6 Stila All Day Waterproof Liquid Eye Liner, $28
USING IT: I had to use a light hand with this felt-tipped brush – it was slightly rough against my skin but not painful. The firm tip made it easy to draw straight lines, and I liked that it didn’t need any layering for intense black lines. STAY-ON POWER: Smudged a little and transferred slightly to eyelid creases but needed no touch-ups. It was also fairly easy to remove.
