Subcision for Acne Scars in Gangnam

How it works

Subcision is a minor procedure for depressed scars, particularly rolling acne scars. After local anaesthetic, the doctor inserts a fine needle or blunt cannula under the scar and moves it gently to release the fibrous bands that tether the scar down to deeper tissue. Once released, the skin can lift, and controlled healing builds new collagen under the area. Subcision is often combined with other treatments, such as fractional lasers, microneedling radiofrequency, or collagen-stimulating injectables, for better overall results.

Who it's for

It is typically suited to adults with rolling or some boxcar acne scars, or other tethered depressed scars. Ice-pick scars usually respond better to other techniques. Active acne should generally be controlled first. Raised scars such as keloids and hypertrophic scars are not treated with subcision.

Anaesthesia: local anaesthetic injection or numbing

Risks & who should avoid

Common effects include bruising, swelling and tenderness. Less commonly, lumps, infection, or post-inflammatory hyperpigmentation can occur. Results vary, and scars are usually improved rather than removed. Subcision is generally avoided during pregnancy, with active acne or infection in the area, bleeding disorders, or a tendency to keloids. Tell the doctor about blood thinners and recent isotretinoin use.

Planning around your trip to Seoul

Because bruising can last a week or more, plan subcision at the start of a longer stay and avoid important photos soon after. See the downtime guide. See international patients and getting here for practical details.

Which acne scars respond to subcision?

Rolling scars, which look like soft undulations, usually respond well because they are tethered by fibrous bands. Some boxcar scars also improve. Narrow ice-pick scars generally need other techniques, so most people benefit from a combined plan.

How long is the downtime after subcision?

Bruising and swelling are common and typically last around five to ten days, depending on the area treated and your skin. Most people can return to desk work within a day or two, using concealer once small entry points have closed.

How many subcision sessions will I need?

Many people need one to three sessions spaced several weeks apart, often alongside lasers or other treatments. The number depends on scar depth, type and how your skin responds. The dermatologist reviews progress before each session.
