Half the people who say natural deodorant “doesn't work” are actually annoyed it didn't keep them dry. It was never going to. Deodorant vs antiperspirant is the difference between two machines built for two different jobs, and most of this category's bad reputation lives in that one mix-up.
Antiperspirant blocks sweat (with aluminum). Deodorant handles odor and lets you sweat normally. If you were frustrated a “deodorant” didn't keep you dry, that's the mix-up, no deodorant does.
Reduces sweat using aluminum salts that plug your sweat ducts, so less sweat reaches the surface. It's actively interfering with your glands. If a label says “antiperspirant,” it contains aluminum, that's a regulated, required active.
Doesn't touch sweat volume, you sweat normally. Its job is purely odor, either by masking it with fragrance (temporary) or by removing the molecules that carry it (dealt with, not covered).
Which one do you want?
That last category is exactly where Zaffré sits. BioShield™ is a deodorant system, it doesn't block sweat and it doesn't mask. A zinc mineral captures the odor molecules directly, so your body sweats normally and the smell doesn't arrive. We don't mask. We don't block.
