Our skin is our largest organ and what we put on it gets directly absorbed through our open pores. Personal care products and fragrances are notorious for containing toxic ingredients that we don't want in our body.
I always struggled to find a natural, clean, aluminum free deodorant that actually worked until I found this brand, Schmidt's natural deodorant. They have many scented and unscented varieties. Try them for yourself to keep you and your pores clean and fresh!
