Like many other reviewers, this works as a 2-for-1 for me. I use it every day - on "no make-up" days so that it helps even my skin tone and to brighten my eyes (my eyes have dark circles - all the way around) and as a base for days I wear eyeshadow. On the days I wear it alone, I might get a slight crease soon after I put it on, but once it's all dry, it doesn't crease again. I am blonde with fairer skin and wear Bare.
This is an amazing product! I love that I can wear it alone for a just a hint of coverage for light makeup days or use it as a primer base to hold my eyeshadow in place all day long. It really brightens and opens my eyes up, honestly it is like having 8 hours of insta sleep in a easy to carry tube. My secret make up weapon of choice.
I have tried a lot of eye primers, and this one is by far the BEST. You can wear it alone, and it evens out the skin tone of your eyelid. Or wear it under eyeshadow, and your eye makeup will look flawless all day - no creasing at all.
