Like with the aforementioned mascaras, these nourishing mascara primers deliver instant lash-lengthening, volumizing and overall fluttery-ness, along with long-term benefits.

It Cosmetics Tightline grabs lashes at the base for instant eye-opening effects. Unlike other primers, it's tinted black, so you could wear it on its own, or layer a mascara on top for even more drama. It's also infused with a dose of conditioning serum containing peptides, collagen, proteins and biotin to ensure lashes are healthy, full and lush.

Dior Diorshow Maximizer Lash Plumping Serum curls lashes and readies them for mascara application, resulting in a bright-eyed and bushy-tailed look, but what really keeps us coming back for more is the blend of breakage-preventing, growth-enhancing soy protein and plumping hyluaronic spheres.
