1. Start With a Good Base
"I like to wipe off any excess oil on the eyelid and use an eyelid primer. Apply translucent powder to set primer on the lid or eyeshadow, then apply liquid liner. Priming lids makes sure they're oil-free and dry to prevent the liner from transferring back onto the lid."
2. Go Between Lashes
"I love using pen liners that are very fine (Charlotte Tilbury and Troy Surrat make great options) in between the lashes after so the lash line looks more defined."

3. Double Up on Products
"You can use a pencil first to outline the wings and even out the line easier. Then follow with liquid or gel liner."

4. Set It With Shadow
"I think two coats of eyeliner is better than one—and if you're doing a black line you should absolutely set it with black eye shadow."
—Michael Anthony, @manthony783
5. Then Dab It With Setting Powder
"You can always put a touch of setting powder over the liquid eyeliner with a foundation brush or concealer brush to make it stay put all day. Usually a setting powder slightly put on top is enough to do the job."
