In my stash, I had four matte white eyeliners and three shimmery/metallic white eyeliners, and I’ve compared them in this post. The finding? The matte white eyeliners are completely dupes of each other across all four shades, while the metallic white eyeliners are nearly dupes of each other, with one being minutely less bright. I like using white eyeliner to lighten other colors or to act as a base color when using eyeshadow on the lower lash line.
I actually reviewed Glamorous Thief and Amethyst Android when these originally launched here, and I liked them then–and I really love the Eye Dream Hyperliners generally, after trying several shades for the past few weeks. I’ve been digging Locket Book and Sparkling Ammunition for a defined eye that’s not as stark as black. These are so, so smooth. They have the same softness and smooth application as Urban Decay’s 24/7 Liners, actually, which wasn’t how I felt originally. They deliver a fair amount of pigmentation in a single pass, though I’d probably use the same back-and-forth method I typically use with eyeliners for a really rich, opaque line of color. They hold up well without budging, fading, or smudging. I’ve worn them during a shower (the easiest and quickest way to test out “waterproof” claims–plus, humidity!) and had no issues there.
