Under-Eye AreaHow AI measures this feature and photo tips
The under-eye region — tear trough, orbital hollowing, and puffiness — is a primary age signal. Dark circles, bags, and hollowing affect youthful-energy scores independently of bone structure.

- ✦Fine lines (crow's feet proximity)
- ✦Light reflection and shadow
Analysis & Photo Tips
- 📸Soft front lighting reduces under-eye shadow
- 📸Sleep and hydration affect puffiness
- 📸Avoid overhead light that deepens troughs
- 📸Minimal under-eye makeup for accurate analysis

Skin Quality
Skin texture, tone evenness, and luminosity influence perceived age and vitality in AI analysis. While not a geometric landmark, skin signals feed youthful-energy scoring and overall impression.
Midface
The midface spans from the brow ridge to the nose base, housing the eyes, cheeks, and nose. Midface length and compactness strongly influence perceived age — shorter midfaces often read younger.
Facial Thirds
Classical proportion divides the face into three equal vertical zones: upper (hairline to brows), middle (brows to nose base), and lower (nose base to chin). Deviations signal unique character and affect harmony scores.
FAQ — Under-Eye Area
What causes under-eye circles?
Genetics, thin skin, pigmentation, vascularity, fatigue, and age-related fat redistribution all contribute to under-eye darkness.
Do under-eye bags affect age estimation?
Yes. Puffiness and hollowing are weighted signals in AI age models alongside wrinkles and skin texture.
Can lighting hide under-eye issues?
Fill light at eye level reduces trough shadow, but also obscures true depth — use consistent lighting for comparison.
