Give it a few days!
I made the transition after going back and forth between commercial aluminium-filled antiperspirant/deodorants and trying various natural deodorants like the crystal one, and this is by far the best one I have tried. So good, in fact, I threw my aluminium one on the bin! Now, that being said ... you must give your armpits a few days to clear out. A kaolin clay mask to draw out impurities works fabulously and speeds the process, but otherwise expect to have a bit of light BO for the first few days. After that, though, it does a splendid job of keeping you fresh smelling. I lift weights and put it to the test at the gym, and I must say I smelled rather nice after my lifting session. The texture of the deodorant paste itself is quite soft and easy to apply. The scent is VERY light and hardly noticeable. I applied it to my freshly shaven armpits and had no irritation whatsoever. I will definitely be buying more!
