Related Smile Types
Open-Mouth Smile
Teeth visible with separated lips — high-energy, approachable expression that broadcasts warmth. Open Duchenne smiles typically achieve the highest Smile Scores.
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.
Asymmetric Smile
One side of the mouth elevates more than the other — common and often charming. Mild asymmetry is universal; pronounced asymmetry may indicate muscle habit or neurological variation.
FAQ — Closed-Mouth Smile
Can closed-mouth smiles be Duchenne?
Yes. If eyes crinkle genuinely, it's a Duchenne smile regardless of mouth opening.
Why do closed smiles score lower sometimes?
Less visible corner elevation and mouth aperture can reduce measured warmth even when genuine.
