Hypertonic Seawater Nasal Spray is an effective aid for daily respiratory hygiene. Its formula, based on pure seawater from the Bay of Cancale (Brittany), renowned for the quality and purity of its waters, helps to cleanse, hydrate, and decongest the nasal passages. Thanks to its osmotic effect, it eliminates excess mucus, reduces swelling of the nasal mucosa, and facilitates free and natural breathing. Suitable for children from 6 years of age and adults, it is indicated for colds, rhinitis, sinusitis, congestion, nasal dryness, or as a support for ENT and pediatric treatments. Propellant-free and with a convenient medium spray application, it provides comfort and safety for the whole family.
