For years, there have been claims that the aluminum-based antiperspirants cause cancer, especially breast cancer. However, research has found no clear link between aluminum in antiperspirants and cancer. According to Dr. Susan Massick, a dermatologist and associate professor at Ohio State Wexner Medical Center: “The claim that aluminum-containing antiperspirants cause cancer is a myth that has been debunked in the minds of doctors and scientists, and so it’s time to put lingering doubts for consumers to rest,” (Ohio State Health and Discovery).
Aluminum as a compound may harm your health, but what is used in antiperspirants are salt derivatives of aluminum. Just like sodium chloride, the table salt we all use for seasoning food. Sodium on its own is explosive when added to water, while chlorine gas is toxic. But when mixed in the right proportions, we get edible table salt.
The difference between deodorants and antiperspirants
Deodorants and antiperspirants are two different things, performing two distinct functions. In the U.S., for example, deodorants are considered cosmetics, while antiperspirants are classified as drugs and regulated by the Food and Drugs Administration (FDA).
Deodorants are designed to combat body odor without affecting perspiration, while antiperspirants contain aluminum compounds to reduce sweating. Which one to use will entirely depend on your own needs. Some people barely sweat, so a deodorant may be suitable for them. Others sweat a lot, so they might need an antiperspirant — or both — to reduce the sweating rate.
The truth about sweat and odor
When sweat leaves your body, it has no odor at all. It’s the interaction with bacteria on your skin that leads to the familiar unpleasant smell. Different people have different strains of bacteria on their skin; hence, everyone has a different body odor. Your left and right armpit might also smell different according to the type of bacteria that inhabit them.
Addressing the myths
Despite the popularity of claims linking aluminum-based antiperspirants to health issues like breast cancer, Alzheimer’s, and kidney diseases, extensive research has consistently shown no direct link. Studies in respected publications like Critical Reviews in Toxicology reinforce this, highlighting the lack of association between aluminum-based antiperspirants and breast cancer. It’s crucial to remember that cancer is a complex disease influenced by a multitude of factors, rather than a single substance.
Safety and usage of aluminum-based antiperspirants
When using antiperspirants, only a small amount of the product is applied to the skin, and the absorption of aluminum is minimal. Considering that you also encounter aluminum in your diet and environment, singling out antiperspirants as a health risk is unfounded.
That said, large amounts of aluminum in your body can cause kidney disease. However, according to the National Kidney Foundation, the amount absorbed through your skin from antiperspirants is too small to cause illnesses in a perfectly healthy person. But if you have any previous or current history of kidney disease, then you should avoid aluminum-based antiperspirants.
Alternatives to aluminum-based antiperspirants
As mentioned, aluminum-based antiperspirants should not worry you unless you are suffering from kidney disease. If you are experiencing hyperhidrosis (abnormally excessive sweating), you should talk to your healthcare provider to recommend a suitable course of treatment.
Aluminum-free options include botox injections, miraDry underarm treatment, and deodorants. But if you want to avoid chemical use for personal reasons, you can try DIY alternatives, such as baking soda deodorant, cornstarch deodorant, arrowroot powder, and organic aloe vera deodorant.
Takeaway
The narrative surrounding aluminum-based antiperspirants has been fraught with misinformation, largely propelled by social media. However, scientific research provides a clear picture: These products are safe for the vast majority of people. As with any personal care product, the choice between deodorant and antiperspirant should be guided by individual needs and preferences. If excessive sweating is a concern, professional medical advice can help in selecting the most appropriate treatment.
