CO2 Fractional Laser for Acne Scars: Results and Downtime

CO2 fractional laser is one of the most powerful non-surgical treatments for acne scars. It can make a significant difference to texture, but it also has more downtime than many other options. Here is what to know.

1. How CO2 fractional laser works

CO2 fractional laser creates tiny columns of controlled injury in the skin, leaving surrounding tissue intact. As the skin heals, it produces new collagen and smoother tissue, improving scar depth and texture.

2. Which scars respond?

Rolling scars, boxcar scars and general textural irregularities often respond well. Deep ice pick scars may need additional techniques. Your doctor will assess scar types before planning.

3. Results

Many patients see noticeable smoothing after one session, with further improvement over additional sessions. One to three sessions are typical. Collagen remodelling continues for months after each session.

4. Downtime

Expect about five to seven days of downtime with redness, swelling and fine crusting. After healing, the skin may remain pink for a few weeks. Plan treatment at the start of a longer stay or before time at home.

5. Aftercare

Keep skin moisturised and protected as directed.

Avoid picking crusts.

Use strict sun protection for several weeks.

Avoid make-up until the skin has healed.

6. Risks

Post-inflammatory pigmentation, prolonged redness and infection are possible. Settings must be adjusted for Asian skin to reduce pigmentation risk.

7. Cost in Seoul

At MIN Clinic, CO2 fractional laser typically costs around KRW 400,000 to KRW 1,000,000 per session. See our event price list.

8. Combining treatments

CO2 fractional laser is often combined with Juvelook, Potenza or subcision for deeper scars, and exosome to support recovery.

Conclusion

CO2 fractional laser offers strong improvement for acne scars over one to three sessions, with about five to seven days of downtime. Send photos of your scars to our English-speaking team on WhatsApp, or read more on our CO2 fractional laser page.
