Acne caused by new products. Be?

Hi doctors, I'm a T1D and I'm also on antidepressants... I had some mild post-acne marks which were very mild, so I searched about it and after talking to Al, I started using 10% azelaic acid and 5% benzoyl peroxide. The azelaic acid was making my skin itchy, but I continued using it. I was also using it randomly rather than following a proper routine. The benzoyl peroxide caused me some peeling and tiny bits of skin coming off. I have stopped using both, my acne pains and now I have stopped but my acne seems to be getting worse.. I'm only using SPF 70+ sunscreen. Please advise me on what I should do and what this could possibly be? I just want to know what it is and if it needs immediate care, I'll consult a dermat. Thankyou for your valuable time doctors
