Formula X is meant to be very gel like and last on the nails for a more extended period of time than the regular polish. I do think this looks very gel like in the fact that it looks very shiny and it curves your nails much like the gel polish. Perfection (just like metro chic) is a gorgeous purple taupe mushroom shade, in the dirty family that looks amazing with short nails and it's perfect for fall and winter. Overall, I'm very happy that Sephora is offering a pretty much exact dupe and highly recommend this shade.
Hope you all have had a lovely day.
Loads of love
