OBJECTIVE
It is well known that skincare products can promote well-being. However, this impact is difficult to determine objectively, as well-being is a highly subjective concept but also a complex one encompassing various dimensions. This project involved studies designed to examine, how the use of three face creams (named serenity, energy and joy) is associated with internal states of well-being that align with the specific objectives of each cream.

METHOD
These studies were carried out in a specific laboratory (well-controlled environment) with a panel of 45 participants. The well-being dimensions were assessed through a combination of physiological measures, non-conscious psychological measures and behavioral measures. Moreover, each study was conducted both after a single use and after a twice-daily use for four weeks.

RESULTS
Data analysis, across the various measures, made it possible to rigorously examine the well-being effects associated with the use of each cream: reducing stress and promoting calm (‘serenity’ cream), boosting vitality and delivering an influx of positive energy (‘energy’ cream), and fostering joy and a sense of happiness (‘joy’ cream). Furthermore, these results were maintained after four weeks of use, ruling out concerns about a potential “habituation effect”.

CONCLUSION
Drawing on state-of-the-art scientific methods and expertise, this project shows that it is possible to objectively and precisely determine the extent to which product use is associated with positive effects on well-being.
