When talking eye makeup, your crease "refers to the area where there's a natural fold or indentation in the skin when your eyes are open," says Hughes. Typically, darker eye shadow colors go in the crease, in order to create depth.

Hughes suggests thinking of this area as the small, sideways V-shape that wraps around the inner corner of your eye (so, the side closest to your nose). FYI, this is where any kind of under-eye circles or shadows tend to be the darkest, which is part of the reason why using light eye makeup colors here works well; they brighten the entire eye area.
Like its counterpart the inner corner, the outer corner is also a small, V-shaped spot, but refers to the area only above the eye, not below (from just underneath the brow bone to the lash line). This is where you'd typically apply darker eye shadow colors, especially if you're going for a smoky or dramatic eye makeup look, says Hughes.
Quite literally, this is the bone under your brow. "If you place your finger under the arch of your brow, you'll clearly feel it," says Hughes. As with the inner corner, this spot is perfect for any kind of light eye shadow color, which make for a lifted appearance.
