This filler is a non-invasive alternative to surgery and wrinkle fillers such as Restylane. The Hyaluronic Acid in this filler penetrates into the varying depth of the skin folds and trap water in the fine lines and wrinkles. Clinical test results show a decrease of 7.5%, in forehead expression wrinkles after one hour and 12% after 6 hours. The Filling Spheres are composed of a mixture of high and low molecular weight hyaluronic acids, perfectly accepted by skin tissue. When they are applied, they easily lodge in skin tissue depressions (wrinkles) where they progressively but rapidly rehydrate by taking up water that evaporates from the skin. This physical action leads to a volume change of Hyaluronic Filling Spheres in the epidermis that almost immediately smoothes deep wrinkles such as expression wrinkles, at the same time increasing the long-term hydration of the upper layers of the epidermis.
