Private face-region analysis in CIELAB — radiance, calmness, oil balance and the eye area. Runs on your device.
Metrics are computed in CIELAB and calibrated against your own sampled face regions where possible. The pins mark areas of local variation: visual features only, not diagnoses of acne, lesions or conditions.
Hydration and fatigue are not measured. A camera can't read them. Eye area, radiance, oil balance and calmness describe visible appearance under the captured light. Patch-test products; see a dermatologist for anything persistent or changing.
