Start at the inner corner of your brow, and with a light hand, etch a thin, subtle line at your brow base, working your way in towards the arch. Once you reach the arch, go back to the brow’s beginning to create flicks of “hair” following the natural direction of your brow hairs. Continue until you reach the end of your brow or where you’d like it to end. The magic spot is usually where an invisible line from the wing of your nose meets the tail of your brow bone.
As for the arch, use your pen to measure out the highpoint of your brow bone by angling it from the wing of your nose. Gently form your arch there. Work your way back into the brow with short strokes, keeping the pen at an angle in the direction of your brow. Repeat until you’ve reached a desired density. Using the spoolie, comb through your brows to fade ay harsh lines or edges.
