Neauvia Organic Stimulate Man is the first filler capable to fight the passage of time in two ways. The high concentration of hyaluronic acid (28 mg / ml) and high viscosity of the hydrogel allows for longer maintenance of the effect fill tissue defects. The product also contains 1% calcium hydroxyapatite, which greatly stimulates fibroblasts subsidizing the production of collagen. Stimulate Man is formed with hyaluronic acid obtained from Bacillus subtilis. For cross-linking , they are using the PEG polymer, that allows to obtain the network made in IPN technology. Calcium hydroxyapatite fillers used in Neauvia are in the form of small particles (size 8 to 12 microns), cross-linked and evenly distributed within the hydrogel. This ensures stability of the molecules that are unable to migrate.
