Scar Subcision in Seoul: Release Deep, Tethered Acne Scars
The short answer
Scar subcision releases the fibrous bands that pull rolling acne scars downward, using a fine needle or cannula under local anaesthesia so the skin can lift. In Gangnam a session typically costs ₩100,000–₩600,000 depending on the area. Bruising and swelling usually last five to ten days. Most patients need one to three sessions, often combined with laser or boosters.
Key facts
- Best for: rolling and tethered atrophic acne scars
- Method: needle or cannula releases fibrous bands under the scar
- Anaesthesia: local injection plus numbing cream
- Downtime: 5–10 days of bruising and swelling
- Sessions: usually 1–3
- Typical Seoul price: ₩100,000–₩600,000 per session
What subcision does
Some acne scars are depressed not because tissue is missing on the surface, but because fibrous bands underneath tether the skin downward. These scars often look like soft, rolling dips and become more visible in side lighting. Lasers alone struggle to lift them, because the bands keep pulling.
Subcision addresses the cause directly. A fine needle or blunt cannula is inserted under the skin and moved back and forth to cut the bands. Once released, the skin can rise, and the small amount of controlled bleeding stimulates new collagen in the space.
Which scars respond
| Scar type | Subcision benefit |
|---|---|
| Rolling scars | Excellent; the main indication |
| Shallow boxcar scars | Moderate; usually combined with laser |
| Icepick scars | Limited; need TCA CROSS or punch methods |
| Raised scars | Not suitable |
A simple test: if a scar softens or flattens when you gently stretch the skin, it is likely to respond to subcision.
What the procedure is like
After numbing cream, the doctor injects local anaesthetic into the scarred areas. A needle or cannula is then inserted through a tiny entry point. You may hear or feel a slight snapping as bands are released, but it should not be painful. Treatment takes 20–45 minutes depending on the number of areas. Some clinics place a small amount of filler or a booster under the released scars to keep them lifted.
Recovery
- Bruising and swelling for five to ten days, sometimes longer
- Tenderness and small entry marks that heal quickly
- Cold compresses help in the first 48 hours
- Avoid alcohol, saunas and intense exercise for a few days
- Avoid makeup on entry points for 24 hours
Combining subcision with other treatments
Subcision is rarely the only step. A common Seoul sequence is subcision followed by fractional laser, RF microneedling or boosters a few weeks later, so the surface and depth improve together. Our acne scar laser page and the scar remodeling guide explain these combinations. For practical clinic comparisons, see where to get acne scar treatment in Seoul.
Results
Some improvement is visible once swelling settles, and collagen continues to fill the released area over two to three months. Many patients see a meaningful difference after one session, with one or two more for deeper scars. Bands can partly reform, which is why repeat sessions are sometimes needed.
Risks
Bruising is expected. Less commonly, small lumps can form under the skin and usually soften over weeks. Infection is rare with sterile technique. Tell your doctor about blood thinners and any history of keloid scarring.
Planning as a visitor
Plan subcision at the start of a longer stay, as bruising can be visible for a week or more. If you are also having laser, ask how the clinic sequences treatments within your timeframe.
