Asymmetric SmileTraits, photo tips, and Smile Score impact
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.

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.
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.
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.
FAQ — Asymmetric Smile
Is asymmetric smile normal?
Yes. Most people have some smile asymmetry. Pronounced cases may reflect dominant-side muscle habit.
Does asymmetry lower Smile Score?
Symmetry is one component. A warm asymmetric Duchenne can still score highly.
