Talk to Dermatologist on Active Acne

Hello, i have been facing Cystic acne for a long period. Sometimes, it heals and completely gone. But now from the last four months i have an active painful acne. My Skin is oily and i'm on medication. Its 3rd month month I'm taking Azithromycin 250 mg, using Acnes Face Wash, Niaronic Serum, Clindamycin Gel for day time, Isotretinoin gel for NIght and after 1 month it replaced with Adapco and also Solar Max sunblock. After using all these products/treatment i did not see any good results and there are so many scars on my face. Suggest me please what should i do.
