We say:
Another Face of Peace...and look at this one! It's a "Duchenne Smile"...where both sides of the face fire at the same time, and grab the eyes and fill the face...a Real Smile :)

wikipediea explains:

The "Duchenne smile", after the researcher Guillaume Duchenne, is the most studied, and involves the movement of both the zygomaticus major muscle near the mouth and the orbicularis oculi muscle near the eyes. It is believed that the Duchenne smile is only produced as an involuntary response to genuine emotion, and is therefore what one could call the "genuine" smile. Due to the involvement of the muscle near the eyes, it is sometimes said that one can tell whether or not a smile is "real" by whether or not it "reaches the eyes".
