The 12 best deodorants and antiperspirants for women in 2024

The 12 best deodorants and antiperspirants for women in 2024

More than 300 million Americans include a swipe or two of deodorant and antiperspirant in their daily routine. In fact, dollar for dollar, the United States uses more deodorant than any other country. But we are using the term deodorant loosely. There is a big difference between a deodorant and an antiperspirant, according to Steven Prus, PA-C, a physician assistant at Advanced Dermatology. "Deodorant just masks odor, while antiperspirant is a compound that decreases perspiration," he explains. The compound in antiperspirants that reduces or altogether eliminates sweating is aluminum.

Quick Overview

Amy Forman Taub, MD, FAAD, board-certified dermatologist and founder of Advanced Dermatology tells us that in order to be called an antiperspirant, it is required to have aluminum salts. "Aluminum salts work by blocking sweat ducts, specifically the eccrine glands. 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," she explains.

While there is a big difference between deodorant and antiperspirant there is minimal difference between men's and women's versions of each. Generally, there is no difference in the strength of deodorant, says Dr. Samuel Hetz, medical director of Concept Medical. "The active odor-fighting ingredients are actually the same." He explains that 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 offer a floral scent.

With so many brands and application types — like sticks, sprays, wipes, creams and roll-ons — finding the best deodorant and antiperspirant can sometimes feel overwhelming. Factor in labels promoting different benefits — antiperspirant, deodorant or a blend of both — along with options like aluminum-free formulas and natural deodorants, and the decision becomes even more complex. So how in the world do you choose the best defense for your armpits? You keep reading.

The team here at AOL has been hard at work talking with our panel of dermatologists and skin care experts to get their take on the sea of sweat- and stink-stomping products. We discussed what ingredients to look for that actually work to keep you dry and smelling fresh and then researched and evaluated countless deodorants and antiperspirants. We were looking for the key ingredients our experts called out, like aluminum, baking soda and arrowroot, that are proven to keep you dry or absorb moisture. We also considered products with moisturizing and odor-fighting ingredients like coconut oil, aloe vera and essential oils. Throughout our research, preference was given to cost-effectiveness and staying power, as well as the quality of ingredients, while omitting those with harsh chemicals and known skin irritants. Based on the research and testing of our panel of medical experts and AOL editors, below you'll find our list of the best deodorants and antiperspirants for women that will keep you dry and smelling fresh all day.

Cost: $7 | Type: Solid | Active ingredient: Aluminum zirconium | Scents available: Hygienic Fresh, Completely Clean, Protecting Powder | Features: Invisible, PETA-certified, PH-balancing minerals | Longevity: 48 hours

When it comes to women's deodorants and antiperspirants, Secret is one of the most well-known names, and for a good reason: it works. Its Outlast sweat and odor protection stick formulation boasts a whopping 19% aluminum zirconium. "When treating excessive sweating, a higher aluminum concentration (12% - 30%) in antiperspirant is required," says Dr. Taub.  

Secret's Outlast offers 48 hours of sweat-blocking protection and comes in three scents: Hygienic Fresh, Completely Clean, Protecting Powder. The stick deodorant swipes on clear and has yet to transfer or leave marks on my clothes or our testers. It stands up to long days and even though I sweat at the gym, I don't come out smelling like BO is my signature scent. It's also a PETA-certified cruelty-free deodorant and is paraben-free, however, it does contain alcohol and synthetic fragrances, so this one may not be a great fit for those with sensitive skin. 

Pros
  • 48 hours of sweat-stomping protection
  • Helps prevent odor-causing bacteria
  • Paraben-free
Cons
  • Contains alcohol
  • Synthetic fragrances

Cost: $20 | Type: Solid | Active ingredients: Coconut oil, tapioca starch, and magnesium carbonate (Dead Sea Salt) | 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: 8-12 hours before needing to reapply

If you have sensitive skin or want to avoid aluminum and baking soda, Each & Every's all-natural aluminum-free deodorant may be a real winner. It'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. 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.

Pros
  • Gentle, non-irritating
  • Plant-based packaging
  • moisture absorbing and odor-blocking
Cons
  • Does not go on clear, so will leave residue on clothing

Cost: $18 | Type: Solid | Active ingredients: Coconut oil and sage oil | Scents available: Original, Driftwood, and Beach | Features: Made without aluminum, parabens, sulfates and baking soda | Longevity: 8-12 hours before needing to reapply

Kopari deodorant is an organic, non-toxic, plant-based and all-around skin-friendly deodorant. The all-natural formula is free from aluminum, parabens, sulfates and baking soda, making it safe, clean and gentle enough for children's skin. The deodorant contains coconut water, coconut oil and sage oil to keep you smelling fresh. Additionally, the coconut and sage oils are antimicrobial and antibacterial, which eliminate and neutralize body odor while simultaneously moisturizing and soothing the skin. This was the first deodorant my pre-teen tried and he was great about using it. Partly because he loved feeling like a big guy who used deodorant like his dad, but also because he was able to notice the difference in odor protection between his body odor and his friends who were still depending on showers to keep them from smelling. 

Kopari also makes a Performance Plus 24-hour deodorant that, while not a top pick for ultra-sensitive skin, is a great option for those who need a little more odor protection and moisture absorption.

Pros
  • Aluminum, baking soda and alcohol-free
  • Moisturizing formula
  • Goes on smooth
Cons
  • Not as long-lasting
  • limited scents available

Cost: $5 - $6 | Active ingredient: 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: $5.57 | Type: roll-on | Active ingredient: 12% Aluminum Chloride | Scents available: Unscented | Features: Unscented, near prescription strength | Longevity: 72 hours

Certain Dri Clinical Strength Antiperspirant prioritizes keeping you sweat-free over all else. Its formula uses aluminum chloride, which is the most powerful of the aluminum salts found in most prescription antiperspirants. Unlike other antiperspirants, you apply Certain Dri at night rather than in the morning to allow the aluminum time to absorb into the skin and sweat ducts. Certain Dri also sells stick and aerosol antiperspirants, but its roll-on is one of its strongest products featuring aluminum chloride. I have long used Certain Dri and reach for this when I wear a shirt that can easily show sweat or I am facing a long day of meetings and high-stress situations, and it never lets me down. If you struggle with sweating through your clothes, this is well worth a try.

We do want to warn that it can cause skin irritation for those with sensitive skin, or if used on damaged or otherwise irritated skin. Avoid use immediately after shaving. It's also important to speak to your doctor if you are concerned that your sweat is overly excessive.

Pros
  • Powerful protection
  • Available as a roll-on, stick or spray
  • Last 72 hours
Cons
  • May irritate sensitive skin
  • Only unscented available

Cost: $14 | Type: Solid | Active ingredients: Corn starch, saccharomyces ferment filtrate, willow bark extract, botanicals | Scents available: Rosy Pits | Features: Aluminum-free, water-based with skin nourishing ingredients, dermatologist-approved | Longevity: 8-12 hours before needing to reapply

Megababe's Rosy Pits Deodorant deserves an all-star spot for sensitive skin. It’s loaded with gentle yet effective ingredients like saccharomyces ferment filtrate (a soothing type of fermented yeast) for odor protection, willow bark for wetness protection, and skin-nourishing colloidal oatmeal. One of my favorite aspects of this deodorant is that the water-based stick glides on smoothly without tugging and irritating the skin. It contains vitamin E to protect against razor burn and irritation, so like many antiperspirants you can't use on broken or freshly shaved skin, there's no need to worry when swiping this on after a shower. Best of all, it's been clinically tested for sensitive skin and is dermatologist-approved. As for keeping me dry and smelling fresh, the combination of corn starch and saccharomyces ferment does a great job of absorbing both my sweat and odors.

If you need sweat protection, this may not be the best option as it does not contain aluminum. 

Pros
  • Goes on clear
  • Clinically tested for sensitive skin
  • Vegan-friendly
Cons
  • Only one scent

Cost: $10 | Type: Aerosol spray | Active ingredient: Aluminum Sesquichlorohydrate | Scents available: Clean, Fresh, Marine, Bold and Neutral | Features: 96 hours of sweat protection, smart-adapt technology, unisex | Longevity: Up to 96 hours

Aerosol deodorants are easy to apply and don't leave a thick smear on your skin or clothes. Unlimited by Degree is a new dry spray antiperspirant-deodorant that keeps you sweat and stink-free for up to 96 hours. That’s four days! It features the brand’s exclusive SmartAdapt technology which adapts and responds to your body to create a barrier against sweat and odor. Essentially, a micro-barrier is created by the spray to provide extra protection when you need it the most — at the gym, running errands, or during marathon meetings. And for those that don't love the way sprays can be cold and run down your sides, this sprays on almost like a powder, so while it is still cool when it hits your skin, it covers well and stays put. 

As for how well it works, it is effective, but none of our testers were able to go the full four days without a shower. One tester avoided reapplying during the four days but was not confident in the results. They couldn't tell if showering washed the spray away or if it simply didn't last. Our experts say, aluminum will build up over time and usually can take anywhere from a week to three weeks to detox the aluminum from your sweat glands, so with enough use, four days of protection is certainly possible.

If you’re not up for a dry spray, it comes in a solid stick.

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

Cost: $14 | Type: Roll-on | Active ingredients: Aluminum chlorohydrate and bisabolol | Scent available: Fresh | Features: Thermal Water and bisabolol to nourish skin and reduce irritation | Longevity: 24 hours

The Uriage Power 3 Deodorant is a clinical-strength, roll-on antiperspirant designed to block sweat for 24 hours while nourishing the skin to reduce irritation. It's made with aluminum chlorohydrate to block sweat while Uriage's proprietary thermal water nourishes and moisturizes underarm skin. Bisabolol, a plant-based ingredient, can reduce redness and irritation. 

It only comes in a roll-on form, but that’s not necessarily a bad thing: a roll-on's liquid consistency is more easily absorbed into the skin than a solid stick or aerosol. The downside, though, is the wet feeling upon application can be off-putting and it can take longer to dry. This has all the makings to be a great, non-irritating antiperspirant, but the roll-on did feel wet and you need to give it about three to four minutes to dry. That said, the thermal water and bisabolol are worth the wait according to one tester,

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

Cost: $10 or 2 pack for $20 on Amazon | Type: Solid | Active ingredients: Tapioca Starch, salicylic acid, zinc ricinoleate, tamanu oil, and coconut oil | 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 and 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

Cost: $20 for 3oz tube or $30 for 5 .05oz sampler pack | Type: Cream | Active ingredients: Mandelic acid, maranta arundinacea root powder, cacao (cocoa) seed butter, tapioca starch | Scents available: Minted Cucumber, Soft Powder, Lavender Sage, Toasted Coconut, Peony Rose, Clean Tangerine, Unscented, Fresh Alpine | Features: Aluminum-free whole body deodorant, nourishing, all-natural | Longevity: 72 hours

Lume's whole body cream deodorant rubs in like a lotion and works to keep you dry and smelling fresh for a full 72 hours. The cream formula is a doctor-developed aluminum-free deodorant safe for external use. It's also fortified with cocoa seed butter, so you get the moisturizing benefits of a lotion and odor control in all your hard-to-reach and sensitive areas. And for those with sensitive skin, Lume's whole body cream is aluminum-free, baking soda-free and paraben-free, as well as hypoallergenic and safe for use anywhere and everywhere. 

Our tester loved the option to put this absolutely anywhere and said, at first, the smell of each was a little off-putting, but once it dried, small wafts of lavender or coconut shone through. By the end of the day, she could still smell light hints of the fragrance. It did not seem like something you'd want to slather over your body daily.

If you need serious sweat-blocking power, Lume also offers a cream that contains aluminum, but it may be irritating to sensitive skin and sensitive areas,

Pros
  • Hypoallergenic for whole body use
  • Rubs in like lotion
  • Blocks odor for up to 72 hours
Cons
  • Pricey
  • Aluminum version scents are limited

Cost: $13 | Type: Wipes | Active ingredient: Coconut milk, witch hazel, shea butter | Scents available: Fragrance-free with a hint of coconut | Features: 30-wipes per pack, free from aluminum, mineral oil, parabens, petrolatum, phthalatesand sulfate | Longevity: 8 - 12 hours before needing to reapply

If the idea of a deodorant wipe is new to you, prepare to be enlightened! Pacifica Beauty's underarm deodorant wipes can be used to wipe away existing odors or after showering to stop future smells from seeping through. Formulated with coconut milk, witch hazel and shea butter to both nourish and prevent odor, the wipes are free from aluminum, parabens, phthalates, mineral oil, petrolatum or sulfates. The only downfall is that the wipes do contain a little natural grain alcohol, so they may not suit those with ultra-sensitive skin. Each pack comes with 30 wipes.

I have used these wipes to eliminate existing odors after a workout and after a shower, and I loved the results in both situations. These deodorant wipes are an official staple in my summer bag.

Pros
  • Eliminates odors
  • Nourishing
  • Convenient for on-the-go use
Cons
  • Only one scent
  • Contains grain alcohol that could irritate sensitive skin

Cost: $32 | Type: Solid | Active ingredient: Aluminum zirconium | Scents available: Cashmere Mist | Features: Antiperspirant and deodorant that smells like Donna Karan Cashmere Mist perfume | Longevity: 24 hours

Donna Karan Cashmere Mist Anti-Perspirant works to reduce both odor and sweat. Formulated with aluminum zirconium — a gentler aluminum compound than what's used in many drugstore brands — it works to stop sweat before it starts while keeping you smelling like the beloved Cashmere Mist fragrance: light and fresh with hints of jasmine, bergamot and sandalwood.

I have long been a fan of both the Cashmere scent and this deodorant. It is my guilty pleasure and I reach for it before going out for a date night, to dinner with friends or when I want to feel fancy and pretty. It works to keep me both dry and smelling like Cashmere all day and night. It is definitely not cheap but one tube will last me about three to four months with regular use.

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.

Pros
  • Smells just like the beloved Cashmere Mist perfume
  • Made with the gentler Aluminum that keeps you dry with less irritation Zirconium tetrachlorohydrex gly
Cons
  • Only available online and at department stores

Cost: $31 | Type: Roll-on | Active ingredients: Aluminum Zirconium Tetrachlorohydrex Gly 11.25% and Kojic Dipalmitate | Scents available: Only available as fragrance-free | Longevity: 24-hours

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 with 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

When searching for the best antiperspirant and deodorant, consider the following important factors:

Before shopping, decide if you want to stop sweat (antiperspirant), block odors (deodorant), or both (deodorant and antiperspirant).

  • Antiperspirants: 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, whereas aluminum zirconium and aluminum sesquichlorohydrate are gentler forms. "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 Taub. Dr. Tushar Dabade, a board-certified dermatologist, points out that "prescription antiperspirants have a higher percentage of aluminum chloride than nonprescription. Prescription antiperspirants may work a little bit better for some people but occasionally will cause irritation."

  • Deodorants: Deodorants can have a long list of ingredients, so if you have known allergies to topical ingredients, make sure to read the label. Since deodorants do not contain aluminum, the majority are fortified with ingredients that absorb moisture, such as arrowroot powder, cornstarch or baking soda. When it comes to fighting odors, deodorants will either lean into synthetic fragrances or they'll utilize coconut milk or oil, shea butter or essential oils.

Deodorants and antiperspirants come in various application types. When it comes to deciding which is best, Dr. Monika Kaniszewska, a board-certified dermatologist, says, "Aerosols and wipes may not be as effective as a thicker gel or cream that has the ability to stay on the skin and absorb better."

  • Solid: The most common type for both antiperspirants and deodorants. It usually has a powdery soft, solid and smooth consistency. Solid deodorants tend to dry quickly but can also leave residue behind if not formulated to be "invisible."

  • Roll-on: Roll-on deodorants have a liquid consistency and are applied using a rotating ball applicator that disperses the product as you roll it across your skin. The benefit is that it goes on clear and absorbs more quickly than a solid; the downside, however, is that it takes longer to dry than a solid, so you may feel wet or sticky until it completely dries.

  • Spray: Spray or aerosol deodorants are easy to apply and dry quickly. However, aerosol deodorants are bulkier and tend to deplete faster than solids.

  • Gel: Gel deodorants typically come in the same type of container as solid sticks but have a thick, gel consistency. Like roll-ons, gels take time to dry, but they go on clear and leave little residue behind.

  • Cream: Cream deodorants are becoming all the rage because they are safe to apply to your whole body, not just your armpits. The consistency is comparable to that of your favorite lotion and is just as moisturizing.

  • Wipe: Deodorant wipes are disposable, single-use wipes that are great for on-the-go use to get rid of and prevent future odors. The downside is that wipes are expensive and you will likely run through a pack of 30 wipes three times faster than a standard solid stick of deodorant.

Strength mainly applies to the antiperspirant's use of aluminum. Stronger antiperspirants, often labeled as "clinical strength," have a higher percentage of aluminum. As for longevity, stronger antiperspirants will also last longer, with some even boasting 48 to 72 hours of sweat prevention. Natural, aluminum-free deodorants, on the other hand, may not last the entire day without reapplying. "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," says Ann Cameron Schieber, PA-C, a physician assistant at Advanced Dermatology.

Scent comes down to personal preference and your skin's level of sensitivity. During our research, we learned there is a seemingly endless range of pleasant scents when it comes to antiperspirants and deodorants, especially when you add in the versions marketed to men. This is one of those features for which you may need to spend time in the deodorant aisle of the drugstore, sniffing out your favorite scent. If you have sensitive skin, look for natural deodorants that offer essential oils and botanicals in lieu of synthetic fragrances.

As you can see from the list above, there is a broad range of prices when it comes to deodorants and antiperspirants, and it doesn't always come down to a you-get-what-you-pay-for situation. There are plenty of effective products that cost under $5. The cost rises for luxury deodorants with a brand name, or all-natural formulations that offer high-quality organic ingredients. The good news is that in general, deodorants can last a very long time, so you'll usually find that regardless of what you choose, you do get the most bang for your buck.

To find the best deodorants and antiperspirants, we first spoke to a panel of physicians, dermatologists and physician assistants to determine what to look for in a great deodorant and antiperspirant, 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 in the formulation along with the inactive ingredients. We avoided those that contained ethyl alcohol, parabens and harsh irritants. For deodorants (aluminum-free), we looked for products with natural, plant-based ingredients, including organic ingredients where possible. We also evaluated each product's texture, application type, longevity, scent and cost.

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.”
