OSEA Hyaluronic Acid Sea Serum

OSEA Hyaluronic Acid Sea Serum

A burst of hydration for all skin types. This fast absorbing concentrated serum smooths the appearance of fine lines and provides visible lift. Our nourishing formula draws water-based moisture to the skin like a magnet. A synergy of three molecular weights of Hyaluronic Acid and three nutrient-rich seaweeds work together to restore and maintain optimal moisture levels, keeping your skin hydrated all day long.

How to Use

After cleansing, apply the serum over your skin. Allow it to absorb and then seal it in with your choice of OSEA moisturizer. Use it in the morning and at night for best results. For added hydration, dampen your skin with the Sea Mineral Mist before applying the serum.


  • Fragrance-free and oil-free

Featured Ingredients

  • Proprietary Trio of Seaweeds (Gigartina, Macrocystis, Undaria): Algae abundant in vitamins, minerals, antioxidants, and essential fatty acids. Hydrates, nourishes, and provides anti-aging benefits.
  • Hyaluronic Acid: Plant-derived polysaccharide that holds water and is also found naturally in the skin. This hydrophilic (water-loving) molecule delivers moisture without clogging pores and helps prevent water loss.
  • Sodium Hyaluronate: Ferment of Hyaluronic Acid. This water-soluble salt is a smaller molecular size than Hyaluronic Acid and helps restore the skin’s moisture barrier.
