You use a face primer before makeup application, a base coat before your nail polish color and a styling product before actually styling your hair, so why wouldn’t you follow that same principle when it comes to your mascara? Yes, mascara primers are a thing, and yes, they’re 100% worth the extra step in your makeup routine. Mascara primers like the L’Oréal Paris Voluminous Lash Primer have many purposes — the main one being the ability to boost your lash look with a single swipe. The white-colored formula helps build dramatic volume and length to your eyelashes, even before you add a touch of mascara. And bonus, this one conditions your lashes over time to soften and nourish them, a must if you’re a daily mascara wearer. How to Use a Mascara Primer (Hint: It’s Really, Really Easy)STEP 1: Start With Clean, Makeup-Free LashesApply your eyelash primer right before mascara application in your normal makeup routine. Working one eye at a time, be sure to thoroughly coat your lashes in the primer for an even, volumized look. For more noticeable results, we like to go in with two coats of primer. STEP 2: Apply Mascara Before It DriesApply your mascara of choice on top (we like the L’Oréal Paris Voluminous Original Volume Building Mascara), before the primer fully dries — this is why you want to work one eye at a time. Doing so will help keep your lashes clump-free. And that’s it; two steps is all it takes to get noticeably fuller and longer-looking lashes with the Voluminous Lash Primer by L’Oréal Paris. Read More:How to Safely Remove Mascara From Your Lash ExtensionsThe Drugstore Mascara Will Give You the Doe-Eyed Lashes of Your DreamsHow to Apply Fake Eyelashes, According to a Lash Pro
