Very expensive but the best normal serum in my opinion, it comes very close to Sudafed Natural Relief Blocked Nose Spray (which unfortunately is not available in the Greek market). It cleans the nasal cavity very effectively, and it is the only one that contains sodium bicarbonate (that is, baking soda) in its composition, which I believe makes all the difference.

Having tried numerous salt toners to soothe my irritated and dry nostrils (due to a septoplasty surgery), I have concluded that the best hydration and relief, without leaving a feeling of "heaviness" or congestion, is provided by this product that DOES NOT contain sea water but rather a physiological serum. I will continue to use it (3-4 times a day), I just wish it had a nozzle that sprays the liquid almost like a powder, but again, I have no complaints!
