What is Hyperhidrosis?

Hyperhidrosis is defined as excessive and uncontrollable sweating in a particular body area.

Most of the time, hyperhidrosis is caused by an overactive nerve supply to the sweat glands that result in its overstimulation which leads to extra and at times, excessive sweat production.

Excessive sweating can be made worse by:

Heat / hot environment

Anxiety and stressful situations

In the sweltering and humid heat of Singapore, Hyperhidrosis can unfortunately lead to a negative impact on the quality of life for those affected.

Common areas to experience Hyperhidrosis

2 commonly treated areas are sweaty underams and sweaty palms.

Hyperhidrosis of the underarms (excessive underarm sweating) may cause staining of the clothes (a.k.a the pits stain) and body odour which may lead to socially embarrassing situations. 

Hyperhidrosis of the hands (sweaty palms) may also negatively impact self-confidence when one is needed to shake hands or hold hands with others during social interactions. 

The stress of psychological embarrassment and social stigma is usually the primary driving force behind individuals seeking treatment for excessive sweating.

Treatment Options

Various treatment options exist for effectively treating hyperhidrosis.

The least invasive treatment approach would be applying topical antiperspirants such as aluminum chloride solution which reduces sweat production by blocking the opening of the sweat ducts.

However, one side effect of topical antiperspirants is that patients may experience skin irritation (dermatitis) after prolonged application.

Surgery can help address the overactive nerve supply to the sweat glands which cause hyperhidrosis. However, since it is invasive, it is limited as the last resort. It is associated with other potential side effects such as neighboring nerve injury.

Dr Edwin prefers to use Botox injections to treat Hyperhidrosis as it is minimally invasive with little to no downtime, and is both safe and effective.

How does Botox help Hyperhidrosis?

Sweat glands produce sweat after being activated by a chemical that transmit signals to the nerves called acetylcholine.

Botox injections stop the release of acetylcholine from the overactive nerves supplying the sweat glands.

No signals = No sweat gland activation = No sweat production

Furthermore, Botox has been well studied in the treatment of hyperhidrosis and is reported to be both safe and more effective than topical anti perspirants.

Botox Underarm Sweating Treatment Experience

At the clinic, numbing cream will first be applied to the entire treatment area for around 30 minutes. The numbing cream will help reduce discomfort as much as possible.

Next, Dr Edwin will mark out the injection points to evenly cover the underarm. For example, each underarm may require 20 to 25 injection points to adequately target all the sweat glands.

Each injection point will contain 2 units of Botox.

The injections are administered using a tiny needle which feel like a small prick / ant bite. After injection, small mosquito bite like bumps containing the botox will be present throughout the treatment site.

These bumps will subside after 4 to 6 hours.

Patients are advised not to massage the botox bumps and to avoid cosmetics / makeup to the area on the day of the treatment.

Bruises and swelling are rare and can be improved with the application of the intensive recovery cream.

What is Botox?

Botox is a popular cosmetic treatment performed by doctors to improve the appearance of facial wrinkles and to treat certain muscular conditions like jaw grinding or oversized calf muscles.

How much Botox is needed?

Before deciding on the botox dosage, your doctor should discuss with you if you prefer a “natural” or more “frozen” appearance. Your doctor will also assess the severity and extent of the wrinkles before making a recommendation.

The “natural” look involves injecting a lower dose of botox with the intention to relax around 50% of the muscle movement. This method will improve the appearance of wrinkles and yet still retain some muscle movement. Since the muscles of facial expression are still active, you will have natural looking botox results.

The “frozen” look will require higher doses of botox to relax around 80-90% of the muscle movement. Since muscle movement is greatly reduced, there will be minimal wrinkles after treatment. However, because the face is less expressive, some may find that their appearance is less natural looking.

How is Botox measured?

Botox is measured in units. Just like how body weight is measured in kilograms, Botox is counted in units.

Usually, each injection point may contain between 1 to 4 units of Botox.

How long can Botox last for?

Depending on the dosage, on average, Botox can last between 3 to 4 months.

Higher doses such as those given for a “frozen” appearance may last up to 6 months.
