This is the description on the Debenhams website: "Urban Decay launches Moondust Eyeshadow, a dazzling innovation in eyeshadow with a super-refined and incredibly sophisticated feel. Forget EVERYTHING you know about glitter eyeshadow. Moondust is like NO OTHER shadow. There's not a speck of chunky "teen glitter" be found in these babies. Microfine bits of iridescent sparkle collide with intense, dreamy hues and lush 3-D metallics - for an effect that's out of this world. And while some traditional sparkly shadows tend to look cheap, Moondust has a really luxe, upscale vibe and a gorgeous, diamond-like effect." These are definitely very sparkly. They are also pretty pigmented, so you actually get a lot of colour as well as a lot of sparkle. Initially they reminded me of the Stardust eyeshadows, but these are a lot more intense, both in colour and also in sparkle.
These eyeshadows are not only very sparkly, but they're also duochrome, some more than others, in particular Stargazer which has a gorgeous green duochrome to it. Zodiac is my favourite of the 4, it is amazingly intense and is full of green, blue and gold sparkles. I found Glitter Rock and Intergalactic quite similar on the eyes, although they swatched more differently, but Stargazer and Zodiac gave a great contrasting look.
Urban Decay recommends you apply these using your fingers, I swatched them with my fingers, but I prefer applying eyeshadows on my eyes with brushes for precision. These eyeshadows can be used dry or wet for more intensity. I haven't tried them wet yet. As for glitter fallout, there was surprisingly little, I mostly only had some during application and blending. Once I cleaned it up, I didn't notice much glitter fallout. I would say that if you didn't like glitter, you'd probably wouldn't want to go anywhere near these anyway since they are so sparkly. But they definitely didn't spread all over my face. I didn't notice any creasing either (I used them over Too Faced Shadows Insurance) and they looked vibrant all through the day.
These eyeshadows come in the usual round Urban Decay eyeshadow compacts and by the looks of them can probably be depotted and put into their new palettes (which I don't like one bit, but anyway). You get 1.5 g of product for £14. Urban Decay is stocked in Debenhams and House of Fraser, and they are currently on sale at BeautyBay (£12.46 each), although Zodiac isn't in stock.
