Isotonic solution with sea salt, which is formulated for people with disorders of the normal physiological function of the nasal mucosa, in order to maintain the daily hygiene of the nasal cavity. The solution restores the nose to its natural moisture with self-cleaning ability and normal mucus production, which protects it from drying out and from mechanical stimuli (tobacco, dust, etc.). Regular rinsing of the nasal cavity several times a day reduces the risk of upper respiratory tract infection. How to use: Apply 1 spray to each nostril several times a day.
