Secret vs Lume: Antiperspirant or Aluminum-Free Deodorant?
This is a genuine functional difference, not just an ingredient swap: Secret is an antiperspirant, which physically blocks sweat glands. Lume is a deodorant, which neutralizes odor but doesn't stop sweating. That distinction matters more than the aluminum question for some people.
Quick answer: Secret is an antiperspirant containing aluminum zirconium pentachlorohydrex gly, which physically blocks sweat. Lume is an aluminum-free deodorant that neutralizes odor without stopping sweat, and is marketed for whole-body use rather than just underarms.
Winner: Lume Whole Body Deodorant
Lume wins on ingredient simplicity and skips aluminum entirely, and it markets for whole-body use, not just underarms. But if you specifically want to stop sweating rather than just control odor, that's a real functional difference an aluminum-free deodorant can't replicate — Secret's antiperspirant mechanism is doing a genuinely different job.

Frequently Asked Questions
Is it bad to switch from antiperspirant to deodorant?
No, but expect a real difference — without aluminum you will sweat normally, and the product's job shifts to controlling odor rather than stopping wetness.
Why does Lume market itself for whole-body use?
Lume's formula is designed to be gentle enough for use beyond the underarms, which is a specific positioning choice most conventional antiperspirants don't make.
