I’ve been using Bobbi Brown gel eyeliner ($24) for years. The black-as-can-be formula always stays put throughout the day, even out in the Texas heat. I like to layer my liner, and this is the first layer. The gel glides on, making for an easy application that will define eyes without pulling at the delicate skin and rubbing off lashes. After this, I go over the liner with powder or liquid if I’m in the mood for a smokier look, but the base is the most important. The only issue with the pot is that you have to carry around a brush to use it. In her latest collection “Perfectly Defined,” Bobbi gives us our favorite gel liner in pencil form, meaning I can apply anywhere, even the back of a cab (I really am an expert at makeup on-the-go). Now I can keep the pot at home and take this on the road! Bobbi Brown Perfectly Defined gel eyeliner at Bobbi Brown Cosmetics for $24.
