The skin of the face is much more abundantly supplied with cholinesterase-containing nerves than skin elsewhere on the body. All the hair follicles on the chin and jowl have such specialized end-organs. The eccrine sweat glands on the face have nerves around the duct as well as around the secretory coil. Those around the duct are probably sensory afferent.
With the exception of the external genitalia, the face has more cholinesterase-containing nerves than the skin elsewhere on the body. Also, the tactile end-organs around the hair follicles there are more numerous and better differentiated than elsewhere.
