How many muscles are used by us to smile?

Dear student,
Please find below the answer:

Although it is not clear how many muscles we use to smile. This is for sure that we use more muscles in frowning than in smiling. The number varies form one report to other. Therefore there is no surety about the number of muscles exactly involved.

  • According to doctors, we use only four muscles to smile.
  • Some claim it takes 43 muscles to frown and 17 to smile, but open Aunt Midas' chain letter and you might be surprised to learn it takes 26 to smile and 62 to frown.
Hope this clears your doubt.
Regards.
