Eyebrow arch
The highest point of an eyebrow, where it turns from rising to falling towards the tail.
Also: brow arch, arch
An eyebrow has a head near the nose, an arch at its highest point and a tail at the outer end. Brow shapers often place the arch above the outer edge of the iris, though natural arches sit anywhere along the brow. A high arch gives a lifted look; a soft angle is gentle; a straight brow has almost none. Threading, tweezing, waxing and brow pencil all work by adjusting where and how high the arch sits.
