Duraline.

"Inglot Duraline, tried and true little Inglot Duraline in there to make it a little more liquidy and easier to use. If you find that your gels are drying out, it's a really good product to have to bring them back to life or just make them a little more malleable and easy to use."

"I'm going to use a little bit of Inglot Duraline in to my Sigma gel eyeliner... I mix a little bit of Inglot Duraline in with my Sigma gel, so now the trick is trying to get it as even as possible."

"I have this cupcake pastel Duo Chrome loose eyeshadow from Carla cosmetics and I'm going to mix that with a little bit of Inglot Duraline and I'm going to make a little liquid situation to put underneath that extension."

"Inglot Duraline is something that professional makeup artists have used in their kit for years and years. It's mainly to freshen up dried up makeup. It can also make all these different products one product, for example, if you want to make an eyeshadow into a lipstick, or an eyeshadow into mascara. You can mix it in with foundation if you wanted to. There are different bases, water based, alcohol based, airbrushing ones. These are products that do absolutely work. Yes, it does everything that people say it does. I have backstock of it because it's in my kit, it's in my regular makeup. It's everywhere because it is a must for professional makeup kits. I just love the Duraline one. I think it just works for everything."

"I'm gonna use a few drops of Duraline from Inglot, which is basically a mixing medium. That will make it a lot more easier and malleable. I'm putting one little drop of the Duraline into the color case directly, and I'll leave it to dry out before I put the lid on, and then just putting my brush in and making it into a paint, basically."
