Treatment for mild to moderate acne?

Patient: Benzaclin cleared my acne for about 2 and half years and then completely stopped working. I’ve also tried Proactiv which made my acne much worse along with Panoxyl 10 which also damaged my skin really badly. I’ve tried Retin-A tretinoin .05%, Doxycycline, and Minocycline. All to no avail. I really can’t find anything that works.

Symptoms: Scarring, whiteheads, inflamed bumps, redness

Doctor:
