What is BOTOX® for Hyperhydrosis?

Damon Lebrun • November 16, 2017


Botox for hyperhydrosis is a treatment using Botox injections to help with excess sweating . Botox injections work by blocking the secretion of the chemical that activates sweat glands – essentially turning them off. The injections are very shallow – the medicine is injected just below the surface of the skin, where it remains. While everyone breaks down the Botox injections differently, typically you can expect three to six months of results from your injection. It is important to note that stress and exercise can cause the Botox injection to fade quicker.

Research shows it is safe to treat excessive sweating on: armpits, hands, feet and other relatively small body areas.

Botox injections have been shown to result in an 82-87% decrease in sweating under the arms. Patients typically notice results in about 2-4 days after treatment. They usually enjoy the full effects of the treatment within 2 weeks.

Although sweating is a vital part of the body’s processes as it helps with temperature control, it is safe to diminish or prevent sweating in a small, localized area because you are only impacting a small percentage of the body’s cooling system. For example, the sweat glands in the underarms are only 2% of the sweat glands in the body.

Botox injections are a very safe and effective way to combat excessive sweat problems. Take the first step by calling us today to see if you are a candidate.
