AllerRin Biosterine® is a rhinological solution based on plant extracts to be sprayed into the nasal passages. The hyaluronic acid contained in the formulation creates a protective film-forming effect, which protects the nasal mucosa from contact with environmental allergens. In addition, the presence of Biosterine® (a phytocompound consisting of Holy Basil and Sage, titration at 40% in Rosmarinic Acid) and extracts of Perilla, Caper, Water Lily and Red Tea, performs a decongestant, emollient and soothing action, relieving discomfort due to irritation and inflammation, contributing to the normalisation of the physiological functions of the nasal mucosa, thanks also to the isotonicity of the formulation. Finally, the addition of plant glycerine helps restore the correct level of hydration of the mucosa, limiting hyperreactivity.

The application can be repeated 4-5 times during the day. If a slight burning sensation is perceived, due to the high concentration of the active ingredients in the product, it is possible to spray once, wait a few minutes and then spray a second time.
