Great for oily eyelids
Usually, when I use a powder eyeshadow, I have to do a lot of prep (primer—>setting powder–>eyeshadow–>setting spray). Even with all of that, is still sometimes settles in my creases at the end of the day.
When I tried the eye paint for the first time, I did not do any prep whatsoever, went to a convention, and walked around for seven hours. At the end of the day, it looked like I just put it on! The only issue I've had is it's a bit hard to make it opaque in the inner corner when I use a brush.
