I'm fair skinned and have incredibly dark circles, no matter how much rest I seem to get. With all the great reviews, I really wanted to give this a try, and I was thoroughly disappointed.
First off, I thought the top would be more like a beautyblender sponge type applicator. It's more of a weird, prickly, not quite fuzzy and not quite spongy thing that gets weirdly damp. I haven't had any issues with it breaking yet like many people, but we'll see I guess (If I continue to use this.)
I fail to see the purpose of that applicator because I still need to use a blender of another sort to make it work, so it would actually make things easier if I could use a more precise concealer applicator and then blend it out.
The other issue I have, is that even with one layer of product, this creased all to heck, even when I tried setting it. And that leads to the next problem-- one layer is not nearly enough. It was incredibly sheer coverage. I tried layering it, and couldn't achieve any semblance of actually covering my dark circles.
Finally, the shade range is problematic for me. As stated before, I have fair skin. Which means that the brightening shade AND the fair shade are both about the same color as my skin tone, and would only serve to make my undereye circles less dark, not actually brighten anything.
I was really hoping for a great drugstore concealer, but it's back to NARS for my undereye.
