Underarm Sweat Reduction Treatment: 9 Key Factors to Consider

Excessive underarm sweating, or axillary hyperhidrosis, can cause distress to individuals experiencing it. This impacts both self-esteem and daily activities.

The good news is that treatment options are available to help manage this problem effectively. But how do you choose which treatment you should undergo? We’ll provide you with nine key factors you should consider when exploring the best hyperhidrosis treatment for your underarm that best suits your needs and lifestyle.

What is Excessive Sweating?

Excessive sweating, medically known as hyperhidrosis, is the abnormal increase in sweating. You may notice this as beyond what is necessary for sweating to regulate body temperature. This condition can affect areas of the body such as the hands, feet, underarms, and face.

Primary hyperhidrosis occurs with no evident medical cause, while secondary hyperhidrosis results from other medical conditions like infections, anxiety, or hormonal imbalances.

Individuals with hyperhidrosis may experience significant discomfort and social embarrassment, impacting their daily lives and emotional well-being. However, this situation can be improved with a hyperhidrosis treatment.

What is Underarm Sweat Reduction Treatment?

Underarm sweat reduction treatment is a procedure to alleviate hyperhidrosis symptoms or treat excessive sweating. We all know how severe underarm sweating can be uncomfortable and socially distressing, and one method that can be used in treating excessive sweating is the use of underarm injections.

Underarm sweat reduction treatment blocks the release of the nerve signals in the nervous system that produce sweat and causes excessive sweating. For individuals suffering from hyperhidrosis, it inhibits the activity of the overactive sweat glands by blocking the nerve signals that trigger sweat production. As such, the treatment helps to treat excessive sweating and control sweating.

The neurotoxin injection treatment significantly reduces sweat in the treated area, providing relief from the discomfort and social challenges associated with excessive underarm sweating.

Reduced Sweating and Its Impact on Confidence

Underarm sweat reduction treatments control sweating produced in the underarm area. This reduction in sweating alleviates the anxiety associated with damp clothing, enabling people to engage more freely in social, professional, and personal activities without embarrassment.

Minimised Body Odor and Freedom from Sweat Stains

Since sweat is a primary factor in the development of odour, reducing its production naturally leads to a less unpleasant smell. The treatment also helps in preventing sweat stains on clothing, ensuring that clothes remain fresh and clean throughout the day. Underarm injections are a much more effective treatment in preventing sweat and odour compared to topical antiperspirants.

Non-Invasive Procedure with Minimal Recovery Time

The underarm sweat reduction treatment does not require surgical intervention, which makes it straightforward with minimal recovery time. Most patients can return to their routines almost right after treatment.

Long-Lasting Results

The effects of the treatment can last for at least 4-6 months, with some patients saying that their effects last longer than this, providing sustained relief from excessive sweating for a long time.

Is Excessive Sweating Treatment Right for You?

For those who experience excessive sweating and are considering treatment options, these treatments can significantly reduce sweating and also address other issues like infections, eczema or body odour.

While treatment can help manage excessive sweating, maintaining a good hygiene routine is still essential. Consulting with a healthcare professional can help determine if you are a suitable candidate for these treatments depending on your symptoms and overall health condition.

How Does the Treatment Work?

The treatment temporarily blocks the nerves that stimulate the sweat glands, reducing their activity. As a result, sweat production in the treated area diminishes, providing relief from excessive sweating.

What to Expect During Treatment

During the first consultation, the doctor will assess your condition and discuss your medical history to determine if you are a suitable candidate for the underarm sweat reduction treatment. This will ensure that the chosen treatment aligns with your specific needs and health status. The practitioner will evaluate the severity of your hyperhidrosis, consider any underlying health issues, and discuss your expectations and lifestyle.

The Procedure

On the day of the procedure, you can expect it to be relatively quick and straightforward. A medical professional will first cleanse the skin and apply a topical anaesthetic to minimise any discomfort. Small amounts of treatment injections are injected into multiple sites within each underarm using a fine needle, which takes around 15 minutes. This medical procedure is a quick and effective treatment.

Recovery Time and Potential Side Effects

Recovery time is minimal, allowing most individuals to resume their regular activities almost immediately. However, some patients may experience bruising, redness, or swelling at the injection sites — usually mild and temporary.

Results and Duration of Treatment​

The results of underarm sweat reduction treatments are often noticeable within a few days, with the full effects typically becoming evident after one to two weeks. Its benefits can last between four and six months on average. These all depend on the individual’s response to the treatment.

The reduction in sweating is temporary, and repeat treatments might be necessary to maintain results. Some individuals may require maintenance sessions as frequently as every three months, while others might find the results last longer than six months.

Underarm Sweat Reduction Treatment vs. Deodorant

Deodorants are primarily designed to mask or neutralise body odours caused by the bacterial breakdown of sweat. They often contain fragrances and antibacterial agents to achieve this. However, deodorants do not reduce the amount of sweat produced; they merely address the resulting smell.

On the other hand, antiperspirants, which are often confused with deodorants, aim to reduce sweat production by temporarily blocking the sweat glands. They usually contain aluminium-based compounds that form a gel-like plug within the sweat gland ducts. However, their effectiveness varies, and they may not offer sufficient relief for individuals with severe hyperhidrosis.

Underarm sweat reduction treatment might be a better option if:

  • You experience constant, excessive sweating that significantly impacts your daily life and self-esteem.

  • Over-the-counter and prescription antiperspirants have proven ineffective or cause irritation.

  • You prefer a treatment with longer-lasting results, reducing the need for daily applications.

  • You seek to avoid the potential staining of clothes often caused by antiperspirants or deodorants.


  • Effective Reduction of Sweat: Significantly decreases sweat production, providing relief for individuals with severe hyperhidrosis with just one treatment session.

  • Boosts Confidence: Helps improve self-esteem and comfort in social situations by reducing excessive sweating.

  • Improves Quality of Life: This can greatly enhance the overall quality of life by reducing sweat-related complications and discomfort.

  • Non-Surgical: Provides a non-invasive alternative to surgical treatments for hyperhidrosis.


  • Temporary Results: The treatment needs to be repeated every 4-6 months to maintain effectiveness, leading to ongoing costs and time commitment.

  • Potential Side Effects: Some may experience mild bruising, redness, or swelling at the injection sites.

  • Cost: Treatments can be expensive, especially when repeated regularly, and may not be covered by insurance.

  • Variable Effectiveness: The degree of sweat reduction can vary between individuals, and some may require more frequent sessions.

  • Not a Permanent Solution: For those seeking a permanent solution to excessive sweating, this treatment may not be suitable.

  • Need for Maintenance: Regular maintenance sessions are required to sustain the benefits, which can be inconvenient for some individuals.

  • Medical Consultations: Requires initial and follow-up medical consultations, which can add to the overall cost and time involved.

Are There Any Side Effects?

While underarm sweat reduction treatments are generally safe, it is natural to have concerns about side effects. Most side effects are mild and temporary:

  • discomfort

  • bruising

  • redness

  • slight swelling or tenderness

  • muscle weakness

Choosing a licensed and experienced medical professional, as they are trained to administer the treatments safely and effectively, ensures that any adverse effects are minimised.
