buttery, oh-so-blendable formula! This liner (which I used as a shadow, all over the lid, zero primer) stayed put through a brutally hot workout, a sad movie, AND a night’s sleep (I know, I know — wearing eye makeup to bed is some rookie BS, but I just had to see how long this product would last). Safe to say this bb has *staying power*. The copper-penny rosiness is a perfect compliment to my signature red lip, and as mentioned, functions just as well as a shadow as it does a liner. Even used a touch to highlight my Cupid’s bow. Love love love!
