What does Dr. Hallam say about excessive sweating?

Botox injections into the skin are an extremely effective and safe solution for excessive sweating, a condition known as hyperhidrosis. Improvement can be dramatic and I have seen lives transformed by this treatment in those who are badly affected..

Many people who are unhappy with milder or normal sweating also find this beneficial, especially in the summer months. Working closely with others, hot work places, stressful situations, or big events such as a wedding all contribute to the discomfort of sweating.

Areas most suitable are under the arms, the forehead and scalp.

It is possible to treat hands and feet, but these areas are very painful, especially the feet, and I would normally recommend iontophoresis for these parts of the body.


What is Hyperhidrosis?

Sweating is the body’s way of regulating its temperature and everybody sweats. Excessive sweating or hyperhidrosis is a condition that affects about 1% of the population. It usually manifests in people between the ages of 18 and 35, but the condition normally improves, as we get older.
Hyperhidrosis can also be the result of an underlying condition such as diabetes or an overactive thyroid gland. For these people, treatment of the underlying cause may also help to resolve the problem.

Triggers that can induce excessive sweating may include:
bullet  Exercise
bullet  Alcohol, coffee and tea
bullet  Stress and anxiety
bullet  Hot or spicy food

How is Botox ® used to treat excessive sweating?

The skin of the treatment area is cleaned. Then tiny injections are made close to the skin surface 1-2 cm apart. It is quick, and surprisingly, virtually pain free.

I would recommend shaving under the arms prior to arriving, but this is not necessary for the scalp.

Sweating reduces between days 5 and 10. By 2 weeks you can expect a reduction in sweating of 80-100%.

How long does the treatment last for?

The effect wears off gradually and depends how heavy the sweating was prior to treatment. In my experience Botox will last 8-12 months, Azzulure will last 6-9 months, but this can vary.

Are there any alternative treatments?

Yes. Aluminium chloride antiperspirants can be prescribed by your GP, though they are often quite irritable to the skin. Iontophorisis is a safe treatment more suitable for hands and feet than the scalp forehead or under arms. Surgery to the nerves supplying the sweat glands can be carried out.


    In order to get the best results after Botox® treatment for Hyperhidrosis, the following guidelines should be followed:
    bullet  Avoid wearing deodorant for 24 hours after the treatment.
    bullet  Avoid consuming excessive alcohol for 24 hours after the treatment.
    bullet  Do not massage the treated areas.
    bullet  Do not do any aerobic exercise for 24 hours after the treatment.
