This stuff works! I started using this a month ago and have decided to make this my permanent deodorant. I used to use aluminum deodorant and decided to stop because of all the cysts it was causing in my armpit area. This was the first aluminum-free deodorant I tried and I'm sticking with it. Stank stop is an accurate name because when I was using aluminum deodorant if I didn't put it on right out the shower, my pits would immediately be funky. I don't have that problem anymore. I do vigorous sweat inducing workouts twice a day and this stuff just keeps going. The pleasant lavender/sage smell does dissipate over time but I never smell stink or funk. Also, dont let the little jar fool you, a little goes a loooong way. I'm 31+ days into the jar I bought and I still have over half left.Some tips:1. If you feel weird about getting this on your fingers, Little Seed Farm sells these cute little bamboo deodorant applicators right here on Amazon. They come in a two pack. You have to use the small end, not the big end like intended but they keep your fingers out the jar and really help spread the deodorant and absorb it into your pits.2. Do not switch to natural deodorant cold turkey. If you are planning to stop using aluminum deodorant the second this arrives at your door you NEED to prep your pits or you will stink and stink bad, and then you'll probably be on here writing a review about how this deodorant doesn't work. That aluminum deodorant has been plugging your pores for however long you've been using it. So your pores haven't been able to sweat or release all that bacteria inside them. If you think you're going to stop using aluminum deodorant and smell like a bed of roses let me tell you, all that ick is going to start to leech out and your going to smell horrible. So you need to detox to get all that icky stuff out while you transition to the natural deodorant. Get some Aztec Secret Indian Bentonite Clay, some apple cider vingar, and some Thayers Rose Petal Witch Hazel. Before you shower, whip up the clay mask and put it on your pits and let it sit (follow instructions on jar) so it can draw all that crap out your pores. I don't recommend rinsing the mask off in the sink you don't want clay in your pipes. Either use a wet towel or wipes to clean off the bulk of the mask and then shower like usual. When you get out put the witch hazel on your pits. The rose water cleans the pores and the witch hazel is antibacterial and will close the pores, not clog, close so that when you sweat they will open again like they're supposed to. Then put on your natural deodorant. Do the masks for a week. Personally I still use the witch hazel on my pits before deodorant application because I enjoy the extra cleansing properties and I spent money on this big bottle of Thayers so I'm getting my moneys worth. Up to you. But I hope these tips help.
