Glow & Glow Effect
Scientifically prove the glow effect of your skincare treatment through AI image analysis, consumer perception, and biometric measurements of facial attractiveness.
The client challenge
A premium skincare brand is launching a new illuminating serum and wants to scientifically validate its main claim: "Visible Glow Effect from the first application".
“Glow” is a subjective, multifactorial concept: brightness, skin tone evenness, subtle reflections, a “healthy” look. The brand needs objective metrics to differentiate its product from the dozens of existing “radiance” serums.
Identified challenges
- Objectify the subjective notion of "glow"
- Measure the visible effect from the first application
- Quantify the impact on perceived attractiveness
- Generate differentiating and defensible claims
Multidimensional measurement of radiance
Diverse Phototype Panel
Participants aged 25 to 55, with combination to dry skin.
Multi-measure Glow Protocol
Combination of AI image analysis, consumer perception, and biometric measures.
Photographic baseline
