Mattifying primer for really oily skin?

[Fluffycloudland77]

What really works?. I'm shiny by noon

Yes to setting spray. I love the Urban Decay one but I've used the MUA one too. It's also good for getting rid of a powdery finish.
I also find a layer of moisturiser, then powder, then foundation and powder again works. Sounds like it'll be a cakey mess but it really isn't.

Ooh StayGold, must try that layering tip, thanks

I have tried Smashbox, Bare Minerals, Mac, Lanacane and Clinique. This week my Mac primer ran out and as I don't get paid until Friday I bought Rimmel Stay Matte. Two days of use and I rate it the best I've used. It's even cheaper than Lanacane

YSL Matt Touch is very good but can makes a lot of people's skin break out

Seconding the milk of magnesia recommendation - it works miracles.
