This is a bit out there, but it actually helped when i had acne. I developed adult onset acne when i was 31. Out of the blue i started breaking out and no matter what i tried it didnt help. Went to the dermatologist and she gave me Retin-A. That just tore my skin apart so i stopped using it. My sister in law gave me a bottle of Keri antibacterial hand lotion one day for my hands, and i used it on my face and sure enough it actually helped a LOT. I guess it sort of makes sense since acne is usually from bacteria. (I dont think they make the Keri antibacterial lotion anymore). Any way shortly after that i was diagnosed with cepacia and my Dr. put me on Minocycline on a rotating basis every 3 - 4 weeks. Every time i was on it my skin cleared up. Eventually it cleared up completely and the acne never came back. I hope you find a solution, and eventually you will. I know how frustrating it is.
