How can I treat the pitted acne scars on my forehead and cheeks? (Photo)

29 year old Male. Suffering with acne since 17, started accutane 6 months back. Currently, skin has been clear since 3 months, on a low dose of accutane now for maintenance ie 5 mg. Have lots of scars on cheeks and forehead, sending pictures of my face after 6 rounds of RF Microneedling + PRP as well as 2 subcision. Scar on my forehead is due to cortisone injection that was injected on my acne. I have also done various microneedling sessions but the scars wont go away. What are my options?
