The Ordinary Marine Hyaluronics is a lightweight marine-derived water that helps to lock moisture in your skin, much like a Hyaluronic Acid does. The difference? The consistency of the Marine Hyaluronics is thinner and lighter, more like water than a typical serum texture. This facial serum helps to attract and hold water in the skin, ensuring your complexion remains plump and hydrated throughout the day. This product is fast absorbing, suitable for all skin types and should be used before facial creams.

The formula contains exopolysaccharides from skin-friendly marine bacteria, Hawaiian red algae, Glycoproteins from Antarctic marine sources, micro-filtered blue-green algae and several health-supporting amino acids. All marine derivatives in Marine Hyaluronics are sourced sustainably. The total concentration of active ingredients in this formula is 23%.

This formula is exceptionally light in texture. If you prefer a thicker consistency, try the Hyaluronic Acid 2% + B5.

All of our products are filled/measured by weight/volume so the product is correctly filled to 30ml. The packaging does not accurately reflect the size of the fill. However, this is intentional as some air must be allowed at the top for the product to actually close.
