An eyebrow pencil may be the answer to the arches of your dreams. Whether you’re just looking to shape them a little or build your brows from the ground up, the makeup bag staple can handle it all. We spoke with Joey Healy, celebrity eyebrow specialist, for his expert tips on how to fill in your brows at home. His expert insight, ahead. Step 1: Create a Brow RoadmapThe first step in filling in your arches with an eyebrow pencil is to create a “brow roadmap,” or the areas of your brow in which you’ll be filling in with a tweezer and a pencil. The three key points of your brow, says Healy, are the “front” of the brow (the side closest to your eye), the “arch” and the “tail.” “You can determine the front of your brow by aligning the tweezer from the bridge of  your nose to your brow bone — and then make a tiny mark where they meet,” he says. To determine where the tail will end, align the tweezer from the corner of your nose closest to the brow you’re working on to the outer corner of your eye. Then, use this imaginary line to mark where your tail should end.”As for the arch? “You want the arch to be two-thirds of the way out from the front.”Keep in mind that you don’t want to create “any hard outlines,” which Healy says works for a drawing, but not your brows, otherwise they may look too harsh. Insead, make a really fine mark with your eyebrow pencil and don’t worry — practice makes perfect.Step 2: FillOnce you've created a brow roadmap, you can begin filling in. "Within the guidelines, use small pencil strokes in sparse areas, and use your spoolie to brush to blend out harsh lines and create an even appearance," says Healy. The pro recommends using a light hand and “starting with a lighter shade and building up the product,” so that it doesn’t appear too dark — unless that’s the vibe you’re going for.  Not sure which eyebrow pencil to purchase?
