The adjustment period that accompanies making the switch to an aluminum-free deodorant has previously scared me off. Similar options left my armpits unbearably itchy; I was sweating more than ever, and my skin felt irritated. But when I started using the Kopari deodorant, I was shocked to find how little of that I experienced. To buy: $14; koparibeauty.com. Kopari’s natural deodorant is an entirely plant-based formula that includes coconut oil to hydrate the skin, as well as sage oil, which helps soothe potential irritation, according to the brand. It’s vegan, cruelty-free, and available in multiple skin-friendly scents as well as a fragrance-free option. The deodorant is packaged inside a plastic stick with a roller at the bottom that allows you to easily dispense your desired amount of product. Though I quickly fell in love with this deodorant, the change didn’t come without a period of increased sweating and odor (a sign that my body was purging itself of previous deodorant ingredients, according to the brand). Even then, I was able to mask most of those symptoms with an added swipe of deodorant. Multiple reviewers also acknowledged that their bodies went through a detox period, but Kopari explains that your body should adjust to the deodorant within two to four weeks. As for why the skin experiences side effects in a deodorant swap, Aragona Giuseppe, M.D., G.P., and medical advisor at Prescription Doctor, tells Real Simple, “When switching from an antiperspirant to a deodorant, you are removing the aluminum and releasing waste that has been blocked. This is a natural process as part of our body’s built-in mechanisms, but it may contribute to releasing some slightly unusual body odor in comparison to what you are used to.” She added, “So when you first make the switch, it’s not that your natural deodorant isn’t working—but your body is—and naturally.” After a few weeks of use, I found myself reaching for this product instead of my usual deodorant. And it’s not just me—Kopari shoppers are equally impressed by the product and have left it over 5,800 five-star ratings. “I’ve tried all of the clean deodorants and this is by far the best,” one reviewer wrote. “It doesn’t irritate the skin, there is no white residue, [it] feels soft, and smells amazing. And this lasts forever.” Other long-time natural deodorant users echoed the sentiment that Kopari’s deodorant is “the best,” and one reviewer noted that it “lasts hours.” Reviewers also said they turned to the deodorant for different activities, including working out and spending the day in the office. “I am a personal trainer and I put this deodorant to the test, and it gets five stars from me,” one fan wrote.
