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

An antiperspirant's job is to reduce sweat. It does this with aluminum salts, which dissolve in your sweat and form temporary plugs in your sweat ducts, so less sweat reaches the skin's surface. Because odor needs moisture for bacteria to feed on, reducing sweat also reduces odor as a side effect. The defining feature: it's actively interfering with your sweat glands. If you see "antiperspirant" on a label, it contains aluminum — that's a regulated, required active for the claim.

Deodorant: handles odor

A deodorant doesn't touch your sweat volume. You'll sweat normally. Its job is purely odor — and there are two ways products go about it:

• Masking: covering odor with fragrance. Temporary; fades.
• Eliminating at the source: acting on the bacterial process that creates odor, so the smell is dealt with rather than covered.

A deodorant won't keep you dry. It's not trying to. It's trying to keep you from smelling.

Which one do you want?

• You mainly want to be dry / stop sweat → that's an antiperspirant, and it means aluminum.
• You're fine sweating but don't want to smell → that's a deodorant.
• You want odor control without blocking sweat or using aluminum → that's specifically a deodorant that eliminates odor at the source, not one that masks.

That last category is exactly where Zaffré sits. BioShield™ is a deodorant system — it doesn't block sweat and it doesn't mask. It eliminates odor at the source using zinc-based chemistry, so your body sweats normally and the odor still gets handled. We don't mask. We don't block.

If you've been frustrated that a "natural deodorant" didn't keep you dry, this is usually the missing piece: no deodorant keeps you dry, by definition. The question is whether it controls odor — and whether it does that by covering it or by eliminating it. MAX and SENSITIVE do the latter.
