You shouldn't use any anti-perspirant with alluminum in it. Alluminum builds up in your system, and stays there your whole life, increasing your risk for alzheimers. Don't give me any bs about how you can't absorb it through your skin, because you can. if you don't shave your armpits then try using a natural crystal deodernt if you need an anti-pierspirant. It's colorless, odorless, and if used properly lasts 24 hours and the stick lasts up to a year.
