Decently long-lasting & water-resistant
I absolutely LOVE the brush tip. It’s quite long and sharp, so it’s really easy to work with. The formula itself is good enough, and probably the best waterproof eyeliner I’ve gotten that’s reasonably-priced. It glides on well, is quite pigmented, and works great overall. I wouldn’t say it lasts all that long, but definitely far more than any typical liquid eyeliner will (especially if you layer it); I wear a LOT of eyeliner though as a goth woman lol. I’d say it reasonably lasts 6-8 hours, sometimes an entire day; it also helps if you regularly deal with the oil that might build up on or around your eyes during the day (because oil will take it right off). However, after having used like 6-8 by now, it typically dries out after the first couple days of use, then makes a come back a few days later. I have no idea why, but just know, if it seems to dry up fast, it’s probably not actually “gone” or used up. I’m impatient though, so sometimes I will add a touch of water… which you probably aren’t supposed to do for a waterproof eyeliner, but oh well 🤷♀️ It completely revives it, so I don’t really care. I’d recommend layering the eyeliner 2-3 times (not much more, or else it will pill and might flake off a bit), because the formula is pretty thin. Also, I have decently sensitive skin, and this formula has caused me absolutely zero irritation or any other problems. Idk I think it’s definitely worth a try at least if you’re looking for a reasonably-priced water-resistant eyeliner.

Excelenteeee
Muy delgado, dura todo el día y no explota cuando te lo llevas en avión (como el de NYX)

No comparisson
This does what irritating and expensive lash serums won't do, for less. It's easy to use, lasts several months despite daily use, and despite being long lasting it doesn't stain my skin. (Great for sensitive eyes too)

No es lo que promete
El delineador venía muy debil, sin tinta. Lo pasé varias veces por la piel y no quedaba el color con la intensidad que promete
