Is aluminium chloride in antiperspirants dangerous or even carcinogenic?
Despite a number of studies, the German Federal Institute for Risk Assessment (Deutsches Bundesinstitut für Risikobewertung) could not establish any connection between the use of aluminium- containing antiperspirants and breast cancer.
As long as the aluminium chloride does not enter the bloodstream through micro-injuries (e. g. from the previous shave), it cannot cause any damage - according to the Federal Institute for Risk Assessment.
Tip: If you want to be sure, wait 24 - 48 hours between shaving and application.
Waxing does not cause this problem.
