Explanation

It takes 17 muscles to smile and 43 muscles to frown. Smiling primarily involves zygomaticus major and minor muscles pulling the mouth corners upward, plus orbicularis oculi for genuine eye crinkling. Frowning requires more muscles: corrugator supercilii draws eyebrows together, procerus creates vertical wrinkles, and various depressor muscles pull the mouth down.
