Everyone experiences sweaty armpits. For most, it occurs when working out, in hot weather, or in times of high stress. However, for others with a condition known as axillary hyperhidrosis, armpit sweating can happen anytime and anyplace. This can become disruptive and interfere with daily life. Finding treatment for hyperhidrosis is often frustrating and expensive, with many not providing relief from the condition. At The Gallery of Cosmetic Surgery, we offer a solution known to effectively treat axillary hyperhidrosis in most patients: BOTOX injections. The Gallery of Cosmetic Surgery provides the best BOTOX for axillary hyperhidrosis Bellevue and Kirkland offers.


Axillary hyperhidrosis is excessive sweating of the armpits. While armpit sweat is completely normal, people with hyperhidrosis will often stain or soak through their clothes. They also likely experience sweating at odd times such as in cold weather and at times of rest. It is estimated that around two to three percent of the population suffers from primary localized hyperhidrosis, which includes axillary hyperhidrosis.

Hyperhidrosis is generally not dangerous or life threatening. However, it can worsen skin conditions, cause rashes, interfere with daily life, worsen mental health, and hinder social interaction. Treating and managing hyperhidrosis in a non-invasive and practical manner then often becomes a priority for patients.

Primary vs. Secondary Hyperhidrosis

Axillary hyperhidrosis rarely has an identifiable cause. The condition tends to onset between the ages of thirteen and twenty. It affects men and women roughly the same. Axillary hyperhidrosis will only affect the armpits. While the rest of the body can and will still sweat, it will occur normally. Unlike axillary sweating which will likely happen nearly constantly. This is known as primary localized hyperhidrosis, or hyperhidrosis with no clear cause and localized to one area.

Another type of hyperhidrosis, known as secondary generalized hyperhidrosis, is excessive sweating due to a cause. Typically, the cause is a medical condition or medication. In these cases, sweating occurs across larger regions of the body, or over the entire body. Additionally, this hyperhidrosis responds to treatment of the condition causing it. Therefore, it is usually a temporary state. 

BOTOX treats primary localized hyperhidrosis. In theory, it could help secondary generalized hyperhidrosis, the treatment area would be too large and cost too much to be worthwhile. However, treating small areas such as the face, palms, and armpits can provide effective at decreasing excessive sweating.

Signs You May Have Hyperhidrosis

Hyperhidrosis typically requires diagnosis by a medical professional, possibly including sweat tests. If they conclude that you have primary hyperhidrosis, they may recommend BOTOX injections as one form of treatment. Some of the signs of hyperhidrosis include:

  • Excessive sweating that occurs regardless of weather, environment, or stress level
  • Sweating worsens or occurs only in one location typically the face, hands, armpits, or feet
  • Often sweat through clothing
  • Excessive sweating began during or around puberty/early adulthood
  • Frequent skin infections
  • Pale, soft, and/or peeling skin in affected areas
  • Excessive sweating happens at least one day a week
  • Changes in medications or a recent medical diagnosis (secondary)
  • Night sweats (secondary) or sweating soon after waking up (primary)

How BOTOX Treats Primary Axillary Hyperhidrosis

There are many treatments for hyperhidrosis. BOTOX is considered one of the most effective ways to decrease or stop axillary hyperhidrosis sweating. How does BOTOX work for treating hyperhidrosis? Let’s take a look at the science behind BOTOX and why it is such a compelling treatment for hyperhidrosis.

BOTOX is derived from the toxin, Botulinum toxin A, which can cause paralysis. However, when harnessed in minuscule quantities and diluted, Botulinum toxin A can block signals to the brain. This temporarily paralyzes certain functions of the targeted area. The most well known use of BOTOX is for dynamic wrinkles and fine lines. When used for this purpose, BOTOX prevents unnecessary muscle movements while maintaining normal expressions.

BOTOX for axillary hyperhidrosis works similarly. When injected, the BOTOX prevents the sweat glands and the nerves that send signals from them from firing. This greatly reduces or eliminates all sweating in the treatment area for a period of around three to nine months.

The first step to undergoing hyperhidrosis BOTOX in Bellevue is to have a consultation with one of our expert injectors. At this appointment, they will want to know about your hyperhidrosis, other relevant medical history, treatments you currently use or have tried, and your goals for treatment. They may also ask about aspects of your lifestyle such as if you smoke or how much you work out. This can affect how long results last and other aspects of treatment.

Your injector may then conduct a brief physical examination of the treatment area. This is to see any current sweating as well as ensure the area is safe for BOTOX injections. If they believe you are a good candidate, they will explain the procedure in more detail. You can then schedule your BOTOX for axillary hyperhidrosis appointment before you leave.


When you come in for your hyperhidrosis treatment, your injector will start by disinfecting the axilla with alcohol. You have the option to use numbing cream, however, the treatment is typically completely bearable without it. After these initial steps, your injector will begin treatment.

Most hyperhidrosis patients start with 100 units of BOTOX with 50 injected on each side. This is usually enough to eliminate or significantly reduce symptoms for many patients. Though, some with severe cases may require additional units. Unlike traditional BOTOX, hyperhidrosis BOTOX injections are shallower because the sweat glands are located within the skin. This means the injections are generally less painful.

The treatment takes around thirty minutes or less. Your injector can also perform other BOTOX injections or dermal fillers during the same appointment.

Aftercare & Results

Following Bellevue BOTOX for axillary hyperhidrosis treatment, patients can return to all of their normal activities. Your injector may give some instructions such as icing if necessary or avoiding exercise and alcohol for a time after injections. However, patients are free to continue working and performing their routine activities. 

Due to the shallow nature of the hyperhidrosis injections, the side effects of BOTOX, in this case, are generally limited. Pinpoint bleeding during the procedure and on the first day is normal. Some patients may experience bruising, minor swelling, or pain. These generally do not interfere with life and go away without treatment within two weeks, often within a few days.

Patients may see some reduction in sweating a few days after treatment. Although, BOTOX takes about two weeks to fully kick in. Therefore, you will likely need to wait at least two weeks to gauge the full effectiveness of your BOTOX hyperhidrosis treatment.

BOTOX is used cosmetically to address dynamic wrinkles. The same science behind what makes this possible and effective can reduce sweating in the sweat glands. Cosmetic and hyperhidrosis injection techniques vary slightly. Therefore, you must see a qualified injector like those at Seattle Plastic Surgery.


Hyperhidrosis can be embarrassing and frustrating. Without a universal cure and the benign nature of the condition, finding a long lasting and effective treatment can be frustrating. BOTOX offers a solution that lasts for months and is proven to stop or reduce sweating in most people with hyperhidrosis.

The Gallery of Cosmetic Surgery’s team of injectors is among the best in Washington State. Trained by plastic surgeons and cosmetic manufacturers, our injectors come from a variety of backgrounds that allow them to offer their unique skills and perspective to your hyperhidrosis BOTOX injections.

    Does Axillary Hyperhidrosis Go Away?

    Occasionally. Some people who develop hyperhidrosis during puberty may see their excessive sweating improve or return to normal as they get older. However, others experience the opposite, a worsening of their hyperhidrosis symptoms. Ultimately, most who have hyperhidrosis will likely continue to have the condition for the rest of their lives.

    Is BOTOX Safe For Underarm Sweating?

    Yes, BOTOX for the treatment of axillary hyperhidrosis has been FDA approved since 2004. In general, BOTOX is considered safe when in the hands of a qualified injector like at The Gallery of Cosmetic Surgery. There are few risks or complications associated with injecting BOTOX in the underarms.

    Will It Stop The Smell?

    In a way, yes. Since BOTOX prevents and stops sweating which usually causes the smell, it does often improve or stop the smell. However, once healed from the injections, it is advised that patients still wear deodorant. Some patients may still experience some sweating and not all smells may completely go away, even with cessation of sweating.

    How Long Does It Take For Underarm BOTOX To Work?

    As a general rule, BOTOX takes about two weeks to take full effect. While patients may see some effects before that, the results of treatment should not be evaluated until then. If other factors may cause the effects of BOTOX to take longer to come in, your injector will discuss this with you.

    What Is The Cost Of BOTOX For Hyperhidrosis Treatment?

    Initial hyperhidrosis treatment starts with 100 units of BOTOX priced at $1300. This cost may go up if you need more than 100 units, or treat more than one area of sweating. Your injector will go over the costs associated with your procedure during your consultation. Additionally, The Gallery of Cosmetic Surgery does work with outside financing companies to make your hyperhidrosis treatment fit your budget.
