What I Do: Ariana's Favorite Eye-Enhancing Makeup

"I used a pencil liner until I started experimenting with cream versions and now I'm totally devoted to this particular liner. The color stays put all day and has the intensity and manageability of a liquid. The waterproof formula smudges slightly only after a long night of dancing, which ends up coming off as a smoky eye. I like that I can wear this liner by itself for the days that I'm keeping makeup at a minimum by just drawing the top lash line a little thicker than usual."

"Mastering the art of lining with a brush isn't easy. My advice is to throw away the brush that comes with the cream liner — they're usually so small they're meant for American Girl Dolls. Invest in a brush with short, stiff bristles like this Clinique one. I dab it into the liner and run it along my lash lines with short strokes. Then I repeat the process for seamless results."

"I don't wear a ton of eye shadow during the day, and Shale is a subtle dusty purple color that makes me look awake but not overdone. I complement the look by dusting Shroom along my brow bone below my eyebrow. The neutral ivory shade is great for highlighting."

"This coveted curler is a beauty industry favorite and really does get every lash. I find it amusing when my boyfriend winces in pain as he watches me use it. I clamp down for a few seconds, release, and immediately apply my favorite waterproof mascara. I once tried blasting it with a blow-dryer for even more curl, but I almost torched my eyelid, so I don't recommend doing that!

"This mascara was my first big beauty splurge and now I don't know what I'd do without it. I find that waterproof formulas hold a lash curl better, even though they're tougher to remove at night. I love the jumbo-sized brush and the volumizing formula. That alone makes it worth every penny."
