Secret Clinical Strength’s Invisible Solid Deodorant smells fresh and maintains underarm dryness for 24 hours
A good invisible antiperspirant or deodorant can make or break your day. It’s the difference between feeling uncomfortable and selfconcious all day, or comfortable and confident. We expect them to effectively block our sweat, leave us smelling great, and ensure our clothes aren’t covered in white stains. But not all options on the market check all those boxes. So, which ones do?
According to dermatologists, the best deodorants contain aluminum. Claire Wolinsky, MD, is a board-certified dermatologist in New York City. She says, “There’s a lot of fear around the ingredient of aluminum. From my research, it seems that aluminum has been correlated to being a dangerous ingredient because of two things that were found: Alzheimer’s patients had an increase in aluminum in the brain. And number two: that we found breast cancers predominantly in the outer upper quadrant of the breast. So people are concerned that perhaps it’s because of a link to the drainage of the lymphatics from the armpit, but for those in medicine that’s not a cause and effect.” She explains that, a lot of the time, natural deodorants “have a lot of sugar in them and people end up with yeast infections [under their arms].”
In addition to aluminum, a good deodorant will include some proven skin-loving ingredients that care for the delicate skin under your arms. This is particularly important if you’re someone with sensitive skin, someone who removes underarm hair, or someone who has existing rashes and underarm discomfort. And, when it comes to invisibility, Tiffany Libby, MD, who is a double board-certified dermatologist and Mohs surgeon, says that when you’re shopping for invisible deodorants, “Spray and gel formulations tend to dry more invisibly and without a white residue.”
It’s important to note that antiperspirants and deodorants aren’t necessarily the same thing. While antiperspirants block sweat, deodorants block odor. However, many products are a combination of both antiperspirant and deodorant ingredients and therefore do both. After hours of extensive testing in our labs, we tested both smell- and sweat-blocking capabilities of dozens of antiperspirants and deodorants. Then, we picked the best options to help you narrow down your search for what works best for you.
Best Overall: Secret Clinical Strength Invisible Solid Antiperspirant and Deodorant
Our Ratings
Efficacy 4/5 Scent 5/5 Texture 5/5 Transfer Resistance 5/5 Overall Value 5/5
Why We Like It: It’s a hardworking antiperspirant that’s PETA-certified cruelty free to boot.
It’s Worth Noting: Some may not enjoy the ball application.
This solid gel antiperspirant was a firm favorite among the Health team. Not only did it effectively minimize sweat and odor, it didn’t transfer onto our tester’s clothes at all, and even managed to win over someone who doesn’t typically enjoy roll-on deodorants.
After 30 minutes of cardio, the deodorant effectively stopped the smell of the sweat and even after 24 hours of wearing this antiperspirant, one reviewer said, “There was just no scent from my armpits. Even when showering and smelling my clothes, there was no smell at all!”
The texture of Secret Clinical Strength is silky smooth. And while it does roll on wet, it dries clear without clumping. So, just how invisible is it? Our tests showed very little or no transfer at all even after working out and moving around throughout the day.
Product Details:
- Active ingredient: Aluminum zirconium tetrachlorohydrex gly
- Additional skin care ingredients: Moisturizing ProVitamin B5 and non-drying alcohol
- Scent: Lavender
- Size: 1.6 oz.
Best Men’s: Degree Men UltraClear
Our Ratings
Efficacy 4/5 Scent 4/5 Texture 2/5 Transfer Resistance 4/5 Overall Value 5/5
Why We Like It: This is one of the most effective and best value products among our tests.
It’s Worth Noting: This product has a strong (but refreshing) fragrance that may not suit everybody.
As an antiperspirant, our tests showed that this product was effective at managing both sweat and smell and held strong even after the 24-hour mark. And, it seems to be aptly named as our tester revealed there were “no noticeable stains on clothes” and he felt “strongly protected after physical activity.”
This product comes is easy to apply and smooths over the skin easily. The formula itself is white when it glides over the skin, but our testers agreed that it didn’t transfer onto clothes and didn’t leave a sticky residue. Our tester (who hasn’t always been a fan of Degree products) said he highly recommends this product and felt fresh and comfortable, even after a jog on the treadmill.
Product Details:
- Active ingredient: Aluminum zirconium tetrachlorohydrex gly
- Additional skin care ingredients: Moisturizing stearyl alcohol
- Scent: Fresh
- Size: 2.7 oz.
Best Spray: Dove Invisible Dry Spray Antiperspirant Deodorant
Our Ratings
Efficacy 3.5/5 Scent 3.5/5 Texture 4/5 Transfer Resistance 5/5 Overall Value 4/5
Why We Like It: It has a non-irritating spray formula that applies clear.
It’s Worth Noting: The unique fragrance may be too overpowering for some.
Our testers agreed that this is a great option for those who prefer their deodorant in a spray application. The packaging claims it’s transfer-resistant for up to 100 colors and that held true during our tests. Dove Dry Spray showed up clear from the first moment of application, stayed wet on the skin for a few minutes before drying completely, and didn’t stain any black tops or sports bras afterwards.
It’s worth noting that the label says that it will keep you protected for 48 hours. However, our tests showed that with a normal working day (which included walking through the city, exercise, and riding the subway), it lasted closer to 24 hours. But we still think that makes for an excellent antiperspirant. The fragrance, though pleasant, can eventually mix with the sweat, which is off putting for some users. If this is you, take advantage of one of the other three spray options in this list.
Product Details:
- Active ingredient: Aluminum chlorohydrate
- Additional skin care ingredients: Sunflower seed oil
- Scent: Fruity and floral—pear and pineapple top notes followed by water lilies and freesias
- Size: 3.8 oz.
Best for Men’s Scent: Jack Black Pit Boss
Our Ratings
Efficacy 4/5 Scent 5/5 Texture 5/5 Transfer Resistance 4/5 Overall Value 4.5/5
Why We Like It: It’s a quality option from an independent business.
It’s Worth Noting: This antiperspirant may transfer onto darker clothing.
Do you like to start your day with a touch of luxury? Then perhaps this is the antiperspirant for you. Sitting at the $20 mark, this is one of the pricier options, but for some, it’s worth it for the fragrance and the fact that it’s produced by an independent business and is vegan and cruelty-free.
In terms of performance, the Pit Boss scored 4.4. Major points went towards the woodsy fragrance and the fact that it kept sweat odor at bay for 24 hours. However, it was noted that the product had transferred a little onto the inside of a black shirt.
Product Details:
- Active ingredient: Aluminium zirconium trichlorohydrex gly 20%
- Additional skincare ingredients: Aloe vera and moisturizing glycerin
- Scent: Pleasant “masculine” scent, think woody yet refreshing
- Size: 2.75 oz.
Best for Sensitive Skin: DERMAdoctor Total Nonscents Ultra Gentle Antiperspirant
Our Ratings
Efficacy 5/5 Scent 5/5 Texture 4/5 Transfer Resistance 5/5 Overall Value 4/5
Why We Like It: It has a minimal ingredients list and maximum performance.
It’s Worth Noting: The price may be a little high for some, but we think it’s worth it for people with very sensitive skin.
This antiperspirant is for the anyone who typically finds it hard to wear any deodorant at all. With only six ingredients and a water-based formula, this deodorant is great for anyone who suffers from things like allergies or eczema.
And while it’s designed for those with sensitive skin, this DERMAdoctor antiperspirant proved effective in our tests, meaning it could really work for anyone. Post-exercise, our tester noted that there was no smell at all and that she didn’t feel sweat under her arms—even after a stint of cardio.
It rolled on easily with a nice texture that dried clear and clump-free. And, since there was no transfer after working out and moving around, this antiperspirant is a great option for anybody with or without sensitive skin.
Product Details:
- Active ingredient: Aluminum zirconium tetrachlorohydrex glycine complex 1
- Additional skin care ingredients: Moisturizing sorbitol
- Scent: Fragrance-free
- Size: 3 oz.
Best for Dry Skin: Secret Derma+ Invisible Gel Antiperspirant & Deodorant
Why We Like It: It has a unique application that minimizes product wastage.
It’s Worth Noting: This product did not pass our 24-hour sniff test.
The added coconut oil and moisturizing ProVitamin B5 means that this product is designed to maintain skin moisture and keep sweat at bay. In terms of efficacy, this antiperspirant did a brilliant job at minimizing sweat throughout the day and didn’t transfer at all onto clothing. The drawback is that the formula feels quite wet and slimy before it dries on the skin.
Our tests showed that Secret Derma Plus is best for those who don’t sweat excessively, however. After 24 hours, our tester could smell a bit of sweat which, although not unpleasant, means that the product did not pass the all-important sniff test. However, the pleasant coconut or aloe fragrance was highly appreciated and lasted throughout most of the day.
Product Details:
- Active ingredient: Aluminum zirconium octachlorohydrex gly
- Additional skin care ingredients: Coconut oil and moisturizing ProVitamin B5
- Scent: Coconut
- Size: 2.5 oz.
Best Fragrance Free: Clinique Fragrance Free Deodorant
Our Ratings
Efficacy 4/5 Scent 5/5 Texture 5/5 Transfer Resistance 5/5 Overall Value 5/5
Why We Like It: It has a simple formula from a trusted favorite.
It’s Worth Noting: While effective, this product is not as heavy duty as the others in the list.
This antiperspirant held up to the test as there was no perceptible smell of sweat post-exercise. However, we did notice some body odor after 24 hours, so our testers agreed that it wasn’t as strong as some of the other deodorants and antiperspirants we tested. With that being said, our testers said the texture was “excellent” because it dried quickly, was clear upon application, and left no residue.
Clinique’s invisible deodorant also received top marks in the transfer-resistance category as it didn’t transfer onto any clothing throughout the test period. Overall, our reviewer said, “This is a good, lightweight product for everyday use. If I were to work out or sweat more, I would want something with more of a scent or a stronger antiperspirant.” This product is great for anyone who is prone to allergic reactions or has sensitive skin.
Product Details:
- Active ingredient: Aluminum chlorohydrate
- Additional skin care ingredients: Non-irritating, non-drying alcohols
- Scent: Fragrance-free
- Size: 2 oz.
Best Clean Formula: Art of Sport Antiperspirant Deodorant
Our Ratings
Efficacy 4/5 Scent 4/5 Texture 4/5 Transfer Resistance 5/5 Overall Value 5/5
Why We Like It: This is an entirely natural option that holds up well in comparison to its aluminum counterparts.
It’s Worth Noting: While there wasn’t any transfer, we did notice some very slight streaking on our tester’s underarm.
The Art of Sport Antiperspirant makes for a solid, natural choice as our tests showed that it kept sweat at bay throughout an exercise session and also throughout the entire 24-hour testing period. The scent is refreshing and it was still noticeable post-exercise. However, it’s worth noting that our testers found the smell faded before the end of the 24-hour period.
This product all did a great job in the transfer-resistance category, which can sometimes be a sticking point for natural formulas. Our tester said it didn’t feel sticky after application and that there was no transfer after the testing period had finished.
Product Details:
- Active ingredient: Aluminum-free arrowroot powder
- Additional skin care ingredients: Moisturizing glycerin and vitamin E
- Scent: Cool eucalyptus
- Size: 2.7 oz.
Best Cream: Biotherm Deo Pure Antiperspirant, Cream
Our Ratings
Efficacy 5/5 Scent 5/5 Texture 5/5 Transfer Resistance 5/5 Overall Value 4/5
Why We Like It: It has an easy rub-on application, meaning it can absorb better.
It’s Worth Noting: The price may hold back people who prefer a budget option.
We named Biotherma’s Antiperspirant Cream the best cream because it check all of our boxes. There was a very light, fresh scent that was backed up by 24 hours of dryness, even in hot and humid conditions.
The unique dispenser means that you can rub in as much or as little as you like. In the case of our tests, this meant that our tester could apply a smaller amount but rub it in for longer which made for better absorption. Even in hot and humid conditions, there was no transfer onto clothing at all. Given this, we think the price is justifiable if you’re someone who would benefit from using a personalized amount of deodorant, likes a cream formula, and can spend a little extra time rubbing in your deodorant every day.
Product Details:
- Active ingredient: Aluminum chlorohydrate
- Additional skin care ingredients: Non-drying alcohol and added minerals
- Scent: Soft and fresh
- Size: 2.53 oz.
Our Testing Process
The Health team tested each of the listed deodorants and antiperspirants under the guidance and expert advice of dermatologists. They include:
- Claire Wolinsky, MD, board-certified Manhattan dermatologist
- Tiffany Libby, MD, double board-certified dermatologist and Mohs surgeon at Brown Dermatology in Rhode Island
- Joshua Zeichner, MD, associate professor of dermatology and director of Cosmetic & Clinical Research in Dermatology at New York City’s Mount Sinai Hospital
We spent hours testing each product’s attributes across these four major categories: antiperspirant efficacy, ease of application, scent, and transfer resistance. Each product was put to the test over a 24-hour period.
At the beginning of the 24-hour period, our testers applied the products to clean, dry armpits and then performed 20 minutes of cardio activity in the Health lab. Since antiperspirants temporarily block the sweat glands, the reviewer expected to have minimal to no sweat post-exercise. The antiperspirant was expected to stay effective for 24 hours without the need to reapply or shower.
What to Know About Invisible Deodorant
What Ingredients to Look for in an Invisible Deodorant
Invisible deodorants, specifically, feature a formula that is designed to stay on your skin, rather than transfer onto your clothing. So, you will need something that’s quick drying, non-clumpy and finishes clear. You will also want to keep an eye out for how hard it works to stop the sweat, therefore minimizing how much it will transfer. Dr. Zeichner says, “Deodorants are aluminum free. Aluminum-based salts are necessary to block wetness. So if sweating is an issue, you should select an antiperspirant rather than a straight deodorant. However, antiperspirants also give deodorant benefits.”
Also, if you’re someone who removes their underarm hair, it pays to choose a product that includes some added soothing ingredients. Dr. Libby says to “look for moisturizing ingredients to help hydrate and nourish skin to counteract the potential for irritation.”
Deodorants contain a variety of ingredients, including silver or magnesium, which lower levels of odor causing bacteria. Some deodorants contain acid like glycolic acid which create an inhospitable environment for odor, causing bacteria to live on the skin. Meanwhile, some deodorants contain fragrances that mask odor like a perfume.
What Ingredients to Avoid When Shopping for Invisible Deodorant
As mentioned, if you want to choose a winning invisible deodorant, look out for something that dries clear and is in spray or gel form. Dr. Libby adds, “If you have sensitive skin, avoid exfoliating ingredients like alpha-hydroxy acids, or [drying] alcohol and baking soda in deodorants.” Additionally, Dr. Wolinsky says that sometimes natural deodorants aren’t necessarily better than non-aluminum based ones. She says that “natural deodorants very often have a lot of sugar in them and people end up with yeast infections.”
How Much You Can Expect to Pay for Invisible Deodorant
You can expect to pay $10 to $15 for a good quality invisible antiperspirant or deodorant. Of the ones that we tested, the average price was $15, with some coming in under $10 (especially if purchased in a multi-pack). Meanwhile, some of the more premium brands stretched towards $30 per deodorant. Ultimately, it comes down to what works for your body and your budget.
More Invisible Deodorants to Consider
While these products didn’t check all of our boxes, they may still be of interest to you.
- Perspirex Clinical Strength: This deodorant went on smoothly and didn’t transfer at all onto a black top. However, it only took a small cardio session before it started to wear off, leaving our tester with sticky armpits and some body odor. At $18 each, we thought this made the product too expensive for its performance.
- Tom’s Antiperspirant Lavender: With a mild coconut lavender scent, this deodorant slides on dry and stays clear, but our tester said it transfers onto your clothes. The packaging is also slightly misleading as it promises 48-hour coverage but, in reality, sat closer to the 24-hour mark. Since it comes in a pack of three for $21, it’s a good value deodorant—if you can train yourself to put it on after you get dressed.
- Stress Secret Response: Although it doesn’t say it on the packet, this product has a slightly floral scent similar to that of a fabric softener. It applied easily under the arm and dried clear. After 24 hours, our tester said the floral scent was still present and slightly mixed with the smell of sweat. The biggest downside to this deodorant is that there was a very obvious transfer onto a black top which is why it didn’t make the cut.
Your Questions, Answered
Is it safe to wear deodorant every day?
“Deodorants are safe to use, and the biggest potential risk is an allergy or irritation in the skin,” says Dr. Zeichner. And Dr. Libby agrees, adding, “Yes, it is safe to wear deodorant every day. I recommend applying antiperspirant deodorant in the evening at bedtime, as it helps improve conditions for the active ingredients to enter the sweat duct and work to keep you drier during the day.” Since underarm skin is particularly delicate, consult your doctor or dermatologist to determine if wearing antiperspirant or a specific deodorant is safe for you.
What are the disadvantages of deodorant?
Some deodorants could be too drying and irritate the skin, especially for people who shave or remove hair under their arms. Also, some antiperspirants may contain drying alcohols that are ethanol-based or listed as denatured alcohol, which could cause irritation.
Is it healthier not to use deodorant?
Within this context, it’s important for you to consider what healthy means to you. However, our expert dermatologists agree that it is safe to use aluminum-based antiperspirants, which effectively block sweat. Also, they say there is not enough high-quality evidence to show that aluminum salts are dangerous for daily use.
