The glabella, is the skin between the eyebrows and above the nose. It also refers to the underlying bone which is slightly depressed, and joins the two superciliary ridges. It is a cephalometric landmark that is just superior to the nasion.
The term is derived from the Latin glabellus, meaning smooth.
The skin of the glabella can be used to measure skin turgor in patients suspected of being dehydrated by pinching it between the fingers and lifting it gently away from the underlying skull. The skin of dehydrated patients tends to remain extended (“tented”) rather than promptly regaining its normal shape.
