Tired of my acne not getting better after using various products, what do i do?

Hello, so i’ve been fighting acne for about 5 years now, since then i had visited about 4 different dermathologists and used probably about 15-20 different products. None of them have helped and some made my acne even worse. I’m past the worst state it was in and now it’s just about getting like 4 or 5 pimples a week with occasional worsening for like 2 days or something. Since i have ulcerative colitis i can’t use strong medicine for it and almost all the meds that are in the way of pills. I need help cause nothing is really helping and i hate how my face is literally all red from the scars. here’s photos of my face for reference: Imgur: The magic of the Internet
