The Active Sea Mineral Deodorant Stick works really well and has great duration of effect over a few days. The scent is also very very appealing and non-offensive to the senses. This must be due to its natural ingredients because with synthetic and artificial scents, I have allergic reactions in my airway and lungs, but not with this product, and Honestly Phresh's Unscented Prebiotic Deodorant that I’ve also used. For many years I was using straight baking soda due to chemical concerns with standard deodorant products, but that started causing irritation spots with burning itching and weeping. I had to use prescription cortisone to clear them and then they would reoccur every three to six months. So for a few years I was using nothing, but then we had a recommendation for Honestly Fresh, which I tried and now use with no issues at all. Interestingly, another unexpected result from using both Phresh products is that the irritations stopped reoccurring. I am not sure why, but something about the Phresh product ingredients is helping. This has been a huge relief because using the cortisone had its problems with causing systemic fatigue. I am not providing any medical advice here, but just speaking to my own experiences, I am pleasantly surprised and very happy that I gave Honestly Phresh a try; two products with the same results. We will be definitely be continued customers.
