Acne scars: the types, and how dermatologists treat each one
Rolling, boxcar or ice-pick? Knowing your scar type explains why one treatment rarely fixes everything.

Acne scars are the reminder of breakouts long gone. The good news is that almost everyone's scars can improve; the key is matching the treatment to the scar.
Marks are not scars
Flat brown or red spots after acne are pigmentation, not scars. They fade with time, sunscreen and treatments like peels. True scars change the skin's surface, leaving dips or raised areas.
The three common types
- Rolling scars: wide, soft dips that give skin a wavy look, caused by bands pulling the surface down.
- Boxcar scars: round or oval dips with sharp edges, like small craters.
- Ice-pick scars: narrow, deep scars that look like large open pores.
How each is treated
Rolling scars often respond to subcision, which releases the bands, followed by collagen-building treatments. Boxcar scars respond well to fractional lasers and microneedling radiofrequency. Ice-pick scars may need targeted techniques before resurfacing.
Why it takes time
Collagen rebuilds slowly, so treatments are spaced four to six weeks apart and results keep improving for months after the last session. Active acne needs to be under control first, or new scars will form.
What to expect
Most people see a clear improvement in depth and texture over a course. A dermatologist will set realistic expectations after examining your scars in person.
