As I posted, I recently found a display with a new Sinful Colors matte top coat (which sells for $1.99, the same price as the other Sinful Colors polishes). I’ve tested it out, and I have a review and some comparison swatches for you! In the photo below, I have two coats of Nails, Inc. Black Taxi (a shiny black creme) on all four fingers, and then my index and ring finger each have one coat of the matte top coat. There’s not really much to say about it; it certainly works!
I only own one other matte top coat – NYC’s Matte Me Crazy top coat, which is also $1.99. For the following photo, I left the two Sinful Colors nails alone, and painted the two glossy nails with one coat of the NYC topcoat.
Please let me know if you can detect a difference – because I definitely couldn’t; the finish was identical. The consistency of both polishes was identical as well – just slightly thicker than I’d prefer, but easy enough to work with.
I’ve heard that the NYC Matte Me Crazy is less matte / more satin as compared to some other topcoats (like the Essie Matte About You), but I couldn’t find a clear comparison of the two. If you own multiple matte topcoats, please let me know in the comments whether you can tell them apart!
