Applying a stripe of eyeliner sounds simple, but getting that pigment to really pop can be tricky. That's why Rivera recommends you first outline the line along the upper lash line with a lip brush and waterproof liquid concealer in a light shade for "a more intense colour payoff."
First, he blended the blue-and-white duo-chrome shadow across the entire lids with a blending brush before using a bullet brush to sweep the mint hue atop the concealer outline. This is where your personal preference comes in: you can either intensify the look with the deeper green or lighten it up with the pale pistachio shade (Rivera did a mix of both).
The best part about this makeup look? It's pretty easy to course correct: "Use a concealer and concealer brush to go back in and clean-up or sharpen your coloured liner looks," he said. "It's easier to erase than draw."
