Hyperhidrosis Treatment

Excessive sweating is known medically as hyperhidrosis. It’s a common condition that affects both men and women, whether through sweaty hands, sweaty feet, sweaty armpits, sweating at night or profuse sweating in general.

Hyperhidrosis is not a temporary condition and can cause people a great deal of embarrassment, but the good news is that it can be treated with botulinum toxin injections. 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.

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.

Botulinum toxin is injected into the skin to treat areas of the body affected: around 15-20 injections are given into the armpits, hands or feet 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.
