This gel-serum with exceptional glide-on power instantly quenches even the thirstiest skin. Its fine texture also improves the texture of the skin. Highly enriched in PHA (Precursor of Hyaluronic Acid), this hydration-activating concentrate works throughout the night to encourage the resynthesis of hyaluronic acid, helping restore the foundations of the skin so they gradually distill water to the surface. With regular application, the skin regains optimum moisture levels and greater density. This exceptional serum delivers both immediate effectiveness and long-lasting anti-aging hydrating performance.
