Sterimar Nasal Hygiene Spray 100ml is made from filtered sea water and helps clear away mucus from your little one's nose to ease their breathing. And because it is 100%% natural and contains no preservatives, it is suitable for use in babies aged 0-3. Can also be used by adults. , , Each dose of Sterimar delivered is aseptic. The anti-reflux valve prevents air from entering the can. The solution remains perfectly aseptic after each use. Sterimar can thus be used safely again and again until it reaches its expiry date, even after multiple uses. The Sterimar exclusive nozzle is anatomically formed and self-blocking: it can be used as safely on the tiny nostrils of a baby as on those of an adult. Its graduated diameter adapts to all nostril sizes and prevents any risk of accident when inserting the nozzle into a baby's nostril.
