A product created specifically to prolong the results of hyaluronic acid filler injections. The formula contains cross-linked hyaluronic acid, similar to the one injected by doctors to recreate skin volumes and fill wrinkles. The formulation is a light and silky touch serum with a long lasting after feel. It also incorporates soft-focus technology to reduce the appearance of wrinkles and enlighten the skin tone. The scent is fresh and energizing, composed of a mixture of citrus fruits. The cross-linked hyaluronic acid is a polymer derived from natural hyaluronic acid (HA) similar as used in dermal fillers. The viscosity of reticulated hyaluronic acid solution is 2-3 times that of HA solution at the same concentration, which indicates that it can bind more water molecules because of its cross-linked structure. It behaves like a “micro reservoir” delivering continuously water to the skin. It can form a 3D “breathable” layer on the surface of the skin that improves the skin barrier function, fill wrinkles, reduces the water evaporation and prevents the skin damage caused by external aggressions like UV ray, pollution, etc.
