It was an idea we got from Elizabeth Sulcer in her Top Shelf After Dark—the nerve to take a lip pencil, direct it about four inches upward, and use it on your eyes, too. "If a product is great for one thing, you've got to get creative," Elizabeth said. "Ultimately it's all going on our face, right?" The pencil in question, MAC Stone, appeared again a couple weeks later for an encore performance at Ryan Roche's fall runway show. Makeup artist Romy Soleimani deftly blended Stone with a couple other MAC shades, like Brick (lip) and Coffee (eye), for a barely-there reddish wash of color. Gemma Smith-Edhouse did something similar with Guerlain Bois des Indes at Maryam Nassir Zadeh. What's the saying again—"thrice lipliners are trending?"

Something like that. But it makes perfect sense, and exploits the full potential of your favorite lip pencil—in its primary function, lip liner does exactly what it says it does. Why not maximize its potential? Bois des Indes in particular is a great starting place: tawny, nudey, rosy, and blendable enough to add warmth to both lips and eyes without reading like LIPS and EYES. On the more dramatic side of the spectrum, eyes can be lined and smoked, and lids can be washed out à la the '90s. Either way, it looks entirely fresh.

A word of warning: Keep an eye (pun prudently intended) on your pigments. More vibrant shades, depending on the chemical makeup, can stain eyelids if applied too heavily. And it goes without saying—always make sure the liner in question is wiped clean before each use. If any irritation happens, wash it off immediately. Actually, exercise corneal caution in general. But you already knew that, because you're smart. And very practical. Why use two products when you can use one?
