Is Aluminum Antiperspirant Salts safe during pregnancy?
Everyday antiperspirant ingredient. No pregnancy-specific concerns found; skin absorption appears low.
What the sources say
NCI says there is no conclusive evidence linking antiperspirants to breast cancer. A 2021 review notes skin absorption of aluminum is not well understood and harm has not been proven. No sources raise pregnancy- or breastfeeding-specific concerns, but no pregnancy studies exist, so this is rated limited. Limit: normal underarm use as directed on intact skin. Aluminum-free deodorant is an option if you prefer.
