“Your brows are totally unique to you—just like your fingerprint—so your ideal shape depends on your individual features, including your eyes and nose,” explains Bailey. “Before you do any tweezing or filling in, you’ll want to know exactly where your brows should start, arch and end,” he adds.
To identify your starting point, Bailey suggest grabbing your favorite brow pencil and placing it upright against your nose. “Follow a straight line up from the dimple of your nose to the front of the brow and make a mark. This is your starting point and will help slim your nose and balance your eyes.”
Next, to find where your arch should be, take the same pencil and hold it diagonally from the outer edge of your nose across the center of the eye and make a mark. “Say hello to your arch! This is where your brow is naturally at its highest,” says Bailey. “A little definition here can lift your whole look.”
