Excessive Sweating Treatment

Also known as ‘hyperhidrosis’, excessive sweating is a surprisingly common problem yet it is undertreated because of lack of awareness and its embarrassing nature. Clients having excessive sweating treatment often report life-changing results.

Axillary hyperhidrosis is excessive sweating that occurs in the underarm region. Hyperhidrosis is a condition that can affect many different body parts including the underarms. When a person has hyperhidrosis, they tend to perspire at abnormal rates. The sweating occurs usually without any external factors such as temperature or exercise.

People who have abnormal sweating patterns often suffer side effects from many social and physical problems. Socially, axillary hyperhidrosis may cause smells or stains on clothing, as well as psychological trauma for the sufferer. Anxiety may worsen axillary hyperhidrosis.

The treatment (excessive sweating treatment) for axillary hyperhidrosis involves small injections directly into the underarm area. Although some 15-20 injections are typically given in each treatment, with proper anesthesia the treatment is virtually painless.

How does excessive sweating treatment work?
Excessive sweating treatment works by blocking the release of certain chemicals that cause muscle contractions that also block the contractions and stimulation of the sweat glands.  In persons with axillary hyperhidrosis, the blockage of the overactive sweat glands produces a cessation of excessive perspiration. These injections usually take a couple of days to start working, but once they do the sweating is dramatically reduced.

Axillary hyperhidrosis stops for 8-13 months after the injections.  Another visit to your doctor and more injections will help stop the sweating once it begins again.

Frequently Asked Questions

There are 2 main types of hyperhidrosis:

  • Focal hyperhidrosis is the more common type (millions of people suffer with this) involving excessive sweating on the feet, hands, armpits and occasionally the face.
  • Generalised hyperhidrosis is less common.

Using a very fine needle, your doctor will inject a small amount (1-2mls per armpit) of solution under each arm. Sometimes a dye is used to show up the areas where sweating is greatest and where the injections should be placed.


The needles used are very fine so most people experience only mild discomfort. It is uncommon for pain relief to be required. A local anesthetic may be used when treating the palms however as they are much more sensitive: this usually wears off in less than an hour.

Excessive sweating treatment time is approximately 30 minutes. You can then go back to normal activities.

You should notice some change for the better within a week of your treatment. Different people have different responses to treatment. In a clinical trial, sweat production was reduced by 83% one week after treatment.

Usually just one session is required. All clients are invited to return for a follow-up appointment 2 weeks after their treatment. Very occasionally a ‘touch-up’ treatment is required: you will not be charged for this.

Usually between 6-8 months. As soon as you notice a return to excessive sweating you can come back to us for more treatment.

The effects of the treatment are completely reversible. If you decide not to have any further treatment, there will be no lasting change in the areas treated. Sweating will gradually return to the level it was before you started treatment.

Side-effects are rare, but a small number of clients experience an increase in sweating in another part of the body. This can also be controlled. Since the injection is made only into the skin, the effects of the treatment will be limited to the nerves supplying the sweat glands.
