Underarm Sweat Reduction

BOTOX® for Axillary Hyperhydrosis (excessive underarm sweating)


Many Americans have severe primary axillary hyperhidrosis, commonly known as severe underarm sweating. This severe sweating is a treatable medical condition.

We produce sweat as our body’s temperature regulator, but people with axillary hyperhydrosis have overactive sweat glands, where the sweating significantly exceeds the body’s normal requirement for cooling.

In 2004, the U.S. Food & Drug Administration (FDA) approved BOTOX® (onabotulinumtoxinA) for the treatment of severe primary axillary hyperhidrosis (excessive sweating of the underarms) in patients who weren’t able to obtain relief using antiperspirants.

BOTOX® treats the symptoms of severe underarm sweating when topical medicines do not work well enough in people 18 years and older. BOTOX® treatments temporarily block the chemical signals from the nerves that stimulate the sweat glands, resulting in reduced sweating.

Only a medical professional can diagnose severe underarm sweating that is not being effectively managed with clinical strength antiperspirants. If you’re interested in this procedure, contact AesthetiCare in Orange County, San Diego, or Riverside to schedule your consultation today.

The Procedure

The procedure consists of superficially injecting  BOTOX® directly to the underarm area. The process is quick and relatively pain free.

BOTOX®   has been shown to result in an 82-87% decrease in sweating. You will start to notice results in approximately 2 to 4 days after treatment, with the full effects usually noted within 2 weeks. The dryness typically lasts 4 to 12 months. Studies have shown that repeated treatment with BOTOX®  is safe and effective for hyperhidrosis and consistently results in meaningful, long-lasting improvements in an excessive sweating patient’s symptoms, quality of life, and daily functioning.

Although sweating is essential for temperature-control, localized body areas store only a small percentage of the body’s sweat glands. The underarms contain less than 2% of the body’s sweat glands. Therefore the temporary reduction of these sweat glands’ functioning has little to do with body thermoregulation, allowing BOTOX® to be a great treatment option for those suffering from this condition.
