Hyaluronsäure wird von Hautzellen gebildet und ist Teil des Bindegewebes der Haut. Die hauteigene Produktion von Hyaluronsäure nimmt jedoch mit dem Alter ab. Eine der Hauptfunktionen von Hyaluronsäure ist die Speicherung von Feuchtigkeit: sie hat die Fähigkeit, das 1.000- bis 10.000-fache ihres Eigengewichts an Wasser zu binden (d.h. ein Gramm bindet zwischen einem und zehn Litern).

Being a derivative of the skin’s own humectant glycerol, glyercyl glucosides facilitate epidermal moisturization. Dry, stressed skin shows significant reduced aquaporin channels. These channels control the transport of cellular water and other small solutes between and into cells. Thus, playing an important role in maintaining epidermal water balance. The most abundant aquaporin in the epidermis is aquaporin-3 (AQP3). Glucosylglycerol (Gluco-glycerol) stimulates the expression of AQP3 in epidermal skin cells and has been shown to stimulate the formation of aquaporin 3 (AQP3) in skin cells, thus increasing the number of aquaporins that control water transport in and out of cells.

APG Complex (short for Alkylpolyglucoside) is an extra mild cleanser. The `G` stands for Glucoside, which is a nature-derived surfactant. Surfactants are the active ingredients in cleansers that enable them to clean the skin by lifting and removing impurities. There are several different types of surfactant widely used in skin cleaning products. Anionic (negatively charged) surfactants are often used because of their great foaming properties, but Glucoside (which is non-ionic, with no charge) is proven to be particularly gentle on the skin.
