Botox® for Hyperhidrosis

Hyperhidrosis is commonly known as excessive sweating. This is a common condition that can affect people of all backgrounds and ages. Botox® is proven to be an effective treatment for sweating in the underarms, palms and soles of the feet.

Botox® injections disable the sweat glands in the area being treated, to provide relief from excessive sweating for up to 6-8 months. Patients will notice a reduction in excess sweat which can lead to more confidence and self-assurance in their daily life. It is a safe, effective, and non-invasive treatment with no downtime.

Although hyperhidrosis cannot be prevented, it can be treated with Botox® injections by our Double Board-Certified Dermatologist.

Hyperhidrosis Treatment Overview

What is Botox® and how does it work to treat Hyperhidrosis?

Botox® is a neuromodulator made of botulinum toxin type A. Botox® is a common cosmetic treatment to soften fine lines and improve expression wrinkles on the face. However, Botox® works on wrinkles and sweat glands in the same way – by inhibiting nerve messages. Botox® blocks the neural messages sent by the overactive nerves to the sweat glands, thus preventing the sweat glands from producing sweat. The result is a drastic reduction in sweat production.

Botox® treatment for hyperhidrosis or excessive sweating is the treatment of choice for focal areas of excessive sweating. In cases of generalized sweating oral medication or surgery may be recommended.

Hyperhidrosis Treatment Details

What types of Hyperhidrosis exist and how effective is the treatment?

Primary or Focal Hyperhidrosis – Usually affects one area such as the hands, feet, or axilla (underarms). Most of the time the cause is unknown, although it is usually hereditary. Botox® treatments work in this scenario to decrease sweating in the focal area. 

Secondary – When sweating occurs because of another medical condition. It usually occurs all over the body. For this reason, it is important to have a physician evaluate your condition.

How effective is botulinum toxin type A for Hyperhidrosis?

Randomized clinical trials have shown that the effectiveness of botulinum toxin is greater than 90% after one month of treatment and remains above 80% effective at 4 months.

Hyperhidrosis Treatment Procedure

How is a Hyperhidrosis Procedure Done?

Botulinum toxin type A is directly injected into the treatment area where patients are suffering from hyperhidrosis. Microinjections are used to deposit the Botox® close to the sweat gland.

At FCP Dermatology, a vibrating device is placed on the skin being treated to ease any mild discomfort. The procedure is very well tolerated. This is a minimally invasive procedure with no downtime. Patients can return to normal activities immediately after.

Some improvement can be seen 3-4 days after the procedure. After 14 days of treatment, sweating is visibly decreased. These results can last between 6 to 8 months. When the Botox® effects have worn off, patients will need to undergo another treatment to maintain the results. 

Before the procedure – We recommend wearing a loose, short sleeve shirt to your treatment. Avoid shaving your underarms for 2-3 days prior to your procedure. Avoid taking any blood thinners such as Advil prior to your session to prevent bruising. Inform Dr. Bailey of any medication you are taking and do not stop taking any medication unless recommended by your doctor.

During the procedure – It is a quick and simple procedure performed in the clinic. Generally, 100 units will be necessary for each axilla, palm or sole microinjected into the targeted area using fine needles. 

After the procedure – It is recommended to avoid strenuous exercise, saunas and hot baths for four hours after the treatment.
