Targeted Treatment for Excessive Underarm Sweating
Axillary hyperhidrosis is a condition characterised by excessive sweating of the underarms, often beyond what is required for normal temperature regulation.
Botulinum toxin injections provide an effective, targeted treatment by reducing activity in the sweat glands, helping restore comfort and confidence.
Understanding Hyperhidrosis
Sweating is a normal physiological process, but in hyperhidrosis it becomes:
- Excessive and difficult to control
- Unrelated to temperature or physical exertion
- Disruptive to daily activities and clothing choices
Axillary hyperhidrosis affects the underarms and is one of the most common forms of the condition.
When Treatment Is Considered
Treatment may be appropriate if:
- Sweating interferes with daily life
- Clothing is regularly marked or affected
- Topical treatments (e.g. strong antiperspirants) have been ineffective
- The condition causes social or professional discomfort
Botulinum toxin is typically used when simpler measures are insufficient.
How Botulinum Toxin Works
Botulinum toxin blocks the signals between nerves and sweat glands.
When used in the underarm:
- Sweat production is significantly reduced
- The effect is localised to the treated area
- Normal thermoregulation elsewhere is unaffected
This provides a controlled reduction in sweating without altering overall body function.
The Procedure
Treatment is performed in clinic.
- The area is mapped and prepared
- A series of small injections are placed into the underarm skin
- The procedure is quick and well tolerated
Local anaesthetic measures can be used to improve comfort if required.
Recovery
Recovery is straightforward.
- Normal activities can be resumed immediately
- Mild tenderness or redness may occur temporarily
- No significant downtime is required
Results
Botulinum toxin is highly effective for axillary hyperhidrosis.
Patients typically experience:
- Significant reduction in underarm sweating
- Improved comfort and confidence
- Better tolerance of clothing and daily activities
Results develop over several days and often last 4–6 months, after which treatment can be repeated.
Risks and Considerations
Treatment is generally safe, but potential effects include:
- Temporary tenderness or bruising
- Localised discomfort
- Very rarely, reduced effect over time
Systemic side effects are not expected when treatment is performed correctly.
Consultation
A consultation allows confirmation of the diagnosis and discussion of whether treatment is appropriate.
