A lot of doctors and cancer experts say they find no measurable adverse effect or causal link between aluminum (the active ingredient in most antiperspirants), parabens (a common bonding agent in deodorants and many other products) and abnormal breast tissue. However, new research out of Great Britain cites recent studies which show potential significant links.
British researchers have revisited the question of aluminum in breast tissue. The researchers acknowledge that humans are exposed to metals and parabens in large quantities from a number of sources, but cite antiperspirants and deodorants as key players in those exposures. Why? Because they’re finding more of them, and the compounds they can copy, in human breast tissue with no explanation for why it’s in larger quantities there than in other areas of the body.
In brief, they found more aluminum in the breast cells of humans than that in the blood, which indicates that aluminum is either collecting from the bloodstream in the breast tissue, or that aluminum from another source is depositing it there. Aluminum can negatively impact the epithelial breast cells and the overall health of the breast tissue which may lead to cancer. Parabens, which are the other concern in underarm products, can mimic oestrogen in the body. Oestrogen has been linked to breast cancer.
Other researchers and analysts for the deodorant and antiperspirant industry state that the amount of aluminum absorbed through the skin from underarm products is so small (0.01%) that it should not be a concern.
Whether over-exposure to these metals and compounds can be blamed on our underarm hygiene products or not, it seems that the new findings call industry claims into question. With clarsskin cleanser, you know you’re washing away those harmful compounds in the most effective way possible—the evidence is clear when you shave—clarsskin washes away antiperspirant and deodorant residue.
