Manuka Oil (I use East Cape which can be bought through Koru Naturals) is fairly cheap and highly effective for me. Works better than benzoyl peroxide, is easier on the skin than Retina A and other topicals you get from the derm. The smell is a little weird and strong, but you get used to it especially since only a small amount of oil is needed. Research indicates that Manuka Oil has potent antibacterial, antifungal, anti-allergenic and anti inflammatory properties. What's key here is that Manuka Oil fights the bacteria that inhabit the sebum in the sebacious glands and cause acne while also reducing the inflammation of existing acne. I just recently started using it thanks to a friend's recommendation and I now swear by it. In one week I went from feeling like the elephant woman with 75% of my face broken out (thank you bare minerals oil control primer for that lovely issue) to feeling presentable in public again. This stuff is fairly cheap, natural, effective, and far less harsh (even on my sensitive skin) than any topical acne medication a dermatologist has ever recommended for me. Give it a try and be patient. You will see results.
