Why you need The Ordinary Marine Hyaluronics:
The Ordinary Marine Hyaluronics is an ultra-lightweight hydration support with marine-derived vegan water reservoirs. 
Marine Hyaluronics brings together lightweight marine-derived water reservoirs that attract and hold water like hyaluronic acid (HA) but are lighter than HA in texture and feel. 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%.
The Ordinary Marine Hyaluronics has a slight odour due to the presence of marine extracts. This is completely safe and natural.
