Talk to Dermatologist on Acne Scars

“I have been suffering from severe acne for the past two years. I have already used several prescribed medicines like Vemos anti-acne cream, Sterol Soritine, Cerbic, H-A-T-Z lotion, and sunblock, but unfortunately, I did not see any improvement. Instead, some side effects appeared, such as dryness and cracking of my lips. My acne is still red, painful, and spread all over my face. Kindly suggest me the right treatment for my skin. Should I start oral medication like isotretinoin? Please guide me further.
