The exact definition of the Duchenne smile is a bit technical, but we'll break it down for you. A Duchenne smile is a natural smile of enjoyment, made by contracting the zygomatic major muscle and the orbicularis oculi muscle. It’s often quite involuntary, and experienced during times of genuine happiness or enjoyment.
