What should you know about types of atrophic scars?

Ice-pick scars are narrow openings that extend more deeply into the skin. Boxcar scars are broader depressions with defined, often sharp edges. Rolling scars have wider, softer dips created when bands beneath the skin pull the surface downward. A person can have more than one type in the same area. Acne is a frequent cause, while chickenpox and other injuries can also leave depressed scars. These scars are different from raised scars, which project above the surrounding skin.

Treatment starts with controlling active acne or inflammation so new scars are less likely to form. A dermatologist assesses scar depth, edges, skin colour, location, and tendency to heal with pigment changes. Microneedling can create controlled skin stimulation, while laser treatment can resurface selected scars. Subcision releases fibrous bands under rolling scars, and dermal fillers may lift some individual depressions. The right approach may combine methods and usually requires staged care rather than one universal procedure.

Seek assessment if a depression is new, painful, crusted, bleeding, or changing rather than behaving like an old scar. Arrange care for active acne that is leaving new marks, or if scarring is affecting confidence and daily life. A clinician can separate scar tissue from an ongoing skin condition before treatment begins.

Ask which scar types are present, whether acne needs treatment first, which procedure targets each depth, what skin reactions are possible, and how aftercare may affect the result.
