NARS Back Room Nail Lacquer ($18.00 for 0.50 fl. oz.) is described as “black.” It’s a rich, deep dark black with a glossy finish. I know it’s going to sound bizarre, but I don’t have a lot of black cream polishes. MAC Nocturnelle is one of the few I have (and for some reason, I have a few of them). It’s not quite as dark and doesn’t dry down to the same naturally glossy finish. MAC Beyond Jealous is a tiny bit teal but mostly black. What’s your favorite black cream?
