Fake smiles can be performed at will, because the brain signals that create them come from the conscious part of the brain and prompt the zygomaticus major muscles in the cheeks to contract. These are the muscles that pull the corners of the mouth outwards.
Genuine smiles, on the other hand, are generated by the unconscious brain, so are automatic. When people feel pleasure, signals pass through the part of the brain that processes emotion. As well as making the mouth muscles move, the muscles that raise the cheeks – the orbicularis oculi and the pars orbitalis – also contract, making the eyes crease up, and the eyebrows dip slightly.
Lines around the eyes do sometimes appear in intense fake smiles, and the cheeks may bunch up, making it look as if the eyes are contracting and the smile is genuine. But there are a few key signs that distinguish these smiles from real ones. For example, when a smile is genuine, the eye cover fold - the fleshy part of the eye between the eyebrow and the eyelid - moves downwards and the end of the eyebrows dip slightly.
Scientists distinguish between genuine and fake smiles by using a coding system called the Facial Action Coding System (FACS), which was devised by Professor Paul Ekman of the University of California and Dr Wallace V. Friesen of the University of Kentucky.
With a fake, it's more in the mouth alone. Take the test below.

Well, everyone has mentioned the eyes, and yes with a genuine smile the eyes kind of twinkle and crinkle at the corners. But also in a real smile the ears kind of move up a little, because the whole face is involved, not just the mouth. Watch a small child smile, little kids always have genuine smiles because they haven't learned to "lie" with the face. the whole face lights up.

You can tell a real smile because you can see the smile in the eyes. You can see the love or the altruism underneath of the smile. Its really not at all about how it looks but more about how it feels when you see the smile. You can feel a real smile, a fake one you can only see.

A fake smile doesn't make it to your eyes. A genuine smile is accompanied by smiling eyes.

genuine smile is a smile that comes from inside you, but a fake smile is just the lifting of the corners of ur lips or to some ppl showing some teeth as not to offend some ppl by not smiling ^_^

A genuine smile comes from the heart, from happiness and joy.
A fake smile is just a mascerade, no real emotions involved.

Always check the eyes--Some people smile like a shark--their lips curl up but their eyes look dead
