Ozone is simply OXYGEN with an extra oxygen molecule, turning it into a more available form for your cells to accept. You, along with every single cell that your body is made up of, need oxygen to survive. Ozone in the Rejuvenation Capsule has the advantage that it is easily absorbed through the skin which hands it off to the bloodstream, which delivers the oxygen molecules to the rest of your vital organs without you having to breathe it in or puncture your skin. (Some other methods of ozone intake, including directly inhaling or injecting into your veins, are not recommended.) Your therapeutic and relaxing experience in the Rejuvenation Capsule will include ozone being absorbed directly through your skin and into your cells and whole body system, thus improving overall bodily function.
