I test drove two: Blue Bayou, which is not quite an electric blue, but much brighter and deeper than a sky blue–but there’s no teal or green in it for me; and Nuits Blanches, which is a very deep dark black. Oddly enough, I’ve found a lot of black felt-tip liners do show up a bit brown when swatched on the skin, but on the eyes, looks black as it’s supposed to; this also happened here (for reference). I wonder if, perhaps, it’s how close/magnified the photo is vs. viewing it in person at a real-life size. Anyway, just something worth noting.
The formula is definitely long-wearing and it dries quickly but not too quickly, so you do have some time to work. The formula itself is fairly water-resistant as well; I’m not sure I’d say entirely waterproof, but it doesn’t budge or smudge or flake throughout the day and takes a bit of elbow grease to remove. To be honest, one of my biggest frustrations with this product had to do with Blue Bayou staining my eyelid for three days. I don’t love products that stain overall, because I do find it annoying the next day, but having this slightly faded, residual blue liner on the outer edges of my eyes for three days was ridiculous. I know in the past, readers have recommended Make Up For Ever’s makeup remover for staining products, but between my cleansers, olive oil, and Lancome’s Bi-Facil, the staining wasn’t budging. I found the black didn’t stain nearly as much and seemed to fade away by the next day.
I will say that this the felt-tip applicator is very long and skinny, and those with smaller eyes may find this a little unwieldy. On my eyes, I felt like I had enough control to create thin, precise lines. I did find creating thicker lines to create a little more skill, just because the applicator is quite thin and more suited towards thin lines rather than thicker lines. I think with enough practice you’d find that you could get thin or thick lines without much fuss or frustration, though! The applicator distributes a good amount of product without it being too much or too little–there’s no drag nor is there excess that you have to worry about.
Bottom Line: I like and would recommend Nuit Blanches, because it works and functions quite well. I do take an issue with something that stains so intensely as Blue Bayou did, which makes me hesitant to recommend it. I didn’t take any points off for staining, but it’s something I think is worth noting as a potential problem for some (as it is for me). I used Blue Bayou last week in a look, which you can view here, to see how it looks in action.
