Top 21 Best Deodorants of 2022

How we did the test

Our tests are independently conducted and reflect the test editor's honest and objective opinions. Selection of products and test results are in no way influenced by manufacturers, retailers or other internal or external parties.

We carried out the tests ourselves and tested all the products as they are intended to be used in reality. In our deodorant tests, both men and women tested the products on several occasions and under different conditions. The deodorants were tested both during calm activities and during sweaty exercise sessions. We also evaluated how long the deodorant worked effectively for. We tested several different types of deodorant including a spray and a cream deodorant. The parameters detailed below formed the basis of the score we gave each deodorant.

  • Counteracting sweaty odours: How well does the deodorant counteract sweaty smells? How long does it last? Can it cope with different types of sweaty activities, and how often do you need to top it up?

  • Use: How easy is the deodorant to apply? Does it feel dry or moisturising on the skin? What does the deodorant smell like?

  • Stickiness: How quickly does the deodorant dry, and how soon can you put clothes on after application? Does the deodorant leave stains or discolour your clothes?

We based our evaluation on our overall experience of using the deodorant. We then compared this to the product price to determine its value for money and allocate a score to the deodorant.

1. Kiehl's Superbly Efficient Antiperspirant & Deodorant Cream - BEST CHOICE DEODORANT 2022

A deodorant that succeeds with the difficult task of being both mild and incredibly effective.

Target group: Unisex Formula: Cream Antiperspirant: Yes

Kiehl's Since 1851 Superbly Efficient Anti-Perspirant & Deo Cream 75ml

An unscented cream deodorant that doesn’t leave any sticky residues but still keeps sweaty odours in check throughout the day? It almost sounds too good to be true. But Kiehl's Superbly Efficient Anti-Perspirant & Deodorant is quite simply fantastic. The fact that it’s also mild enough not to irritate recently shaved armpits just feels like an extra bonus after an entirely sweat-free day. The promised 24-hour protection is fulfilled – and more, because it still works the day after application if you haven’t washed it off.

This cream deodorant comes in a practical tube, which means you can use it right down to the last drop. Kiehl's Superbly Efficient Anti-Perspirant & Deodorant also dries quickly and produces no stains at all on your clothes. It leaves your armpits completely odour-free, and because it isn't scented it won't compete with your carefully chosen perfume either.

Kiehl's Superbly Efficient Anti-Perspirant & Deodorant contains orange, lemon and linseed extract, and even if it isn’t exactly a budget deodorant, it’s so good that you won’t be able to stop yourself buying it over and over again.

2. Recipe for Men Alcohol-Free Deodorant Stick - BEST MEN'S DEODORANT

Smells fantastic, is economical and effective, and despite the name suits all genders

Scent: Men’s Type: Stick

Recipe for Men Alcohol-Free Deo Stick 75ml

Regardless of gender, Recipe for Men deodorant works very well. In fact, this deodorant does such a good job that it doesn’t deserve to be discounted just because it happens to target a specific group. It’s easy to apply the right amount and the deodorant doesn’t irritate the skin in the slightest. No marks or discolouration on clothes were noticed during the test period.

The lively scent and fresh feeling last all day. Our testers built houses in the summer and worked hard in heavy industrial situations, yet despite that still smelled great at the end of the day. Recipe for Men is a bit on the pricey side, but the deodorant still feels good value for money due to the fact that it’s significantly more economical than many of its competitors. In addition to all this, the packaging is really stylish. Despite all the plus points for this deodorant, it’s really the fresh scent that makes us want to buy it again and again.

3. Clarins Gentle Care Roll-On

An incredibly effective and quick-drying deodorant which lasts all day long, even during exercise

Target group: Women Formula: Roll-on Antiperspirant: Yes

Clarins Gentle Care Deo Roll-on 50ml 1-pack

The Clarins Gentle Care Roll On deodorant is a true deo-hero! If you want a fast-drying deodorant that leaves a really dry feeling, this is the one for you. This roll on deodorant is equipped with a large rollerball that means a quick stroke to each armpit is enough to amply apply the right amount of deodorant. The drying time of the deodorant is minimal despite it managing to get your armpits really dry. This quick drying time means that there's no chance of any marks on your clothes. The fragrance of this deodorant is slightly different - it has a strong, almost clinical smell that's not the slightest bit flowery or perfume-like. However, while it may have a strong scent when you apply it, the scent dissipates very quickly and soon becomes very neutral. Even after a long and hectic day, with this long lasting deodorant your underarms will have the same neutral scent as when you set out in the morning. Not even a really sweaty exercise session in the evening is a challenge for this deodorant, as we found it to cope with these easily. This is a good deodorant if you are a woman who sweats a lot. This is clearly an incredibly effective deodorant deserving of its second-place position in our test, and one of the best deodorants for women available on the market today.

4. Giorgio Armani Acqua Di Gio Pour Homme Deo Stick

A deodorant with a soft consistency, quick drying time and a fantastic scent which lasts for ages – the best deodorant for men

Target group: Men Formula: Deostick Antiperspirant: No

Giorgio Armani Acqua Di Gio Pour Homme Deo Stick 75g

The fresh scent of Georgio Armani's deostick is without a doubt our favourite scented deodorant for men in this test. The musky tones are clear but not overpowering, allowing the deodorant to stand up on its own but also easily combine with a scent for more dressy occasions. Despite the fact that the scent is minimal, it manages to last all day alongside the fresh feeling of the deodorant. You won't just have a positive experience with this deodorant because of its scent, the soft and pleasant consistency also makes it easy to apply just the right amount of the quick-drying deodorant cream in the morning. However, we found the cream did make the skin very dry, so if you have sensitive skin it could be a good idea to use a moisturising cream first.

Armani's deodorant has no problems with a quiet day in the office, hectic meetings or a gym session. It copes well with exercise sessions even if they are early in the day. However, sweaty activities in the evening are a bit tougher on the deodorant if you haven't topped it up during the day. Despite this shortfall, the deodorant is fairly non staining as we found no patches or discolouration on our clothes either during normal everyday use or during sweatier exertions. While we can’t say this is a completely anti sweat deodorant, it is deserving of its position as one of top deodorants in our test.

5. Biotherm Pure Invisible Roll-On

A fantastically sweat-suppressing deodorant which is gentle on the skin and lasts throughout your whole day's activities

Target group: Women/Men Formula: Roll-on Antiperspirant: Yes

Biotherm Deo Pure Invisible Roll-on 75ml 1-pack

If you're late for work and all sweaty, the Biotherm roll-on is your saviour – use it and you won't need to worry about smelling bad all day. Nor will a sweaty conditioning session in the gym pose this deodorant any problems. Aluminium deodorants such as the Biotherm Pure Invisible use aluminium salts as an antiperspirant to counteract or prevent sweating. It promises to last for 48 hours; while this might not be completely accurate, it's also not far from the truth.

Since it is free from alcohol, this is a great deodorant for sensitive skin or for those with sensitive armpits. It really is extra gentle – leaving your skin feeling both soothed and moisturised after you’ve applied it. The rollerball is large and follows the shape of your underarm well. With just one stroke you can easily spread the right amount of deodorant over your skin, which then dries relatively quickly and leaves neither white marks nor yellow patches on your clothes. Since the scent is mild although slightly soapy, it may be too flowery for some. However, the scent is quickly neutralised, meaning that it works well if you want to combine it with other scented products such as body mist or perfume. The scent is neither typically masculine nor feminine, so it's perfect for either sex. Because of its neutral scent, this unisex deodorant is also suitable for people of all ages.

6. Rexona Maximum Protection Clean Scent Deodorant

Effective deodorant for a good price that you can buy almost everywhere

Target group: Women (but this scent works just as well for men) Formula: Cream Antiperspirant: Yes

Rexona Maximum Protection Clean Scent Deo Stick 45ml

A deodorant with a mild scent that, even if the deodorant is marketed for women, works just as well on men. Despite its discreet and fresh scent, this is a very effective deodorant that keeps you free of sweaty odours and moisture under your arms for up to 48 hours.

For the best results, you should apply Rexona Maximum Protection Deodorant before going to bed, and it will then be most effective the next day even if you take a morning shower. But you don’t absolutely have to make it a part of your evening ritual – because it still works really well even if you apply it during the morning rush. Even after an intensive training session, this deodorant still works as though nothing had happened (even if you're so tired you just can't take another step).

Because this is a cream deodorant, it’s a good idea to wait for a couple of minutes after application before you put on a dark sweater, but once it’s dry it doesn’t stain your clothes.

One of the major advantages is also that Maximum Protection is available almost everywhere, and you don’t have to visit a department store’s perfume section.

7. Hugo Boss Hugo Deo Stick

A non-sticky, balanced scent and dry stick format deodorant

Target group: Men Formula: Deo stick Antiperspirant: No

HUGO BOSS Hugo Man Deo Stick 75ml 1-pack

Hugo Boss is one of the most classic scent brands for men. There's a reason behind this popularity - the Hugo Boss Deo Stick smells really good. It's neither too strong nor too weak; it’s quite simply perfect. This means that it's great for everyday use in the office but also at parties, since you can easily combine the deodorant with other perfumes. While its gorgeous scent is acceptable at odour blocking, it isn't an exceptionally good deodorant at this task. So while on a normal day this won’t be a problem, a sweaty gym session or breaking a sweat running for the train provides a bigger challenge for this deodorant.

The deodorant is easy to apply. While the stick is quite hard and dry in comparison with many other similar deodorants, this makes it easier to apply the right amount without it feeling sticky. However, it can feel a bit rough on sensitive skin and the deodorant isn’t optimal if you have a lot of hair under your arms. In these situations a softer stick would work better. Despite this, the quick drying time and the fact that Hugo Deo Stick doesn't leave any marks even during exercise, made this a popular deodorant in our test.

8. Biotherm Homme Day Control Roll-On

A gentle deodorant with a perfect consistency and quick drying time that effectively counteracts sweat

Target group Men Formula Roll-on Antiperspirant Yes

Biotherm Homme 48H Day Control Deo Roll-on 75ml 1-pack

The large rollerball in this Biotherm roll-on makes the deodorant simple to apply, while the soft cream of the deodorant has both a perfect consistency and a short drying time. This means that it is quickly absorbed by the skin, keeping you dry while letting your skin feeling soothed and moisturised. This dry feeling lasts all day without any problems, through both calmer activities and sweaty cross-fit sessions. The masculine scent of this men’s roll on deodorant is unfortunately reminiscent of a cheap aftershave. However, this scent is very minimal and is even more neutral after application, allowing the deodorant to be used together with another scented product. We feel that Biotherm could just as easily have skipped the scent altogether and simply made the product a really good antiperspirant. It is non staining so won’t cause any discolouration to your clothes, and due to the quick drying time you can also get dressed immediately after using the deodorant.

9. Löwengrip Count on Me Deodorant

Effective deodorant with a good scent, but unnecessarily runny

Target group: Women Formula: Roll-on Antiperspirant: Yes

Löwengrip Count On Me Deo 50ml

Löwengrip Count on Me Deodorant is a really effective deodorant that smells nice and doesn’t leave your underarms sticky – a common problem with many of its competitors.

This is a deodorant that lasts throughout your entire working day and even at the gym. The only disadvantage is actually that it’s a bit runny and takes a while to dry after application. In other words, this isn’t a deodorant that’s ideal for applying if you’re in a hurry. But on the other hand, perhaps those few minutes it takes to dry won’t actually make you all that late. Because the deodorant is so runny, however, you have to be careful that you don’t apply too much.

If you ignore the slightly liquid formula, this is a really good deodorant that does exactly what it promises and also looks nice on the bathroom shelf.

10. Nuxe Body Long-lasting Deodorant

A pleasantly scented and gentle deodorant that leaves no marks

Target group: Women Formula: Roll-on Antiperspirant: Yes

Nuxe Body Long-Lasting Deo Roll-on 50ml

The NuxeBody is a deodorant with an antiperspirant effect provided by alum and silver contents, which is effectively for counteracting sweat and odour. While a calm day at the office poses the deodorant no problems, it doesn't entirely keep sweaty smells at bay during a tough spinning session. The scent is pleasant but mild, with a hint of sweet vanilla. This means that it works well if you want to use it together with a more scented body lotion or perfume. The rollerball is small and you will need to use several strokes in order to cover your armpit. The consistency is also quite runny, meaning you can easily end up applying too much. It also means that it can take a long time for the deodorant to dry, but when it is dry it doesn't leave any marks on your clothes. The deodorant is very gentle on the sensitive skin, which will feel both moisturised and soothed after application.

11. Schmidt's Charcoal & Magnesium Deo Stick

Difficult to apply but effective deodorant without aluminium salts

Scent: Unisex Type: Stick

Schmidt's Charcoal + Magnesium Deo Stick 75g

Anyone who appreciates natural ingredients will definitely like Schmidt's Charcoal & Magnesium Deo Stick, and if you’re also looking for a deodorant that doesn’t contain any aluminium salts, this is an interesting product.

The base consists of shea butter and coconut oil, which means it’s completely different from other products in our test. It’s applied with a stick and the butter-like consistency needs to be held against the skin for a little while to warm up. If you do it right, it feels soft and smooth against your skin, but if you instead try to pull the dry stick across your skin, it will just feel tight and you won’t get any product.

Schmidt's Charcoal & Magnesium Deo Stick is unisex, but anyone sensitive to strong scents might find that it smells unexpectedly sharp. The ingredients include bicarbonate, which neutralises the odour of sweat but is a product some people can be sensitive to. If your skin feels irritated after use, it may be the bicarbonate that’s the cause.

That aside, the effect is surprisingly good. But there’s a significant downside – it turns back into small creamy rolls in your armpits after a couple of hours, which means that towards the end of the day you don’t feel particularly fresh, even if you still smell good. This probably happens if you apply too much, so you may require a little practice at first to get the dosage right.

If you aren’t sensitive to strong scents and you get the hang of by applying the right amount, Schmidt's Charcoal & Magnesium Deo Stick is a very effective and pleasant deodorant.

12. Weleda Citrus Deo Spray

A fresh, lemon-scented deodorant which can easily be sprayed from a hygienic bottle

Target group: Women Formula: Spray Antiperspirant: No

Weleda Citrus Deo Spray 100ml

Weleda's vegan deodorant contains alcohol to kill the bacteria under your armpits and it has fresh lemon scent that is intended to conceal the smell of sweat. Despite the fact that it doesn't contain any antiperspirant, it manages to keep sweaty smells away even during a long day in the office. However, the deodorant has problems coping with the challenge of sweaty activities like a gym session after work. Because the deodorant is applied with a spray, it takes a little while to dry. Despite this the spray has a good spread, meaning that only one press is enough for an even application across the entire armpit. In terms of appearance, the packaging for this deodorant stood out the most in our test. The deodorant comes in a small, oblong yellowish glass bottle, which is easy to store in your bag. The spray design also gets plus points as it feels more hygienic to spray something on your underarms than to apply the same rollerball day after day.

13. Calvin Klein CK One Deostick

A gentle deodorant with a soft, pleasant consistency that doesn't leave any marks

Target group: Unisex Formula: Deostick Antiperspirant: No

Calvin Klein CK One Deo Stick 75ml 1-pack

The idea at the core of Calvin Klein's CK One is that its scent is aimed at both men and women. While it is relatively neutral, unfortunately it falls between both camps and fails to really work for either men or women. However, the scent proves to be more neutral once applied. The application of the deodorant is very good - the top of the deodorant initially gives a plasticky impression, but it's soft and gentle on the skin. The consistency of the deodorant is sufficiently hard allowing the right quantity of the soft, soothing cream to be easily be applied to the armpit.

Even though the deodorant gives a fresh feeling after application, it can't cope with covering sweaty smells all day, not even during calmer activities. This is particularly the case for male users, who tend to sweat more than women. However, the CK One gets major plus points for not marking your clothes even if you put them on immediately after you've applied the deodorant. It is also a surprisingly cheap deodorant given that it is made by Calvin Klein, making this a fairly affordable roll on deodorant choice.

14. Nivea Men Dry Impact Deodorant

An everyday deodorant that isn’t up to everyday challenges

Target group: Man Formula: Roll-on Antiperspirant: Yes

Nivea Men Dry Impact Deo Roll-on 50ml

Finding a deodorant that works well and is available where you buy your week’s shopping can be a challenge. Nivea Men Dry Impact is a supermarket level deodorant that gets added to many people’s shopping trolleys. But how well does it actually perform?

With a relatively classic “manly” scent, it's still discreet enough to work in combination with other scented body products. Nivea Men Dry Impact doesn't hit you over the head with an overpowering perfume. But unfortunately it isn’t effective enough to live up to its promises either.

This antiperspirant is meant to last for up to 24 hours, but it just doesn’t deliver on this point. If you have a really sedentary job, Nivea Men Dry Impact will work quite well. But if you have a physically demanding job, it just won’t get you through the day.

Despite being antiperspirant, Dry Impact doesn’t reduce sweat in any noticeable way. The fact that it also loses its scent after just a few hours means that the perfume doesn’t conceal any sweaty odours either.

But given the price and the fact that Nivea Men Dry Impact Deodorant is available in almost every supermarket, it’s perhaps not surprising that this deodorant is very popular. It’s just not a particularly effective deodorant if you’re physically active.

15. Elizabeth Arden Green Tea Deo Cream

A very soft and moisturising cream deodorant, with a mature scent

Target group: Women Formula: Cream Antiperspirant: Yes

Elizabeth Arden Green Tea Cream Deo Roll-on 40ml

The cream format of this deodorant leaves you with a fresh feeling that effectively counteracts sweaty odours. It copes with calm, peaceful days without problems, but has difficulty dealing with sweaty activities such as training sessions or running for the morning bus. You use the top of the bottle to apply the soft, moisturising deodorant to your underarms and carefully work in the cream so that it's not sticky. The deodorant’s cream format means that it feels extremely gentle on the skin to the extent that it can even be used on newly shaved armpits or by those with sensitive armpits in general. The deodorant has a prominent fragrance with a green tea notes, giving the deodorant a mature character.

The top of the deodorant is entirely plastic with a hole a few millimetres across in the centre. The idea behind this is that you twist the bottom part of the deodorant to press the cream up out of the opening. Unfortunately this works very badly – often you repeatedly twist the tube and nothing happens, then the packaging suddenly splurges out far much deodorant which ends up all over your armpit. The same thing happened to us every time we tested the deodorant, which felt like a very disruptive occurrence to our morning routine.

16. Davidoff Cool Water Man Deo Stick

Leaves no marks, dries quickly and has a fresh scent

Target group: Men Formula: Deostick Antiperspirant: No

Davidoff Cool Water Man Deo Stick 70g

Cool Water is a very apt name in describing the scent of this deodorant. Each time you apply it to your armpit it emits a masculine, fresh and cold scent leaving you with a fresh feeling and ready to take on the challenges of the day. However, the scent can be perceived as a bit too strong and slightly overpowering if you aren’t looking for a perfume. The scent manages to last for about half a day before it starts to fade and needs to be topped up with more deodorant. Unfortunately the fresh feeling also fades with the scent.

The consistency of the cream in the deodorant stick is slightly softer than those from other manufacturers, meaning you often end up applying slightly too much of the deodorant making your skin feel slightly damp. However, it dries in very quickly and leaves you with a really dry feeling under your arms. This quick drying time reduces the risk of marks, allowing the deodorant to work well even during a stressful morning routine when you need to put your clothes on immediately after applying it. The deodorant also doesn’t leave any discolouration during the day. However, we found that the deodorant may be a little bit too dry for sensitive skin.

17. Paco Rabanne 1 Million Deo Stick

A strong deodorant that conceals sweaty odours well and feels soft on the armpits without leaving and marks

Target group: Men Formula: Deostick Antiperspirant: No

Paco Rabanne 1 Million Deo Stick 75g

Despite the fact that the Paco Rabanne Deo Stick isn't an antiperspirant, it succeeds very well in keeping sweaty odours at bay throughout the day. The scent is very strong, managing to remain both during calm activities and sweatier exercise sessions. However, the scent is probably too strong if you intend to use another scented product as well or have a sensitive sense of smell. Even though we felt the scent smelt good, we also feel that the strong scent isn't suitable for all occasions. For example, it might not be appropriate for an office environment in which you might need to consider others who are sensitive to heavy scents. The scent also clings to your clothes, meaning they can still smell of it several days after use.

Despite this heavy scent, the deodorant feels gentle on your underarms after application. The consistency is slightly runny, making it easy to apply too much deodorant which then takes a long time to dry. However, when the cream has dried it doesn't leave any marks on clothes, either during everyday use or during an exercise session.

18. Versace Bright Crystal Deo Stick

A non-sticky roll-on deodorant with a good scent which is easy to apply

Target group: Women Formula: Deostick Antiperspirant: No

Versace Bright Crystal Perfumed Deo Stick 50ml

This deodorant gives off a strong but pleasant scent when applied to your underarms. Despite this strong scent, the deodorant feels smooth on your skin and doesn't irritate it. The consistency of the deodorant cream is very good, making it easy to apply just the right amount of it without getting a sticky feeling. While the deodorant does contain alcohol in order to counteract armpit bacteria from underarm sweating, it doesn’t seem to counteract sweat itself well at all. Unfortunately the strong scent isn't particularly good at concealing sweat smells either, meaning during afternoons on hectic days you'll probably want to keep your distance from both friends and colleagues. Using this deodorant for an exercise session is out of the question unless you're going for a solitary run far away from civilisation. If you normally spray on perfume and want to smell a little bit less, this could be a good alternative if you aren't very active during the day. Another alternative could be to combine the deodorant with an antiperspirant that you have applied the evening before.

19. Urtekram Eucalyptus Deo Crystal Roll-On

Ineffective deodorant that doesn’t really protect at all against odour

Scent: Unisex Type: Roll-on

Urtekram Eucalyptus Crystal Deo Roll-on 50ml

Urtekram Eucalyptus Deo Crystal Roll-On sounds great on paper. The idea of a natural eco-deodorant with mineral salts instead of aluminium to ward off the smell of sweat certainly appeals, but unfortunately it doesn’t really work at all.

The smell of sweat penetrates so quickly that you think you must have forgotten to apply the deodorant at all – if it weren’t for this deodorant's highly original scent. It’s called Eucalyptus on the packaging, but our testers didn’t agree with this at all, and eventually came to the conclusion that it smelled rather more like urine.

The scent of eucalyptus would be a nice way to camouflage the smell of sweat. But to camouflage it with the scent of pee is obviously a very bad idea. And even though it’s said that it takes some time for your armpits to adjust when you remove aluminium salts from your deodorant, it would be great to have a nice scent during the transition period. But Urtekram Eucalyptus Deo Crystal Roll-On doesn’t help with this at all. On the contrary.

Everything about Deodorant

For most people, deodorant is part of their morning routine after they have showered and are feeling clean and fresh. Deodorant helps to keep sweaty smells at bay and is equally popular with women as it is with men. For many, that little deodorant container in the bathroom cupboard is just as important as their toothbrush! While it is natural for humans to sweat, it is not the sweat itself that actually smells. The characteristic sweaty odour is caused instead by small bacteria that flourish in warm, damp environments such as very sweaty armpits.

How deodorant works

Deodorants primarily function in three ways to help keep us odour-free. The first of these is some form of added perfume to conceal the odour already caused by the bacteria. The second is a range of additives that kill the bacteria so they can't produce the substances which create bad odours. These additives are most often alcohol or triclosan but can also be some form of metal compound, which doesn't kill the bacteria but helps to slow down bacterial growth. The third and last characteristic of some deodorants is that they reduce sweat. These are called antiperspirants and they use substances to block pores around the sweat ducts or cause them to contract. The most common substance that works as an antiperspirant is aluminium. Aluminium deodorants have aluminium salts which act as an antiperspirant and counteracts excessive sweating by blocking the sweat ducts. This type of deodorant can also be applied in the evening before you go to bed. An antiperspirant normally lasts for at least 24 hours, so if the deodorant is applied in the evening it has time to work properly before it's time for the following day's exertions. You can then top this up by using a deodorant in the morning which produces a pleasant scent using perfume.

For a long-time sprays were the most common type of deodorant, but there are now a range of alternatives such as roll-ons, creams or deosticks. The type that you choose depends on what you're used to and what type of deodorant you prefer. The most hygienic choice of deodorant is a spray deodorant, because no part of the deodorant packaging touches your armpit. Antiperspirant deodorants most often come in roll-on form, while deosticks are the most common form for deodorants focused on providing a pleasant scent.
