I think PRP itself is more of a marketing gimmick than it actually helping. Maybe it might help a bit if injected directly into the scars - but I haven't really seen any studies done on it. It also costs a few hundred bucks each time I think.

The dermaroller/dermapen can help to some extent depending on your type of scarring. I would personally just try 3-4 sessions with the normal dermapen and then see how it goes.

The type of scars I have look like dilated pores (I suppose icepick?) and have been slightly reduced with exfoliation and retinoids but they are still visible regardless.

PRP ,by itself not a treatment for acne scars but it help with healing ,because as i remember that it's contain growth factors that help with wound healing, i think dermapen is better than dermaroller if you have isolated scars cuz it will target every scar effectively

Personally speaking I wouldn't do any type of treatment for that - not worth the risks IMO. If it bugs you - retin a should help after a while, if not then you can explore fraxel re:store or dermarolling.
