RAU Stem Cell Concentrate"  contains  not only an extract of the apple stem cell , but also  whole stem cells of  the thistle.  They contribute  to the  restructuring  and  protection of the skin  on several levels. Stem cells are rich in lipids, amino acids, polyols, polyphenols and sugars and act on the epidermal and dermal level as well as in the intermediate matrix. 
In the epidermis, the stem cells promote the growth of new skin cells and  thus accelerate skin renewal ,  damaging and oxidative radicals are intercepted  and  inflammatory processes are minimized.  Special mediators and molecules, responsible for the communication and connection between epidermis and dermis, are protected and stimulated. At the dermal level,  collagen  synthesis is stimulated and proteoglycans are stimulated (  premature skin aging can thus be counteracted decisively. synthesis is strengthen the skin matrix ).
