10 Best Natural Deodorants I Tested Day to Day (2025)

Posted on September 24, 2025 by faz_business

These Deodorants Are Just OK

Kopari Performance Plus Deodorant for $20: This deodorant smells great—like a floral, beachy coconut. It’s more fresh than sweet, and I’d say it’s unisex-leaning-feminine. It goes on clear and smooth, and it didn’t stain my clothes at all. However, it didn’t last me through a workout without reapplying, unlike some other brands I tried. I think it’s fine, but I wouldn’t call it a “performance deodorant.” If you’re looking for a clear formula and you don’t mind reapplying, it might be worth a shot.

Fur Ingrown Deodorant for $19: My relationship with this deodorant is as complicated as my relationship with my underarm hair. Sometimes I don’t shave it for months; sometimes I shave it every other day. This deodorant contains ingredients like willow bark (to prevent ingrown hairs) and niacinamide (to brighten underarms). It did both of those things very well. But it didn’t do a great job at preventing odor throughout the day, and the smell is very green and earthy, which didn’t agree with my body chemistry. It might really appeal to some people though—online reviewers seem to love it or hate it—so I recommend smelling it in a store before purchasing.

Curie Clean Deodorant (two-pack) for $28: This formula smells good when first applied, but quickly fades away after an hour or two. It also stained my clothes more than some others I tried. During my second use, it caused some irritation, so I discontinued it. I didn’t notice myself sweating more or less compared to other kinds of natural deodorant. However, the brand does have a great Detox Mask that can help with the transitional period when switching to natural deodorant. It’ll be featured more prominently in an upcoming guide.

Dove Aluminum-Free Deodorant for $11: Dove’s deodorant is mostly fine, and I like how affordable it is. But the texture is really smooth and leaves my underarms feeling strangely sticky, even after letting them dry. The fragrances aren’t powerful or long-lasting enough for my own personal preference. They also all have a powdery undertone that I was not a fan of. I did notice some BO partway through the day during my testing. Since this is so subjective, your mileage may vary. The packaging also came taped shut, and the tape left behind sticky residue on the outside of my deodorant that was impossible to remove without rubbing alcohol.

Lume Whole Body Deodorant (three-pack) for $39: This pricey deodorant smelled terrible to me. I received the Invisible Cream formula in Minted Cucumber, which smelled like pool chlorine and hand soap. I refused to put it on my body. I also received the Clean Tangerine Smooth Solid formula, which initially smelled marginally better but still had a weird hand-soap element to it. It left white marks all over my clothes and oddly smelled like cheese once applied. I washed it off and called my testing done. Reader, I love you, but I’m not going to smell like cheese all day just to see if the smell magically transforms after a few hours. Senior commerce editor Kat Merck also tried the Lavender Sage Invisible Cream, and she said it reminded her of laundry that was left overnight in the washing machine—and that the deodorant made her smell worse than she would have had she not worn any in the first place. Lume does have many fans across the internet, so again, this may be something that can be boiled down to personal preference. I suggest smelling it in a store before purchasing.

Bite Refillable Deodorant for $44: I like the minimalist aesthetic of this refillable deodorant. The sleek metal case is almost miniature, and the entire setup is completely plastic-free. However, it’s easy to push the deodorant stick up too high, which can be messy if the temperatures are warm. In fact, I found the formula too soft in general, and it tended to get gunky and gummy throughout the day, both on my armpits and on the case. I also didn’t love the Neroli scent. I think this could work well if you want the most minimalist, nondescript natural deodorant possible, but there are other refillable options that smell better and last longer.

Saltair AHA Deodorant for $12: I was initially really impressed by the scent I tried from Saltair. Pink Beach smells like a summer sunset on the ocean. Unfortunately, despite my best efforts to make it work, I couldn’t apply this formula without my armpits feeling sticky and irritated. I used it on clean, dry, hairless skin, and I let my armpits dry fully before lowering my arms. But I had this constant feeling of tacky, sweaty irritation that eventually led to a rash, so I discontinued testing.

How I Tested and What’s Up Next

I‘ve been wearing natural deodorant since 2020. I wore each of these deodorants at least three times—once during a calm day at home and twice during a workout at the gym. I also tested whether they stain by putting on a black T-shirt after application. I am currently testing deodorants from Jukebox and additional scents from Megababe, as well as various liquid AHA deodorants.

Common Ingredients, Explained

Here’s an explanation about some of the ingredients you may see in your research.

Aluminum: Natural deodorants (usually) mask odor and don’t emphasize sweat reduction. Antiperspirants (usually) mask odor and prevent sweat. The sweat prevention comes from aluminum salts, which block sweat ducts under your arms. There were a few studies that talked about elevated breast cancer or Alzheimer’s disease risks from using aluminum, but there’s no definite link between them (according to the FDA, the American Cancer Society, and the National Cancer Institute, among others). It’s probably fine to use antiperspirants with aluminum in them. Some people with kidney disease are advised to avoid aluminum, and others want to “play it safe” and avoid aluminum. As for me, I sort of feel better when I sweat? In any case, that’s the lowdown on aluminum. TL;DR: The science says it’s fine for most people.

Parabens: Parabens are preservatives that have been shown to mimic estrogen in the body, but at much lower rates than the body’s natural estrogen. Parabens are somewhat common ingredients in food, medicine, and beauty products, though they’re less common as more people try to avoid them. Some parabens are banned in the EU until more research can be done. The FDA has concluded that parabens are safe. It’s relatively easy to avoid parabens if you choose to. Most antiperspirants don’t contain parabens; most natural deodorants don’t, either.

Phthalates: Phthalates make plastic more flexible and durable, and they can also be used in some beauty products as stabilizers. Some studies have concluded that they’re safe; others suggest links between phthalates and skin irritation, cancer, or early death. But those links were not causal. Phthalates do have a California Proposition 65 warning. The recommended deodorants below are phthalate-free. Many antiperspirants do contain phthalates, but not all of them.

Baking soda: Some natural deodorants use baking soda as an absorptive agent to prevent sweat and as an antibacterial agent to prevent odor. Some people can develop a rash from using baking-soda-based formulas, due to the reaction between the baking soda and their body’s natural pH balance. It’s hard to tell whether or not you’re sensitive to baking soda until you try it, but if you typically have sensitive skin, you may want to try a formula without baking soda. We have some recommendations below.

The Transition Period, Explained

When you make the switch from antiperspirant to natural deodorant, you might go through a transition period lasting from one to four weeks. Long story short, after years of not sweating while using antiperspirants, you might find yourself sweating a whole lot more as your body adjusts when switching to natural deodorant. It’ll level out eventually, but for me personally, I smelled like a gym full of teenage boys for two weeks. Some people don’t have a transition phase at all. I also developed a heat rash from sweating so much during the middle of summer—my skin was irritated, which meant I couldn’t use deodorant at all, therefore raising the Stink Factor. Now, though, I sweat less than I ever did while using antiperspirants.

Be prepared to stick it out. I have an issue with the term “detox,” because our bodies already have a detoxifying process (called the kidneys). However, a clay mask like the Curie Detox Mask can be helpful in drawing out excess moisture and calming down irritated skin that you might experience during the transition period. Otherwise, just keep your underarms dry and be gentle on your skin. It won’t last forever.

It’s hard to empirically test deodorant. Scent preferences vary from person to person, and they can change based on your body chemistry. Some people might prefer a different formula, some people shave and some don’t, and some people care more about sweat absorption than scent. Do you shower every single day? Do you work out frequently? Do you naturally sweat a lot or a little? All of these things can factor in to whether or not you’ll like a deodorant. Here’s what the tables below mean.

Available scents: How many scents you can choose from as of press time.

Free from: These ingredients are not in the deodorant.

Scent strength: “Strong” lasts all day. “Medium” fades halfway through the day. “Faint” means it faded fast or was barely noticeable in the first place.

Sweat level: “Low” means I didn’t notice any sweat. “Medium” means I noticed some sweat but didn’t feel the need to reapply the deodorant. “High” means I sweat a lot and felt the need to reapply throughout the day.

Clothing stains: “None” means it didn’t stain my clothes. “Few” means it might show up on a black T-shirt. “High” means it will absolutely show up on your clothes, regardless of color.

Functional ingredients: A list of the main ingredients that help absorb sweat and prevent odor.

Formula details: Is it vegan? Is it a stick, cream, or roll-on? I’ll let you know here.

13 Best Vibrators of 2025, Tested and Reviewed

Posted on July 31, 2025 by faz_business

Vibrators are some of the most approachable sex toys on the market, but there are so many types of vibrators that it can make even a long-term vibrator owner go a bit mad. From bullet vibrators and the iconic rabbit vibrator to all those funny shaped but deliciously potent vibrators in between, shopping for one can get overwhelming. Luckily, I have a few tips and tricks to help you narrow things down.

First, look at the materials. For vibrators, you want them to be made with 100 percent platinum-cured silicone and/or ABS plastic. Hard glossy plastic is OK for parts that don’t touch your genitals, but platinum silicone is nonporous, easy to clean, and body-safe. Unlike lesser grades of silicone, platinum silicone doesn’t give off any weird smells or compounds that may be unpleasant or even harmful to your genitals. That’s because it’s chemically different from other kinds of silicone. Surgical steel (also called 316 stainless steel), and borosilicate glass are just as body-safe, durable, and nonporous but less common in vibrators and more common in dildos.

Second, look at the charger the vibrator comes with. Is it USB-A, USB-C, or a proprietary AC adapter? I try to keep things simple and stick with vibrators that are USB rechargeable either with USB-A or USB-C. It’s way too easy to lose the charger, and there’s comfort in knowing you can use any charging cable you have lying around. There’s nothing worse than a toy that dies on you mid-use.

Thirdly, when you get your new vibrator, test its vibration strength on the tip of your nose first. You should feel it tickling your nostrils and sinuses, giving you an idea of how deep into your genital tissue it can stimulate. Remember, about 90 percent of the clitoris can’t be stimulated directly because it’s under the skin, so deep vibes are important. The same goes for the phallus—the erectile tissue goes deep into your body, and stimulating it with a vibrator can provide a new and exhilarating experience.

Lastly, consider price—especially if you’re on a budget. Some vibrators can be really expensive based on the features they offer. For example, long-distance devices and suction toys can cost a couple hundred dollars. While a high-quality, body-safe vibrator shouldn’t be cheap, you also want to make sure you’re getting your money’s worth. Make sure to read the specs so you know you’re making a financially wise decision. If a vibrator only has a battery life of one hour, but it’s going to set you back $200, keep looking.

How the Binding of Two Brain Molecules Creates Memories That Last a Lifetime

Posted on July 6, 2025 by faz_business

The original version of this story appeared in Quanta Magazine.

When Todd Sacktor was about to turn 3, his 4-year-old sister died of leukemia. “An empty bedroom next to mine. A swing set with two seats instead of one,” he said, recalling the lingering traces of her presence in the house. “There was this missing person—never spoken of—for which I had only one memory.” That memory, faint but enduring, was set in the downstairs den of their home. A young Sacktor asked his sister to read him a book, and she brushed him off: “Go ask your mother.” Sacktor glumly trudged up the stairs to the kitchen.

It’s remarkable that, more than 60 years later, Sacktor remembers this fleeting childhood moment at all. The astonishing nature of memory is that every recollection is a physical trace, imprinted into brain tissue by the molecular machinery of neurons. How the essence of a lived moment is encoded and later retrieved remains one of the central unanswered questions in neuroscience.

Sacktor became a neuroscientist in pursuit of an answer. At the State University of New York Downstate in Brooklyn, he studies the molecules involved in maintaining the neuronal connections underlying memory. The question that has always held his attention was first articulated in 1984 by the famed biologist Francis Crick: How can memories persist for years, even decades, when the body’s molecules degrade and are replaced in a matter of days, weeks or, at most, months?

In 2024, working alongside a team that included his longtime collaborator André Fenton, a neuroscientist at New York University, Sacktor offered a potential explanation in a paper published in Science Advances. The researchers discovered that a persistent bond between two proteins is associated with the strengthening of synapses, which are the connections between neurons. Synaptic strengthening is thought to be fundamental to memory formation. As these proteins degrade, new ones take their place in a connected molecular swap that maintains the bond’s integrity and, therefore, the memory.

The researchers present “a very convincing case” that “the interaction between these two molecules is needed for memory storage,” said Karl Peter Giese, a neurobiologist at King’s College London who was not involved with the work. The findings offer a compelling response to Crick’s dilemma, reconciling the discordant timescales to explain how ephemeral molecules maintain memories that last a lifetime.

Molecular Memory

Early in his career, Sacktor made a discovery that would shape the rest of his life. After studying under the molecular memory pioneer James Schwartz at Columbia University, he opened his own lab at SUNY Downstate to search for a molecule that might help explain how long-term memories persist.

The molecule he was looking for would be in the brain’s synapses. In 1949, the psychologist Donald Hebb proposed that repeatedly activating neurons strengthens the connections between them, or, as the neurobiologist Carla Shatz later put it: “Cells that fire together, wire together.” In the decades since, many studies have suggested that the stronger the connection between neurons that hold memories, the better the memories persist.

In the early 1990s, in a dish in his lab, Sacktor stimulated a slice of a rat’s hippocampus—a small region of the brain linked to memories of events and places, such as the interaction Sacktor had with his sister in the den—to activate neural pathways in a way that mimicked memory encoding and storage. Then he searched for any molecular changes that had taken place. Every time he repeated the experiment, he saw elevated levels of a certain protein within the synapses. “By the fourth time, I was like, this is it,” he said.

Ozempic and Wegovy Might Be Supercharging Your Taste Buds

Posted on June 1, 2024 by faz_business

Semaglutide, the active ingredient in popular diabetes and obesity drugs Ozempic and Wegovy, can also tweak people’s taste buds for the better, preliminary research suggests. Scientists found that women taking semaglutide improved their taste sensitivity, particularly to sweetness. The findings may illuminate another reason why it and similar drugs can so effectively help people lose weight, the authors say.

The research was led by scientists from the University Medical Center in Ljubljana, Slovenia. They were intrigued by animal studies that appeared to show GLP-1, a hormone key to the body’s control of blood sugar and hunger, also plays an important role in influencing the perception of sweetness. In mice bred to no longer produce GLP-1, for instance, their sensitivity to sweetness seems dramatically reduced.

Semaglutide and other incretins are designed to mimic GLP-1, and some research has found that people on the drug tend to experience a decline in desire for sweet, savory and salty foods. The mechanisms behind this shift aren’t entirely clear, however, so the researchers wanted to see if a similar change in taste sensitivity can happen in humans as well as mice taking semaglutide.

It may sound unintuitive, but increasing taste sensitivity could actually help with weight loss by reducing the desire for excessively sweet, high-calorie foods. By perceiving sweetness more intensely, individuals might feel satisfied with smaller amounts of sugar, leading to a decrease in overall calorie intake.

The team conducted a 16-week-long trial with 30 women volunteers, with half receiving the drug and the other half a placebo. The volunteers had their taste sensitivity measured using strips containing all four basic tastes (sweet, salty, sour, and bitter) placed on their tongue. Additionally, some of their tongue cells were collected to examine gene expression, and they underwent an MRI scan before and after tasting something sweet following a standard meal.

“The present study demonstrated that semaglutide improved taste sensitivity in women with obesity, meaning that the detection threshold for different concentrations of four basic tastes were improved,” lead study author Mojca Jensterle Sever told Gizmodo.

The team also found that the tongue cells of those taking semaglutide experienced changes in the expression of genes linked to the perception of sweetness and the renewal of taste buds. And via the MRI scans, they found changes in how users’ brains responded to sweetness, particularly in the angular gyrus of the parietal cortex. The angular gyrus is thought to help integrate our different senses to better understand the world around us and solve problems, while the parietal cortex is known to have cells that carry GLP-1 receptors.

The team’s findings are being presented this weekend at ENDO 2024, so they haven’t yet undergone the typical peer-review process. Sever notes their research is only a proof-of-concept study, intended to show that there’s something more to explore, not to definitively confirm a phenomenon. Since taste perception can vary significantly between different people, it’s also possible that GLP-1 drugs would not affect everyone’s taste buds the same way.

But research has suggested that at least some people with obesity perceive sweetness less intensely than usual, which might then help drive their craving for even sweeter, often more calorie-filled foods. GLP-1 drugs are thought to help treat obesity in several ways, such as by prompting the sense of fullness earlier into a meal than before. And it’s certainly possible that enhancing people’s sensitivity to sweetness might be another, the authors say.

“Our study provides ‘food for thought’ on the additional mechanisms by which semaglutide and other incretin-based therapies facilitate changes in food preference and eating behavior that might potentially lead to reductions in body weight beyond appetite suppression and improved control of eating,” Sever said.

Future studies, hopefully addressing the limitations of this current research, “will clarify whether the efficacy of semaglutide in treating obesity is also a matter of taste,” she added.
