Hyaluronic Filling Spheres™ provide an exclusive technology based on the use of hygroscopic material to make a sphere. These spheres are dehydrated at first, and fill up with water within the skin. This hydration process causes a change in volume proportional to the sphere's moisture-retaining capacity. This physical change in volume allows for rapid filling results which produce a noticeable smoothing of deep wrinkles which with continued use are just as effective as the components used in injections.
