Nivea's anti-perspirant stress protect gives you 48 hour protection. Why they went for 48 hour protection, I don't know. If you have a shower a day (or more), then it's probably a bit over the top for you.
But how will you know when you should use it? Mostly you don't know that you are going to be stressed until you are, if you know what I mean. So, looking at this product as a kind of super everyday anti-perspirant, I have to say it keeps you absolutely and totally dry through the ups and downs of a normal day.
As a spray-on, it went on cold (as most spray-ons do) and dried much faster than my usual roll-on. No significant perfume.
If you like spray-on anti-perspirants, then this is a good one.
I have trialled this product for the last week & am amazed by how good this is - so much so, I purchased the full sized product today! This is the first aerosol I have tried that actually works, & leaves you completely dry :-)
