Permanent Acne Scars

Ice Pick Scars
These are permanent scars that look like deep pores with tapered bottoms, like a hole left by an ice pick.

Boxcar Scars
These types of scars are not as deep as ice pick scars. They are shallow depressions in the skin with raised borders.

Rolling Scars
Rolling scars create an uneven skin texture but are not as deep or discrete as other acne scars.
