What to look for

1. 1The corners of the mouth rise.
2. 2The cheeks lift; the eyes may narrow.
3. 3Small creases may appear beside the eyes.

The upward movement at the mouth corners is a useful starting point. Then compare the cheeks and the area beside the eyes with the neutral example. A change across several regions gives you more to observe than visible teeth alone.

Look at the neutral face for a moment. On the expression example, trace the movement from each mouth corner toward the cheek. Switch faces and look for the same combination rather than memorizing one smile.
