I this better than Urban Decay's eyeshadow primer. I have oily eyelids and they are slightly hooded, so by the afternoon (or even late morning), literally everything creases. This is working better for me than Urban Decay's eyelid primer. That is really, really saying something.
When I want to bump up my longevity and flawless look I will always go to this! What a fantastic primer NARS makes. I've used others, they all work well enough. I purchase NARS because it really goes on well and lasts. It makes my eyeliner easy to glide on and smudge. I then top that with the powder eyeshadow and it sets it all beautifully!
