Urban Decay Spacetime Liquid Moondust Eyeshadow ($22.00 for 0.17 fl. oz.) is a dirty, medium-dark khaki bronze with warm undertones and pink and green sparkle over a more metallic finish. The texture was smooth and more blendable than the majority of the shades in the formula, and this was one of the few that could actually be worn as an opaque layer of product. It was buildable from medium coverage. This shade wore well for nine hours with no fall out whether applied as a single layer or applied as two layers. The application was still fussy, and it was easy to blend it too much and get a patchy mess, but it was one of the few that I could actually apply decently.

Urban Decay Zodiac Liquid Moondust Eyeshadow ($22.00 for 0.17 fl. oz.) is a blackened green with warm undertones and copper, emerald green, and gold sparkle. It had semi-sheer to mostly opaque, buildable coverage. The consistency wasn’t as watery as other shades, though it had a tendency to sheer out rather than building up–you have to be completely certain that each layer has dried down. It started to look rough and textured with anything more than two layers. I had no fallout when I applied this as a sinigle layer, and I had no fallout or flaking when I applied two layers.

Urban Decay Vega Liquid Moondust Eyeshadow ($22.00 for 0.17 fl. oz.) is a bright, medium-dark blue with cool undertones and silver and blue sparkle. It had semi-sheer coverage that was buildable to semi-opaque pigmentation with two layers. The texture was unforgiving when used as two layers, as the color would clump up and look chunky. It was hard to blend out, so it always had a look of patchy, uneven coverage, so it would work better over a darker base color, which would help fill in the gaps. It wore well for nine hours with no fallout when I used one layer, and when I used two layers, I had some minor flakes over an eight hour period.

Urban Decay Magnetic Liquid Moondust Eyeshadow ($22.00 for 0.17 fl. oz.) is a medium-dark purple with warmer undertones and pink and copper sparkle. It had semi-sheer color payoff that was somewhat buildable to semi-opaque pigmentation. The texture of this shade seemed a bit thicker, a little more like a liquid-cream, and it remained blendable for longer (but fast enough that it didn’t crease). It does thicken and add texture to the lid if applied in two layers, but it was not as bad as some shades in the range. When I wore it as a single layer, it lasted for nine hours with no fall out, and when I wore it as two layers, it lasted well for nine hours with minor fall out but no flaking. MAC Panthertized (P, $22.00) is darker (90% similar). NARS Canberra (LE, $25.00) is less shimmery (90% similar). Tom Ford Beauty TFX7 (LE, $36.00) is lighter (90% similar).

Formula Overview

Urban Decay Liquid Moondust Eyeshadow ($22.00 for 0.17 fl. oz.) is supposed to be a “liquid version” of the powder-based Moondust Eyeshadow formula. The difference (besides consistency!) is that these are designed to have a buildable formula that can be used on the lash line, over other eyeshadows on the lid, or on its own, and once it dries down, it “won’t budge or crease.” I felt like it was an overly fussy product, and I think it takes extra work and very specific preference to make them “worth it.” I’d much rather use the regular Moondust eyeshadow, which is even $1.00 cheaper (it is hard to compare liquid vs. powder weights, so there could be more uses in one than the other).

For the most part, they’re sheer to semi-sheer and somewhat buildable, but the texture doesn’t support layering. I don’t think they are that usable on their own, because they dry down quickly and are hard to blend out–they look patchy and uneven–and trying to build-up color by putting additional product on the same area always resulted in a thick, chunky, and uneven disaster on the eye. I tried layering them over eyeshadow as well, and from afar, it can be pretty, but they look horrific close-up as they are the same on top of something else: uneven with poorly distributed sparkle. The tiniest dab on the inner lid that you don’t touch or blend opened up the eye, but I tried brushes (including the brand’s Moondust brush), fingertips, silicone applicators, and the included brush (on the applicator) to no avail. I only had moderate success using the included applicator and layering it over eyeliner.

The formula itself was inconsistent every time I used a shade, because the product doesn’t seem to be well mixed, which results in sheerer and thinner, more pigmented and chunkier consistencies. They don’t really mix up, but you can try to twist and maneuver the wand into the product to try and mix it that way. The highlight of the formula is that there was virtually no fall out across all the shades except for when I tried to layer or build-up color, then sometimes I’d get a big chunk that would flake off entirely, but when worn on top of liner or as a single layer of product (on top of eyeshadow or alone), I had no fall out.

I also found the included applicator is particularly disappointing; it does nothing to improve application as it is a coarser brush that’s rather stiff, which means that it is hard to get any evenness out of it. It tends to glob product on rather than give you a sense of precision. The coarser bristles hold product in them unevenly as well. It is the type of brush that when pull it across the skin in one fluid motion, the product pulls to the side and leaves almost nothing in the middle.
