CO2 Fractional Laser

How it works

A CO2 laser removes thousands of tiny columns of skin while leaving the tissue between them intact. The body heals the columns over several days, producing new collagen and smoother texture over the following months. Deeper settings give more change and more downtime. Results vary by person, and darker skin carries a higher risk of lasting pigment change.

Who it may suit

• Moderate acne scarring, especially rolling and boxcar types
• Fine lines and rough texture
• Enlarged pores
• People who can plan about a week of visible recovery

The treatment day

1. Consultation. The doctor assesses scar type, skin tone, cold sore history, isotretinoin use and healing tendency before recommending depth.
2. Numbing. Numbing cream is applied and left on for a period, so the visit is longer than the laser time itself.
3. Laser treatment. The device is passed over the area with set depth and density. Heat and a prickling sensation are common.
4. Recovery guidance. Soothing products and written wound-care instructions are given, and a check visit is planned.

Aftercare

• Expect redness, swelling and crusting for about five to seven days
• Keep skin moist with the products advised and do not pick crusts
• Strict sun protection for weeks, with sunscreen once healed
• Avoid makeup until the doctor allows it
• Contact the clinic for severe pain, pus, spreading redness or blisters

Things to know first

• Prolonged redness, darkening of the skin and infection are possible
• Scarring, cold sore flare-ups and acne-like bumps can occur
• Not generally suitable around isotretinoin use, active infection, pregnancy or poor wound healing
• Darker skin tones face higher risk of lasting pigment change
• Improvement varies by person and often needs a series of sessions

What to check before booking CO2 fractional laser in Gangnam

Start with who chooses the depth and density. Those two settings largely decide both the improvement and the risk, and they should be tailored to your skin tone and scar type, not drawn from a preset program. A physician with dermatology training is well placed to recognise when your skin calls for a gentler approach. Ask directly who sets the parameters on the day.

Ask about your risk profile. A responsible doctor will ask about isotretinoin, cold sores, keloid tendency, recent sun and previous reactions, and will explain why those answers change the plan. If these questions are skipped, the consultation is incomplete. Ask also what the device is. The CO2 fractional laser appears under many labels, and the clinic should name the manufacturer and model it uses.

A clear quote covers the laser sessions, numbing, post-procedure products and follow-up. Be skeptical of descriptions that call the downtime a day or two when the usual range is about a week of crusting. Honest advice also notes that darker skin deserves extra caution and that you should plan the treatment away from important events and strong sun.
