Sterimar Congestion Relief

Stérimar Congestion Relief (historically known as Stérimar Hypertonic) is an advanced, non-medicated nasal spray formulated to relieve severe nasal blockage and sinus congestion. When you experience a cold, flu, sinusitis, or allergies, the blood vessels lining your nose swell heavily, trapping fluid and causing a painful, stuffy feeling.

Unlike medicated nasal sprays that use chemical drugs to artificially squeeze blood vessels, Stérimar relies on a purely physical mechanism called osmosis. Sourced from pure sea water filtered from the Cancale Bay in France, this micro-fine spray clears fluid away naturally, washes out sticky mucus, and restores free breathing without a chemical burn or a bitter aftertaste.
