The Ordinary Marine Hyaluronics, available in a compact 30 ml / 1 oz bottle, delivers ultra-lightweight hydration with marine-derived water reservoirs that attract and hold water like hyaluronic acid, but with a feather-light texture that layers effortlessly under makeup.

Designed as a vegan, environmentally mindful alternative to traditional HA, this serum uses sustainable marine derivatives to flood skin with moisture.

Key ingredients include exopolysaccharides from skin-friendly marine bacteria, Hawaiian red algae, Antarctic glycoproteins, micro-filtered blue-green algae, and essential amino acids. The total concentration of active ingredients in this formula is 23%. Its ultra-light texture makes it ideal for layering with other serums and moisturizers. If you prefer a more viscous feel, explore Hyaluronic Acid 2% + B5.
