Sorry the late update but I got sidetracked by a bunch of stuff. I stopped taking resveratrol a couple of weeks ago. Unfortunately whatever miraculous oil-reducing effect I saw in the beginning has disappeared. By the end of the experiment, the resveratrol may have been reducing my oil production slightly, but not enough that I could confidently recommend it to anyone else. I don't know if my initial results were due to the resveratrol or if my body was simply being nice to me for a few days, but something was definitely reducing my oil production for a little while there.
As for the 5 Alpha Avocuta by Noviderm that I was applying to the right side of my nose, it didn't help at all. The company claims that oil-reducing effects were confirmed after one week of use in their trial. I used the cream for 8 weeks and saw no reduction in oil.
