Pico Laser vs Fractional CO2 Laser for Acne Scars
Both pico laser and fractional CO2 laser are used for acne scars, but they work very differently. One is gentle with minimal downtime; the other is powerful with a longer recovery. Here is how to choose.
1. How fractional CO2 works
Fractional CO2 removes tiny columns of skin and heats surrounding tissue, triggering strong collagen remodelling. It is one of the most effective lasers for textured scars.
2. How pico laser helps scars
In fractional mode, pico laser creates micro-injuries beneath the surface through photoacoustic effects, stimulating collagen with less surface damage. It also treats post-acne pigmentation.
3. Results compared
CO2 fractional: stronger improvement per session for deeper rolling and boxcar scars.
Pico laser: more gradual improvement, better for mild scars, texture and post-acne pigmentation.
4. Downtime compared
CO2 fractional laser typically involves five to seven days of downtime, with pinkness for a few weeks. Pico laser usually has mild redness for a few hours to a day.
5. Sessions
CO2 fractional: one to three sessions. Pico laser: more sessions are often needed for scars.
6. Asian skin considerations
Pico laser has a lower risk of post-inflammatory pigmentation. CO2 can be used safely with careful settings and aftercare.
7. Cost in Seoul
At MIN Clinic, CO2 fractional laser typically costs KRW 400,000 to KRW 1,000,000 per session, and pico laser KRW 200,000 to KRW 600,000. See our event price list.
Conclusion
Choose CO2 fractional for deeper textured scars if you can allow a week of downtime; choose pico laser for mild scars and pigmentation with minimal downtime. Send photos to our English-speaking team on WhatsApp, or read about acne scar removal.
