We use multiple forms of Hyaluronic Acid (Low Molecular Weight, High Molecular Weight,?and Botanical Polysaccharide) to infuse the skin with concentrated moisture and plump up fine lines. Besides hydrating, this formula trains the skin to retain moisture better while strengthening the skin barrier with Niacinamide and Phospholipids. An optimal concentration of powerful antioxidants, 5% Resveratrol Ferment Extract and 2% Superoxide Dismutase offer a dramatic reduction in signs of fatigue, promote firming, and support healthy barrier function. Palmitoyl Tripeptide-38 promotes rejuvenation and improves skin elasticity. At the same time, Strawberry Fruit Extract prevents anti-hyaluronidase activity (a process where enzymes in the skin break down natural Hyaluronic Acid), thus helping to protect the moisturising capacity of the skin. This serum goes beyond simply moisturising the skin ? it infuses it with concentrated moisture and prevents the breakdown of natural Hyaluronic Acid. Over time, skin is trained to retain moisture better all day long. – Allies of Skin Multi Hyaluronic Antioxidant Hydration Serum, 1 fl oz
