Sweating, or perspiration, is a normal phenomenon in humans. The evaporation of water from the skin takes heat away from the body and so sweating is essential for temperature control.


The control of sweating is via the sympathetic nervous system. The nerve runs from the brain, down the spinal cord and then comes out and communicates with the sympathetic nerve which lies in the ‘sympathetic chain’. The sympathetic chain lies on the bone of the spinal column. This nerve then runs from the sympathetic chain to the skin where it connects to the sweat glands. The nerve controlling sweating depends upon a chemical transmitter called acetylcholine which is a molecule produced at the very ends of the nerve fibres.

Hyperhidrosis (excessive sweating) can be a troublesome problem that results in awkward social situations for those affected. It is caused by stimulation of the ecrine sweat glands by the nerve endings which are the final nerve pathways from higher centres in the brain. These nerves respond to different kinds of stress: emotional stress (intimate social situations or public speaking) or physical stress (increased body temperature from exercise or hot and humid weather). Some people are routinely troubled by excessive sweating whilst others are only bothered when they are under emotional stress, physically active or over-heated.

Excessive sweating causes

Excessive Sweating Treatment

Topical antiperspirant sticks, creams, lotions and solutions typically use aluminium chloride hexahydrate salts (Driclor, Trust) which coat the skin and prevent the sweat from exiting the pores. Current anti-cholinergic drugs and tranquilizers can cause dry mouth, blurred vision and minimally reduce sweating. Tranquilizers may minimise your anxiety over sweating, but rarely reduce the amount of perspiration.


Surgical options involve cutting the underarm skin which contains the sweat glands which may result in very visible scars and permanent skin numbness. Neuro-surgeons use a fibre-optic surgical tube inserted into the neck to cut the nerve fibres leading to the axillary sweat glands and arms (endoscopic sympathectomy).


One of the most effective ways of how to stop excessive sweating is by injecting a dilute solution of Botulinum toxin, a naturally occurring protein derived from bacteria, into the skin of the axilla (armpit). Botulinum toxin (Botox®) can prevent sweating for months by blocking the release of the neurotransmitter, i.e., acetylcholine, from the nerve endings, that causes the glands to produce sweat. Skin Deep Rejuvenation Therapies are pleased to offer clients, male and female, this very safe and effective treatment.

What happens during treatment?

The underarms are shaved (or you can arrive with shaved armpits!). After application of a anaesthetic an iodine and corn starch test will identify the affected area. Using a very fine needle tiny amounts of Botulinum toxinA protein are injected and binds to the nerve that controls sweating in the skin. The protein then works by reducing the effect of local nerves that stimulate the sweat glands. This results in the production of less sweat.


A first course usually lasts between 4 and 9 months whilst subsequent courses are more effective and last from 6 to 12 months. Heavy physical exercise should be avoided for several hours post treatment but generally clients may engage in any normal activity. Most people notice some change for the better within a week of their treatment although individual responses can vary. In clinical trials sweat production was reduced by more than 90% within two weeks of hyperhidrosis treatment.

Are there any complications?


Injections into the armpit can cause some tiny bruises which fade in a few days. Occasionally small persistent areas of sweating may need a second treatment session at 2 weeks, free of charge. There is no risk of muscle weakness, numbness or permanent change in the underarm skin. Occasionally there is a perception that sweating in other areas of the body increases, however here is no clinical evidence to support this.

Who should not have this treatment?


Individuals with a known hypersensitivity to any component of the formulation.

Patients who have generalised disorders of muscle activity (e.g. myasthenia gravis).

Patients where aminoglycoside antibiotics or spectinomycin are already being used or are likely to be used.

Patients who have bleeding disorders of any type.

Pregnant or lactating women.
