Korean Acne Scar Treatments for Ice Pick, Boxcar and Rolling Scars

Why scar type determines treatment

Depressed acne scars form when inflammation damages collagen deep in the skin and the healing process leaves the surface lower than before. Dermatologists usually group these scars into three main shapes: ice pick, boxcar and rolling. Most people have a mix. Because each shape has a different structure, Korean clinics typically combine several methods rather than relying on one device. Knowing your scar types helps you understand why a doctor recommends a particular plan.

It also helps to separate true scars from marks. Flat red or brown spots left after a breakout are not depressed scars. They often fade with time, sun protection and, in some cases, toning. Depressed scars, by contrast, involve a change in the skin's structure, so they need treatments that remodel collagen or release tethering. A doctor's examination, ideally under angled lighting that shows shadows, makes the difference clear.

Ice pick scars

Ice pick scars are narrow, deep and sharply defined, like a small puncture in the skin. They often extend down into the deeper dermis.

Challenge. Their depth and narrow opening make them hard to reach with surface treatments alone.
Common approaches. Targeted techniques that focus on individual scars, sometimes followed by resurfacing. These are decided and quoted by the doctor at consultation.
Realistic outcome. They may become shallower and less noticeable, but complete flattening is uncommon.

Boxcar scars

Boxcar scars are wider depressions with sharp, vertical edges and a flatter base, sometimes described as looking like chickenpox scars.

Shallow boxcar. May respond to fractional laser or RF microneedling that smooths the edges and stimulates collagen.
Deep boxcar. Often needs combination treatment, as resurfacing alone may only soften the edges.
Common options. Fractional laser such as U-Pulse Fraxel and RF microneedling such as Potenza.

Rolling scars

Rolling scars are broad, gentle depressions that give the skin a wavy, uneven look, especially in side lighting. They are often caused by fibrous bands that tether the skin downwards.

Releasing tethering. A technique called subcision, which cuts these bands under the skin, is commonly discussed. The doctor decides if it is appropriate and quotes it at consultation.
Collagen stimulation. RF microneedling and fractional lasers are often added to improve the surface.
Volume support. In some cases, fillers or collagen stimulators are considered to lift deeper depressions. These are quoted after consultation because the amount of product varies. Fillers carry risks, including rare vascular complications, so this should be discussed carefully with a doctor.

Building a combination plan

Control active acne first. New breakouts create new scars, so treating acne comes before or alongside scar work.
Map your scars. The doctor identifies which areas are ice pick, boxcar or rolling.
Combine and space sessions. Different methods are spaced weeks apart to let the skin heal.
Protect from sun. Treated skin is more prone to pigment change.
Review progress. Collagen remodelling takes months, so progress is judged over time.

For visitors to Busan, a scar plan can start during a short stay, with the first session done after consultation and later sessions continued on a return trip or with a clinic at home. Payment is made at the clinic on the day, once the plan is confirmed. Side effects can include redness, swelling, bruising, temporary darkening and, rarely, infection or worsened scarring. Results vary and are not guaranteed.
