Exceptional-quality seawater, sourced in France

What sets Stérimar™ sprays apart is their unique formulation, made from seawater sourced from a protected environment: the Bay of Cancale, off the coast of Mont-Saint-Michel. This area is renowned for its rich ecosystem and its tides, which are among the strongest in Europe.

The water there is constantly renewed, ensuring optimal purity and a high concentration of trace elements and minerals. Among these essential elements are:

  • Sodium chloride (NaCl): maintainsthe fluid balance of the nasal mucous membranes.
  • Copper and manganese: possess antiseptic and anti-inflammatory properties.
  • Zinc and sulfur: strengthen the immune barrier and promote cell regeneration.
  • Magnesium: has soothing and moisturizing effects on irritated tissues.

Thanks to its high bioavailability, the seawater used by Stérimar™ is perfectly compatible with the body’s cells, ensuring a gentle, effective, and natural action.

Advanced technology for optimal delivery

The effectiveness of Stérimar™ sprays also relies on their patented technology, designed to ensure uniform microdiffusion and safe use.

Each spray is equipped with:

  • A sterile pouch valve: preserving the integrity of the solution without the need for preservatives.
  • An ergonomic tip: facilitating administration and minimizing the risk of irritation.
  • A precise spray nozzle: ensuring optimal distribution of the solution within the nasal passages.

Clinical trials have proven the effectiveness of Stérimar™ formulas, particularly in reducing the symptoms of colds, allergies, and sinusitis. These solutions are suitable for all ages, including infants, thanks to controlled pressures and specialized tips.
