it doesn't it is instant relief

First time; so helpful and refreshing

good, been buying it for years now, work great 💯

Great product all year long especially in cooler weather when the heat dries the air out!

Had surgery in my nose and u used this

This is a small can and it barely puts any saline out. Very hard to use and not very effective

This has helped my allergies so much. I can breath easier

Reasonably priced, especially if you need this regularly. This product was suggested by my ENT.

I use as a nasal moisturizer, especially with dry weather and pollen.

I have using this for a while now and I really like it!
