hydraSense® sources its seawater exclusively from the tides in the Bay of Saint-Malo in France. Among the most powerful tides in the world, the seawater’s composition is constantly renewed by the strong currents, oxygenating it and regenerating its mineral salt content.

Uniting all the benefits of this mineral-rich seawater with the latest scientific advances, we desalinate the seawater to an optimum level by electrodialysis. A study shows that this process preserves practically all naturally occurring trace elements and minerals. The result is a solution of exceptional quality.

In contrast, when other saline nasal solutions dilute their salt content to roughly 1/3 the salt content of the ocean, they dilute their valuable mineral salts and trace elements in the same proportion.

To make hydraSense®, the salt content of the Bay of Saint-Malo’s seawater is desalinated to one of two options: 0.9% or 2.2%.
