How it works
Acne scars form when inflammation damages collagen deep in the skin. Indented scars sit below the surface, sometimes tethered by fibrous bands, while red or brown marks are discoloration rather than true scars.
Fractional CO2 laser creates tiny columns of controlled injury that trigger collagen remodeling. Microneedling does something similar mechanically. Subcision releases fibrous bands pulling scars down, PRP supports healing, and fillers can lift deeper scars temporarily. Laser toning and peels target leftover discoloration.
Because scars differ even on one face, combining methods usually works better than one treatment alone. Improvement is gradual and depends on scar depth, skin type and the number of sessions.
How it compares
| Compared with | Difference |
|---|---|
| Fractional CO2 laser vs microneedling | CO2 laser is stronger with more downtime, while microneedling is gentler with less downtime but may need more sessions. |

Frequently asked questions
Can acne scars be completely removed?
Most acne scars can be significantly improved but rarely removed completely. A combination of treatments usually works best. The doctor explains what level of improvement is realistic for your scar type. Every plan starts with a doctor consultation, and results vary from person to person, so the doctor explains what is realistic for you before treatment.
How much does acne scar treatment cost in Seoul?
Cost depends on the methods used, the area and the number of sessions. We confirm pricing after consultation. You can send photos on WhatsApp to get an initial estimate. Prices are quoted in Korean won, and the doctor explains exactly what is included before any treatment begins, so there are no surprises on the day.
How long is the downtime?
Fractional CO2 laser and subcision usually cause about 3–7 days of redness, swelling or peeling. Microneedling and laser toning have minimal downtime. The doctor can adjust the plan to your trip. If you have an important event or photos planned, tell the doctor so the treatment strength and timing can be adjusted to your schedule.
How many sessions will I need?
Many people see improvement after 2–3 sessions, with 4–6 sessions often needed for optimal results. Sessions are usually spaced several weeks apart, so international patients often plan treatment over multiple trips. Results vary between individuals, so the doctor reviews your progress at each visit and adjusts the plan as needed.
Can I fly after fractional laser?
Yes, flying is generally fine, but cabin air is dry, so keep the skin moisturized. It is best to schedule laser early in your trip so the doctor can check healing before you leave. If you have any concerns after you get home, you can message our English-speaking team on WhatsApp with photos and we will advise you.
Should I treat active acne first?
Yes. Active acne should be controlled before scar treatment, because new breakouts can create new scars. The doctor may start with acne care before moving on to scar treatment. Every plan starts with a doctor consultation, and results vary from person to person, so the doctor explains what is realistic for you before treatment.

Acne Scar Removal in Hongdae – Smooth Skin & Restore Confidence
Frustrated by lingering acne scars that won’t fade no matter what you try? Whether you’re dealing with icepick scars, boxcar depressions, or post-acne pigmentation, our clinic in Hongdae offers advanced acne scar removal treatments that help smooth skin texture, even out tone, and rebuild confidence—without invasive surgery.
What Are Acne Scars?
Acne scars form when inflamed blemishes damage the deeper layers of the skin. The body tries to repair this damage by producing collagen, but when it produces too little or too much, scars form. Common types of acne scars include:
- Atrophic Scars (indented): icepick, boxcar, rolling
- Hypertrophic/Keloid Scars (raised): thick, overgrown scars
- Post-inflammatory Hyperpigmentation (PIH): flat dark marks left after acne heals
Scars can become more visible over time if left untreated, especially with sun exposure or skin thinning.

Key Benefits of Professional Treatment:
✅ Smooths uneven skin texture
✅ Stimulates collagen regeneration
✅ Reduces redness, discoloration, and scar depth

✅ Long-term skin renewal and confidence boost
Acne Scar Removal Treatments Offered
Our Hongdae clinic provides a full suite of cutting-edge treatments for various scar types:
- Fractional CO2 Laser
A powerful skin-resurfacing tool that breaks down scar tissue and stimulates deep collagen renewal. - Microneedling / MTS
Minimally invasive technique that promotes smoother skin and improves the appearance of scars over time. - Subcision
Targets deep, tethered scars by releasing the fibrotic strands beneath the skin surface. - PRP (Platelet-Rich Plasma)
Enhances microneedling or laser results by using your own growth factors to accelerate healing and tissue regeneration. - Chemical Peels (TCA, Jessner’s)
Gently exfoliate and resurface the skin to lighten pigmentation and smooth shallow scars. - Dermal Fillers
Temporarily lift depressed scars for a smoother skin surface—ideal for deep boxcar or rolling scars. - Laser Toning (for PIH)
Targets melanin to fade brown or red acne marks and even out skin tone.
What to Expect During Treatment
Treatment choice depends on your scar type, skin sensitivity, and goals. Most sessions last 30–60 minutes, with minimal discomfort. Numbing cream is applied when necessary.
Downtime varies: fractional laser and subcision may involve redness and peeling for 3–7 days, while microneedling and toning have little to no downtime.
Your provider will guide you on post-care, including gentle cleansing, sun protection, and hydrating products to optimize healing.

You may benefit from acne scar removal if:
- You have visible pitted, raised, or discolored acne scars
- Over-the-counter products haven’t worked
- You want to improve skin texture and radiance
