Hyperhidrosis, or excessive sweating, is a very common condition affecting millions worldwide. It can lead to discomfort, social anxiety, and a significant impact on quality of life. One of the most effective treatments for this condition is the use of botulinum toxin (commonly known as Botox). Let's explore the details of Botox treatment for underarm sweating, including its efficacy, the procedure itself, the benefits, and potential side effects.
What is hyperhidrosis?
Hyperhidrosis is characterised by excessive sweating beyond what is necessary for thermoregulation. While the exact cause of primary hyperhidrosis remains unknown, it is believed to involve overactive sweat glands. Secondary hyperhidrosis, on the other hand, is usually linked to underlying medical conditions or medication side effects.
How does Botox reduce sweating?
Botox is a neurotoxin derived from the bacterium, Clostridium botulinum. It works by blocking the release of acetylcholine, a neurotransmitter that signals the activation of sweat glands. By inhibiting this signal, Botox effectively reduces sweat production in the treated areas.
Botox is an approved treatment for axillary (underarm) hyperhidrosis. The treatment involves injecting small amounts of Botox directly into the skin where excessive sweating occurs. The toxin then blocks the nerves responsible for activating the sweat glands, leading to a significant reduction in sweating.
The Procedure
The procedure of Botox treatment for hyperhidrosis is relatively straightforward and minimally invasive. Here’s what our clients can expect during the procedure:
Consultation: The process begins with a consultation where Dr Nicole will assess the severity of hyperhidrosis and discusses the clients medical history and treatment goals.
Preparation: Prior to the procedure, the treatment area is cleaned, and a topical anaesthetic is applied to minimise discomfort.
Injection: Using a fine needle, Dr Nicole administers multiple small injections of Botox just below the skin surface.
Post-Treatment Care: After the injections, clients can usually resume most normal activities immediately. However, we recommend avoiding strenuous activities and hot environments for 24 hours post procedure to prevent excessive sweating that could wash away the Botox before it has time to take effect. All of our clients will receive an aftercare leaflet.
Efficacy of Botox for Hyperhidrosis
Botox is highly effective in reducing excessive sweating. Research has shown that Botox can reduce underarm sweating by up to 87%. The results typically become noticeable within 4 to 7 days after treatment, with the full effect apparent by two weeks. The duration of the effect varies, but most patients experience relief for 6-9 months, after which repeat treatments are necessary to maintain the results.
Benefits of Botox treatment for treating hyperhidrosis:
1. Very effective: Botox provides significant and consistent reduction in sweating
2. Minimally invasive and fast recovery times
3. Quick procedure
4. Minimal Downtime
5. Prolonged results: Usually 6-9 months
Potential Side Effects and Considerations
1. Discomfort: Some patients may experience mild pain, swelling, or bruising at the injection sites. These effects are usually mild and temporary.
2. Allergic Reactions: Allergic reactions to botox are rare, however it is crucial to discuss any known allergies with Dr Nicole before treatment.
3. The effects of Botox are not permanent (although usually last 6-9 months), requiring ongoing treatments to maintain the desired level of sweat reduction.
Botox is suitable for individuals who experience excessive sweating that interferes with their daily lives. Ideal candidates are those who are in good overall health, do not have a history of neuromuscular disorders, and are not pregnant or breastfeeding.
