China Glaze Glistening Snow is micro silver holographic glitter in a clear base. I thought that it would be more of a glitter topper but this baby can get opaque quick. I used 3 coats for the swatches below but only for photo purposes. I could have easily left it at two. It does dry somewhat gritty so you need a couple coats of top coat. I'm wearing two coats of Out The Door.
They are definitely not dupes though! Fairy Dust is not opaque at all. It's a glitter topper. If you used just one coat on top of your mani, it would give a nice clear holo sparkle. I used three coats keep it the same as Glistening Snow. I'm to say if you are a holo girl, you need both of these polishes. They serve different purposes!
There you have it! What do you think of Glistening Snow? I love it!
