Stendo® as an ENDOthelial STimulator. The endothelium is a tissue made up of cells lining the inner wall of all vessels, from the largest to the smallest, whether blood or lymphatic. It guarantees the efficiency of a 170,000 km network, which is essential for the nutrition of our cells, the proper functioning of our organs and our immune system. How can we preserve and stimulate it? By setting the flow in motion, because, like the muscles or the skin, the endothelium requires mechanical stimulation to be activated and play its predominant role in the body.
