Hyperhidrosis Treatment

Hyperhidrosis, also commonly known as excessive sweating, is a condition that affects all genders.

This condition can be embarrassing and uncomfortable, with it affecting around 3% of the UK population, impacting their day-to-day lives from working to socialising.

There are two main types of hyperhidrosis: Focal hyperhidrosis and Generalised hyperhidrosis. Focial hyperhidrosis is more common, involving excessive sweating of the hands, feet and underarms. Generalised hyperhidrosis is less common and affects the whole body and is usually a result of an illness or infection.

Wrinkle injections (botulinum toxin injections) can be used to treat hyperhidrosis. Although we may think of botulinum toxin as a cosmetic treatment for wrinkles, it is a muscle relaxant that has been used by doctors in the UK for years to treat profuse sweating as well as other medical conditions.

At The Cosmetic Skin Clinic, we only use wrinkle injections to target excessive sweating in the armpits. We do not offer treatment for excessive sweating of the hands and feet due to the discomfort, downtime and potential side effects that can be associated with performing the procedure in these areas.

Hyperhidrosis is a term for excess sweating and is treated with injections of botulinum toxin. This is an FDA-approved medicine that’s a muscle relaxant.

At The Cosmetic Skin Clinic, our experts administer a series of small injections in the armpit area during the procedure.

Botulinum toxin is a naturally purified protein that blocks the signals from the nerve endings to the sweat glands in the skin. This is used in the treatment of excessive sweating. This toxin is applied through micro injections into the skin targeting the sweat glands in the area which requires treatment. This safe procedure is proven to give dramatic and life-changing results for many who suffer from this condition.

It normally takes 5-7 days for the muscle relaxant injections to work.

You may need to repeat treatment for sweating approximately every 3-4 months. Your medical practitioner will give you all the advice you need.

If you’re worried about excess sweating, it’s vital to put yourself in the safest possible hands to ensure the most effective results.

We will explain everything in detail and make you feel at ease and relaxed on the day of your treatment, knowing you’re in safe, expert and medically qualified hands.

Botulinum toxin has an excellent safety profile with over 2.5 million users to date across the UK, France, Italy, Spain and Germany. The doses are very small and the risks are minimal. If any do occur, they’re temporary.

Potential side effects may include:

  • Pain, redness or itching where the muscle relaxant injections are given
  • Nausea, headaches and hot flushes after injection
  • Another part of your body sweating more to compensate for the area treated (compensatory sweating)
  • Muscle weakness around the treated area.

Treatment usually takes around 15-20 minutes. There is no downtime and you can resume normal activities right away.

Many people find their procedure at The Cosmetic Skin Clinic more comfortable than expected. That’s because our medical practitioners are so highly skilled and precise. The injection procedure is simple to perform: you should merely feel a mild sting on your skin.
