What are anti-wrinkle injections for excessive sweating?

Excessive sweating, also known as hyperhidrosis, is a common condition and can have a serious impact on your confidence.

In addition to psychological issues, excessive sweating can also cause painful or irritating skin problems. From physical discomfort, to anxiety, embarrassment, and the stress of always hiding your sweat from others, hyperhidrosis can impact nearly all aspects of your life.

Anti-wrinkle injections have been used to treat excessive sweating since the early nineties. The injections use Botulinum Toxin A. Botox® is the trade name for this medicine made by Allergan, one of the world’s leading pharmaceutical companies.

At Manara Skin Clinics we only use Botox® and we source this directly from Allergan’s manufacturing plant in Westport, Co. Mayo.

What is Hyperhidrosis?
Hyperhidrosis is a medical condition where an individual experiences excessive perspiration – sweating beyond the amount needed for the body to maintain a constant internal (core) temperature of 37°C.

Hyperhidrosis can occur in two forms, focal or generalised hyperhidrosis. In focal hyperhidrosis, excessive sweating is localised to particular areas of the body and individuals are usually affected at the palms of the hands, soles of feet, axillae (under-arms), or face. In generalised hyperhidrosis, however, most of the body is affected.

Although hyperhidrosis is not a malignant condition, it is one that can have a severe psychological impact on the individual as it can have debilitating effects on their self-esteem, personal relationships and professional life. The most commonly affected domains include social relationships, self-expression, self-improvement, work, and active recreation.

What causes hyperhidrosis?
The exact cause of hyperhidrosis is not known.

In focal hyperhidrosis individuals already have a high production of sweat, and it has been found that an abnormal function of the central sympathetic nervous system also contributes.

The sympathetic nervous system is the portion of the nervous system that controls the body’s energy and resources during stress or arousal stimuli.

Therefore, when a person with focal hyperhidrosis experiences such stimuli (e.g. excitement or fear) their sweat glands produce even more perspiration.

What are the signs and symptoms of hyperhidrosis?
Hyperhidrosis can present at any age, but it tends to be highest among working-age adults. Individuals experience frequent staining and needing to change clothes. Due to the continual wetness, however, individuals who have axillary hyperhidrosis may experience a softening and whitening of the skin; allowing it to become easily infected and painful. As a result, complications such as bacterial or fungal overgrowth can occur and, in more serious cases, can cause muscle spasm and inflamed dermatitis.

What can be treated with anti-wrinkle injections for excessive sweating?

In some people, the body’s mechanism for cooling down is overactive, so overactive that they may sweat four to five times more than is necessary, or normal. This condition, called hyperhidrosis, affects mainly armpits, hands, feet and the groin. It can start in adolescence and affects men and women equally, occurring in 1-3 % of the population.

There are two main types of hyperhidrosis:

• Primary focal hyperhidrosis is the more common type and involves excessive sweating of the hands, feet and underarms.
• Secondary generalised hyperhidrosis is much less common and affects the whole body. It is usually caused by another illness like diabetes, an underactive thyroid or an infection.

More than 90% of people who present with excessive sweating will be diagnosed with primary focal hyperhidrosis.

While it’s important to document how excessive sweating impacts the quality of your life, it’s also key to understand what type of excessive sweating you have, to decide the best treatment.

What is involved in the treatment?

You will have a face to face consultation with your Doctor at Manara Skin Clinics to assess suitability for excessive sweating treatment. If you are suitable for treatment and decide to go ahead, your Doctor will discuss what areas are to be treated and apply a local anaesthetic cream.

A consent sheet is then signed, and the treatment itself can take from 15 to 30 minutes. The treatment uses a very delicate, thin needle to administer a series of tiny injections into the treatment area, which causes minimal discomfort for a few seconds. The Botox® blocks the action of the nerves that supply eccrine glands and stops them producing sweat.

An ice pack or numbing cream may be used to reduce the discomfort. It starts working 7 days after treatment, and it can take up to 14 days to see the full result.

How long will results last?

You should notice a difference about a week after treatment. If you do not have significant changes after two weeks we would ask that you to return for a follow up appointment. This treatment can last from 4 to 12 months. Every patient is different; skin condition, age and lifestyle are all factors. There is no cure for hyperhidrosis, however over time some patients have noticed symptoms improve with continued treatment.

Before and after

Before your treatment

Before you come for your treatment, please read our standard preparation advice. There is no specific additional preparation required for this treatment.

Following your treatment

Following your treatment you may feel tender and bruised, it’s important not to rub the affected areas. For the following 24 hours, avoid vigorous exercise, alcohol or extremes of heat. It is safe to fly after Botox® treatment. As Botox® has no recovery time, there is little aftercare required.

Side effects from the tiny needles may occur and include skin redness or little bumps lasting up to 30 minutes after treatment. Bruising is rare but may occur. We like to see all our new patients 2 to 3 weeks after their first treatment to assess the results and ensure they are happy with the results.
