This product is both a primer and an eyeshadow. I purchased this in Sultry Satin which is a soft candlelit sandy gold. It looks lighter than the photos. I love that it has a doe foot applicator for easy application. As for making my shadows last I think the hold was comparable to UDP and Too Faced Primers but this one is a total steal at 2.00 a piece on their website. This shade has a very eye brightening effect and is good for softening fine lines around the eyes. I intend to pick up the Coco Loco next which looks to be a soft taupe-cocoa.
