According to the website, "Sheer wash of lightweight, creamy colour slips on. Layerable and long-wearing. Versatile, too. Glide one on for a swift wash of colour. Contour with another to add depth, and yet another to highlight. There's no need to stop at just one." I usually wear it over Nars primer to get through my 12 hour days at work, but it makes it has decent staying power on it's own. It does not need to be set with powder at all either, which is even easier. The twist up pencil is always great, and the large size makes it easy to do a quick wash of color, but difficult to do anything more precise.
These swatches show heavy and blended application.
This is a photo from around 6:30 in the evening after wearing it for about 12 hours at work. Some creasing, but overall not too bad!
