In recent years the trend in cosmetic communication has been increasingly to stress the idea of “ageing well” rather than to pretend to “slow or stop” the skin ageing process. Quantitative measurements of Quality-of-Life parameters and Well-Being concepts have emerged as new methods and claims addressed to consumers.
In this way, we have developed a specific method named “mirror test” which is able to apprehend cognitive dimension.
It is to confront a subject to its own reflection. This confrontation is ecologically relevant for cosmetic studies as it corresponds to a natural daily situation for subjects. Moreover, such a confrontation is a potent psychological trigger endowed with a significant emotional load as it activates actual psychological problematic regarding self-conception and physical self-acceptance. As such, this confrontation acts as a mild stressor, allowing the measure of various parameters related to stress response.
