Genuine Smile

A Smile is really contagious. You surely receive a smile in return from the person you smile at. However, sometimes, fake smiles are also exchanged as a formality or avoiding the other person letting down.

It's very important to know which facial muscles are involved that makes the difference between a fake and a genuine smile.

A thin band of Zomgatic muscles on both side of face arising from Zygomatic bone i. e. near ears and merging into Orbicularis Oris (circular muscles around mouth) and skin of mouth corners also contracts and pulls edges of lips upwards while smiling.

When we watch a face with genuine smile; it definite does a magic. A genuine, warm and friendly smile originates from the bottom of heart and spreads all over the face. Telling sign of it are crinkled eyes, crow's feet in area between eyes and ears, no signs of tension on forehead and no furrowing of eyebrows.

Emotional centers inside brain controls movements of facial muscles. Originality lasts longer like a lingering fragrance of blossom. Same principle applies to expression of emotions too. That's why a genuine smile appears and fades away gradually. On the other hand, crocodile tears don’t last longer so does the fake smile.

One has to put lot of efforts in mimicking a genuine smile at best by pulling back edges of lips forcefully for showing teeth while keeping eyes wide open. No crinkling or crow's feet appear near eyes. Fake smile appears shallow and it drifts away quickly as if it is accidentally or purposefully put on face.
