No fillers. As more & more natural products make their way into the market, it seems like there are more natural preservatives to learn the names of. Sometimes it can feel confusing even when reading the labels of natural products, so we will only ever use 100% natural ingredients and we never add cheap fillers. Our deodorants are effective because we only use pure, naturally powerful, (and antibacterial) ingredients. No fillers. That also means they last for ages! Win/win.
