This is two coats. Zoya Hazel is described as a full coverage, blue green foil metallic. To me it's more blue silver gold foil metallic. The formula is perfection! Goes on easily and it's completely opaque in two coats. I love foils and this one is amazing! Hazel reminds me a lot of Zoya Crystal which is also part of the permanent Zoya line. But Hazel is more silver and Crystal is more blue. Here is a picture of Zoya Crystal:
Here's a close up of Hazel, you can see the blue foil with some goldish green foil flakes.
Anyway, thanks so much for reading! I hope this review was helpful! I'm also on Instagram @Nailsneverfails
