Craniofacial

The forehead, scalp, and face carry many sweat glands, so this area can sweat readily with heat, exertion, or emotion. The term groups the skull and facial regions into one descriptor. It appears most often in the context of head-and-face sweating, which is hard to conceal because the area is exposed. It helps name where a sweating pattern is concentrated. Because the head is so visible, craniofacial features tend to draw attention in social settings. The word combines roots for skull and face, which is why it spans both. It is used in fields beyond sweating, such as descriptions of head and facial structure. In the sweating context it marks the head-and-face distribution specifically. Its exposed location is a large part of why sweating there is so noticeable.

Craniofacial sweating refers to sweat centered on the head and face, such as a persistently damp forehead and scalp. Because the region is exposed, this sweating is harder to hide than sweat under clothing, which is part of why the term comes up so often. In a phrase like craniofacial hyperhidrosis, the word pins the heavy sweating specifically to the head and face.

It names the region in craniofacial hyperhidrosis, sweating focused on the head and face, which can overlap with gustatory sweating and flushing.
