Botox has long been recognized for its ability to reduce the appearance of facial wrinkles, but its application extends far beyond cosmetic treatments. One of the lesser-known yet highly effective uses of Botox is for treating hyperhidrosis, a condition characterized by excessive sweating. While this treatment can be applied to various areas of the body, Botox injections in the underarms are particularly popular.
Botox treatment for underarm sweating offers a temporary but significant reduction in sweat production. Many patients report a substantial improvement in quality of life, as the treatment effectively alleviates the discomfort and embarrassment associated with excessive underarm sweating. But one common question remains: how long does Botox last on underarms? In this article, we’ll explore the mechanism behind Botox’s effect on sweating, factors that influence the duration of its effects, and what you can expect during and after treatment.
What is Botox?
Before diving into the specifics of Botox treatment for underarms, it’s important to understand what Botox is and how it works.
Botox, short for Botulinum toxin, is a neurotoxin produced by the bacterium Clostridium botulinum. Although it is toxic in large amounts, small, controlled doses are safely used in medical and cosmetic treatments. Botox works by temporarily blocking the signals that travel between nerves and muscles. In the case of hyperhidrosis treatment, Botox targets the nerves responsible for activating sweat glands, thereby reducing sweating.
Botox was first approved by the U.S. Food and Drug Administration (FDA) in 2004 for the treatment of hyperhidrosis, specifically for use in the axillary region, or underarms. Since then, it has become a common treatment for people suffering from excessive sweating in this area.
Understanding Hyperhidrosis and Its Impact
Hyperhidrosis is a condition in which a person sweats more than is necessary to regulate body temperature. While sweating is a normal bodily function, hyperhidrosis can cause individuals to sweat excessively, even when the body does not require cooling.
Types of Hyperhidrosis
Primary hyperhidrosis: This type typically affects specific areas of the body, such as the underarms, palms, soles, and face. It usually has no underlying medical cause and is thought to be hereditary.
Secondary hyperhidrosis: This type is usually associated with an underlying medical condition, such as diabetes, thyroid disorders, or certain medications. Unlike primary hyperhidrosis, secondary hyperhidrosis typically affects larger areas of the body.
The Social and Emotional Toll of Hyperhidrosis
For those suffering from underarm hyperhidrosis, the condition can significantly impact daily life. Constant underarm sweat can stain clothes, lead to bad odors, and make individuals feel self-conscious in social settings. Many individuals with this condition find themselves avoiding certain fabrics or colors that make sweat more noticeable.
This is where Botox steps in as an effective treatment option, providing relief from excessive sweating and offering a confidence boost for many patients.
How Botox Works for Underarm Sweating
Botox treats underarm hyperhidrosis by targeting the eccrine glands, which are responsible for producing sweat. When Botox is injected into the underarms, it works by temporarily blocking the chemical signals from the nerves that stimulate the sweat glands. As a result, sweat production in the treated area is significantly reduced.
The Science Behind It
Botox is a neurotoxin that disrupts the process of acetylcholine release from the nerve endings. Acetylcholine is the neurotransmitter responsible for stimulating the sweat glands. By blocking its release, Botox effectively “turns off” the sweat glands in the area where it is injected. This process does not harm the sweat glands; it simply halts their activity for a period of time.
Botox Application Procedure for Underarms
Consultation: The first step is a consultation with a qualified healthcare provider. During this meeting, the provider will assess the extent of your hyperhidrosis and determine if Botox is the right treatment option for you.
Preparation: On the day of the procedure, the treatment area (underarms) will be cleansed and prepared. In some cases, a topical anesthetic or ice pack may be applied to minimize discomfort during the injections.
Injection Process: Botox injections are then administered directly into the underarms. Typically, each underarm requires multiple small injections (usually 10-15), which are strategically placed to cover the entire area.
Post-Treatment Care: After the procedure, patients can usually resume normal activities immediately. However, it’s advised to avoid strenuous exercise and hot environments for the first 24-48 hours post-treatment.
How Long Does Botox Last for Underarms?
The duration of Botox’s effects on underarm sweating can vary depending on several factors, including the individual’s physiology, the dosage administered, and how their body metabolizes the neurotoxin. On average, however, Botox injections for underarm hyperhidrosis last between 4 to 6 months. Some patients may experience longer-lasting results, while others may need retreatment sooner.
Key Factors Affecting Duration
Individual Metabolism: Every person metabolizes Botox differently. Individuals with a faster metabolic rate may find that their Botox wears off more quickly than others. In contrast, those with slower metabolisms may experience longer-lasting effects.
Dosage: The amount of Botox administered during treatment can also impact how long the effects last. A higher dosage typically provides more extended relief from sweating, though it may also increase the risk of side effects.
Severity of Hyperhidrosis: Patients with more severe hyperhidrosis may find that the effects of Botox wear off sooner, as their sweat glands may “recover” more quickly and begin producing sweat again.
Lifestyle Factors: Factors such as stress levels, exercise habits, and exposure to heat can influence how long Botox remains effective. High-stress situations and excessive sweating from exercise or heat can shorten the duration of Botox’s effects.
What to Expect Over Time
For most patients, the reduction in sweating begins within 3-7 days after receiving the Botox injections, with full results appearing by 2 weeks. During this time, patients will notice a significant decrease in underarm sweat. As the effects of Botox gradually wear off, sweat production will begin to increase again, but it will not return suddenly. Instead, it will slowly return over the course of several weeks to months.
Retreatment Recommendations
When Botox begins to wear off and sweating starts to return, most patients choose to undergo additional treatments. Botox is safe to use for long-term management of hyperhidrosis, and many individuals receive injections every 6 months to maintain sweat reduction. Your healthcare provider can help you develop a treatment schedule that suits your needs.

Benefits of Botox for Underarm Hyperhidrosis
Botox offers numerous benefits for individuals suffering from underarm hyperhidrosis. These benefits contribute to the widespread use of Botox as a treatment option for this condition.
Non-Surgical and Minimally Invasive
Unlike surgical treatments such as sweat gland removal or sympathectomy, Botox is a non-surgical, minimally invasive procedure. It involves only a series of small injections, and there is no need for general anesthesia, incisions, or significant downtime. Most patients can return to their normal activities immediately after treatment.
Quick Procedure with Minimal Discomfort
Botox injections for underarm sweating are quick, typically taking 10-30 minutes to complete. The injections are relatively painless, with many patients describing the sensation as similar to a tiny pinprick. A numbing agent or ice pack can be applied to further reduce any discomfort.
Long-Lasting Results
Although Botox’s effects are not permanent, they do last for several months. Most patients enjoy reduced sweating for 4-6 months, which is significantly longer than the results provided by antiperspirants or other topical treatments.
Improved Quality of Life
For many patients, the greatest benefit of Botox treatment for underarm sweating is the improvement in quality of life. By reducing or eliminating excessive sweat, patients can wear the clothes they want, engage in physical activities without embarrassment, and feel more confident in social and professional situations.
Potential Side Effects of Botox for Underarms
Like any medical treatment, Botox for underarm hyperhidrosis comes with potential side effects. However, serious side effects are rare, and most patients tolerate the treatment well.
Common Side Effects
Injection site reactions: Redness, swelling, or bruising at the injection site is the most common side effect. These reactions are usually mild and subside within a few days.
Temporary muscle weakness: In rare cases, patients may experience mild weakness in the muscles near the injection site.
Compensatory sweating: Some individuals may notice increased sweating in other areas of the body after receiving Botox injections in the underarms. This is known as compensatory sweating, though it is usually mild and temporary.
Rare but Serious Side Effects
Botox spread: Although rare, there is a slight risk that Botox could spread to other areas of the body, leading to unintended effects such as muscle weakness, difficulty swallowing, or breathing problems. It’s important to receive treatment from a qualified healthcare provider to minimize this risk.
Allergic reactions: Allergic reactions to Botox are uncommon but possible. Symptoms may include rash, itching, or swelling.
Alternative Treatments for Underarm Hyperhidrosis
While Botox is a popular and effective treatment for underarm hyperhidrosis, it is not the only option available. Depending on the severity of your condition and your personal preferences, your healthcare provider may suggest alternative treatments.
Topical Treatments
Prescription antiperspirants: High-strength antiperspirants containing aluminum chloride can be effective for mild to moderate hyperhidrosis. However, these products often cause skin irritation and may not be sufficient for severe cases.
Topical glycopyrrolate: This medication works by blocking the nerves that stimulate sweat glands. It is available in gel or cream form and can be applied directly to the underarms.
Oral Medications
Anticholinergics: These medications work by blocking the action of acetylcholine, the neurotransmitter responsible for activating sweat glands. However, they can cause side effects such as dry mouth, blurred vision, and urinary retention.
Surgical Options
Sympathectomy: This is a surgical procedure that involves cutting or clamping the nerves responsible for sweat production. It is typically reserved for severe cases of hyperhidrosis that do not respond to other treatments.
Sweat gland removal: In this procedure, the sweat glands in the underarms are physically removed through surgery or laser treatments. This option is permanent, but it carries the risks associated with any surgical procedure, such as infection or scarring.
Conclusion
Botox is a highly effective and long-lasting treatment option for individuals suffering from underarm hyperhidrosis. With results lasting an average of 4-6 months, it offers significant relief from excessive sweating and improves overall quality of life. While Botox is not a permanent solution, it is safe for long-term use, and many patients choose to receive repeat treatments as needed.
If you are struggling with underarm hyperhidrosis and are considering Botox, it’s essential to consult with a qualified healthcare provider to determine if this treatment is right for you. By understanding how Botox works, its potential benefits, and its limitations, you can make an informed decision about your treatment plan and enjoy a life free from the challenges of excessive underarm sweating.
