I've been taking vitamin A pretty consistently for several months now and it has made no dent in my oil production. I think it may be helping to keep my skin clear of acne, though.
So I'm going to stop taking it. Not only are the results negligible, but I've also been getting some really irritating side effects. The worst is terrible headaches every morning, which is a common side effect of vitamin A. Another side effect I've been experiencing, which I've never seen linked to vitamin A, is poor sleep. I wake up a couple hours earlier than usual and can't get back to sleep. Also I randomly get very sharp pains in my sides. I've experienced this since I was a kid, but the frequency of the pains has increased since being on vitamin A.
So my search for an oily skin cure continues...
