Which type of microneedling would be best for my loss of firmness, large pores and acne scarring?

Hi. My issues are loss of firmness, large pores and acne scaring (ice pick and some marks). Which microneedling would be best - RF (I do have fillers), PRP, or regular microneedling? I feel the providers I’ve seen tend to recommend the one they do. I’ve had several fraxel treatments which have not helped these issues. Thank you
