What would help my acne scars? (photos)

19F The scars are at least 4 years old. I've had one round of Accutane which tamed my acne considerably. After that I've have 3 sessions of fractional CO2 all with a gap of a month and one of nano fractional CO2. (4 sessions total). But I've not seen much improvement. Moreover after being to 10+ doctors everyone gives varying opinions. Some say they're very deep some say they're okay. Some say subcision won't help and some say it'll help a lot. I am very confused, any help is greatly appreciated
