From a women who suffered bad from 17 years old with deodorant allergies. To the extent of red weeping sore under arms. It was very embarrassing, but back then in 1998 I didn’t have many options. When more natural deodorants became available over the years I’ve tried them all. Only to have a reaction 2-3 months down the track. I did react to your original no pong. But as soon as the bicarbonate free one came out I ordered it and I’ve been very happy since! So thank you for creating such a product! I’m now 39 and no more allergic reactions to deodorant! *touch wood*
