Ice-pick scar is the term for a narrow, deep, pit-like acne scar, usually under about 2 mm across, that tapers down into the dermis like the mark of an ice pick. Ice-pick scars are often mistaken for large pores. Resurfacing alone barely changes them because it polishes the skin around the pit, so they are treated focally: the treatment has to reach the floor of the tract, not just the surrounding surface.
Ice-pick scars are the deepest and narrowest of the three atrophic acne scar shapes, and the one most often left behind after a course of resurfacing that improved everything else. Dr Sin Yong treats them at the base: TCA CROSS places a tiny amount of high-strength trichloroacetic acid into each scar floor to prompt the tract to rebuild from within, and fractional CO₂ then refines the surrounding texture, usually after the focal steps. The full account is on the ice pick scars treatment page, and the scar sits within the wider plan on the acne scar treatment guide. Active acne is controlled before any scar is treated.
No, though they are often mistaken for them. An enlarged pore is a widened follicle opening; an ice-pick scar is a narrow tract of lost tissue that goes deeper into the dermis. Pore treatments do not change an ice-pick scar.
Rarely well. Resurfacing remodels the skin around a pit but barely changes the depth of a narrow tract. TCA CROSS treats the floor first; fractional CO₂ refines the surrounding skin afterwards.
