I nearly walked past this beauty before I realised what it actually was! Formula X is the Sephora brand nail polish, obviously only available at Sephora stores. I could have waited until I went to Florida this August, but it was only £1 which made it cheaper than if bought out of Sephora.
This is part of Spehora's shifters nail lacquers, which are duochromes. I purchased the shade 'Iconic' which is a cross between an emerald green (the picture above) and a gold (the picture below). It's a really interesting reflex between the two. I have no other colour even similar to this; it's a perfect addition to my collection.
The pigmentation of this nail lacquer is amazing. After one coat the nail was completely opaque, but I put two coats on as it is my norm. I added a layer of topcoat on top for extra shininess. This manicure lasted me nearly a whole week; very impressive as I am quite heavy handed.
What do you guys think - yay or not your type?
