Smile guide
Learn how smiling changes facial warmth, structure perception, and camera impression, and when neutral expression can still work better.
A natural smile usually increases perceived warmth and approachability, which often lifts overall attractiveness in social contexts. This is why smile score and smile intensity often correlate with better first-impression outcomes in casual profile photos.
In some professional or fashion-style photos, neutral expression can preserve facial structure cues more clearly. If a smile becomes too tense or asymmetrical, your score can drop even though expression energy goes up.
Compare neutral, soft smile, and full smile under the same angle and lighting. Keep your head level and avoid changing camera distance between shots. This gives a cleaner read on whether expression or setup is driving the result.
Use smile analysis for focused smile metrics, then run expression impact to compare neutral, soft smile, and full smile in one workflow.
