Cheek line
The upper edge of a beard across the cheek, running from sideburn to moustache.
Also: cheek line (beard)
The cheek line marks where beard growth stops on the cheek. Some men keep it natural, trimming only stray hairs above it; others cut it low and straight for a sharp look. A lower cheek line makes the face look slimmer, a higher one fuller. Barbers shape it with a trimmer or a straight razor, often with a hot towel first, as is traditional in Turkish barbershops.
