Sweating is a natural response to physical exercise, heat, or even stress. Perspiration is designed to keep our body cool –– but some of us sweat so excessively that it becomes a problem.

What you may not realize is that an abnormal amount of sweating is an actual medical condition known as hyperhidrosis. Hyperhidrosis refers both to excessive sweating all over the body, or hyperactive sweating in just one area.

If you deal with this issue, you aren’t alone. Hyperhidrosis affects around 3% of the US population –– that’s nearly ten million people. 

Areas commonly affected by hyperhidrosis include the forehead, face, underarms, feet, and the palms of the hands. These areas can become soaked in sweat even when the rest of the body isn’t. This sweating can occur even without physical exertion or overheating.

Those who suffer from hyperhidrosis may find it affecting their lives in a myriad of ways. Extreme sweating can lead to embarrassing stains on clothing and unpleasant body odor. Perspiration on the head and face can interfere with makeup application and hair styling. Sweaty palms can make carrying out everyday tasks, like shaking hands, driving or opening containers, tricky.

In the long run, all these issues can hurt your self-esteem. In fact, patients suffering from hyperhidrosis have a higher chance of dealing with depression as well as anxiety. 30 to 37.9% of patients with hyperhidrosis report their excessive sweating being a constant strain on their daily life and mental health, while 64.7 to 86% reported moderate to severe negative emotional impacts. Many also report significant impacts on everything from hobbies to their career as a result of hyperhidrosis.

Botox was FDA approved for hyperhidrosis in 2004. When injected into the sweat glands located throughout the skin, Botox disables neurotransmitters and prevents the glands to secrete sweat. As a result, patients are left sweat-free for 4 – 6 months.

Botox for excessive sweating is a quick, convenient, and effective procedure that involves limited side effects and zero downtime. Current research based on randomized controlled trials demonstrates that Botox is 80% – 90% effective in treating symptoms of hyperhidrosis in only one treatment.


Everybody sweats from time to time. Sweating is a regulatory mechanism that our bodies use to keep cool. However, hyperhidrosis refers to sweating that occurs in abnormal amounts and without an obvious cause. But why does this occur?

Extreme perspiration begins in the central nervous system, with the overstimulation of cholinergic receptors on eccrine glands. In more simple terms: hyperhidrosis occurs when nerves send signals to sweat glands more frequently than they are supposed to.

Eccrine glands, also called sweat glands, are heavily located in parts of the body that typically sweat the most –– such as the forehead, armpits, feet, and palms.

There are two major types of hyperhidrosis:

  • Primary Focal Hyperhidrosis

The first kind of hyperhidrosis is known as primary focal hyperhidrosis. This form of the condition has no clear cause, but primarily involves excessive perspiration in specific areas of the body, such as the hands, feet, head, and underarms.

The causes of primary focal hyperhidrosis are still unknown, though it is likely related to genetic factors. Overactive neural stimulation may be an inherited trait. Primary focal hyperhidrosis often begins in adolescence.

  • Secondary Generalized Hyperhidrosis

Secondary generalized hyperhidrosis occurs in more generalized area of the body, and can even bother patients while sleeping. This type of hyperhidrosis is associated with the use of certain medications, as well as systemic disorders.

The onset of secondary generalized hyperhidrosis is often in adulthood. Excessive alcohol consumption and febrile illnesses are linked to secondary generalized hyperhidrosis as well. 

  • How common is it to overproduce sweat?

Hyperhidrosis is likely more common than you think. Around 3% of the US population experiences an overproduction of sweat and overactive sweat glands.

  • Does severe axillary perspiration go away?

While all people experience underarm sweat from time to time, those who have been dealing with extreme axillary perspiration for over six months often have difficulty finding relief, even when they are not physically exerted, hot, or stressed. While drugstore deodorants may not be helpful, regular botox follow up sessions can significantly help this issue.


A popular and FDA approved treatment method for hyperhidrosis is the injection of the neuromoderating botulinum toxin type A, also known as Botox. Botox inhibits heavy perspiration by temporarily restricting the release of the neurotransmitter acetylcholine. This novel toxin breaks apart the SNAP-25 protein, which, in turn, prohibits the release of acetylcholine and the overstimulation of sweat glands. Without the sweat, or eccrine glands being overstimulated, sweat production will cease.

Once the sweat glands are shut down, the excessive sweat production is stopped, leading to a chain reaction eliminating all the uncomfortable symptoms associated with underarm sweating. Because excessive sweating occurs due to overactive sweat glands, botox is an excellent solution to mitigate the root of the problem.

Botox hyperhidrosis


Many patients prefer Botox as a hyperhidrosis treatment method due to its efficacy and longevity. In fact, in a study of 145 patients, 98% of them said they would recommend Botox injections to others for excessive sweating.

When hyperperspiration is a significant part of your life, other methods are often less effective. Topical treatments, such as antiperspirants or aluminum chloride gel, are a much more temporary and often irritating, solution. Other surgical options such as endoscopic transthoracic sympathectomy or the excision of sweat glands are invasive, expensive, and require significant downtime.

In contrast, Botox injections are a much quicker, safer, and more durable treatment method for excessive sweating. Hyperhidrosis patients who have been failed by topical antiperspirants experience a 75% improvement in their symptoms after neuromodulator procedure, and a better quality of life.

In addition, Botox injections have become socially accepted as a part of daily conversation amongst the beauty industry and social media. A large variety of platforms such as Instagram and YouTube are filled with photos and videos explaining how botox works to treat various conditions, including unusual sweating.

If it works for Chrissy Teigen, will it work for me?

Model and social media influencer Chrissy Teigen is all about being open and honest with her fans and followers and happens to be one of the many individuals suffering from excessive underarm sweating. Chrissy recently opened up about how Botox has been incredibly helpful for her to show off her full-sleeved shirts without the fear of being judged for her sweat stains and encourages her fans to normalize the condition, rather than hiding from it. If you suffer from excessive underarm sweat like Chrissy Teigen does, any type of neurotoxin may also be a solution for you.

Botox excessive sweating


Hyperhidrosis is diagnosed in patients who have been experiencing overactive perspiration for at least 6 months or more. If you are otherwise healthy, yet experience this kind of excessive sweating to the point where it interferes with your daily and professional life, you are likely a candidate for treatment via Botox injections.

When considering Botox for hyperhidrosis, it is important to have a conversation with your doctor about your condition and treatment options. If topical treatments such as antiperspirants do not provide relief from your symptoms, Botox can be an effective solution for you.


At Skinly Aesthetics, you can receive Botox injections for excessive perspiration in the palmar, plantar, and axillary areas, as well as other parts of the body. During a consultation with Dr. Schwarzburg, you can establish a personal treatment plan, identify your goals, and discuss any relevant medical history to determine if you are a candidate for hyperhidrosis botox treatment.

  • Can I get Botox to treat my sweaty hands?

Primary focal hyperhidrosis in the hands (also known as palmar hyperhidrosis) commonly acts up in response to stressful or anxiety inducing situations. This type of sweaty hand symptom can be treated by botox injections.

  • Can I get Botox for face sweat?

Yes, botox is a viable method of controlling facial perspiration. Many patients who receive botox injections for wrinkles also enjoy the added benefit of sweat reduction in the forehead. 

The procedure for treating hyperhidrosis involves infusing Botox  into the dermal layer where the sweat glands are located. This is different from the Botox technique used to combat facial wrinkles, which targets the muscle fibers. Botulinum toxin type A operates as a neuromodulator. This means that it affects neurotransmissions taking place in the peripheral nervous system, which signal your body to produce –– or overproduce –– sweat.

  • How many units of Botox are necessary to reduce sweating?

In one session, most patients need at least 100 units of Botox for significant results. When treating both armpits, hands, or feet, that means 40-50 units will be injected into each side. More severe cases of overactive sweating may require a great number of Botox units for the desired effect.

  • How does one inject Botox to paralyze the sweat glands?

Botox is injected via an ultra precise nano-needle into a superficial dermal layer using several (20 to 30) injection points. These injections are spread out in a gridlike pattern, with distances of about 1cm in between, to target excessive sweating.

  • How long is the procedure?

Prior to the procedure itself, a numbing cream is applied. The numbing cream is given 30 to 45 minutes to take effect. After this, the botox injection process only takes around 10 to 20 minutes. In total, a botox session for hyperhidrosis takes around 40 minutes to 1 hour.

  • Does botox in the armpits stop smell?

With the improvement of hyperhidrosis symptoms, you can also expect a significant reduction in unpleasant body odor. The unpleasant smell of body odor is brought about by the bacterial growth and decomposition of the constituents of sweat, including lactic acids and fatty acids, secreted from different glands. Because the overstimulation of these glands is prevented by botox, body odor will also decrease. 


Botox injections for sweat reduction can be painful, as they are often administered in highly sensitive areas of the body. The palms of your hands and soles of your feet, for example, are the site of many rich nerve endings. In addition, they often require multiple injections. To reduce discomfort, you will receive a strong topical numbing cream in anticipation of  your treatment. 


In most cases, there are no adverse effects when treating hyperhidrosis with neurotoxin injections. However, some patients have found that temporary side effects include muscle soreness or slight itching in the axillary. In a study of 145 patients, 63.4% of patients report being completely satisfied after their treatment, while the remaining 26.6% report at least partial or moderate satisfaction.


Patients commonly observe a reduction in sweating within the first week following their Botox treatment. This improvement is generally the same for those with both moderate and severe symptoms. Afterwards, you can expect relief from your symptoms for about 6 to 9 months. 


Botox injections used to treat planter perspiration (in other words, hyperhidrosis of the feet) typically last around 6 to 9 months. Some may choose to manage the symptoms of hyperhidrosis with repeated injections over the course of many months or years.


The cost of Botox injections for overactive perspiration generally depends on the severity of the issue, as well as the area being treated, as these factors influence the amount of units needed. Other external factors, such as location and the level of skill and experience of your injector, contribute to the cost of treatment.

You can expect to pay more for a highly experienced and knowledgeable board certified surgeon, for example, than a nurse. The average cost of a botox session for hyperhidrosis is around $1000 to $1500.


Yes, botox, or the injection of botulinum toxin A, is a safe, effective, and FDA approved treatment method for excessive sweating. Patients who undergo these highly advanced injections for hyperhidrosis report a significant reduction in their symptoms as well as an improved emotional, occupational, and social life as a result. Patients also prefer botox injections over other control methods for excess sweat, such as topical antiperspirants. Clinical studies demonstrate that botox for excessive sweating is 80% – 90% effective for both primary focal and secondary generalized hyperhidrosis.


Botox in the underarms is FDA approved and a reliable treatment for hyperhidrosis. When administered properly by a board certified physician, there are no safety concerns for this treatment method.

However, because of the complex anatomy, improperly performing the injection (for example, deviating 1 mm in depth, or injecting at the wrong angle) could result either in inefficacy or in some form of muscular paralysis. Before making a botox appointment to treat hyperhidrosis, talk to your doctor about any concerns you may have.


Yes, botox injections for sweat prevention are sometimes covered by insurance because hyperhidrosis is considered a medical condition.


Many people suffer from the far-reaching effects of excessive perspiration, or hyperhidrosis, in their lives. From aesthetically unpleasant effects to trouble performing daily tasks, many patients find themselves at a loss with how to cope with this condition.

Botox injections administered by a skilled, board certified cosmetic surgeon or physician are a quick, long-lasting, and safe treatment method for dealing with hyperhidrosis. This treatment method is preferred by many patients as a procedure with high efficacy and little downtime. 

Being more successful than topical antiperspirants and less invasive than surgical options, these treatments can help improve your quality of life by controlling excess sweat. Be sure to consult your doctor to see if botox injections are right for you.
