Acne Scar Laser in Seoul
The short answer

Acne scar laser treatment smooths depressed scars by resurfacing the skin and triggering new collagen with fractional CO2, erbium or RF microneedling. In Gangnam a session typically costs ₩150,000–₩600,000, and most patients need three to six sessions four to six weeks apart. Expect five to seven days of redness and fine scabbing; scars typically improve by 30–60%, not disappear.

How laser improves acne scars

Depressed acne scars form when inflammation destroys collagen and the skin heals with a dip. Fractional lasers create thousands of microscopic treatment zones in the skin, leaving healthy skin in between. The body repairs each zone with new collagen, which gradually lifts and smooths the scarred areas. Lasers do not erase scars completely, but a series of sessions can make them much less noticeable.

Scar types and what works

Scar type Description Main approach
Rolling Wide, soft undulations Subcision plus laser or RF microneedling
Boxcar Defined edges, flat base Fractional CO2 or erbium, TCA CROSS
Icepick Narrow, deep pits TCA CROSS or punch techniques plus laser
Hypertrophic Raised Injections, vascular laser

Most people have a mix of types, so combination treatment usually gives the best result. Our guide to acne scar combination treatments in Gangnam explains how clinics layer techniques.

The main laser options

Fractional CO2

The strongest common option for textured scars. It removes and heats tiny columns of tissue, producing a robust collagen response with about a week of downtime. See our CO2 laser resurfacing page.

Fractional erbium (Er:YAG)

Similar principle with less heat spread, which can mean slightly faster recovery and lower pigment risk in some skin types.

RF microneedling

Needles deliver radiofrequency into the dermis with minimal surface damage. It suits darker skin and patients who want less downtime.

What a session is like

Numbing cream is applied for 40–60 minutes. The laser feels hot and prickly, and the treatment itself takes 20–40 minutes. Cooling and a soothing mask follow. Your skin will look red and slightly swollen when you leave.

Recovery

  • Days 1–2: redness and swelling, like a strong sunburn
  • Days 3–5: fine dark scabs or bronzing that flake off
  • Day 7: most people are presentable with makeup
  • Pinkness can last two to four weeks

Use the prescribed ointment, avoid makeup until the clinic allows it, and protect your skin from sun. Post-inflammatory darkening is the main risk in Asian and darker skin, which is why sunscreen and gentle care matter.

Results

Improvement continues for three to six months after each session as collagen matures. Most patients see about 30–60% improvement after a full course. Deep scars need more sessions and combined techniques.

Planning as a visitor

Because of the one-week recovery and four to six week intervals, acne scar laser suits longer stays or repeat visits. Book the session at the start of your trip and plan quieter days afterwards. If you want minimal downtime, ask about RF microneedling. For clinic options, see top acne scar treatment clinics in Gangnam.
