I'm actually surprised at the extremely negative reviews this has. It's not a concealer, so of course it's not going to cover anything! What it's meant to do is be applied under your concealer, over your concealer, or mixed in with your concealer to add extra brightness. I really really love this product, a lot! After using it, I really don't think I could ever go without it again. The way I use it is I apply some to the back of my hand (roughly 2 full swipes) and then apply half the amount of concealer I would normally use, and then blend the two together, and oh my gosh the results are incredible. Not only does it slightly lighten my concealer and makes it more brightening, it also sheers it out a little bit, and for some reason, whenever I mix this product with my concealer, my concealer NEVER creases and ALWAYS looks flawless. Before I started using this my concealer would always look really obvious, cakey and dry, no matter which one I used. This product is holy grail status to me, and I think if some of you try the mixing method I suggested, you will feel the same!
