I've just started using the Rexona Clinical Protection... I'm about at my wits' end. So far, though, it appears to be working, if this keeps up it'll officially be the answer to my prayers!! I sweat like a bloke, even in the middle of winter (and I live in Central Queensland so it's around 30C for 48 weeks of the year!). It's hideous. Not to mention really unladylike! Other 'strong' antiperspirants work for a couple of hours, if that, then I just big wet patches under my arms as well as the stench of stale fragrance mixed with sweat. Ick.
I know it's probably full of chemicals and what not, but no way on Earth am I able to get away with crystal/natural deodorants - if this keeps working I'll keep forking out the $13 a pop for it, it's well worth it to finally be dry!
