Objectives
Natura Bissé, a company specializing in skincare product development, aimed to initiate a blind randomized, placebo-controlled study involving a cohort of healthy volunteers. The objective was to investigate the impact of their products on well-being levels when applied during a spa treatment. 30 volunteers completed questionnaires both before and after the treatment and a control session. Stress levels were assessed through salivary cortisol tests, and brain activity (EEG) was measured before and after the sessions. They enlisted the services of Starlab to assist in designing the study, acquiring and analyzing EEG data throughout the research, and providing support in the composition of the scientific article.
Starlab’s role: EEG analysis. We co-developed a protocol for this study, behavioral and electrophysiological data (EEG and ECG) were acquired by Starlab’s staff. Data analysis delivered different biomarkers based on:
Valence: defined in the pleasure-displeasure continuum as being more or less positive (Barrett et al., 1999). It is calculated as result of Starlab’s internal work based in the representation of emotions in a 2D space of valence and arousal (Russell et al., 1980; Frantzidis et al., 2010).
