you could consider treating the existing acne lesions with topical and oral antibiotics as it currently doesn't look too bad. The alternative which I would consider is a prolonged period of LOW dose isotretinoin (minimising side effects while maintaining efficacy).
Your acne scars will definitely need subcision + fillers, fractional lasers and TCA cross to target the depressions/atrophic scarring, and icepick scars.
Consult your derm or aesthetic doctor and discuss your expectations AND constraints (social needs and budgetary)
