The corrugator supercilii muscle is a small,[1] narrow,[citation needed] pyramidal muscle[1] of the face.[citation needed] It arises from the medial end of the superciliary arch; it inserts into the deep surface of the skin of the eyebrow.
It draws the eyebrow downward and medially, producing the vertical "frowning" wrinkles of the forehead. It may be thought as the principal muscle in the facial expression of suffering. It also shields the eyes from strong sunlight.
