Has anyone tried this product? It's basically high amounts of Vitamin B5 in pill form & it's supposed to not only help with acne (which I only suffer with blackheads from, due to my skin producing way too much oil) but with reducing oily skin greatly.

I haven't heard of this, but it sounds interesting. I have oily skin and blackheads too and no acne. Keep us posted if you try it.

I might just buy vitamin B5 & take it once a day. I tried it once before, but I think I took it twice a day as the bottle (I thought) said. I do remember breaking out a little, which some people who take Vilantae claim occurred to them, but then they said to stick with it because in a couple of weeks that all goes away, as your body adjusts. Since right now my ONLY problem is oily skin, I'm afraid to try it and cause breakouts. For now, I'm using a product that is an intensive blackhead treatment, which I began on 9/27, so I want to give that 1 month and/or finish the serum and see what happens....
