I am a 59yr fair skin woman, w/no acne scars. I'm torn between having a Fraxel or the RF Microneedling w/PRP. I know that I would need to have at least 3 Fraxels to see results. - My doctor is partial to the RFM & says I will need only one (1) RFM w/PRP treatment. However, I'm reading that I will need at least 3 FRM''s (w/PRP) to see results? I'm also reading that RFM is painful? Help!
