Eyeliner smudges so easily because the eyelids are the greasiest part of the face. Before applying makeup, reduce oily residue with an alcohol-free makeup remover. Then apply a light layer of foundation to even your base, and finish with a dusting of translucent powder over the lid. It will set the color and absorb oils throughout the day. TIP: Skip—or cut back on—putting eye creams on your lids pre-makeup to avoid slippery textures later.
Any type of hard line on the face needs to be done perfectly or not at all. Messy liquid liner makes people look older and harsher. If you have rounder eyes, opt for powder and gel liners that will smudge enough to create an almond-shaped contour. Fine pencils and pens are ideal for more elongated or oval-shaped eyes. TIP: Avoid dull or waxy points, and put pencils in the freezer for 30 seconds before sharpening.
Resist the urge to pull your lid taut when applying liner. When you let go, the line will look distorted. Instead, create your own eyeliner stencil by applying a piece of Scotch tape across your partially closed lid (press it on your arm first to make it less sticky). Then fill in the area below it, starting at the outer edges and moving inward. TIP: Keep eyeliner on the top lid three times thicker than liner on the bottom. And for extra staying power, use waterproof gel liners on the bottom lash line.
