Concise answer
There is no single best procedure for every acne scar. The useful question is which method fits each scar type, skin type and recovery preference.
A patient may have ice-pick, boxcar and rolling scars together, with post-acne pigment adding further contrast.
Combination plans are common because one procedure cannot correct every layer.
When evaluation may help
Assessment is needed before resurfacing, needling, subcision or focal scar procedures are selected.
