Found a brief FACS with sample images at http://www.cs.cmu.edu/afs/cs/project/face/www/facs.htm

Before you understand FACS, it is important to know the basic face features.


GLABELLA---> Area of the forehead between the eyebrows.
ROOT OF NOSE---> The beginning of the nose between the eyes; also called the nasal root.
EYE APERTURE---> The degree to which the eye is open; the eye opening.
EYE COVER FOLD---> The skin between the eyebrows and the palprebral part of the upper eyelid (the part that contacts the eyeball), which folds into the eye socket.
LOWER EYELID FURROW ---> A place below the lower eyelid where a line or wrinkle may appear. A line or wrinkle may be permanently etched into the face; if so, it will deepen with certain AUs. If not, it should appear when these AUs are contracted.

INFRAORBITAL FURROW ---> A place where a line or wrinkle may appear parallel to and below the lower eyelid running from near the inner corner of the eye and following the cheek bone laterally.

NOSTRIL WINGS ---> The fleshy skin of the side of the nose that forms the outside of each nostril.

NASOLABIAL FURROW ---> A place where a line or wrinkle may appear which begins adjacent to the nostril wings and runs down and outwards beyond the lip corners. In some people it is permanently etched in the face; if so, it will deepen with certain AUs. If not, it will appear on most peoples' faces with certain AUs.

PHILTRUM ---> The vertical depression in the center of the upper lip directly under the tip of the nose.

CHIN BOSS ---> The skin covering the bone of the chin.
SCLERA ---> The white part of the eyeball.
