Well, you will not like this answer, but in my experience only accutane has been effective in reducing my sebum production. At the moment there are a couple drugs out there that are being developed to address oily skin, but they are in clinical trials and will not be available to the general public for some time. The drugs in question are DRM01 and SB204. The latter is closer to release than the former. So far both drugs have had little to no negative side effects so they look promising.

I made a log of my experience using accutane in the forums. Tl;dr is that i had very mild acne and used accutane 40mg/day over the course of a year. The only side effects was dry skin/lips, reduced sebum, and slight joint pain. Though I understand you not wanting to risk using it. I am unique in that I experienced virtually none of the major side effects.

One benefit of accutane is that although my oily skin returned within a couple weeks, I do not get any zits anymore (as of 3 months post-accutane). Any that I do get shrivel up quickly overnight with a dab of BP.

 

Unfortunately for us oily skin people, i think only oil-absorbing sheets are our temporary band-aid for now.
