What Muscle Is Used in Smiling

The act of smiling is a complex interplay of various facial muscles, each with a specific role in shaping this universal expression of happiness. The primary muscle used in smiling is the zygomaticus major.

Your orbicularis oculi muscles play a role in forming genuine smiles by causing eye crinkling. Additionally, muscles like levator labii superiors, buccinators, depressor anguli oris, and the mentalis muscle all contribute to the subtleties of a smile. Understanding the intricate actions of these muscle used in smiling unveils the anatomy behind this heartwarming expression.
