Acne Scar Treatment in Seoul – Diagnosis by Board-Certified Dermatologists
Acne scars are permanent changes in skin texture left after inflammatory acne, including rolling, boxcar and ice-pick depressions and, less often, raised scars. At The Heal Dermatology Sinsa Main Branch in Gangnam, Seoul, board-certified dermatologists classify each scar type and combine subcision, fractional or microneedle RF and collagen stimulators to gradually improve texture.

What causes acne scars
Scars form when deep inflammation damages collagen during healing. Cystic acne, delayed treatment and picking raise the risk, and genetics influence how skin heals. Atrophic (depressed) scars are most common on the face, while raised scars and keloids are more frequent on the chest and back.
How a dermatologist diagnoses it
A dermatologist examines scars under angled light and uses imaging-based skin analysis to classify them as rolling, boxcar or ice-pick, and to separate true scars from flat post-inflammatory marks. Active acne should be controlled before scar treatment begins.
Treatment options at The Heal Sinsa
Most people need a combination. Subcision releases tethered rolling scars, Potenza microneedle RF or fractional laser remodels texture, and Juvelook or Rejuran supports collagen. Availability of specific devices varies by branch – confirm at consultation. Every plan starts with a 1:1 consultation with a Korean board-certified dermatologist and imaging-based skin analysis; you will not be pushed toward treatment you do not need. Pricing is confirmed after consultation; see pricing and payment.
Sessions, downtime & side effects
- Typically three to five sessions, about 4–6 weeks apart
- Redness and swelling for a few days; fractional laser may cause about 5–7 days of crusting
- Improvement is gradual over months, not complete removal
- Avoid during active infection, pregnancy or recent isotretinoin use without dermatologist advice
Home care
Keep active acne under control, use sunscreen daily to prevent marks darkening, and follow aftercare carefully between sessions. Avoid picking and harsh scrubs, and use gentle moisturisers that support healing.
When to see a doctor
See a dermatologist as soon as acne leaves marks or pits; earlier acne control prevents new scars. Seek advice promptly if scars become raised, itchy or painful, which can suggest keloid tendency.
Planning around your trip to Seoul
Fractional treatments can leave visible redness, so leave a few days before flights or photos; our downtime guide helps with planning. The clinic is on the 7th floor of Sinsa Square near Sinsa Station, close to Garosu-gil (getting here), and English support is available on request (international patients).

Frequently asked questions
Can acne scars be removed completely?
Complete removal is rarely possible, but most people can achieve meaningful improvement in depth and texture with a series of combined treatments. Your dermatologist will set realistic expectations based on scar type and your skin.
How many sessions do acne scars need?
Many people need three to five sessions spaced about four to six weeks apart, sometimes more for deep scars. Results continue to improve for several months after each session as new collagen forms.
Can I treat scars while I still have acne?
Active acne is usually treated first, because inflammation can worsen with some procedures and new spots can create new scars. Some gentle treatments may be combined; your dermatologist will decide the safest order.
