Concise answer
Deep acne scars can often be improved, but complete removal is not a realistic promise. Mixed scar types frequently need staged combination treatment.
Narrow deep scars, sharp-edged depressions and tethered rolling scars respond to different techniques.
Active acne, skin type, downtime and pigment risk affect the sequence.
When evaluation may help
An in-person scar assessment can identify morphology and explain which scars are likely to respond to each approach.
