I know I'm soooo late to the party here but I am absolutely OBSESSED with Revlon Colorstay! I can't tell you how pleased I am to have discovered this amazing foundation that 100% knocks my NARS Sheer Glow out of the water and it's a fraction of the cost. The coverage is absolutely unparalleled for me, it's buildable to double as concealer, it really DOES last all day AND it comes in combination/oily which prevents the breakouts that usually come with a heavy, long lasting coverage. It's just unbeatable... in fact I wont be looking any further. I no longer need to try the latest ANYTHING! I've found my ultimate, holy grail foundation end of story.
I should probably also mention for all you oily prone girls like me that although it doesn't keep me matte ALL day it leaves me with a glow at worst. Who else LOVES this like I do?
