It naturally relieves nasal congestion (osmotic mechanism) and cleanses the nasal cavities by removing excess mucus and trapped impurities, such as pathogens, allergens, and pollutants. This helps maintain a healthy nose and prevent secondary ENT infections. It also moisturizes dry nasal mucosa. Regular spray, suitable for adults and children over 6 years old. Posology 1 to 3 sprays in each nostril, 2 to 3 times a day.
