Pico Laser vs Fraxel: Which Is Better for Acne Scars?
Quick answer: Fraxel is usually better for moderate rolling and boxcar acne scars because its 1550 nm non-ablative fractional laser remodels collagen deeper, with 2–5 days of redness. Pico laser (pico fractional) is better for shallow scars, rough texture and scars mixed with dark marks, with less downtime and lower pigment risk. For deep or mixed scars, doctors in Seoul often combine treatments.
Which acne scar type do you have?
Before choosing pico laser vs Fraxel for acne scars, identify your scar pattern. Most people have a mix, and each type responds best to a different tool.
- Ice pick scars: narrow, deep pits. Lasers alone help little; targeted techniques are usually added.
- Boxcar scars: wider depressions with sharp edges. Fractional lasers such as Fraxel or CO2 often help.
- Rolling scars: soft, wave-like dips caused by tethering under the skin. Subcision combined with laser or RF microneedling is common.
- Texture and shallow scars: uneven surface and enlarged pores. Pico fractional and gentler options often suffice.
- Post-acne marks: flat brown or red marks are not true scars and usually respond to toning or vascular treatments.
A doctor examines your skin under angled light, because scars that look minor in a mirror can be deeper than they appear. Learn more on our acne scar removal in Seoul page.
How does pico laser treat acne scars?
Pico laser is a picosecond laser best known for pigment, but its fractional handpiece focuses energy into tiny points that create micro-injury pockets beneath an intact skin surface. The skin responds by producing new collagen and elastin while the surface stays mostly unbroken. See pico laser in Hongdae.
- Downtime: usually mild redness for 0–2 days.
- Bonus: it can fade brown post-acne marks at the same time.
- Limitation: deeper boxcar or rolling scars usually need something stronger or a combination.
How does Fraxel treat acne scars?
Fraxel is a non-ablative fractional laser at 1550 nm that creates thousands of microscopic heat columns in the dermis while leaving the outer layer intact. These columns trigger deeper collagen remodeling than pico fractional, which is why Fraxel is a long-standing option for moderate scars. Read about Fraxel laser in Seoul.
- Downtime: about 2–5 days of redness, swelling and a sandpaper-like feel.
- Strength: better for moderate boxcar and rolling scars than gentler lasers.
- Caution: more heat means more risk of temporary darkening on medium to deeper skin tones, so settings must be careful.
Pico laser vs Fraxel for acne scars: comparison table
| Factor | Pico fractional | Fraxel |
|---|---|---|
| Depth of effect | Superficial to mid | Deeper dermal remodeling |
| Best scar types | Shallow scars, texture, pigmented scars | Moderate boxcar and rolling scars |
| Downtime | 0–2 days | 2–5 days |
| Pigment risk on Asian skin | Lower | Moderate; needs careful settings |
| Typical sessions | Often 3–5 or more | Often 3–5, about 4 weeks apart |
| Typical Seoul cost (2026) | KRW 100,000–300,000 (about US$71–214) | KRW 150,000–400,000 (about US$107–286) |
How much does acne scar laser treatment cost in Seoul?
In Seoul in 2026, pico fractional typically costs about KRW 100,000–300,000 per session and Fraxel about KRW 150,000–400,000. A combination acne scar session (for example subcision plus laser) usually runs about KRW 150,000–500,000 (about US$107–357). Since scars need a series, multiply by the expected number of sessions.
What affects the price:
- Treatment area: full face vs cheeks or temples only.
- Laser passes and density, which the doctor adjusts to scar depth.
- Add-ons such as subcision, exosome or Rejuran for recovery.
- Package pricing for a multi-session course, and 10% VAT, usually added to cosmetic procedures.

Do you need more than a laser for acne scars?
Often, yes. Lasers resurface and remodel, but tethered rolling scars need the bands under the skin released, and deep scars may need stronger resurfacing. Common partners in Korea include:
- Subcision: releases tethered rolling scars before laser.
- RF microneedling (Potenza): combines needles and radiofrequency for scars and pores; see microneedling in Seoul.
- CO2 fractional: ablative and stronger, with about 5–7 days of downtime; see CO2 fractional laser.
- Skin boosters: Rejuran Healer or exosome to support healing and skin quality between sessions.
If you still get active breakouts, controlling acne first protects your investment; see acne care in Hongdae. For a deeper look at stronger lasers, read Fraxel vs CO2 Laser for Acne Scars.
Which is better for a short stay in Korea?
Pico fractional fits a short trip best: mild redness that usually settles within a day or two. Fraxel needs 2–5 days of social downtime, so book it near the start of a stay of at least a week and avoid it right before an important event or long-haul flight if you want to look camera-ready.
Neither laser finishes acne scar treatment in one visit. Many visitors do one or two sessions in Seoul and continue at home, or plan return trips about 4 weeks apart. Results build gradually over several months as collagen remodels.
Planning your visit to a skin clinic in Hongdae, Seoul
Hongdae is easy to reach: Hongik Univ. Station is on Line 2, the Gyeongui–Jungang Line and the AREX Airport Railroad, which runs directly to Incheon and Gimpo airports. A few tips help scar treatment fit a short trip.
- Ask for English- or Japanese-speaking staff when you book.
- Many clinics take consultations by WhatsApp or KakaoTalk; send close-up photos of your scars and your travel dates so downtime can be planned.
- Confirm who performs the treatment, the device, number of passes or shots, and whether 10% VAT is included.
- Check the current Hongdae clinic price list before you decide.
- Leave a buffer before your flight, especially after Fraxel.

Frequently asked questions
Is Fraxel or pico laser better for deep acne scars?
For deep scars, Fraxel is usually more effective than pico fractional because it remodels collagen deeper. Very deep or tethered scars often need subcision, RF microneedling or CO2 fractional as well. A doctor examines scar type and depth before recommending a single laser or a combination plan.
How many sessions do acne scars need?
Most people need a series, often 3–5 sessions about 4 weeks apart for Fraxel or pico fractional, and sometimes more for deeper scars. Improvement is gradual because new collagen forms over months. The doctor reviews progress between sessions and adjusts the plan.
Is pico laser safe for darker or Asian skin with acne scars?
Pico fractional is generally considered lower risk for post-inflammatory hyperpigmentation than heat-heavy lasers, which suits many Asian and medium skin tones. Fraxel can still be used with careful settings. Avoid tanning before treatment and use strict sun protection afterward.
Does Fraxel hurt?
Clinics usually apply numbing cream for about 30–40 minutes first. Most people feel heat and prickling during treatment, followed by a sunburn-like warmth for several hours. Pico fractional is usually milder. Cooling and soothing products help, and discomfort fades quickly.
Can I fly after Fraxel or pico laser?
Flying is usually fine after either, though Fraxel leaves 2–5 days of redness and swelling, so many people prefer a few days before a long flight. Keep skin moisturized on the plane, wear SPF, and avoid makeup on day one unless the doctor approves it.
