How does it work?Fess helps relieve nasal and sinus congestion due to allergies, hayfever, colds and flu. The non-medicated saline solution keeps your nasal passages moist and washes away allergens such as dust and pollen. Use with medicated nasal sprays. Use Fess before your medicated nasal spray to help clear excess mucus and aid penetration of the medicine. Alkaline buffered. Maintaining Nasal Health. Your nose has a self-clearing system that can remove allergens, dust, pollen, and other pollutants from your nasal passage. When there is excess mucus and congestion this self-clearing system may not function at its best. Using Fess daily can help restore and optimise this self-clearing system.
