Welcome to our St. Louis dermatology guide on Botox for sweating, an effective treatment option for hyperhidrosis. At Mid-County Dermatology located at Missouri Baptist Medical Center, we understand the impact excessive sweating can have on your daily life, and we are dedicated to providing you with the most up-to-date information and solutions. In this article, we will delve into the details of Botox treatment for sweating, its effectiveness, the procedure, and its benefits.

What is hyperhidrosis?

Hyperhidrosis is a medical condition characterized by excessive sweating beyond what is necessary for regulating body temperature. It can affect various parts of the body, including the underarms, hands, feet, and face. This condition can be socially and emotionally distressing, leading to embarrassment, reduced confidence, and interference with daily activities.

What is Botox?

Botox, or botulinum toxin, is commonly known for its cosmetic use in reducing facial wrinkles. However, it has also proven to be highly effective in treating hyperhidrosis. Botox works by blocking the signals that stimulate sweat glands, thus temporarily preventing excessive sweating in the treated areas.

Can Botox help with underarm sweating?

Botox, known for its ability to smooth wrinkles, is also effective in reducing sweat production in the underarm area. It can decrease underarm moisture by 82% to 87%, providing dryness that typically lasts between three to 12 months.

In addition to reducing sweat, Botox also helps diminish body odor. The unpleasant smell associated with sweaty armpits is caused by bacteria thriving in warm, moist environments. By eliminating moisture, Botox eliminates odor as well.

However, even with underarm Botox, it's important to note that using deodorant or antiperspirant may still be necessary. The goal of Botox injections is to reduce excessive sweating to a normal or slightly reduced level. Some individuals may still experience mild sweating and may find the use of deodorant or antiperspirant beneficial. Results may vary from person to person.

Botox is FDA-approved for treating excessive underarm sweating (hyperhidrosis), and it is also used by doctors to address abnormal sweating in other areas of the body.

Please note that treating certain areas with Botox, such as the hands, feet, under the breasts, head, or face, maybe more painful and carry a higher risk of side effects.

How does Botox work?

Botox works by temporarily blocking the signals that trigger sweat production, specifically targeting the chemicals involved. Importantly, it doesn't affect the sense of touch or sensation in the underarm area.

When it comes to Botox treatment for underarm sweating, you can expect a single visit to your healthcare provider. The procedure typically includes 25 injections per armpit, administered just beneath the surface of the skin using a very small needle.

According to Dr. Feigenbaum, many individuals barely feel the injections. For those who do, the sensation is described as more uncomfortable than truly painful, comparable to a quick snap of a rubber band.

Within approximately three to four days, you should start noticing a reduction in sweating. The full effectiveness of combating moisture typically becomes evident after around two weeks.

The Procedure

  1. Initial Consultation: Before undergoing Botox treatment for sweating, it is important to consult with one of our dermatologists. They will evaluate your specific condition, and medical history, and determine if you are a suitable candidate for the procedure.

  2. Preparation: On the day of the procedure, the treatment area will be cleaned, and a local topical anesthetic may be applied to minimize any discomfort.

  3. Injection Process: Using a fine needle, small amounts of Botox are injected into the targeted areas. The number of injections required depends on the severity and extent of sweating.

  4. Duration: The entire procedure usually takes around 10 minutes, and you can resume your normal activities immediately afterward.

What are the benefits of Botox for sweating?

Botox treatment offers several benefits for individuals with hyperhidrosis:

  1. Effective Sweat Reduction: Botox injections have shown remarkable success in reducing sweating in the treated areas, providing relief for several months.

  2. Non-Invasive: Unlike surgical options, Botox treatment for sweating is non-invasive, requiring no incisions or extensive recovery periods.

  3. Minimal Side Effects: Side effects are typically mild and temporary, including redness, swelling, or bruising at the injection sites.

  4. Improved Quality of Life: By reducing excessive sweating, Botox can enhance your confidence, minimize social anxiety, and allow you to comfortably engage in daily activities.

Post-Treatment Care and Maintenance

Following Botox treatment, it is essential to follow your dermatologist's instructions for optimal results:

  1. Avoid Touching or Rubbing: Refrain from touching or rubbing the treated areas for at least 24 hours after the procedure to prevent the spread of the toxin.

  2. Refrain from Strenuous Exercise: For the first 24 hours, avoid rigorous physical activity to allow the Botox to settle into the intended areas.

  3. Follow-up Appointments: Regular follow-up appointments may be recommended to assess the results and determine if further treatment is necessary.

How much does Botox for underarm sweating cost?

The pricing of Botox varies based on the number of units required, but generally, the cost for both underarms is around $1,000. It's worth noting that insurance approval for this treatment is possible in certain cases, although not guaranteed for every patient with every insurance plan.

For individuals experiencing excessive sweating, Botox injections offer significant benefits. After the treatment, you can freely raise your arms without concern, and there's no longer a need for multiple shirt changes throughout the day. Say goodbye to the need for additional layers to hide sweat marks.

The outcome? You can confidently go about your day, feeling cool, comfortable, and self-assured.
