Excessive Perspiration

Book an appointment

Botulinus toxin is used to control excessive perspiration by blocking the sweat glands. Underarms, the forehead, hands and feet are areas that are commonly treated. In 2001, Health Canada approved BOTOX and XEOMIN for the treatment of hyperhidrosis in the underarm area.

What is hyperhidrosis?

We talk about hyperhidrosis when there is excessive perspiration, that is when the quantity of sweat produced considerably exceeds the volume required for body thermoregulation. The role of perspiration is to contribute to thermal regulation in order to keep body temperature regular. The popular belief is that it is normal to perspire, regardless of the quantity.

According to published data, around 2.8% of the population suffers from hyperhidrosis, of which for 10% the condition is generalized and 90% is localized. The areas affected in particular are the underarms, the hands and the feet. Often there is a family history of the condition.

The discomfort created by this medical problem is not insignificant. People who suffer from excessive perspiration can give off an image of lack of cleanliness and of anxiety, as well as having their clothes ruined by sweat.

How does BOTOX work in cases of hyperhidrosis?

Once BOTOX/ XEOMIN is injected into the skin, it acts by preventing the release of acetylcholine in the nerve endings. This technique considerably reduces the activity of the sweat glands in the desired areas.

What happens during a treatment session?

The skin is first of all disinfected, then multiple superficial injections are made in the target area. A local anesthetic is necessary.

What are the possible side effects and the required recovery time?

There should be few side effects after BOTOX/ XEOMIN therapy for hyperhidrosis, although small bruises are possible.

How many treatments are required?

For the first treatment, we normally wait for the sweat glands to have been blocked for 4 months. From the second treatment onwards, the effective period of BOTOX/ XEOMIN is doubled and the sweat glands are blocked for around 8 months.

Is it possible to receive permanent treatment for hyperhidrosis?

For the underarm area, the miraDry laser is now available and has been approved by Health Canada in the treatment of axillary hyperhidrosis. However, this laser is not yet available at Dermaskin.
