Acne scarring: which treatment suits which scar
Icepick, boxcar and rolling scars respond to different modalities. Here is how specialists match treatment to scar type.
Not all acne scars are the same, and matching the modality to the scar type is the single biggest determinant of results.
Rolling scars, which are tethered below the surface, respond best to subcision followed by collagen stimulation. Boxcar scars often need resurfacing to soften their sharp edges. Icepick scars, which are narrow and deep, typically require focal treatment such as TCA CROSS.
Most people need a combination protocol across several sessions rather than a single treatment. Active acne should be controlled first, and daily sun protection is essential throughout.
