From http://www.cancer.gov/cancertopics/causes-prevention/risk/myths/antiperspirants-fact-sheet :
"Some research suggests that aluminum-based compounds, which are applied frequently and left on the skin near the breast, may be absorbed by the skin and cause estrogen
-like (hormonal) effects. Because estrogen has the ability to promote the growth of breast cancer cells, some scientists have suggested that the aluminum-based compounds in antiperspirants may contribute to the development of breast cancer"
Considering this, I'm happy to avoid deodorants containing aluminum.
But is aluminum to be avoided in all skincare and cosmetics products? Any difference between aluminum applied on armpits, face or other parts of the body?
