Underarm Botox Pros and Cons: What You Should Know

Table Of Contents

Botox is the golden standard for treating wrinkles, but the benefits of Botox don’t limit there. It has proven to be a great solution for hyperhidrosis, excessive sweating in underarms.Excessive sweating can be frustrating, adding body odor and discomfort every moment. Botox offers a minimally invasive solution; however, if you are considering this option, it’s essential to understand its benefits and potential drawbacks. Here’s a detailed look at the pros and cons of underarm Botox to help you make an informed decision.

How Botox Works for Underarms?

When the Botox is applied for the treatment of underarms, it can bring noticeable changes in the sweating of the body. Botox works by temporarily blocking the nerve system that stimulates sweat glands. It decreases the perspiration and thus gives a patient a normal sweating system in the body. 

The Pros of Underarm Botox

The following reasons make it a popular choice: 

  1. Effective Reduction of Sweating: Most patients report a noticeable improvement within a few days of treatment, with effects lasting up to six months.
  2. Minimally Invasive Procedure: The procedure involves a series of small injections into the underarm area. There is no need for surgery or downtime. 
  3. Quick Procedure: It is a very quick procedure that takes 10-20 minutes to complete, making it a convenient option for those with busy schedules.
  4. Improved Confidence and Comfort: Excessive sweating can impact your confidence, especially in social or professional gatherings. Reducing underarm sweating can help you feel more comfortable and at ease, whether you’re giving a presentation, attending an event, or simply going about your daily activities.
  5. No More Stains on Clothes: For many, underarm Botox means freedom from sweat stains and frequent wardrobe changes. It can help preserve your clothing and save money on dry cleaning or replacing stained items.
  6. FDA-Approved and Safe: Botox is an FDA-approved treatment for hyperhidrosis, with a long track record of safety and efficacy. When administered by a trained professional, the risks are minimal, and the results are reliable.

The Cons of Underarm Botox

No procedure comes without any disadvantages, and Botox for underarms is no exception. You can expect such cons: 

  1. Temporary Results: While effective, the results of underarm Botox are not permanent. Most people require repeat treatments every 4-6 months to maintain the desired effects. This ongoing need for injections can add up in terms of both time and cost.
  2. Cost of Treatment:  Botox for hyperhidrosis can be expensive, especially since it’s considered a cosmetic treatment in many cases and is not always covered by insurance.
  3. Potential Side Effects: While rare, some patients experience side effects such as bruising, swelling, or mild pain at the injection site. Others might notice temporary muscle weakness or compensatory sweating in other areas of the body.
  4. Requires a Trained Professional: Botox injections must be administered by a licensed and experienced practitioner. Poor technique or incorrect placement can lead to less effective results or complications.
  5. Not a Cure for Hyperhidrosis: It’s important to understand that underarm botox treats the symptoms of hyperhidrosis but does not address the root cause. Those with severe or generalized hyperhidrosis may need additional treatments or lifestyle adjustments.

Is Underarm Botox Right for You?

Underarm Botox can be a life-changing solution for those struggling with excessive sweating, but it’s not for everyone. If you’re considering this treatment, consult with a qualified dermatologist or healthcare provider to discuss your symptoms, expectations, and medical history. They can help you weigh the benefits against the potential downsides and determine whether this option aligns with your needs.

Bottom Line

In conclusion, underarm Botox is a safe and effective way to manage hyperhidrosis, offering significant benefits like reduced sweating and improved confidence. However, it’s essential to consider the temporary nature of the results, the cost, and the potential for side effects. By understanding the pros and cons, you can make an informed decision about whether underarm Botox is the right choice for you.

Kiara DeWitt, BSN, RN, CPN founded InjectCo in early 2021 while also heading up the neurosurgery + neurology unit at Cook Children’s Pediatric Hospital as lead clinical educator. After completing her Bachelor's degree at Texas Christian University, Kiara realized just how much the aesthetic medicine industry was missing, wishing it was more focused on ethical decision-making and building relationships. Kiara’s dream was to create an atmosphere for her patients where they feel loved, empowered, and comfortable. She believes in a “lead to serve” mentality, hoping to create a more personal connection with both her patients and team alike. Kiara curated a team of 13 professionals across eight clinics, six of which are in DFW, one in Houston, and one in Austin.
Kiara loves nothing more than creating a collaborating, educational approach with her team, and thrives on personal and professional growth opportunities. She hopes that her patients feel heard and encouraged at every InjectCo visit and that they are truly excited about their personalized and well-designed aesthetic treatment plan. This love for education and safety in the industry led her to later found Texas Academy of Medical Aesthetics, an accredited training program that specializes in a 100+ hour aesthetic injector internship where students are able to train and shadow at all eight of InjectCo’s clinics.


Kiara’s patients recognize her and the entire InjectCo team as highly skilled and extremely thorough clinicians. She hopes to continue being a knowledgeable and approachable resource for clinical injectors across the country who are hoping to grow and scale their aesthetic business.
