I had almost resigned myself to really having just bad body odor. Even name brand antiperspirants, much less deodorants which don't even prevent sweating, I thought, did not work with me even if I'm careful to let them dry before putting on any clothes. I'd smell by midday.
Anyway, I stumbled upon this rather expensive deodorant, and decided to give it a shot. I was looking around for reviews and other stuff about this deodorant online and one of the stuff I found was this supposedly had an "adjustment period," wherein it would take a few applications/days before it'd actually start "working," i.e. make one not smell. However, I was pleasantly surprised that it actually worked the first day I applied it. It says, "up to 72 hrs," but today was the 4th day since my last application and I was running late so I forgot to reapply, but I did not end up smelling. Really worth the gamble, in my opinion.
