Profractional - with or without PRP?

I am considering have ProFractional done for large pores, uneven skin tone, fine wrinkles and a few brown spots. While it will be done in a dermatologist's office (very reputable derm doctor), the actual procedure is being done by his aesthetics's staff and not by him. She told me the procedure could be performed with or without PRP. The cost difference being $500. My question is, is PRP really worth it????
