Glossier’s New Pro Tip Liquid Eyeliner’s Staying Power Is No Joke, and Here’s the Proof

I was floored at the liner's staying power. To see how budge-proof it really was, I ran swatches of the liquid formula under running water. I was pleasantly surprised at how it never bled or flaked, despite being submerged in water for a solid two minutes.

I began rubbing the lines to see how it would break down, and found that it still wouldn't come off. I ultimately had to use an oil-based cleanser for removal. (The brand recommends using its Milky Oil ($12).)
