I normally only use stick deodorant (the dove cucumber one is my regular jam) because I like the application, it doesn't sting etc but giving this a go it wasn't as scary an experience as I remember - it doesn't blast you with a strong stinging spray of pain and feels akin to putting on dry shampoo.
The smell is really pleasant but hard to explain - a sort of powdery soft floral scent. Not invasive at all and I'm usually sensitive to fragrance.
As for performance, I don't have a big problem with sweat usually so don't opt for anything too heavy duty in that regard, I do however experience anxiety attacks from time to time so stress sweat is a concern for me. I had a few triggers and small episodes while trialling (mostly induced to see how we went) and the performance was great - there wasn't a noticeable change in sweat or odour - sounds icky but I'm not afraid to admit it's a concern. When you're freaking out the last thing you want to worry about is being sweaty and smelly.
Longevity wise on a regular day I only had to apply once in the morning and the performance seemed to be pretty solid through out the entirety of the day. If sweat is a particular concern of yours you may need to top up through out the day but I can't say for certain.
My sensitive skin didn't react adversely at all, no stingy or redness or itchiness which is a big relief. It fires up at most things so I would definitely recommend this to girls with sensitive skin!
I took one "kiss" off of "Would you recommend it to a friend" just because if you do sweat a lot or stress sweat isn't a big concern for you there could be better deodorants out there for you but in general I would be happy to recommend it.
Great product , only had to use in the morning and found it did last all day..will certainly be buying it again , sample pack is a great size for my handbag, maybe Nivea should bring one out in that size ...
