Sweating is a natural part of life, especially in a hot and humid climate like Honolulu. But hyperhydrosis, or excessive sweating, is not. If you struggle with underarm sweat, palm sweat, or food sweat body that is severe and affects your day to day life, you are not the only one. Many people suffer from excessive sweating, also known as hyperhydrosis. Hyperhydrosis can severely impact your quality of life and leave you feeling self-conscious. Neuromodulators, such as Botox, are a highly effective treatment for hyperhydrosis that can reduce excessive sweating by over 80%. A single treatment can help keep you dry for 4-12 months.

You've probably heard of Botox, but it's just one option among several. There are multiple FDA-approved neuromodulators on the market. Two of our favorites include Botox and Jeuveau.

This guide covers hyperhydrosis, how it works, what to expect from a treatment, and the type of results you can typically expect. Whether you're considering this treatment for the first time or just looking to learn more, you're in the right place.

What is Hyperhydrosis?

Hyperhydrosis is the medical term for excessive sweating. Hyperhydrosis commonly affects areas of the body that have high levels of sweat glands including:

Underarms (Axillary hyperhidrosis)
Palms of the hands (Plamar hyperhydrosis)
Soles of the feat (Plantar hyperhydrosis)
Face and forehead (Craniofacial hyperhydrosis

For people who have primary hyperhydrosis, the excessive sweating happens without major triggers such as heat or strenuous exercise, often soaking through clothing and becoming evident which typically interferes with everyday tasks.

How Does Botox Stop Excessive Sweating?

While most people associate Botox with smoothing out wrinkles, Botox is also FDA-approved to treat severe primary axillary hyperhydrosis, also known as excessive arm sweating.

Botox works by blocks the release of acetylcholine, a chemical messenger that signals your sweat glands to turn on. By temporarily blocking this nerve signal locally, the sweat glands in the treated area are safely turned "off".

Is it safe? Yes. Treating localized areas allows for improvement in areas that cause issue, while maintaining the rest of your body's overall ability to cool itself or excrete toxins. The untreated areas of your body will continue to sweat.

Common signs you may be dealing with hyperhydrosis include:

Soaking through shirts shorty after getting dressed.
Anxiety about visible sweat marks or body odor.
Needing to change your clothes multiple times a day due to sweat marks.
Irritation of skin or discomfort due to persistent dampness from sweating.

Common Treatment Areas

Neuromodulators can treat a variety of areas for excessive sweating. Axillary treatment of the underarms remains the primary, FDA-approved area to treat. However, there are other areas providers can treat off-label.

Primary treatment areas include:

Underarms (Palmar Hyperhidrosis)
Palms of Hands
Soles of Feet (Plantar Hyperhidrosis)

Additional areas that can be treated:

The upper lip
Under the Breats (Inframammary Sweating)
Face, Scalp, and Hairline (Craniofacial Hyperhidrosis)

The right treatment plan depends on your anatomy and symptoms. An experienced provider will assess your anatomy and history, and recommend an approach tailored to your specific goals.

What to Expect During Treatment

It can be helpful to know some things you can expect during your appointment.

Before: Your appointment starts with a consultation to discuss your medical history, symptoms, and confirm Botox is the right treatment for you. Prior to treatment provider will clean and sanitize the area, and often mark the areas to treat with a small dot. Some providers offer numbing cream, but most patients find they don't need it.

During: Treatment itself is quick, typically just 10-15 minutes. Small amounts of product are injected using a ultra-fine needle into the targeted areas. Most people describe the injections as a tiny pinch and are able to tolerate the procedure well. The number of injections varies depending on which areas you're treating.

After: There is minimal downtime. You can return to most normal activities immediately. Small bumps at the injection site usually resolve within 15 minutes. It is advised to avoid strenuous excursive, hot tubs, saunas, or heavy sweating for 24 hours.

Results and Timeline

Onset: Most people start noticing changes within 3-5 days as the product begins taking effect. Full results typically become visible around 10-14 days after treatment.

Peak Results: Around the two-week mark, you'll see the full effect of your treatment. This is a good time for a follow-up appointment if you're new to neuromodulators, in case any touch-ups are needed for best result.

Duration: Results usually last patients 4-12 months. However, results can vary by person, product, and treatment area. Some metabolize the product faster than others, or require higher dosages.

Maintenance: To maintain your results, plan for treatments at regular intervals once results fade.

Aftercare Tips

Aftercare includes simple precautions after treatment help ensure the product stays where it was placed and reduce the risk of bruising or migration.

Key guidelines to follow:

Avoid touching, rubbing, or massaging treated areas for 4-6 hours
Stay upright for 4 hours after treatment
Avoid strenuous exercise for 24 hours
Avoid alcohol for 24 hours
Skip facials, saunas, or hot tubs for 24-48 hours

Most people return to their normal routine almost immediately after leaving their appointment.

May not be ideal if you:

Are pregnant or breastfeeding
Have certain neuromuscular conditions like myasthenia gravis
Have unrealistic expectations about what treatment can achieve
Are looking for permanent results

A consultation is the best way to determine if you're a good candidate for this treatment.
