Emotional Impact & Relaxation
Scientifically validate the wellness and relaxation claims of your cosmetic treatments through physiological and behavioral measurements.
The client challenge
A premium cosmetics brand wants to launch a new at-home spa treatment positioned on the benefits of intense relaxation and stress reduction.
To stand out in a saturated market, the brand needs robust scientific evidence to support its marketing claims and convince retailers and demanding consumers.
Identified challenges
- Objectively validate the product's relaxing effect
- Quantify stress reduction in a measurable way
- Compare performance vs. competing products
- Obtain data usable for regulatory claims
A rigorous methodology
Multi-country recruitment
Qualified panel of regular premium cosmetic treatment users.
Recruitment criteria
- Women aged 25-55
- Regular users of spa treatments (2+ times/month)
- Upper socio-economic status with a beauty budget > €100/month
- No contraindication to EEG/GSR measurements
Experimental Design
Double-blind protocol with product randomization.
Baseline
5 minutes of rest to establish baseline measurements (EEG, GSR, heart rate)
Product application
Self-application of the treatment according to instructions, filmed for Facial Coding analysis
Wear phase
15 minutes of wear with continuous EEG and GSR measurements
Post-application
Hedonic questionnaire + declarative measures via conversational avatar
A multimodal arsenal
EEG - Brain Activity
Measurement of brain waves to quantify states of relaxation (alpha waves) and stress (beta waves).
GSR - Electrodermal Response
Skin conductance as an indicator of autonomic nervous system activation.
Facial Coding
Automatic analysis of facial micro-expressions during application.
Conversational Avatar
AI-guided interview to gather declarative perceptions.
Actionable insights
Brain relaxation
+42%Significant increase in alpha waves (8-12 Hz) during the application phase, confirming a state of deep relaxation.
Stress reduction
-87%Drastic decrease in skin conductance, an indicator of a drop in sympathetic nervous system activation.
Positive emotions
94%Positive facial expressions (pleasure, serenity) dominant throughout the entire application.
Purchase intent
89%Exceptional purchase-intent score, confirmed by the analysis of the conversational avatar's verbatims.
