A cult classic and backstage staple at runway shows and red carpets alike, Dior's plumping formula was one of the OG mascara primers to hit the market, and the love for the brand's iconic product is still going strong. Featuring a nourishing, oil-based serum in addition to their exclusive Pure WhiteTM complex, this little white tube delivers the exaggerated extension, thickness and curl that you crave — sans extensions or falsies. And since there's nothing better than killing two birds with one stone when it comes to your beauty routine, the product does double duty as both a pre-mascara eyelash primer and a luxurious overnight leave-in. The perks: less fallout, a denser lash line, and intensified color and curl over time.

Extension-building microfibers and a creamy, ultra-conditioning formula is what makes this eyelash primer from Lancome a stand-out in the beauty world. Consistently at the top of the pack when it comes to rave reviews and rankings, this two-in-one primer pampers lashes while you sleep and streamlines your morning mascara application with vitamin-charged conditioners that create a smooth and lengthy canvas.

Known for their skin-loving and cruelty-free formulations, it comes as no surprise that Tarte's Opening Act Lash Primer provides extension-like results in addition to an impressive (not to mention pronounceable) ingredient list. Olive esters, beeswax and cellulose work to naturally soften, smooth and thicken lashes for sultry, super-sized results. Our suggestion? Apply this eyelash primer prior to one (or three) coats of one of the brand's award-winning mascaras. The Lights, Camera, Lashes 4-in-1 Mascara, $21, is a beauty editor favorite.

If your lash line has been feeling comparatively sparse or fragile as of late, this ophthalmologist-tested formula from Clinique might be the key to a fuller, flirtier flutter. Just a few swipes of this polymer-packed potion expertly extends the luscious look of your day-to-day mascara application, while simultaneously moisturizing brittle and tired lashes. A simple upward swipe through your fringe powers your mascara through high-stress meetings and your favorite E.O.D. spin class — no flakes or streaks in sight.

Consider this do-it-all eyelash primer the Thelma to your curler's Louise. The ultimate power couple, this hydrating mascara base from Shiseido preps and maintains lashes for a sumptuously dramatic look that stays put all day. First use your curler (this one by Shiseido is a celebrity and makeup artist favorite) and then work the primer's thirst-quenching formula from roots to tips. The oil-infused product sets the curl of your lashes while intensifying length and volume.
