. You can explore related options on our laser treatment page.
Fractional CO2 laser delivers energy in a grid of microscopic columns, treating only part of the skin surface while leaving healthy tissue between columns to speed healing. This controlled injury triggers new collagen over weeks, so scars and texture improve gradually. The doctor tailors depth and density to your concern and skin type.
Yes, ablative fractional CO2 laser is a well-studied option for atrophic acne scars, with Asian-skin studies showing over half of patients achieving above 50 percent improvement across sessions. Results build over months as collagen remodels. Active acne is usually settled first, which you can read about on our acne treatment page.
Discomfort is managed with topical numbing applied for about 20 to 30 minutes before treatment, so most people tolerate the session well. You may feel warmth or a prickling sensation during passes. Afterward the skin feels like a mild sunburn for a day or two, which your doctor helps you manage with aftercare.
Most patients experience redness, swelling, and flaking that settles over about 1 to 2 weeks, depending on the depth and area treated. A single small lesion heals faster than full-face resurfacing. Your doctor provides written English aftercare, and you can review the general laser treatment approach beforehand.
Resurfacing for scars or texture typically improves over 2 to 3 sessions spaced weeks apart, while a discrete lesion is often removed in a single visit. The exact number depends on your concern, skin type, and how you respond, which your doctor reviews between visits to keep the plan matched to your goals.
A treated lesion heals within 1 to 2 weeks, while resurfacing results build gradually over the following months as collagen remodels across sessions. Early smoothness appears once redness fades, then continues improving. Your doctor reviews progress between visits so each session is timed to how your skin is responding.
Results can hold for a long time, especially with diligent sun protection and skincare, though natural ageing continues over the years. Lesion removal is typically lasting once healed. Some patients plan occasional maintenance sessions, and a good skin care routine helps protect the improvement between treatments.
It can be, but darker Asian skin needs more conservative settings because post-inflammatory hyperpigmentation risk, reported in up to about 30 percent in some studies, rises with intensity. Your doctor personalises depth and density to your Fitzpatrick type. Careful technique and strict sun protection are central to keeping results even and safe.
Common, temporary effects include redness, swelling, flaking, and sensitivity as the skin heals over 1 to 2 weeks. Less commonly, pigment changes or, rarely, scarring can occur, which correct settings and aftercare help prevent. Your doctor discusses your specific risks at consultation and gives detailed instructions to lower the chance of complications.
Yes, CO2 laser is often part of a broader plan, sequenced safely by the doctor with pigment care, hydration, or booster treatments once the skin has healed. Combining is timed to avoid over-stressing the skin. A supportive skin care routine also protects and extends your resurfacing results.
Most adults with atrophic acne scars, uneven texture, enlarged pores, fine lines, or a discrete lesion are suitable candidates. A consultation assesses your concern and skin type and confirms the right settings. Recent isotretinoin use, a tendency to keloid, or active infection may need review first, which your doctor explains clearly.
Keep the skin clean and well moisturised, avoid picking any flaking, and use strict sun protection for several weeks to lower pigment-change risk. Your doctor provides written English instructions. A gentle daily skin care routine supports the barrier as new collagen forms and helps protect your results.
Our operating location for this care is Reberry Clinic in Myeongdong, at 5, Myeongdong 10-gil, Jung-gu, Seoul, about 5 minutes from Myeongdong Station. Dr. Seung Jae Baek performs the assessment and treatment. International patients receive English-language support, making it convenient for visitors staying in central Seoul to plan a consultation.
For a single lesion, 2 to 3 days is comfortable, allowing consultation, treatment, and a brief check. For resurfacing with visible flaking, many patients allow a few extra days so healing is well underway before flying. Our English-speaking team helps coordinate timing around your travel and any follow-up visits.
Yes, flying within a day or so is generally fine, though your skin may be red or flaking after resurfacing. Cabin air is drying, so moisturise well and protect treated skin from sun during travel. Your doctor advises on aftercare, especially if a larger area was resurfaced during your visit to Seoul.
International patients can complete a lesion removal in one visit, while a resurfacing course can be spread across trips, with remote English check-ins between visits. Your treatment notes are kept on file for continuity. You can continue supportive skin care at home to protect and build on your results.
