There have been claims that regular deodorants and antiperspirants can disrupt or kill off the “good” bacteria living in your armpits, leading to skin irritation, redness, bumps and overall poor skin health. There isn’t enough evidence to show that they are. “This is why we offer natural deodorants without aluminum that provide odor protection, as well as antiperspirants that do contain aluminum for wetness protection.” Are natural deodorants good for your microbiome? “We believe it’s important for people to have choices to find the everyday products that are right for them,” said Justin Boudrow, a spokesman for Tom’s of Maine, which makes a variety of natural personal care products including toothpastes, mouthwashes, soaps and underarm products.
She did note that the link between aluminum and Alzheimer’s is challenging to study because aluminum is the third most common element in the Earth’s crust, which means that everyone is exposed to it in small quantities. “The whole topic has kind of been abandoned.” “The evidence is of poor quality, generally speaking,” said Amy Borenstein, a professor of epidemiology at the University of California, San Diego, who studies the causes of Alzheimer’s disease. But scientists now disregard the idea that aluminum can cause Alzheimer’s. This suggested that the metal - perhaps not only from antiperspirants, but also from other personal care and household products like pots and pans - could be a potential risk factor for this degenerative disease. There’s also been concern derived from decades-old research that found that Alzheimer’s patients’ brains had high levels of aluminum. Burstein added, only a minuscule fraction of aluminum can be absorbed through the skin, so your exposure to it from an antiperspirant is trivial. “The well-done human studies have really never suggested this,” he said, and the studies that have were often performed on animals or cells (like breast cancer cells in a petri dish) and used “unbelievably toxic levels” of the ingredients they were testing.Īnyway, Dr. Burstein said, the evidence just isn’t there to support this idea. The same goes for another cancer-related rumor, which is that the aluminum from antiperspirants could be absorbed into the skin and increase breast cancer risk by altering breast cell estrogen receptors.

“To date, there’s absolutely no evidence that breast cancer is caused by exposure to anything in antiperspirants or deodorants, full stop,” said Dr. This, say experts - including those from the American Cancer Society - is false. The letter also claimed that razor nicks from shaving could further increase breast cancer risk by allowing chemicals from antiperspirants to enter the body. It said that antiperspirants, which minimize perspiration by blocking sweat ducts, prevent the armpit area from “purging toxins,” which could build up in “the lymph nodes below the arms” and cause cell mutations and ultimately breast cancer. One of the biggest and most alarming false claims made about conventional antiperspirants is that they cause breast cancer - a rumor that began with an email chain letter from the 1990s.
In the end, the experts said, the way a deodorant makes you feel (and smell) should guide your decision to use it. In fact, they said, they’re perfectly safe.Īnd while natural deodorants might contain seemingly healthier ingredients than your conventional drugstore antiperspirant, they can still have substances that might irritate your skin. Many natural deodorant companies have seized on these perceptions, implying in their marketing that the ingredients in conventional deodorants are the “ stuff you don’t want,” and that what you do want is their “natural” product that is made from “plant- and mineral-based odor fighters” and “ clean ingredients.”īut experts, including an oncologist, an epidemiologist, a skin microbiome expert and several dermatologists, said that there is no definitive evidence that regular deodorants or antiperspirants are worse for your health than natural deodorants. Others assert that certain ingredients in traditional deodorants and antiperspirants are “toxic,” or that they can kill off the “good” bacteria in your armpits. Some claim that the aluminum in most conventional antiperspirants can lead to Alzheimer’s disease or cancer. Google “natural deodorant” and you’ll find countless articles detailing all the reasons you should buy them.
