Still, there is a definitely a trick to pulling off this blushing beauty look: mascara\u2014lots of it. "It bolsters the pink and creates contrast," added the pro.1. "If you're prone to schmutz, save concealer for after mascara," said Najor. To work the wand in at the roots and avoid smudging under eyes, the pro suggests using a Shadow Shield or holding a folded tissue against your lash line.

Then, "spike up" top and bottom lashes by wiggling the wand into the roots of your lashes and pulling out, said Najor. Reach for the inkiest formula possible, like Rimmel London Scandaleyes Mascara in Extreme Black, that boasts extra-intense black pigment and a dense brush designed to create lush, clump-free lashes.2. Even out your complexion with concealer or foundation to erase any areas of redness that could compete with your underliner, then rim lashes with a neon pink liner or pack on a pigment with a damp brush for more intensity. (If you don't have a pink eyeliner or pigment handy, try a creamy lip pencil like Rimmel London Exaggerate Lip Liner in You're All Mine or a bright blush instead.) Want to road-test other eye-brightening options? "Blue and purple are perfect for introducing color into your repertoire," said Najor.\n\tAdvertisement - Continue Reading Below\n\t\n\n3.

Using a black liquid liner like Rimmel London Scandaleyes Precision Micro Liner (the ultra-thin felt tip and ultra-black pigment make a smooth line a cinch), create a quick slash along the outer corner\u2014stretching the shape up towards the tail of your brow to make "eyes look larger and lifted," said Najor.
