Fighting off perspiration

August 2017
Perspiration is a normal physiological phenomenon which helps control body heat and maintains a constant temperature of approximately 37°C. Perspiration allows the body to cool down. Sweat produced by the sudoriferous glands helps the body control it's temperature during physical activity and hot conditions. When deodorants and anti-perspirants are not enough to treat excessive perspiration then other treatments are required.



Perspiration remains a taboo subject and few people fell able to talk about it. Approximately 1 percent of the population have perspiration problems. Perspiring is a normal physiological phenomenon which helps controls the body temperature at approximately 37°C.

Perspiration allows the body to cool. The temperature control of the body is carried out by sweat produced by the sudoriferous glands. Physical activity or exposure to heat increases the temperature of the body. The body reacts in order to lower its temperature by producing sweat, which evaporates after.

Deodorants


Action

  • Traditional deodorants hide bad smells.
  • The daily use of deodorant is a normal practice for most people.
  • Deodorants do not limit the flow of perspiration
  • Most deodorants contain substances, which hide the smells or decrease the multiplication of bacteria.

Anti-perspirant deodorants

Some deodorants contain aluminum salts, which have an anti-perspiring properties.

Anti-perspirants

Action

Anti-perspirants limit the secretion of sweat from the sudoriferous glands. These products are recommended by doctors, in particular by dermatologists, and are usually first line treatment for problems of excessive perspiration. They act on the causes of perspiration and to control its flow. The majority of anti-perspirants contain aluminum salts, which act directly on the diameter of the sudoriferous canal. Anti-perspirants come in lotions, stick or roll-ons, or creams. These products are available at chemists, sold on the Internet or available on prescription.

Method of use

Two to three applications per week are enough:
  • Use the anti-perspiration products only every 2-3 days.
  • Apply the product in the evening, on a dry and clean skin, in order to allow the product to penetrate during the night in the sudoriferous glands and avoid any irritation.
  • Do not apply these products after hair removal or shaving within 2 days.

Botox injections

How can a botox injections decrease perspiration?

  • The treatment is based on subcutaneous injections of botulinum toxin.
  • Botulinum toxin is very beneficial for people who perspire a lot by preventing the nervous system from transmitting a message to the sudoriferous glands, thus inhibiting the sudoriferous glands from secreting sweat.

Efficiency and methods of treatment

  • The botulinum toxin works within two to three days.
  • The effectiveness of the treatment lasts approximately 4 - 6 months: it is therefore necessary to renew injections at regular intervals.

Armpits and feet

  • For hyperhydrosis, botox injections are used for the armpits and feet and approximately 10 injections are necessary.

Iontophoresis

  • Iontophoresis consists of using an electrical current, passed through water. Hands, feet and armpits can be treated this way.
  • The way in which this helps hyperhydrosis is not exactly known, but it is thought to block the chemical messages to the sudoriferous glands therefore block the secretion of sweat.
  • Iontophoresis is recommended for cases of moderate hyperhydrosis of the hands or feet.
  • 2 to 4 sessions of approximately 20 - 40 minutes per week is recommended until improvement.
  • The hands or feet are soaked for 20 - 40 minutes in vats filled with water where an electric current is passed through the water.
  • Dermatologists recommend ongoing treatment to control symptoms. The disadvantage of this is that it can be time consuming attending the hospital every week.

Surgery

  • Surgery is considered when all other methods show no improvement.
  • In addition, surgery is more often advised for excessive perspiration of the hands, because botox injections in the hands can present with a risk of paralysis of certain nerves, which are essential for grasping objects.
  • Surgery can consist of: surgical excision of the sudoriferous glands, scraping of the sudoriferious glands, laser ablation of the sudoriferous glands, and inactivation of some nerves through cutting some of the nerves that run down the side of the spinal cord.
