For the past year or so I've been using the crystal deodorant stick because I wanted to stop using aluminum-based deodorant. And when I tried to make the switch years ago it wouldn't work for me - after researching it I came to find out that you need a good 3 weeks or so to detox enough where B.O. is no longer a problem. Then COVID! When better to smell like B.O. for 3 weeks than during a mandatory stay at home order?! The crystal is fine for its purpose - i.e. you'll still sweat - but you won't stink (the compound prevents the B.O. causing bacteria from growing). However, it wasn't enough for me to just not stink. I actually did miss the smell of a good deodorant, which is why I finally opted to try this product from FACTO. I got the scotch pine and coriander fragrance and it's awesome! Again - you'll still sweat, but you won't stink and you'll actually smell good! Sweating is a natural process and my guess is that you don't want to mess with that else you're probably looking at other problems, longer-term. I would recommend this product and look forward to trying the other fragrances.
