Understanding Botox for Excessive Sweating
Excessive sweating, also known as hyperhidrosis, can have a major impact on everyday life. People who suffer from it often experience constant dampness, stained clothes, or the embarrassment of shaking hands when their palms are wet. This condition goes beyond what is considered normal sweating and can happen even in cool environments or when you are not physically active.
Botox injections are an FDA-approved treatment that helps reduce excessive sweating by blocking the chemical signals that activate sweat glands. Once these signals are interrupted, the sweat glands slow down production in the treated areas.
At Castle Dermatology, patients often choose Botox to manage sweating that affects their hands or underarms. Both treatments are highly effective, but they work slightly differently depending on the area treated. Understanding these differences can help you decide which option is best for you.
How Botox Treats Excessive Sweating
Botox works by targeting acetylcholine, a neurotransmitter responsible for stimulating sweat glands. When injected into the skin, Botox blocks this chemical messenger, which stops the glands in that area from producing sweat. It is important to note that Botox does not prevent sweating all over your body. It only affects the treated region, so your body can still regulate temperature naturally.
This non-surgical treatment is quick and easy. Most patients notice a reduction in sweating within several days, with results lasting for months. The injections are placed carefully in the affected area using fine needles, and there is no downtime required afterward.

Botox for Sweaty Hands (Palmar Hyperhidrosis)
Procedure Overview
When treating sweaty hands, your dermatologist will inject Botox across the palms in a grid-like pattern. This ensures that the medication is evenly distributed. The procedure usually takes about 20 to 30 minutes. Because the palms are sensitive, numbing creams or nerve blocks are often used to minimize discomfort and make the treatment more tolerable.
Effectiveness and Duration
Botox for the hands can reduce sweating by 80 to 90 percent for most patients. Many people notice results within a few days, and dryness typically lasts about four to six months. With regular treatments, the effects may last longer as the sweat glands become less active over time.
Common Side Effects or Considerations
Some patients may experience mild soreness, bruising, or tingling for a few days after treatment. Temporary weakness in grip strength is possible, but it usually goes away within a short period. The hands may also feel a little stiff as they adjust to being dry.
Ideal Candidates
The ideal candidates for Botox for sweaty hands are those whose sweating interferes with their day-to-day activities. If you struggle to shake hands confidently, write, use your phone, or handle paper, this treatment can help. It is also a good option for those who have tried prescription-strength antiperspirants without success.
Botox for Underarm Sweating (Axillary Hyperhidrosis)
Botox for underarm sweating involves small injections placed just beneath the skin of the underarms. The treatment is simple and quick, usually lasting only 15 to 20 minutes. Because the underarm area is less sensitive than the palms, most patients do not need numbing. A grid pattern may be used to mark injection points for even coverage.
Effectiveness and Duration
This treatment can reduce sweating by up to 85 percent and typically lasts six to nine months. Many patients find that the results last even longer with consistent follow-up treatments. You can expect to see improvement within the first week and full results within two weeks.
Common Side Effects or Considerations
Side effects in the underarm area are usually mild. There may be slight redness, swelling, or tenderness for a few days after treatment. Rarely, some patients notice temporary numbness or mild bruising. Botox for the underarms does not affect muscle movement or strength.
Ideal Candidates
People who struggle with underarm sweating that causes clothing stains, odor, or discomfort are excellent candidates for this procedure. If you are looking for a low-maintenance and long-lasting solution that gives you confidence in any situation, Botox for axillary hyperhidrosis can make a big difference.
Comparing the Two Treatments
| Category | Sweaty Hands (Palmar) | Underarms (Axillary) |
|---|---|---|
| Procedure Time | About 30 minutes | About 20 minutes |
| Discomfort Level | Moderate, usually requires numbing | Mild |
| Duration of Results | 4 to 6 months | 6 to 9 months |
| Common Side Effects | Temporary weakness, soreness, tingling | Mild tenderness, redness |
| Ideal Candidate | Those whose hands sweat so much it interferes with work or social life | Those with odor, staining, or social discomfort |
| Cost Range | Slightly higher due to more injection points | Lower overall cost |
While both treatments are safe and effective, they differ in comfort, longevity, and cost. Botox for sweaty hands may require numbing and a higher number of injections, but it offers a significant improvement in quality of life. Botox for underarms is a faster and simpler option that often provides longer-lasting dryness.
Safety and Professional Care
It is essential to get Botox treatments for hyperhidrosis from a board-certified dermatologist or experienced medical provider. Expertise and precision are key to achieving the best results and avoiding complications. At Castle Dermatology, Botox for sweating is performed by skilled specialists who tailor each treatment to the patient’s needs and comfort level.
Patients should avoid receiving Botox at spas or non-medical facilities where safety standards are not guaranteed. Follow-up appointments are also important to assess the results and determine when maintenance treatments are needed.
Lifestyle Benefits After Botox Treatment
After receiving Botox for sweating, patients often describe a new sense of relief and confidence. Tasks that once caused anxiety, like shaking hands or speaking in public, become much easier. Those who work in environments where hand dryness is important, such as healthcare or business, notice an immediate improvement in comfort and performance.
For underarm treatments, the benefits extend to everyday life. You can wear light-colored shirts without worrying about sweat marks, enjoy social events without odor concerns, and feel confident throughout the day. Many people find that this improvement in comfort also helps reduce stress and boosts self-esteem.

When to Consider Other Options
Although Botox is very effective, it may not be the right solution for everyone. Patients with very severe or treatment-resistant hyperhidrosis might need additional options. Prescription wipes like Qbrexza, which contain glycopyrronium, can help with mild to moderate sweating. Iontophoresis, a therapy that uses a low electrical current, can be beneficial for hand and foot sweating.
For long-term underarm results, miraDry is another option that permanently reduces sweat glands using controlled heat energy. In extreme cases, surgical procedures like sympathectomy may be considered, but they are only recommended when other treatments fail.
Conclusion: Finding the Right Treatment for You
Both Botox for sweaty hands and Botox for underarms are proven, effective treatments for managing hyperhidrosis. Each has its advantages, from the duration of results to comfort during the procedure. Choosing between them depends on your main concerns, lifestyle, and how much sweating impacts your daily activities.
If you struggle with clammy palms that make social or professional interactions difficult, Botox for palmar hyperhidrosis may be ideal. If underarm sweat and odor are your main worries, Botox for axillary hyperhidrosis provides longer-lasting dryness and freedom from constant antiperspirant use.
