Experience unrivalled hydration with Institut Esthederm's Intensive Hyaluronic Serum, a highly concentrated serum infused with three forms of Hyaluronic Acid (240g) and Cellular Water (a replica of the water found in our skin cells) to help treat acute dehydration. Working to restore the skin's hydrolipidic film and regain levels of optimal moisture on all layers, the serum provides instant and long-lasting relief to parched skin; its lightweight texture penetrates effortlessly to help restore natural water levels and intensely rehydrate. Its trio of Hyaluronic Acids not only help to attract and retain water, but also plump out the appearance of fine lines and wrinkles for softer, smoother, younger-looking skin. Skin looks and feels restored and comfortable. Suitable for severely dehydrated skin. All Institut Esthederm products are formulated with Cellular Water.
