Evin Isotonic/Hypertonic Nasal Spray is a seawater-based nasal cleanser available in a 50ml bottle. It is designed to help clear the nasal passages by using purified seawater, which is naturally rich in minerals and trace elements. The spray comes in two variations: isotonic and hypertonic.
The isotonic version has a salt concentration similar to that of the body’s cells, making it gentle enough for daily use, especially for moisturizing and cleaning the nose without causing irritation. It helps remove dust, allergens, and pollutants, making it suitable for people suffering from mild nasal congestion, allergies, or dryness.
The hypertonic version has a higher salt concentration than body fluids, which helps draw out excess fluid from swollen nasal tissues through osmosis. This makes it particularly effective for reducing nasal swelling and congestion caused by colds, sinusitis, or allergies.
Both versions support natural breathing by helping to flush out mucus and contaminants, promoting nasal hygiene and comfort. The product is typically free from preservatives and drugs, making it safe for long-term use and suitable for both adults and children, depending on the specific formulation.
