Revlon Illuminance Creme Shadow comes in quads of four creme shadows. I tried the quad Not Just Nudes, which turned out to be a fairly nice set of nude creme shades.
The shadow itself is quite sheer, and only fairly buildable. If I had a complaint, I guess that would be it--I would rather see a bit more color payoff. But the sheerness still worked for me and the shadows blended very well because of it.
I did not experience issues with creasing, although I have seen other state that they had issues with that when using the Illuminance shadows. It appears that creasing is more problematic in those with oily skin, and I don't have particularly oily lids, so that may be why I had no issues with it.
The shadow lasted most of the day for me. It did not stick around as long as my favorite, MAC paint pots (read review), but it did a decent job. Mostly I just love the shades, which are swatched below:
