Why is treating hyperhidrosis important?

When sweating is excessive it can be uncomfortable, stressful and embarrassing. It can affect someone’s self-esteem and impact everything from style choice and sporting activities through to career decisions and relationships. Excess sweating may force people to change clothes several times a day.

What causes hyperhidrosis?

While stress and high temperatures can increase perspiration, they do not cause hyperhidrosis. It remains an individual variation in the distribution of sweat glands and may be hereditary in nature.

The prevalence is similar for men and women. People may produce excessive sweat in the face from emotional stress, higher environmental temperatures, or stimulants like caffeine. However, the episodes of sweating excessively may occur without any known stimulus. Excessive sweating is the increased activity of the sweat glands in response to various stimuli that may need regulation of the body’s temperature.

Hyperhidrosis prevalence is reported to be around 2.8% of the population and perhaps underestimated due to under diagnosis.

Is there treatment for hyperhidrosis?

Muscle Relaxants or Anti-Wrinkle Injections one option. With an appropriately qualified practitioner, injectables of this kind as a safe, well established and effective treatment for Axillary Hyperhidrosis (excessive sweating in the armpits). At Pavilion Cosmetic Medicine all injectors are Doctors only.

Your treatment experience

How long this treatment has been used?

Muscle Relaxants or Anti-Wrinkle Injections have been used for hyperhidrosis since 2004.

In terms of Anti-Wrinkle injections, they were first approved in Australia for eye and face movement disorders in 1993, and used in Australia and New Zealand in therapeutic treatments for over 20 years.

How does it work?

Anti-Wrinkle or Muscle Relaxant injections, delivered in small portions by a tiny needle, will help to reduce excessive sweating. The treatment stops the nerve impulse reaching that area, inactivating the sweat glands.

Sweating is controlled by the sympathetic nervous system and the sweat glands are activated by the neurotransmitter called acetylcholine. The temporary effect of Anti-Wrinkle or Muscle Relaxant injections on acetylcholine receptors causes a reduction in sweat production.
