A good trim is just as essential to your brow upkeep as tweezing is. "Every brow, no matter how thick or thin, will need to be trimmed from time to time," explains Bailey.
"Trimming your brows is like trimming your bangs: It sounds easy, but often ends in disaster," quips Bailey. His tips for getting it right? "Take a clear gel and brush the brow hairs upwards towards the hairline and out towards the temple. Let the gel dry completely, then only trim the ends that are sticking too far out past your desired shape."

"Brows bring balance and proportion to your face and eyes, so it's important you use a mirror where you can see both of them," he explains. "AVOID tiny magnifying mirrors, because you can only see a field of tiny hairs versus the actual shape and what it's doing for your entire face.
"Always use natural lighting," says Bailey. "If possible, take a mirror you can prop up and tweeze near a window with even lighting on your face."

Pro-tip: "Use a micro liner to fill in your brow into the desired shape before you remove any hairs, so you can see which ones need to go and which ones need to stay," advises Bailey. (Obviously, the Benefit Precisely, My Brow Eyebrow Pencil, $24, is perfect for this job.)
