Sorry to see that you are still suffering from acne and acne scarring.
I believe you need to restart the isotretinoin and we need to review the dosage and duration. From your photos, you continue to have a lot of underlying comedones (blackheads) and these need to be addressed. With the right combination of treatment, I believe you can control your acne successfully.
Once the active acne is controlled, you can then focus on the acne scarring which can be improved with a combination of subcision, punch excision and fractional CO2 laser to treat the different types of scars.
Do let us know if we can be of help. Hope you get better soon!
Warmest regards
