Urban Decay Chem Trail Moondust Eyeshadow ($21.00 for 0.05 oz.) is a light-medium, champagne gold with warm undertones and a lightly sparkly, metallic finish. It had finer sparkle and less of it than a lot of the Moondust eyeshadows, so it was easy to work with and had no visible fall out over time (tested for eight hours). The texture was smoother and easier to work with as well. LORAC Cashmere (LE, $19.00) is less shimmery, lighter (95% similar). MAC Cool Companions #1 (LE, ) is less pigmented (95% similar).

Urban Decay Horizon Moondust Eyeshadow ($21.00 for 0.05 oz.) is a soft, medium-dark brown with warm, rosy undertones and chunky gold glitter and fine pink sparkle. It was almost a mauve-brown color, as you can see the strength of the pink tones and sparkle on top of the brown when applied damp. The texture was very chunky, so it was harder to work with dry, and even applied damp, it was best patted onto the lid and layered. I would advise using a glitter adhesive with this shade to get the most bang out of the shade. I had some fall out when I used it dry, and it only lasted for six hours before creasing. When I tried it damp, it was significantly more opaque and had noticeable fallout but it was less than dry application.

Urban Decay Dark Cloud Moondust Eyeshadow ($21.00 for 0.05 oz.) is a medium-dark gray with lighter silver and pale pink sparkle. It had semi-sheer coverage applied dry and mostly opaque coverage applied damp. The texture was noticeably glittery but went on fairly smoothly, and the flecks of sparkle were larger and flat enough that they seemed to adhere to bare skin (even when blended, they tended to disperse across the skin without dropping). I had minor fall out when I used it dry and almost no fall out when I used it damp. MAC Say It Isn't So (P, $18.00)(100% similar).

Urban Decay Gamma Ray Moondust Eyeshadow ($21.00 for 0.05 oz.) is a medium-dark navy blue with cool undertones and a metallic sheen that had a light dusting of lighter bluish-teal sparkle. This shade was smoother and not quite as glittery as some shades, but it had a noticeable amount of sparkle nonetheless. Applied dry, it had semi-opaque coverage that lasted for eight hours with a minuscule amount of fallout, while damp application yielded opaque coverage and almost no fallout.

FORMULA OVERVIEW | Urban Decay Moondust Eyeshadow ($21.00 for 0.05 oz.) is specifically designed to be over-the-top sparkly with “minimal fallout” and sheerer coverage dry, more “intense color payout” when applied wet. I like using flat, synthetic brushes (or fingertips, as the brand suggests) that have been slightly dampened by a spritz of just water. If you want extra-long hold, I would still recommend a glitter adhesive, but I get pretty good wear with little fall out without any primers or adhesive, as the formula has a smoother, almost wet consistency. They work better combined with other eyeshadows than using several at once, and they tend to look more impressive in person than in still photos. Some shades are better than others; the ones with stronger base colors even when applied dry tend to have the least fall out over time.
