Quizplus · Accepted Answer

Duchenne smiles are considered authentic because they involve the contraction of the orbicularis oculi muscle, which causes crinkling around the eyes. This is difficult to fake intentionally and distinguishes them from intentional or forced smiles. Duchenne smiles involve not only the corners of the mouth, but also the eyes and other facial muscles.
