Subcision for Acne Scars

How it works

After local anesthesia, a fine needle or blunt cannula is inserted beneath the scar and moved to cut the fibrous bands pulling the skin down. Bleeding in the pocket and the healing response form new tissue that may lift the scar. It suits rolling scars more than icepick or deep boxcar types. Results vary, may continue to develop for weeks, and often need more than one session. It is commonly combined with other scar treatments at separate visits.

Who it may suit

• Rolling or tethered depressed acne scars
• Scars that look better when the skin is stretched
• People who understand that bruising is expected
• Visitors with a longer stay or the option to return

The treatment day

1. Scar assessment. The doctor stretches the skin and examines scar types, checks for active acne or infection, and reviews blood thinners and bruising tendencies.
2. Local anesthesia. Local anesthetic is injected under the scar area.
3. Release. A needle or cannula is moved under the scar to cut the bands. This takes about 20 to 40 minutes, with pressure and pulling sensations.
4. Pressure and dressing. Pressure is applied to limit bleeding, and a cold pack, dressing and instructions are given.

Aftercare

• Expect bruising and swelling for about 1 to 2 weeks, which may be worse in the first few days
• Apply cold packs briefly in the first day if advised, and avoid heat on the area
• Keep your head raised when resting and avoid pressing on the treated cheeks
• Avoid blood-thinning supplements and alcohol unless a doctor says they are safe
• Stay out of strong sun and keep the area clean until needle sites close

Things to know first

• Possible effects include bruising, swelling, pain, hematoma, infection, nodules, and uneven contour or overcorrection
• Results vary, are uncertain, and often need repeat sessions several weeks apart
• Not suited to active acne or infection in the area, bleeding disorders, or unpaused anticoagulants without medical guidance
• Icepick scars generally respond poorly to subcision alone
• Visible bruising can be hard to conceal, so it should not be scheduled just before key events

Planning subcision around a Seoul trip

This is a treatment for the first days of a longer stay, not a short break. Bruises on the cheeks can turn purple, then green and yellow, and may need up to two weeks to clear. Trip photos, business meetings and weddings should come after that window, or be avoided if the timing is tight.

Plan quiet time. Cold drinks, soft foods and a spare day with no heavy sightseeing can help while swelling is at its peak. Flying with a bruised face is possible but dry cabin air and seat positioning can be uncomfortable. If the doctor suggests more than one session, ask whether the second can be handled at home or whether you would need to return. Medications, supplements and bleeding history should be discussed before the day of treatment, not after.
