Posted by Rachel on 3rd Nov 2018I put this on for the first time as I do with any usual nail polish -- under my lighted, magnifying hobby lamp. But this one is SO BRIGHT that I had to turn off my lamp! This is definitely one of the top three best polishes I have ever used and it has made me obsessed with the Cirque Colors brand. It was almost opaque in one coat and the formula is perfect. And, if you want a lot of compliments and attention from others, get Halcyon! It's a stunner!
