Agree with most of the other reviews that this sadly is a fail. I decided to try this because this was one of the few eye primers I hadn't tried, and I need a primer if I want any kind of eye makeup to last more than 30 minutes. One past favorite of mine, Tarte 360, had been discontinued. Other primers that were relatively highly rated didn't work for me, so I thought I'd give this one a go despite less than stellar reviews.
The Smashbox Lid Primer does in fact weirdly make your eyelids look wrinkly, even if they aren't wrinkly to begin with. (The effect is minimized if you pat the product onto your lids with your finger instead of using the wand.) But that hardly matters, because it isn't an effective primer anyway. It makes an absolute mess of stick or cream shadows, causing them to immediately clump up. In an eye-to-eye test with Nars Pro Prime eye primer using powder eye shadow, the eyelid prepped with the Nars had much better staying power. The eye makeup that had been prepped with Smashbox faded, migrated, and creased after a few hours. Returned to Sephora.
