That's some promising news. I was curious - which brand of resveratrol are you using?
Okay, I try not to rave about new products prematurely, but it's been a week since I started taking resveratrol and I'm definitely seeing reduced oil production on my face. The effect is pronounced enough that I've already ordered another batch of resveratrol, and it's not cheap ($25 for 12 days worth of pills in my case).
I'm still trying to remain skeptical and I'm totally open to the possibility that something other than the resveratrol is causing this change, but something is reducing my oil. Right before taking resveratrol, I took saw palmetto and nettle root extract for one week. What I'm seeing now could possibly be a late effect of those supplements, though I'm equally skeptical of that.
