Related Smile Types
Duchenne Smile
The gold standard of genuine expression — Duchenne smiles activate both the mouth (zygomatic major) and eyes (orbicularis oculi). They score highest on Smile Tracker and read as authentically warm in human perception research.
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.

Social vs fake smile?
