BOTOX: cost effective treatment for excessive under arm sweating

Since 1989, botulinum toxin has rapidly gained international medical and public recognition as a treatment of choice for the correction of frown lines, brow lines and crows feet. In recent years, its cosmetic application has broadened to include other facial lines, muscle tone reshaping and sculpturing of the face, and has become a very effective treatment for excessive armpit sweating (hyperhidrosis).

What Is Botulinum Toxin?
Botox ™ (produced by Allergan) or Dysport ™ (produced by Ipsen) are commercially purified forms of toxins produced by the Clostridium Botulinum bacteria. In its natural state this bacterial toxin is responsible for causing botulism (food poisoning). This occurs when a large quantity is eaten, and results in widespread temporary muscle paralysis throughout the body. It is this temporary loss of muscle action that has been, for many years (since the 1890’s), exploited for clinical advantages in numerous fields of medicine, including ophthalmology(eye speciality), neurology (nerves), musculoskeletal and since 1989 popularised for its use in the field of cosmetic medicine. 

How is it used for hyperhidrosis (excess sweating)?
Cosmetically,Botox ™ has been used to treat certain movement-generated wrinkles in the face. The muscles that cause these wrinkles are temporarily relaxed by micro injections of Botox ™, which result in the lines fading away over time. It was following the treatment of forehead lines in the 90's that we noticed that patients reported that they sweated less across the forehead area. This was not a problem to them and in fact many commented favourably that it was a bonus when working out at the gym! It was from this that the idea of treating excess under arm sweating came about.

For hyperhidrosis, the Botox is injected very superficially as multiple micro droplets into the armpit skin where it acts directly on the sweat glands. To ensure the right amount of Botox is used, a sweat test is performed immediately prior to treatment. This identifies the exact location of the overactive sweat glands and thus limits the Botox treatment to only the affected areas. This obviously means there is no over-treatment, there is no wastage and importantly it keeps the cost down to the required minimum.

Botox™ treatment for under arm sweating is an outpatient procedure done at a clinic. The treatment itself doesn’t take long, is relatively painless and you are able to resume normal daily activities immediately after treatment.

Reduction in sweating occurs very quickly, within days, and the result lasts for 6-12months. Subsequent treatments can result in more prolonged dryness.



Dr Beulink’s Personal Comments – Botulinum Toxin for Sweating

Using Botox to treat people with axillary (armpit) hyperhidrosis (hyper=excessive, hidrosis=sweating) is very effective. These are the people that have told me: “Botox has changed my life!” 
Typically, they have previously tried just about every deodorant and concoction under their arms without success. The sweat just keeps "pouring out" no matter what the temperature is. After Botox treatment, they go from needing 2 or 3 changes of shirt or blouse at work each day, to be able to leave home in the morning and return in the evening in the same top. Hiding it in black tops is no longer necessary; freedom to wear colours becomes the new norm. It is that effective!


In my experience I have found that with Botox treatments, placement is extremely important for the type and length of results.
And as every person is not “built” equal, each treatment needs to be tailored specifically to that individual’s areas of sweating, to ensure a maximum effective treatment. In this respect sweat testing every time is manditory.


I have seen extremes, where one entire armpit can be generally affected while the other is limited to just 1 or 2 discrete localised areas of hyper-activity requiring only a very small amount of Botox to fix.  After treatment, within days the sweating completely dries up.

In 1994, I found that Botox treatments to the face were often associated with an unacceptable risk of bruising, particularly around the eyes. Additionally, the treatment was a bit stingy. Soon afterwards, I produced a unique formula to minimize and often stop any bruising, and reduce the discomfort to virtually zero.
This procedure is quick, easy and almost painless (with my technique and unique formula most patients exclaim how minimally uncomfortable it is!).


Treating an area of excess sweating does not make other areas sweat more.You will not sweat more after the treatment effect has worn off. Shutting down the hyperhidrosis will not affect your tempurature regulation.

Some people worry that treating in the armpit region may leave them with weak arms. This is NOT the case, as long as this product is placed and used appropriately and sensibly. I have never had a case of weak arms or anything else bizzare. 

Botulinum toxin has over 40 years use in the field of modern medicine, and although it is a “toxin” to the body, we are using approximately 1/5000th of a lethal dose. To date, I am unaware of any long term side effects (with sensible use!).

Before any procedure can go ahead, informed consent must be given. A half hour, initial consultation and assessment with Dr Beulink is required, during which time he goes over your concerns, outlines different procedures available to you that you may benefit from, what they do, how they work, downtime, results,  costs, etc, etc.  It is essential to have this initial consultation and assessment with the doctor who is going to perform the procedure, as it is important for you to know exactly what the procedure is, products used, what results can be expected and what problems or side effects can happen. Once you are well aware of all these details, and all your questions are answered, treatment can proceed.

Botox and Dysport are Prescription Medicines containing clostridium botulinum Type A toxin complex for injection. It is used for the treatment of severe frown lines of the face. In NZ, it should be administered only by trained medical professionals. Arrange a consultation to discuss the benefits/risks of this procedure in cosmetic medicine. Cautions: people with defective neuromuscular transmission disorders, presence of infection at site of injection, glaucoma, pregnancy and lactation. Possible side effects include headaches, pain, burning or redness at injection site, local muscle weakness including drooping eyelids, lack of feeling and nausea. If you have side effects or concerns speak to a doctor. A charge may apply. Note: Botox and Dysport treatment lasts about 4 months and after this time further courses of treatment could be necessary. Arrange a consultation to discuss your own situation.
