Do you really need the Beauty Flash Balm as a base/primer after your regular moisturiser? I would only ever use it if my skin felt really parched as it creates a very "dewy" look on my skin. It's quite a rich moisturiser when you combine it with a regular moisturiser. Just a thought I find the Smashbox photo-finish the best I must admit for creating a long lasting base.
For amazing coverage the Estee Lauder Double Wear is probably the best and lasts the longest for me. I tried the Dior spray foundation (my sister bought it), to be honest I thought it settled in my pores if you get me? Looked fab on her dry skin though. But maybe I didn't apply it right.
I'm completely won over by a Chanel foundation at the moment though - it's called "Mat Lumiere" - it gives such a lovely finish, not a chalky powdery finish like a lot of matte foundations. I combine this with the Chanel Primer which I find lovely but don't think it's as good as the Photofinish. I should add that I have very combination skin, so it can get quite dry on the cheeks but horribly oily on the T-Zone and I just find that this foundation really suits me. Too pricey for daytime wear though - so I wear a mineral powder foundation by Fuschia (www.fushcia.ie) every day which I find pretty good, but it does get shiny by lunchtime! So I'm usually reaching for the rice powder to keep things looking ok, seems to work, HTH
I use Beauty Flash Balm most days but only the teeny tiniest little biteen of it because as you said it can leave you with a very "dewy" feel to the skin but of all the primer-type things I've tried, it seems the best. If I don't use something, my foundation just seems to melt away into my skin and after an hour or so you wouldn't think I'm even wearing any but that my face just looks grubby. The Clarins Smooth Perfecting Touch is really good too, but that little bit oilier than the flash balm so I tend not to bother with it.
I made a resolution to carry my blotting papers EVERYWHERE with me instead of just leaving them in the car and blotting while I have a spare minute in traffic or whatever and I have to say it has helped over the last week.
I've tried mineral foundations and just can't go for them. Maybe I'm not applying them properly (though I've followed the instructions and demos), they just seem to look like muck on my face.
Have also tried MAC, wasn't gone on it either, was really disappointed as it has such a brilliant reputation.
I've decided I'll stick with Clarins for another wee while anyway but I'm giving serious thought to that Chanel one, might go for an trial soon, thanks mavisoc
