Excessive Sweating / Hyperhidrosis

Excessive sweating / Hyperhydrosis

Excessive sweating (also known as hyperhydrosis) affects around 1% of people, and is not simply a cosmetic issue. It can lead to social and professional embarrassment and be highly distressing. Areas that are most commonly treated are the armpits, forehead, hands and feet.

Neuromodulators have been used as an effective  medical treatment for hyperhydrosis for over 40 years, and effective treatments can lead to significant improvement in quality of life. Dysport® and Botox™ are most frequently used in our clinic in the management of hyperhydrosis, but other neuromodulators may also be used. Your doctor will discuss the options with you at your consultation.

What should I expect?

This is a bespoke treatment and appointment/times will depend on the individual treatment requirements. You must have an initial consultation with your doctor, and it is not usual practice to do the treatment during a first consultation.

Your doctor will use very fine needles for the injections and will inject a very small volume of product into the apocrine sweat glands so there is minimal discomfort. Onset of action takes between 7 to 10 days. Top-ups are usually needed anywhere between 5 and 12months (average of 7 months).

It is important to note that around 5% of people will not achieve a full response, and may only have results for a short treatment duration of time (as little as 4 weeks).

Avoid the following after a treatment:

  • Use of occlusive anti-perspirant deodorants for 24 hours before and after a treatment
  • Anti-inflammatory painkillers
  • Smoking and drinking alcohol

What are the possible side-effects?

You may experience some bumps or redness in the area of the injections that tend to settle very quickly, and some discomfort and small bruises around the injection sites which can take a few days to fade. Taking arnica or eating pineapple has been shown in clinical studies to reduce the duration of the bruising.

Is this treatment safe for everyone?

You should not have this treatment if you are pregnant or breastfeeding, if you have myasthenia gravis or if you have an allergic reaction to any of the products used during the treatment. Your doctor will discuss any additional concerns with you.

Neuromodulator injections can also be used in the management of:

  • Migraines
  • Nerve pain
  • Clenching of the jaw
  • Slimming of the face in someone with pronounced jaw muscles
  • Acne on the face and chest
  • Facial rejuvenation
