Everyone sweats. Even though the process can be unpleasant, it's the body's natural way of preventing the dangers of over-heating. The way sweating works is straightforward. When your body warms up, salty water evaporates off the surface of the skin, thereby cooling you down.

However, for some people, sweating isn't so simple. In fact, for about 3% of us, it happens way too much. If you sweat excessively, you might be experiencing a condition known as hyperhidrosis. In severe cases, sufferers lose as many as 14 litres of fluid within a 24-hour period. People with hyperhidrosis perspire in all kinds of weather, even on cold, frosty days.

Hyperhidrosis can lead to discomfort, self-consciousness and embarrassment because sweat is easily visible. The condition most commonly affects the arm pits, feet, palms, face and head. While some people experience it in a particular area, others sweat all over the body.

What are the benefits of hyperhidrosis injections?

The benefits of hyperhidrosis injections are usually felt quickly. This injectable works as soon as it enters your body, so you go from feeling sweaty and uncomfortable to dry within a few days. If you've heard that the process causes sweat to travel to another part of the body, take no notice: this isn't true. The only thing that happens is the halting of the gland that's been working in overdrive. Other muscles – even those nearby – are not impacted.

Key Facts

Frequently Asked Questions
What does getting hyperhidrosis injections involve?
Using an extremely fine needle, your qualified therapist injects the affected area, penetrating to just beneath the skin's surface. These injections are applied in a grid pattern, with each point of entry separated by 10-20 millimetres. A skilled, experienced therapist should be able to complete both armpits within ten minutes.
How many hyperhidrosis injections do I need?
Usually, treatment requires multiple hyperhidrosis injections. However, before commencing, your therapist should take a close look at the affected area, to determine exactly how many injections are necessary. Furthermore, after receiving treatment, you should attend a follow-up appointment, which allows your therapist to make sure the first round was thorough. Insufficient injections can lead to unsatisfactory results.
Are hyperhidrosis injections painful?
Hyperhidrosis injections don't usually cause pressure or discomfort. However, if you're particularly sensitive, your therapist will provide strategies for numbing the pain. These might include ice, a topical anaesthetic and/or vibration analgesia.
How long do hyperhidrosis injections take to work?
Fortunately, hyperhidrosis injections work quickly. If excessive sweating has been driving you mad, you can look forward to quick relief. For most people, results start to take effect within a couple of days and no longer than two weeks.
How long do hyperhidrosis injections last?
Expect to enjoy the relief provided by hyperhidrosis injections for at least six months, and maybe as long as twelve months. That said, it's not a permanent solution. Unless the underlying cause of your hyperhidrosis can be resolved, you will need continuing treatment.
Which parts of the body can benefit from hyperhidrosis injections?

Hyperhidrosis injections can be used all over the body; however, in most cases, they are applied to the armpits. In this area, they are usually successful in reducing sweating by up to 87%. The statistics for palms are also impressive, with hyperhidrosis injections decreasing up to 90% of sweating.

If you're considering getting hyperhidrosis injections for your face, you should take heed. To be accurate, such injections should be applied by a highly-skilled practitioner. In rare cases, hyperhidrosis injectables can lead to asymmetry of the face, especially the forehead.

How do I prepare for hyperhidrosis injections?
Hyperhidrosis injections do not require excessive preparation, but, in the lead-up, it is a good idea to avoid shaving. Many therapists request that you allow hair growth for at least four days before a hyperhidrosis injection session.
After Care
What happens after hyperhidrosis injections?

The aftermath of hyperhidrosis injections does not involve any complex care procedures. Most people can receive injections and get straight back to work. That said, for a minimum of 24 hours, you should avoid any activities that cause heavy sweating or heat production, such as strenuous exercise, hot showers, hot baths and saunas.

Before booking hyperhidrosis injections, be sure to undergo an extensive consultation with your therapist. Let him/her know of your medical history and any sensitivities you have. Don't be afraid to ask questions about any aspect of the treatment that concerns you. As with all beauty therapy, you shouldn't start until you feel completely confident.
