So if antiperspirant prohibits a natural process — and turns your T-shirt a darker shade of grey in the process — could it actually be dangerous?
Sweat Baby, Sweat — Why It Matters
We all use some sort of deodorant every day (or at least, we hope everyone does to avoid a very uncomfortable day at the office). And it’s pretty standard for those anti-stink sticks to include an antiperspirant to keep things dry and smell-free. While some turn to natural remedies for underarm hygiene, it’s important to know that even natural deodorants and antiperspirants contain some of the hard to pronounce stuff. So what does it all mean? Here’s the key stuff to look for:
Aluminum: Not the foil kind. It’s usually the first ingredient on the tube in antiperspirants. Aluminum can enter the body not only through cosmetic products, but also from what we eat. Over the counter antiperspirants contain between 10 and 25 percent of their “active ingredient,” which is usually an aluminum-based compound.
Penetration Enhancers (aka accelerants): These guys penetrate skin to reversibly decrease barrier resistance. (That means they alter the top layer of our skin.) Propylene glycol is a common one to look for. Penetration enhancers don’t pose much harm themselves, but they allow for other chemicals to be more easily absorbed
Fragrance: The term fragrance is pretty vague (eau de what?!?!). Many deodorants, antiperspirant or not, contain unspecified ingredients to make skin smell nice (or attempt to, anyway). In one large study on cosmetic allergies, deodorant was the leading cause of dermatitis (in men), an allergy-related condition when skin becomes red, sore, or inflamed
Triclosan: This stuff kills bacteria housed in those pits (bacteria likes dark, moist environments). Fun fact: It’s not the sweat itself that smells, it’s the bacteria. Triclosan shows up in a lot of personal care products because it’s considered pretty safe. Allergies and sensitivities to the chemical aren’t common, but several cases of skin irritation have been reported
So if we all use it, it can’t be thaaaat bad, right?
Don’t Sweat the Small Stuff — The Answer/Debate
As the main ingredient in antiperspirants, aluminum stands out as the most debated as far as risk factors go. The chemical element is the most widely distributed metal in the environment. There are plenty of studies explaining what happens when we ingest it, but there’s less research about what it does when we put it on our bodies
One study showed that antiperspirants with aluminum are safe when applied to healthy skin for a limited amount of time
Since aluminum is in our food, water, some medications, and the air we breathe, it may not be time to chuck that BO-stick out the window and get all hippy-dippy on us. The FDA gives us the go-ahead to use antiperspirants and considers them safe and effective. But they also require that all antiperspirant products containing aluminum include a warning to advise people with kidney disease to check with a doctor before using (because kidneys help remove excess stores of aluminum from the body).
Because it’s foreign to our bodies, aluminum may pose a threat over time. But even though there are theoretical concerns about our de-stink sticks, there really isn’t any data that confirms harm. If you do chose to nix the sweat blockers, many popular brands carry deodorants without antiperspirants — just check the label. If crazy ingredient lists on your deodorant tube are concerning, try one sans-antiperspirant or concoct DIY deod with baking soda.
