Ingredient & formula breakdown
Water (Aqua):
Pharmaceutical-grade purified water forms the base of the solution. It is carefully processed to remove impurities, ensuring the formula is clean and safe for external and nasal use.
Sodium Chloride (0.9% NaCl):
At 0.9%, it matches the salt level in your body's fluids, making it isotonic — balanced so it won't draw moisture to or from cells. Gentle, non-irritating, and suitable for regular use.
Why the balance matters:
Too much salt (hypertonic) draws moisture into the nasal lining and can feel intense. Too little (hypotonic) can cause cells to swell. Isotonic sits in the middle — moisturising the nasal passages without disruption, making 0.9% the go-to concentration for gentle daily care.
“I wanted something simple and gentle to use daily, and this saline has been perfect. The single-use ampoules are so convenient, and it feels reassuring knowing it's preservative-free.”
