BROW TRICK 1: Just like a low ceiling can make a room seem smaller, straight brows have a similar effect on your eyes. “To expand the eye area, I brush up the brows and tweeze in a slight arch,” says Pati Dubroff, a celebrity makeup artist. She also recommends cheating the arch just past the iris’s outer edge.
BROW TRICK 2: Brow colour can also make the eyes look more open, says makeup artist Stevi Christine. On dark brows, she brushes a tinted gel slightly lighter than the natural colour from the inner corner through the arch. She then blends a powder that’s slightly darker from the arch through the end to add fullness and length – which makes your eyes appear more wide set. On light brows, she suggests combing a powder two shades darker than your natural colour through the entire length to define, but not darken them significantly.
