Any advice? I've been using it for three weeks sticking rigidly to the manufacturers guidelines. I am not expecting not to sweat. But I still smell. If I apply it every single day I don't smell but then again if I use any old deodorant then I can last a day without smelling - the whole point was to go for longer as per their marketing. I was using a natural one before so I don't think I need a purging period but anyway, three weeks seems sufficient. I'm not even a very sweaty person! Any ideas?!
