Water is an essential component of every type of human organ and tissue. However, although the quantity in which it is found varies in the body’s different regions, hydration status is one of the parameters upon which our bodies’ vitality and functionality depend.
Maintaining a good level of hydration is linked not only to skin that is youthful in appearance but also to the presence of special proteins called aquaporins, which form channels in the cell membranes to regulate the flow of water from the deeper layers of the epidermis all the way up to the stratum corneum.
This test makes it possible to evaluate, directly on whole skin cells, the increase in expression of aquaporins, following short- and long-term treatments on an experimental model that mimics the physiological condition of cells, without damaging the original architecture of the cellular structures. This method is able to provide an analysis of actual skin hydration.
