You’d be forgiven for thinking that you don’t really need a waterproof eyeliner – after all, you probably don’t actually place your face in water on a regular basis throughout the day. However, there’s a whole host of factors that threaten to smudge your painstakingly applied feline flicks in the blink of an eye – humidity, sweat, oily lids and accidentally rubbing your eyes included. When you’ve spent half the morning trying to make those points symmetrical, you may as well ensure they stay put for the rest of the day.

But while plenty of liners claim to stick with you through thick and thin, the reality is that many fall short of expectations, leaving you with panda eyes by lunchtime.Chief beauty ambassador Maggie Ford Danielson also the daughter of one of the company’s founders) says the Roller Liner seeks to solve ladies' lining dilemmas when trying to draw that perfect dark trace above the lid: “Most liners are shiny, this one’s matte.” The new product is available at the pop-up as are other Benefit products including roller mascara, T-shirts that say “Bene-babe” and cute glitter makeup bags with fluffy pink pom-poms. 

Known for its sexy retro style, Benefit was founded in 1976 in San Francisco by twin sisters Jean and Jane Ford, with an irreverent take on beauty, especially when it came to packaging. They sought to create modern formulas with vintage appeal, and as Danielson told us at the opening, their aesthetic has always made for a perfect match in L.A., where women are a little bolder with their makeup looks. From pin-up girls to burlesque and rockabilly chicks to gals with rock & roll flair, the liquid line and cat eye seems to be favored on West Coast faces, so it makes sense to roll out this one in the heart of a trendy shopping area like Melrose.

The space housed the very first Johnny Rockets cafe, which went on to become a global chain.That’s why we’ve tested all the most-hyped formulas on the market, to bring you the ones that really hit the mark.These hardcore formulas will withstand pretty much anything you throw their way, from a sweaty morning commute to a high-humidity holiday, and even that time you ‘got something in your eye’ at the end of Queer Eye.
