Related Smile Types
Social Smile
The polite, performed smile used in greetings and formal settings — mouth activates without full eye engagement. Social smiles are functional and friendly but score lower than Duchenne expressions on warmth metrics.
Closed-Mouth Smile
Lips stay together while corners elevate — a subtle, sophisticated expression common in editorial and formal portraiture. Can be genuine or social depending on eye engagement.
Nervous Smile
A tense, sometimes asymmetric expression combining smile mouth geometry with anxiety signals — raised brows, wide eyes, or tight jaw. Reads as uncertain rather than warm.
