How does a model smile?

A model smiles by engaging their facial muscles, particularly the zygomaticus major, which lifts the corners of the mouth. They may also incorporate their eyes, creating a genuine expression known as a "Duchenne smile," where the eyes crinkle slightly. Lighting and angles can enhance the smile's impact, making it look more flattering in photographs. Ultimately, a model's smile combines technique with an authentic sense of confidence and personality.
