I was foreve on a mission to find the pefect foundation, and thought I had cracked it with a Neutrogena one which was fantastic. Only to discover 6 months later that they'd stopped making it. So the search continued... I have now found that a Bourgeois one is just as great, think it's something about 10-hours or something...? Its around �8.00 and comes in what looks like a tiny pump bottle. However I'm still on my first one after 4 months. I use it every day without fail, sometimes twice a day. Its really light, so doesnt go cakey, ut covers all flaws perfectly (I have faint acne scars which are no problem with this one).
Good luck in your hunt!
