Jan 27, · Full facial smiles require more muscle movement then smaller smiles. There are 36 facial muscles used to create facial expressions, but only a few are used to smile. Different types of smiles, such as so-called fake smiles, require a different number of muscles. The number of muscles used to smile varies.
Some claim it takes 43 muscles to frown and 17 to smile, but open Aunt Milda's chain letter and you might be surprised to learn it takes 26 to smile and 62 to frown. And some naysayers claim it's quite the opposite, that in fact it takes more muscles to smile than to frown.

There are twelve muscles that help the face to smile, a couple of them are, the Zygomaticus major and minor and the Levator anguli oris. There are of course 9 more that are included in the smile process.
