Are raised and indented acne scars treated the same way?

No. Scar shape affects treatment choice, and raised scars need a different assessment from indented scars. This is why scar assessment matters before choosing a device or protocol; 'acne scar' is not one single treatment category.

Raised and indented scars need different treatment plans

I would have them evaluated before choosing a procedure, particularly if you have a history of keloids. One treatment is not the answer for every scar.
