Dior "airbrush-like" foundation since I had never experimented with a spray on foundation before. There was about a two second adjustment period after my first spray and the rest is history. This is probably the only foundation I will ever use again. It's that amazing. What's so amazing about it? You shake it (it sounds a little like a spray paint can), hold the can approximately six inches away from the face and spread an even layer. I like to do the forehead first and then move in a "Z" direction ending at the chin. Then I may do a little extra spritz on the cheeks (I try to contour even though I'm not great at it). Then I just rub it in a tiny bit with either my fingers or a foundation brush and voila - finished! A flawless face in about 30 seconds. I've found that this stays put all day. I usually put a little bronzer and blush on following but that's really all I need in terms of face makeup.
Two things to note when using this product:
1) I make sure to wear a headband (or at least pull my hair back) when spraying as it tends to get on my hairline
2) Since the foundation inevitably gets on my eyelashes, I always apply mascara following.
Although the price is a little steep at $62, you're really paying for perfect skin. Available at Dior.com and Sephora. I can't say this about most products but this one really has changed my life (and my morning routine)!
