What's the mineral in "the crystal?" It's almost certainly an aluminum salt, but I can't find the active ingredient? The FAQ says "Do Crystal deodorants contain aluminum chlorohydrate or aluminum zirconium? No." That's a bit suspicious, as I think people would really want to know "does it contain aluminum?" and the answer is likely "yes."

BTW, you wrote "Your sweat lessens" with this product, but it does not. The FAQ stresses that it does not reduce sweat. "Crystal is not an antiperspirant. It is a deodorant ... Deodorants are generally considered cosmetic product because they simply control odor."



> I think people would really want to know "does it contain aluminum?" and the answer is likely "yes."

The answer is absolutely yes. They admit that it contains an alum, but don't specify which one. The "it's all natural because it's a salt" angle is BS, because aluminum chlorohydrate is also a salt.

Though it's probably just 1 in a mixture of many salts.

Even if regular deodorant has this listed as an ingredient, it's quantity is questionable, and it's mixed in with other substances that prevent the alum from making full contact on the surface of the skin.

> Your sweat lessens" with this product, but it does not. The FAQ stresses that it does not reduce sweat.

It does a bit. But not to a significant effect. It's probably a secondary effect (clean pores, less sweat ... something like that).
