Illamasqua Nomad. Unfortunately, the color isn't accurate. It looks turquoise/aqua in the pic, but it's really much more green. Like Granny Smith apple green.
I love this color, but the application for me was a problem. Bubbles started to appear after the first coat, and then it seemed gloopy after applying the second. I'm not sure if there may be an issue with the Butter London base coat. This is my second time using it and I think I'm not liking it. It's also supposed to serve as a ridge filler, but I think it makes my ridges seem more apparent. A problem I never had before. On the flip side, I do love the Butter London top coat. It actually saved my Nomad mani. It hid the bubbles and made everything appear more smooth.
But I love Nomad's color so much that I'm willing to deal with the hassle. Nomad is like a diva supermodel. It's difficult to work with, but you get beautiful results. I'm going to keep in mind that my issues could've been because of incompatibility with Butter London's base coat. I don't recall anyone else mentioning these issues with Illamasqua.
