Acne Scar Types: Rolling, Boxcar and Icepick

Short answer: there are three main atrophic acne scar types. Rolling scars are wide and wave-like; boxcar scars have sharp edges and flat bases; icepick scars are narrow and deep. Each responds to different methods, which is why most plans combine several.

1. Rolling scars

Caused by fibrous bands tethering skin downward. Best treated by releasing the bands (subcision) and rebuilding with collagen boosters such as Juvelook.

2. Boxcar scars

Box-shaped depressions. Fractional CO2 and microneedle RF (Secret RF, Potenza) remodel the edges and base.

3. Icepick scars

Narrow and deep. They need focused techniques targeted at each scar.

4. Why combination works

Most faces have mixed scars. The Scar Renewal Technique maps each type, then layers treatments over 3–5 sessions.

5. Realistic expectations

A 50–70% improvement over a full course is a typical goal. Can scars be removed completely?

Conclusion
