There are beauty secret weapons, and then there is Stila's Stay All Day Waterproof Eyeliner.

Ever since it first debuted many seasons ago, the felt-tipped black pen has become a staple backstage at fashion shows and everyday life alike, thanks to a practically permament formula that lasts through essentially anything.

Thunderstorms, pool parties, sweaty concerts, showers...your cat eye will survive. 

To celebrate the fact that Stila's finally rolled out a full colorwheel of hues, we had to put the new set of inks through the ulitmate tests. See how they did in the gallery!

The Color: Cobalt

What I did while wearing it: Went to to the beach, got caught in a thunderstorm, showered, had a mini-Netflix marathon.

How long it lasted: It stayed on pretty well, for the most part, with just a little fading after I showered. By the end of the day, the color had dimmed to a baby blue for a cool '60s look.

Any other pros/cons: You have to press the felt tip down every so often to deposit color, which I found to be a bit tricky. I also found it was necessary to use a dark liner on my upper inner lid to make the color really pop. (I used Rimmel's Scandaleyes Eye Shadow Stick in Blackmail.) That being said, I definitely made the coolest cat eye of my life with this liner.

The Color: Intense Black

What I did while wearing it: Had my outdoor birthday party at a bar, which quickly morphed into dinner, more drinks, and a late-night dance party.

How long it lasted: Stila's not kidding when it says "all day" (or in my case, all day into the night...). My black cat-eye stayed on despite the 85-degree temps, lasted throughout dinner, and, with a brief mini touch-up around 10 PM, looked pretty much perfect past midnight.

Any other pros/cons: I liked the super thin tip, and the fact that you can layer on for more intense color. Unlike many supposedly waterproof eyeliners, this one truly doesn't budge--even during a sweaty dance-off. You definitely need to know what you're doing though, because the fact that this formula is SO waterproof, it means that any little mistake can be tough to remove.
