There's actually not much to say about this foundation because..... IT'S CRAP!!!!!
I got a sample size of this because I wasn't sure if it would be too drying on my combination skin (really dry and extremely oily at the same time, bah) and I wasn't sure about the coverage. I like light coverage foundations, but I've heard that this provides a really sheer coverage, almost like it's not visible on the skin at all and gives you nothing. Well, that's true. It provides ZERO coverage. A little bit of colour, that's it. I got it in the shade Gobi, which is a OK match for me. A little too yellow, but that's alright. The colour selection is big, which might be the only positive thing about this foundation.... It covers less than a translucent powder for christ's sake. And that's bad.
When it comes to application, I do not recommend applying it with a sponge. The first time I tried it out I used my BeautyBlender, and the sponge sucked up aaaall the product, leaving nothing on the skin. I don't know what it is about the foundation, because I apply every single foundation I use with my BeautyBlender and it always works, even with waterbased foundations like Chanel Vitalumiere Aqua (only tested it a couple of times, I don't got it in the fullsize). I've tried with different foundation brushes, but with no luck. No coverage, no even application. The formula is really dry and weird. When applied it doesn't feel like a regular liquid foundation, it just feels dried out and disgusting, not soft at all.
I don't know anything about the staying power, because I have never worn it for more than 1 hour. My skin looked terrible after applying it, even though it provided zero coverage and just a hint of colour, it clinged to my dry patches and made my skin even more oily than before. Instead of making my skin look healthy, matte and just ok, it made my face look almost destroyed. I don't know how it's possible... Worst foundation ever, will NEVER EVER buy it in fullsize!
