CO2 Fractional Laser in Seoul (Hongdae): Scar and Texture Resurfacing
CO2 fractional laser is a resurfacing treatment that makes tiny columns of controlled injury in the skin to trigger new collagen, improving acne scars, wrinkles, enlarged pores and rough texture. At KLEAM Clinic Hongdae it takes about 20 to 45 minutes after numbing, with roughly 3 to 7 days of redness and peeling. It suits visitors who can plan for recovery time.

How it works
A CO2 laser vaporizes microscopic columns of skin while leaving the surrounding tissue intact. These small wounds heal quickly because healthy skin around each column helps repair them, and the healing process stimulates fresh collagen and elastin.
After numbing cream, you will feel heat and prickling during the treatment. Afterwards, the skin feels like a sunburn and looks red; over the next days it darkens slightly and flakes off, revealing smoother skin underneath. Collagen remodeling continues for months, so results keep improving.
Because it is a stronger laser, settings are chosen carefully for your skin type. For darker skin tones the doctor may use lower density to reduce the risk of temporary pigmentation.
How it compares
| Compared with | Difference |
|---|---|
| Fraxel | Non-ablative Fraxel has shorter downtime but usually needs more sessions, while CO2 fractional is stronger per session with more recovery time. |
| Microneedling | Microneedling is gentler with 1–2 days of redness, while CO2 fractional resurfaces more deeply for scars and texture. |

Frequently asked questions
How much downtime should I expect?
Most people have redness, swelling and peeling for about 3–7 days, depending on the strength used. The redness may fade more slowly, sometimes over a few weeks. Many visitors plan their treatment at the start of their trip so the peeling stage is over before they fly home.
Does CO2 laser hurt?
Numbing cream is applied for about 30–40 minutes before treatment. You will still feel heat and prickling, but most people find it manageable. Afterwards the skin feels like a sunburn for a day or two, and cooling helps. If you have any questions before booking, message us on WhatsApp or KakaoTalk and our English-speaking staff will help.
How many sessions do I need for acne scars?
Mild texture may improve after one session, while deeper acne scars usually need 2–3 sessions spaced 6–8 weeks apart. Combining CO2 with subcision, boosters or other treatments is common. The doctor will suggest a plan after examining your scars. If you have any questions before booking, message us on WhatsApp or KakaoTalk and our English-speaking staff will help.
Can I fly after CO2 fractional laser?
Flying is not harmful to the healing skin, but cabin air is very dry and the skin may still look red and flaky. Ideally allow a few days before your flight, keep the skin moisturized and avoid touching it during the trip.
Is it safe for Asian or darker skin?
It can be used, but there is a higher risk of post-inflammatory hyperpigmentation. The doctor adjusts energy and density, and strict sun protection afterwards is essential. If pigmentation appears, it is usually temporary and can be treated. If you have any questions before booking, message us on WhatsApp or KakaoTalk and our English-speaking staff will help.
How much does CO2 fractional laser cost?
The price depends on the area and treatment intensity. Please send your photos and concern on WhatsApp or KakaoTalk, and our staff will share current prices before your visit. Results and suitability vary from person to person, so the doctor confirms the best plan during your consultation.

CO2 Fractional Laser in Hongdae – Resurface Skin & Smooth Scars
Ready to renew your skin and erase stubborn scars or wrinkles? CO2 fractional laser treatment is a powerful, skin-resurfacing solution that targets deep skin imperfections—revealing smoother, clearer, and more youthful skin. At our clinic in Hongdae, we use advanced fractional CO2 laser technology to safely treat acne scars, large pores, fine lines, and uneven skin texture with precision and care.
What is CO2 Fractional Laser?
The CO2 fractional laser is a non-surgical skin rejuvenation treatment that uses a carbon dioxide (CO2) laser to create controlled micro-injuries in the skin. These tiny laser columns stimulate the body’s natural healing process, promoting new collagen production and skin regeneration—while leaving surrounding tissue intact for faster healing.
It effectively treats:
- Acne scars and surgical scars
- Wrinkles and fine lines
- Sun damage and age spots
- Enlarged pores
- Rough or uneven texture
- Stretch marks
Why Choose CO2 Fractional Laser?
Key Benefits:
✅ Dramatic skin resurfacing and scar reduction
✅ Tightens skin and smooths fine lines
✅ Evens out tone and reduces pigmentation
✅ Boosts collagen for long-term skin renewal
✅ Customizable intensity for different skin concerns
✅ Long-lasting results after just 1–3 sessions
How Does It Work?
The CO2 laser delivers microscopic beams of light into the skin, targeting both the outer (epidermis) and deeper (dermis) layers. This controlled injury triggers a powerful healing response, encouraging fresh skin growth and collagen remodeling.
Fractional technology means only a portion of the skin is treated at a time—allowing for quicker recovery and reduced risk compared to traditional full-field CO2 lasers.
What to Expect During Treatment
- Pre-Treatment Prep:
Your skin is cleansed, and a numbing cream is applied for comfort. - Laser Application:
The procedure takes about 20–45 minutes, depending on the treatment area and intensity. - Aftercare:
Redness, swelling, and peeling are normal for 3–7 days. Skin will feel tight or sunburned immediately after. Strict sun avoidance and moisturizing are critical during healing.
You may also receive post-care products or a recovery kit to support skin renewal.
Who is a Good Candidate for CO2 Laser?
This treatment is ideal for:
- Adults with acne scars, wrinkles, or rough skin
- Individuals with sun damage or enlarged pores
- Those seeking dramatic skin texture improvement
- Patients who can commit to downtime and post-treatment care
It may not be suitable for those with active acne, very dark skin tones, or certain skin conditions. A consultation is required to assess suitability.
When Will You See Results?
Initial results can appear after 1–2 weeks, with continued improvements in skin tone and texture over the next 1–3 months as collagen rebuilds. For deeper scarring or wrinkles, 2–3 sessions spaced 6–8 weeks apart are often recommended.
Results can last for years with good skincare and sun protection.
