Acne scarring is one of the most frequently searched skin concerns — and one where mismatched treatment causes the most disappointment, because “acne scarring” actually covers several genuinely different types of scar, each responding to different approaches.

The main types, briefly

Rolling scars create a wave-like unevenness in the skin’s surface, caused by fibrous bands pulling the skin down from beneath. Boxcar scars are broader, more defined depressions with sharper edges. Ice pick scars are narrow, deep, and pointed. Each of these responds differently to treatment — which is exactly why a generic “acne scar treatment” often underdelivers.

What tends to help which type

Rolling scars often respond well to treatments that address the fibrous bands beneath the surface, alongside regenerative treatments like polynucleotides that support the skin’s own repair processes. Boxcar and ice pick scars, being more structurally defined, often need a more targeted approach, sometimes including subcision or resurfacing treatments planned specifically around the scar’s depth and shape.

Why patience matters more here than almost anywhere else

Scar tissue is genuinely slower to respond than most other skin concerns — meaningful improvement is usually measured in months and multiple sessions, not one appointment. This is an area where realistic expectations, set clearly at the outset, matter more than almost any other treatment we discuss.

The honest starting point

Because the right approach depends entirely on scar type — and most people have a mix of more than one — this is a case where an in-person assessment genuinely changes the plan, rather than being a formality before booking whatever was already decided online.
