Ultrasound Therapy for Axillary Hyperhidrosis

Axillary hyperhidrosis or excessive sweating in the armpits, can be an extremely embarrassing condition.

Axillary hyperhidrosis can get too uncomfortable for a person to accept, which leads them to look for a cure. Many treatment options are available. Some treatments are topical (applied to the area) but they can be not effective enough. If that’s the case, the doctor can then prescribe oral tablets, which are effective, but have a lot of adverse effects. Indeed, medication taken by mouth can cause some general side effects such as constipation, dry mouth and dry eyes which can be quite unpleasant.

Another treatment that can be prescribed for axillary hyperhidrosis is Botulinum toxin injections, but they are painful and they need to be periodically repeated.

If all these treatments seem unpleasant or not effective enough, fear not! Indeed, a new treatment option is available; and that’s ultrasound therapy.

Even though it’s relatively new, it’s actually very promising. It has been described as a safe, effective and potentially long term cure for axillary hyperhidrosis.

Axillary hyperhidrosis

Axillary hyperhidrosis refers to excessive sweating in the armpits. It can be either primary (without a cause) or secondary (with a known cause such as hyperthyroidism, anxiety….)

Aside from causing physical discomfort and social embarrassment, axillary hyperhidrosis can cause some more serious conditions.

For example, excessive sweating causes skin to macerate. Meaning the skin is kept moist all the time, which stimulates the growth of bacteria and fungi causing infections and bad odors.

Axillary hyperhidrosis can also be dangerous in the sense that it pushes the person suffering from it to keep applying deodorants and antiperspirants. This can negatively impact the skin causing rashes and chemical burns. Some chemicals used in antiperspirants can also be dangerous if they cumulate in the body with prolonged use.


Ultrasound is the name given to a sound wave whose frequency is higher than what humans can hear. It is basically a sound that is not audible by humans (but is by some other species such as bats). Humans cannot hear sounds with a frequency higher than 20 kilohertz, or 20,000 hertz, and that’s the frequency superior to which ultrasound devices function.

Ultrasounds have the benefit of not being invasive, and of having zero health risks.

Ultrasound Therapy for Axillary Hyperhidrosis

A new technology is available on the market, and it consists of targeting, heating and destroying sweat glands using ultrasounds.

This is achieved with the help of a new device, called MFU-V, which stands for Micro-Focused Ultrasound plus Visualization. It is able to precisely focus ultrasounds and point them at sweat glands, which heats them up to the point of destruction. The visualization component in this newly developed device allows the operator to see where they’re aiming at, so that they can avoid targeting anatomical structures such as bones or large blood vessels.

Even though this technology is relatively new, the studies conducted so far are optimistic. They have all come to the conclusion that ultrasound therapy is an emerging treatment option for axillary hyperhidrosis.

I am a blogger that used to suffer from excessive sweating of the hands and feet. Thanks to iontophoresis treatment I now live a completely normal life. A few years ago I decided to start blogging about this topic to help other people that are suffering from this condition.
