Marc Jacobs Beauty See-quins Liquid Eyeshadow ($24.00 for 0.19 fl. oz.) is supposed to be long-wearing with “all-day, crease- and fallout-resistant sparkle” that you “swipe on and blend” for “instant, fuss-free dazzle.” They’re supposed to have “customiz[able]” coverage that can be sheered out or built up for “high-impact dazzle.” Some shades had more medium coverage while a few had semi-opaque to opaque coverage, and most of them were easy enough to sheer out for more of a wash of color.
The doe-foot applicator was comfortable to use but tended to over-apply the product, so I’d recommend using a separate tool to pick up product off the doe-foot applicator and then using that separate tool to apply the product to the eye area. The texture was more of a whipped mousse–airy but wet–that was quick to dry down to a long-wearing, crease- and transfer-resistant formula that didn’t suffer from fallout. I think if you were someone who accidentally rubbed your eye, it’s possible that a couple of sparkles or a small chunk of the product could flake off, but I didn’t experience flaking just wearing it over a 12-hour period.
As most of the shades had larger flecks of sparkle, they did not always build up in a flattering way; the finish can look somewhat chunky, almost raised or more textured on the lid, when built up (I would not go more than two layers), though in person I find that it’s harder to “see” that added texture.
