Works great!

Works great! I got this as a sample from Sephora and gave it a shot. Normally I use mineral makeup, as that's the least reactive with my skin and lasts longer than two seconds, but I generally dislike wearing foundation because it looks like I applied it with a trowel. (I have THAT kind of skin.) I prefer a more natural look. I was somewhat wary of the "one shade fits most" claim because I'm invariably never one of the "most" meant. Still, free sample, worth a try.
My first attempt ended up looking decent, better than the mineral makeup, but showing clumps of pigment and highlighting the dryness of my skin despite moisturizer. For my second attempt I applied a makeup primer (really my usual night moisturizer, Decleor Rose d'Orient Night Balm, but it works marvelously as a primer as well) and tried again.
Soft-focus perfect 50's pinup skin was the result. You know the pictures where you KNOW they're wearing makeup because no one has skin that perfect? Even under harsh lighting. The coverage was sheer enough that I still looked human, no trowel appeared to have been involved, and it LASTED for hours and hours. Makeup normally vanishes within three hours on me. The shade also blends decently with my skin tone.
I do recommend this if you prefer sheer coverage (it's not a spackle-on product), and it'll be best applied over some sort of primer. I think I have a new foundation that WORKS finally.
