A nasal spray made from hypertonic seawater, which facilitates the washing of the nose. Indicated during colds, allergies or flu, it favours better breathing, since it clears the nostrils of mucus. Its use also moisturises the nasal cavity that is irritated or dry and prevents the possible spread of pathogens. It has a practical diffuser applicator that launches a multidirectional jet for easy access to all corners.
