"Smile in eyes" is a term used to describe the crease that forms around the eyes when someone smiles genuinely. This crease, also known as crow's feet, is a sign that the smile is authentic and involves the muscles around the eyes.
A genuine smile often involves both the mouth and the eyes, while a fake smile might only involve the mouth, leaving the eyes seemingly unmoved. The involvement of the eyes in a smile is considered a strong indicator of the emotion's authenticity.
Here are some points to consider:
- Eye smiles in K-pop: The term "eye smile" is popular in K-pop culture, referring to the distinctive crescent shape that appears around the eyes when someone smiles. It's often associated with specific idols known for their eye smiles, adding to their charming persona.
- Duchenne smile: In psychology, a smile involving both the mouth and eyes is called a Duchenne smile, named after the 19th-century scientist who studied facial expressions. It's considered a genuine and spontaneous smile, often associated with happiness and positive emotions.
Therefore, "smile in eyes" refers to the physical expression of genuine happiness, characterized by the creasing around the eyes when someone smiles.
