- Deodorant ≠ antiperspirant. Deodorants address odor; antiperspirants block sweat with aluminum compounds. They're not interchangeable, and the choice depends on what you're actually trying to fix.
- The aluminum–cancer link isn't supported. Major health authorities — including the FDA and the National Cancer Institute — find no scientific evidence linking aluminum in antiperspirants to breast cancer.
- Baking soda irritates skin. It's the most common cause of underarm irritation in "natural" deodorants. If you've reacted to one, this is the first ingredient to suspect.
