Gilbert Marimer Hypertonic Saline Nasal Spray is a hypertonical sterile and micro-diffused sea water solution. Naturally rich in mineral salts and marine trace elements. The nasal spray Marimer Hypertonic is recommended for children and adults for the cleansing and decongestioning of the nasal airways, in particular, in case of blocked nose, sinusitis and cold. The micro-diffusion system of Marimer Hypertonic and the mechanical effect of the hypertonic water facilitate the drainage of the nasal airways. The cleansing of the nose protects the mucous membrane from the external attacks and also helps the nose to assure its breathing function.
