Best deodorants and antiperspirants of 2024, according to health experts

Best deodorants and antiperspirants of 2024, according to health experts

Sweating is a natural – and necessary – bodily function. It helps prevent overheating, flush out certain toxins, boost circulation and increase immunity. While that's great, and the human body is certainly amazing, there’s a flip side to sweat: body odor. Moreover, a recent study found that our body odor only worsens as we age — unsaturated aldehyde with an unpleasant greasy and grassy odor was detected only in subjects over 40 years old. Luckily, there’s an ever-expanding market dedicated to developing the best antiperspirants, deodorants and combinations of both. In fact, the global market for deodorants and antiperspirants is rapidly expanding and is expected to hit $54.04 billion by 2033.

Quick Overview

The daunting wall of hundreds of antiperspirants and deodorants — and combinations of both — in grocery stores is a prime example of that rapid expansion. With an endless range of products and application types, how does one know which is the best? I find myself wondering: Do I need a deodorant or an antiperspirant, or both? What should I be looking for to find the best deodorant and antiperspirant for me?

To help better understand the method to this madness, I turned to AOL's panel of board-certified dermatologists to learn everything there is to know about deodorants and antiperspirants, starting with the difference between the two.

While it’s always nice to have options, it can also be overwhelming when there are hundreds of products stretching an entire aisle in the drugstore. To help us all find the best deodorant and antiperspirant, with the help of our expert panel of dermatologists' input, we researched more than 75 types and styles of deodorants, antiperspirants and combinations of both —testing quite a few ourselves— and evaluated each based on ingredients, application type, efficacy, scents offered and cost. Keep reading to learn which ones made the cut as the best deodorants and antiperspirants of 2024.

Cost: $20 (or 2 pack for $34 from Amazon) | Active ingredient: Coconut Oil, Tapioca Starch, and Magnesium Carbonate (Dead Sea Salt) | Available for men and women: Gender neutral | Scents available: Lavender & Lemon, Cedar & Vanilla, Cannabis & Green Tea, Cardamom & Ginger, Rose & Vanilla, Citrus & Vetiver, Coconut & Lime, Sandalwood & Black Pepper, Juniper & Mint, and Fragrance-free | Longevity: All Day

Plenty of deodorants on the market are labled specifically for men and women, but the core ingredients are largely the same. The only real difference comes in the form of fragrance; men’s deodorants tend to smell fresh, musky, or earthy; whereas women’s deodorants tend to smell floral, fruity, or summery.

If you have sensitive skin, this may be a real winner for you thanks to being a natural deodorant that's made without aluminum, parabens, baking soda or synthetic fragrance. Instead, it's packed with natural ingredients, such as coconut oil, dead sea salt, tapioca starch, and essential oils. Each & Every Natural also has the "Verified" seal of approval from the Environmental Working Group (EWG), meaning that it does not contain any harsh chemicals, the company is fully transparent about ingredients and practices safe and sustainable manufacturing, so you can trust that the ingredients are safe, clean, and natural.

With a total of 10 different scents to choose from, Each & Every is a true unisex deodorant that costs $20 per stick. Choose a light and airy scent, such as Rose & Vanilla, a strong and rich scent such as Sandalwood & Black Pepper, or something more unique, like Cannabis & Green Tea. And if you’re sensitive to smell, there’s also a fragrance-free option. You can get a two pack from Amazon for $34 but not all scents are available. 

Pros
  • Gentle, non-irritating, EWG-verified formula
  • A variety of scents are available
  • Plant-based packaging
Cons
  • Can leave residue
  • Pricier than drugstore options

Cost: $32 | Active ingredient: Aluminum Zirconium Tetrachlorohydrex Gly 15.40% | Scents available: One | Longevity: All day

Deodorant might not be the most glamorous beauty product on your vanity, but it’s probably the one that gets the most use. So, if you’re looking for an easy way to pamper yourself every day, try swapping out your drugstore deodorant for one of the top luxury antiperspirants on the market: Donna Karan Cashmere Mist. It’s an antiperspirant and deodorant, which means it works to reduce both odor and sweat. It’s formulated with aluminum to block sweat, but the specific aluminum compound used (aluminum zirconium tetrachlorohydrex gly) is gentler on skin than many other aluminum compounds used in antiperspirants. There’s also an aluminum-free version available that uses cornstarch, coconut oil, and magnesium hydroxide, but it’s worth noting that the reviews aren’t nearly as good. Many fans of the original antiperspirant find that the aluminum-free deodorant just doesn’t work as well in terms of staying dry, but that is to be expected since no aluminum means it's not really formulated to keep you from sweating but rather smelling fresh.

Still, no matter which version you choose, you’ll end up smelling great, thanks to the scent. Each stick is infused with the famous Cashmere Mist fragrance: light and fresh with hints of jasmine, bergamot and sandalwood. So, unlike your typical deodorant, it smells more like perfume. 

It's also a personal favorite of our senior health editor, April McCormick, "Hands down Donna Karan Cashmere Mist is one of the best combo deodorant and antiperspirant I've ever used. It keeps me dry and feeling fresh all day, and the scent is heavenly. It's worth every penny and lasts a very long time."

Cost: $18 with subscription; $30 one-time purchase | Active ingredient: Aluminum Zirconium Tetrachlorohydrex Gly 18% | Scents available: 4; Trailblazer, Coastline, Hudson, and Night Market | Longevity: 24 hours

Helmm antiperspirant and deodorant, "designed for the modern man," offers three formulas and four scents to choose from. Along with the antiperspirant, there are two aluminum-free options: the Sport deodorant stick - made with sodium stearate - and the Natural deodorant stick, which contains sodium hydroxide and a blend of plant-based ingredients like sunflower seed oil and aloe vera leaf extract. In addition to the high-quality ingredients, we really liked the company's commitment to sustainability, eco-friendly packaging and its subscription-based service that works on your schedule. The way it works is simple: first, you’ll purchase a starter kit, which comes with a container and a refill pod, or you can opt for a disposable antiperspirant stick. You can then subscribe to get automatic refills every six, seven, or eight weeks. Subscriptions also come with a discounted price on both the starter kit and future pod refills.

We do want to point out that the initial cost can be rather expensive, depending on your chosen starter kit, but the refills are $14-$18 regardless of the starter kit you choose. 

There are two different containers available: 

Compass Vessel ($30): A rubber-coated container that comes in four colors: black, dark blue, light blue and white. It’s priced at $30 for a one-time purchase or $18 for a subscription. 

Heritage Vessel ($80 - $100): Made of metal and hand-stitched leather and comes in black or brown. If you subscribe to the service, the price is discounted to $65-$85.

Refill pods cost $18, but if you opt for a subscription, the cost per refill is $14.

Pros
  • Eco-friendly, refillable design
  • Subscription options for convenience
  • Three formulas to choose from, including aluminum-free
Cons
  • No fragrance-free version available
  • Black leather vessel are significantly more expensive

Cost: $5 - $6 | Active ingredient: Aluminum (Aluminum Sesquichlorohydrate 25% in women’s; Aluminum Zirconium Tetrachlorohydrex Gly 20% in men’s) | Available for men and women: Yes | Scents available: 3 for women (Powder Fresh, Pure Fresh, and Shower Fresh); 4 for men (Clean Control, Intense Energy, Sport and Ice Fresh) | Longevity: 48 hours

If you’re looking for serious perspiration protection at an affordable price, the Mitchum Triple Odor Defense Antiperspirant is a great option.

Formulated with over 20% aluminum, it’s designed to block odor from the three most common culprits: heat, motion, and stress. A solid stick or a gel version is available — personally, I’m always partial to solid deodorants since it tends to dry faster and without any gunky residue, but reviewers for the gel formula note that it’s quick drying and doesn’t leave you feeling like a sticky mess.

Although the scent options are fairly limited – there are three scents for women and four for men – this antiperspirant will leave you smelling fresh and clean and, most of all, you'll stay sweat and stink-free for 48 hours. At less than $10 for a pack of two, this one is hard to best when it comes to getting the most bang for your budgeted buck.

Pros
  • Affordable drugstore option
  • Long-lasting formula
  • Quick drying
Cons
  • No fragrance-free option

Cost: $10 | Active ingredient: Tapioca Starch, Salicylic acid, Zinc ricinoleate, Tamanu oil, and Coconut oil | Available for men and women: Gender neutral | Scents available: 9; Santal Bloom, Pink Beach, Island Orchid, Exotic Pulp, Seascape, Lush Greens, Lagoona, Black Tide, and Fragrance-free | Longevity: 24 hours

While antiperspirants are designed to last 24 hours or more, finding an aluminum-free deodorant with the same staying power is no easy feat. That’s why we’re so impressed with the Saltair Skincare Deodorant.

It’s an all-natural, vegan, and paraben-free deodorant that actually works. In clinical trials, 97% of participants found that one application held up throughout the entire day. What’s more, participants who used the product saw noticeable improvements in skin discoloration and texture. That’s because the Saltair deodorant uses salicylic acid, which helps exfoliate, soften, and brighten skin.

It also contains coconut oil and calophyllum inophyllum oil – commonly known as tamanu oil – which has a number of skincare benefits. Like most nut oils, it’s incredibly moisturizing and is often used to help treat eczema, psoriasis, and irritation. On top of that, both coconut and tamanu oil have anti-inflammatory, anti-microbial, and wound-healing properties.

To help combat sweat and odor, Saltair uses zinc ricinoleate and tapioca starch rather than harsh ingredients like baking soda or alcohol, so it’s safe for all skin types. Of course, it’s worth noting that it’s a deodorant, so it won’t be as powerful as an antiperspirant. So, although it’s long-lasting, if you exercise or work up a sweat, you’ll probably need to reapply.

While you can purchase a two-pack from Amazon for $20, if you opt to order directly through Saltair, you will have access to all the scents available, and other skincare items. 

Pros
  • Helps brighten skin and reduce ingrown hairs
  • Refillable deodorant
  • Variety of scents to choose from
Cons
  • May need to reapply after swimming or a heavy workout
$22 at Amazon

Cost: $14-$16 | Active ingredient: Coconut Oil, Arrowroot Powder, Kaolin Clay, and Baking soda | Available for men and women: Gender neutral | Scents available: 9; Tea Tree, Lemongrass, Vanilla + Citrus, Lavender, Geranium, Blue Tansy, Charcoal, Bergamot + Eucalyptus, and Unscented | Longevity: All day

Antiperspirants can irritate skin due to the aluminum, so a natural deodorant will likely be your best bet for those with sensitive skin. Primally Pure is an organic, all-natural deodorant that is made specifically for sensitive skin. It uses simple, safe ingredients like tallow from grass-fed cows, white kaolin clay, coconut oil, and arrowroot powder to neutralize odors. And although it does contain a small amount of baking soda, it’s naturally mined and has a finer grain than traditional baking soda so it’s less abrasive and won’t cause irritation.

There are nine scents to choose from, including several gender-neutral options: Tea Tree, Lemongrass, Vanilla + Citrus, Charcoal, Bergamot + Eucalyptus, and Unscented. However, it’s worth noting that the scented deodorants use essential oils for fragrance, which can be irritating for some people, so if you have extra sensitive skin, it’s a good idea to try the unscented deodorant first, which is free of any fragrance additives.

Pros
  • Affordable price
  • Controls sweat and odor effectively for over 24 hours
  • Quick-drying formula
Cons
  • Leaves some residue
  • Gender-specific formula
$14-16 at Primally Pure

Cost: $14 | Active ingredient: Aluminum Chlorohydrate 19% and Bisabolol | Available for men and women: Gender neutral | Scents available: One; Fresh | Longevity: 24 hours

The Uriage Power 3 Deodorant is a clinical strength, roll-on antiperspirant that’s designed to block sweat for 24 hours. It only comes in a roll-on form, but that’s not necessarily a bad thing. Roll-ons tend to be extremely effective thanks to the liquid consistency that not only delivers more of the active ingredient directly to the area, it's easily absorbed into the skin. Dr. Kaniszewska tells us, "Aerosols and wipes may not be as effective than a thicker gel or cream that has the ability to stay on the skin and absorb better."

The downside, though, is the wet feeling upon application can be off-putting and it can take longer to dry. The deodorant is made from Uriage Thermal Water, which helps nourish and moisturize underarm skin, along with bisabolol — a plant-based ingredient that can reduce redness and irritation. The Power 3 Deodorant is hypoallergenic and alcohol-free, so it’s a gentler option for anyone who prefers the stain-free, odor-blocking benefits of a roll-on.

Pros
  • Alcohol-free antiperspirant
  • Clean, gender-neutral scent
  • Controls sweat and odor well
Cons
  • Takes some time to dry

Cost: $10 | Active ingredient: Aluminum Sesquichlorohydrate 18% | Available for men and women: Gender neutral | Scents available: 5; Clean, Fresh, Marine, Bold, and Neutral | Longevity: up to 96 hours

Degree is one of the most popular, well-known antiperspirant brands on the market and for good reason: The stuff works. 

Unlimited by Degree is a new dry spray antiperspirant-deodorant hybrid that keeps you stink-free for up to 96 hours. That’s four days! It features the brand’s exclusive SmartAdapt technology, which works to adapt and respond to your body to create a barrier against sweat and odor. Basically, this micro-barrier is activated in response to movement, heat, and stress. So, you’ll get extra protection during moments when you need it the most (like when you’re at the gym.)

There are five different scents available that range from clean and airy to bold and warm. And, if you’re not up for a dry spray, it comes in a solid stick as well.

Pros
  • Doesn’t leave white residue
  • Long-lasting sweat protection
  • Five, gender-neutral scent options
Cons
  • No fragrance-free option

Cost: $20 | Active ingredient: Probiotics, Spirulina, Hyaluronic Acid, Antioxidants, Tapioca Starch, Magnesium Hydroxide, Baking Soda, and Coconut Oil | Available for men and women: Gender neutral | Scents available: 4; Santal & Vetiver, Bergamot & Hinoki, Black Rose & Oud, and Neroli & Basil | Longevity: All-day

If you’ve been on Instagram or TikTok lately, chances are you’ve seen the viral deodorant from Salt & Stone. The Salt & Stone Natural Deodorant is crafted with a ton of all-natural, good-for-your-body ingredients like probiotics, magnesium, and coconut oil. It uses antioxidants, like seaweed and spirulina, to protect and soothe irritated skin and hyaluronic acid to help gently exfoliate and brighten your underarms. But perhaps more impressively, it contains probiotics, which work to balance the skin’s microbiome and prevent odor.

It’s gender-neutral and comes in four delectable scents. And these aren’t your typical deodorant scents, either. The scents are unique and sophisticated – like Black Rose & Oud, which has notes of lily, mahogany, amber and black rose. There’s no fragrance-free option, but there is a gel formula if you have more sensitive skin.

Pros
  • Probiotics help rebalance skin microbiome
  • Softens underarm skin
  • Vegan, cruelty-free formula with no alcohol or parabens
Cons
  • Contains some baking soda
  • Pricey

Cost: $11 - $14 | Active ingredient: Aluminum Zirconium Trichlorohydrex Gly 20% | Available for men and women: Gender neutral | Scents available: 4; Barca, Clear Sky, End Game, and Limitless | Longevity: 24 hours

If you need something with serious sweat protection, Duradry’s AM Antiperspirant stick is a clinical-strength antiperspirant-deodorant combo that was made to treat Hyperhidrosis, or excessive sweating.

It contains 20% aluminum zirconium trichlorohydrex gly, which is the max strength for that aluminum compound allowed by the FDA in OTC antiperspirants. Of course, that might be too drying and irritating for some, but if you have hyperhidrosis or are someone who sweats a lot, this product is worth a try.

There are four gender-neutral scent options available that range from clean and powdery to warm and earthy. It’s priced at less than $14, but you can save even more if you opt to subscribe to the auto-delivery service($11). Subscriptions can be delivered every month, every three months, or every six months.

Pros
  • Strong sweat protection
  • Smells great
  • Formulated with 75% natural ingredients
Cons
  • Leaves some residue
  • Can be drying

Cost: $31 | Active ingredient: Aluminum Zirconium Tetrachlorohydrex Gly 11.25% and Kojic Dipalmitate | Available for men and women: Gender neutral | Scents available: Only available as fragrance-free | Longevity: All day

Have you ever noticed a product labeled ‘unscented’ that definitely still has a smell? If so, you’re not alone, we have too. That’s why we love the DERMAdoctor Total Nonscents Ultra-Gentle Brightening Antiperspirant for a truly fragrance-free deodorant.

Total Nonscents is a roll-on antiperspirant that has a seriously small list of ingredients — Seven! Most antiperspirants – and even the "natural" deodorants – have at least 10 ingredients. One of our favorite ingredients is the kojic dipalmitate, a compound that works to help brighten underarm skin.

The price point is definitely one of the higher ones on the list at $31, but it's worth it if you have sensitive skin. It’s a water-based antiperspirant that’s extremely gentle and non-irritating, not to mention completely unscented – so if you find most antiperspirants too harsh, this is one to try.

Pros
  • Gentle, non-irritating antiperspirant
  • Helps brighten and even underarm skin
  • Goes on clear
Cons
  • Lower amount of aluminum than other antiperspirants
  • Very pricey

Cost: $26 | Active ingredient: Diatomaceous Earth and Tapioca Starch | Available for men and women: Gender neutral | Scents available: 6; Nº Green, Third Rose, Santalum, Cedar Flora, California, and Neroli | Longevity: All day

The Corpus Naturals Deodorant Stick is another social media viral product that’s worth the hype. It’s an all-natural, vegan, and cruelty-free deodorant that’s made without aluminum, baking soda, or synthetic fragrance. Instead, it uses vegetable-derived enzymes and plant-based ingredients, such as diatomaceous earth and tapioca starch to kill odor-causing bacteria and neutralize sweat.

But the best part is the look and feel. The deodorant stick comes in a chic, pistachio green container that looks incredibly elegant on your dresser. It’s a water-based gel formula that glides on smoothly without leaving any annoying white marks. Then there’s the smell — Corpus Naturals only uses naturally-sourced fragrance from essential oils and plant isolates and the results are incredible.

There are six scents available and all smell amazing. The scents are subtle, long-lasting, and gender-neutral – plus, if you can’t decide, you can get a mini set of three or siz to find the best fragrance for you.

Pros
  • Gentle, water-based formula
  • Goes on smooth
  • Smells great with no synthetic fragrances

It’s all-natural formula is free from aluminum, parabens, sulfates, and baking soda.

Additionally, the coconut and sage oils are antimicrobial and antibacterial, which eliminate and neutralize body odor while also moisturizing and soothing the skin.

When searching for the best antiperspirant and deodorant for you, keep the following important factors in mind:

Antiperspirant vs Deodorant: The biggest thing to consider is whether you want an antiperspirant or a deodorant. People often use the terms interchangeably, but they’re not the same thing. Antiperspirants block sweat, whereas deodorants block and mask odors, not sweat. It's also important to know that while most antiperspirants are also deodorants, not all deodorants are antiperspirants, so be sure to read the labels.

The main difference can be found in the ingredients. Antiperspirants contain aluminum salts, which dissolve into your pores and effectively prevent you from sweating. Deodorants, on the other hand, are aluminum-free and instead use antibacterial ingredients, such as baking soda or propylene glycol, that work to neutralize odor.

Ingredients: If you have sensitive skin, allergies, or eczema, you’ll want to choose a product without harsh chemicals or irritants, such as triclosan, propylene glycol, and alcohol. It’s also worth noting that these ingredients can be found in both antiperspirants and deodorants.

If you want something that will keep you dry throughout the day and even workouts, you’ll need an antiperspirant with aluminum, but to make things even more confusing, not all aluminum is created equally. There are 18 different FDA-approved aluminum compounds that can be used in antiperspirants, although some are more common than others. Aluminum chloride, for example, is considered the most effective for hyperhidrosis and heavy sweaters, but it’s also more irritating. Aluminum zirconium and aluminum sesquichlorohydrate are gentler forms to consider.

Dr. Tushar Dabade, a board-certified dermatologist, points out that "Prescription antiperspirants have a higher percentage of aluminum chloride than non-prescription. Prescription antiperspirants may work a little bit better for some people, but occasionally can cause irritation."

Application type: Deodorants and antiperspirants come in a variety of application types. Each type has pros and cons, but the best one for you will depend on your personal preference.

  • Solid: The most common type (and my go-to) is a solid stick with a powdery, smooth consistency. Solid deodorants tend to dry quickly but can also leave some residue behind. If that’s a concern, you can opt for an invisible solid with the same consistency but goes on clear.

  • Roll-on: Roll-on deodorants are liquid and have a rotating ball applicator that contours to your underarm. They’re usually smaller and more compact, plus they go on clear and don’t leave any white marks behind. The downside is that they take time to dry, can feel sticky, and can be drying on your skin.

  • Spray: Aerosol deodorants dry quickly and offer a mess-free, convenient application. However, they’re also bulkier and tend to be depleted faster.

  • Gel: Gel deodorants typically come in the same type of container as solid sticks, but have a thick, liquid consistency. Gels can be messier and take longer to dry, butgenerally go on clear without leaving residue behind.

  • Cream: Like gel, cream deodorants have a semi-liquid consistency, but are typically thicker and smoother. Cream deodorants are usually applied with the fingers instead of through the container, so it can be messy to apply, but more moisturizing for the skin then other application options.

  • Wipe: Deodorant wipes are disposable, single-use wipes, similar to baby wipes. Wipes offer speed and convenience, but since each wipe is used only once, it can be pricier.

While application type does come down to preference — the best product is the one you will use — keep in mind our expert Dr. Kaniszewska cautions that aerosols and wipes may not be as effective as a thicker gel or cream that tend to stay on the skin and absorb better.

Strength: When it comes to strength, it really only applies to antiperspirants. Stronger antiperspirants, often labeled ‘clinical strength,’ have a higher percentage of aluminum. A clinical-strength antiperspirant, for example, may have 20% aluminum zirconium whereas others have between 12% and 15%. If you have hyperhidrosis or spend a lot of time in high heat or being active, it’s a good idea to look for an antiperspirant with clinical strength levels of aluminum.

Longevity: Stronger antiperspirants will generally last longer, with some even boasting 24-48 hours or more of coverage. However, natural, aluminum-free deodorants may not last the entire day and do not prevent sweating as well as aluminum-based antiperspirants.

Still, Schieber stresses that, "Everyone’s needs for deodorants and antiperspirants are different. What lasts for 24 hours for one person might not last for 24 hours for the next."

Scent: The type of scent you want will depend on what you like. Some people might prefer fresh, clean, powdery scents, while others may want something rich and warm, floral or earthy. Another thing to consider is what’s available — some brands offer a range of scents, while others only offer a few options. And not every deodorant brand offers an unscented version. Fragrance can also cause some skin irritation, so if you have sensitive skin, a fragrance-free deodorant may be a better fit.

Cost: Drugstore deodorants typically cost between $5 and $15, while luxury, high-end deodorants can cost upwards of $25 to $40. With some luxury deodorants, you’re paying for the brand name, but the higher price also often reflects high-end packaging, quality ingredients and more decadent fragrance options.

To find the best deodorants and antiperspirants, we first spoke to a panel of dermatologists and their physician assistants to determine what to look for in a deodorant and what to avoid. All agreed that the most important consideration is a product’s ingredients, so we spent hours comparing ingredient lists of more than 75 products and looking at the scientific research available.

For antiperspirants, we looked at the type and percentage of aluminum salt used along with the inactive ingredients and prioritized those without ethyl alcohol, parabens, or harsh irritants. For aluminum-free deodorants, we looked for products with natural, plant-based ingredients. Finally, we evaluated more than 75 products, from popular drugstore brands to luxury brands, and lesser-known brands with exceptional products, rating each based on ingredients texture, application, efficacy, scent, and cost.

While the terms are often used interchangeably, antiperspirants and deodorants aren’t the same. Dr. Monika Kaniszewska, the board-certified dermatologist, tells us in the simplest terms, "Deodorants mask the odor, while antiperspirants prevent you from sweating." It’s a subtle difference that comes down to one key ingredient: aluminum.

Antiperspirants are formulated with aluminum salts, which work by forming a temporary plug in the sweat ducts - specifically the eccrine glands - thus preventing you from sweating, explains Dr. Amy Forman Taub, board-certified dermatologist and founder of Advanced Dermatology. "What sets different antiperspirants apart is which salt the product is formulated with and its concentration. While aluminum salts can be irritating, aluminum sesquichlorohydrate is less irritating than products that contain aluminum chloride, yet weaker," says Dr. Taub.

Deodorants, on the other hand, don’t contain aluminum but instead use alternative ingredients - tapioca starch, baking soda, sea salt - and fragrances such as coconut oil, jasmine, cedar or lavender to prevent odor. Depending on the type of deodorant you choose, it may also be fortified with peptides, brightening serum, moisturizers and exfoliators.

There are plenty of myths surrounding the safety of aluminum-based antiperspirants. It’s been suggested that aluminum can cause various ailments and disorders, most notably Alzheimer's disease and breast cancer. However, it’s worth noting that there is no evidence that antiperspirants cause any health concerns, including finding no link between antiperspirant use and breast cancer.

According to dermatologist and founder of DermGPT, Dr. Faranak Kamangar, aluminum-based antiperspirants are considered extremely safe and effective. Dr. Zenovia Gabriel, a board-certified dermatologist from California, agrees but adds that there is a risk of skin irritation for those with allergies or sensitive skin.

The armpit area is prone to sweat and friction, which can cause irritation. This area is also considered an "occluded" area, meaning it has limited airflow and can lead to increased penetration of topical products that may irritate sensitive skin, Dr. Minars tells Yahoo. As a result, "something that may not penetrate enough to irritate your hand, for example, will penetrate more and maybe irritate your underarm," he adds.

People with sensitive skin should avoid deodorants containing fragrances, high alcohol content, aluminum compounds, parabens, and baking soda. These ingredients can cause irritation and discomfort for those with sensitive skin, says Dr. Navin Arora, a board-certified dermatologist and Founder of Borealis Dermatology.

Many women turn to men’s deodorant, thinking that the products are stronger or more powerful, but that’s another myth.

“The active odor-fighting ingredients are actually the same,” says Dr. Samuel Hetz, medical director of Concept Medical. Instead, he says, the difference usually comes down to fragrance. “Men’s products tend to take on a stronger, muskier scent while women’s are often lighter and more floral.” Because of that, men’s deodorant can often seem like it works better. “A more potent scent better masks odors,” he says, explaining that added scents tend to become stronger and more noticeable when you sweat.

Although most people apply antiperspirants and deodorant first thing in the morning, that may not be the most effective option. “Antiperspirants are actually best applied before bedtime,” says Dr. Kamangar. At night, your body temperature is lower and your underarm area is drier, so antiperspirant will be able to penetrate your pores more easily, allowing it to work better.

However, that’s only the case for antiperspirants. If you use an aluminum-free deodorant, morning application is recommended. Additionally, Dr. Kamangar advises applying deodorant after your morning shower when your skin is clean and dry. “This can help ensure better adhesion and effectiveness of the deodorant throughout the day.”

Antiperspirants should really only be applied once a day, says Dr. Kamangar, adding that because of the aluminum, applying more often can increase the risk of skin irritation. Deodorant, however, is a different story. Since there’s no active ingredient, you can reapply as often as needed throughout the day in order to control odor. Additionally, your activity can play a role. “If you exercise or take a shower, it’s advised to reapply,” says Dr. Gabriel.
