The real pièce de résistance — and pain in the ass to develop — was the brush, which is often overlooked by consumers, but as critical to any mascara as the formula. "A beautiful formula isn't any good if it's not spread appropriately on the lashes," says George. Well, lashes are ultimately just hair, thought Lynch. So, she and her team took inspo from hair brushes. "There's a paddle brush that smooths out the hair.
To ensure that the perfect amount of formula gets onto the brush, they made the wiper, a sort of internal drain plug in the tube, slightly tighter than that in a typical mascara. "The wiper is really important because it does what it says. It wipes off the product from the brush before you use it," says Lynch. "It's really important to get the exact ratio of product that you would want to optimize the formula on the lash.
Per our testers, they got everything Goldilocks-level just right. "It melts into the older mascara to save clumps from falling and allows me to stretch them out along the lash again," says Scott. "I was happy to see how it cut through clumps and separated lashes. It slicks over the older coat so lightly and stays workable so that you can fully comb through."
Lynch says that their internal testing found the ideal time to apply the refresher is about four or five hours after your. Then you just pull out the wand and coat lashes like you normally would. The formula dries in under a minute and can be used on top of pretty much any mascara — although it will work best on non-waterproof formulas, says Lynch.
