Video transcript
Botulinum-toxin injections in the underarm area may help reduce excessive sweating. This can be particularly relevant for people who regularly wear close-fitting or light-coloured clothing or who are preparing for summer or an important event. The procedure is relatively quick, and the need for anaesthesia is assessed individually. The effect develops gradually over a few weeks. Its duration varies between patients and gradually diminishes over time. For many people, repeating treatment about once a year may be sufficient, but the clinician determines the interval.
Hyperhidrosis
Primary focal or secondary sweating
Primary focal hyperhidrosis usually begins younger, affects underarms, palms, soles, or face symmetrically, recurs at least weekly, and is generally absent during sleep. It can run in families and affect clothing, work, device use, and wellbeing.
Generalised, sudden-onset, or night sweating may relate to medicines, hormonal, metabolic, infectious, or other health factors. In such cases, identifying the cause matters more than simply blocking sweat-gland activity.
Common signs
- Symmetrical underarm, palm, or sole sweating
- Sweating without heat or exercise
- Interference with clothing, work, or grip
- Maceration, irritation, or recurrent infections
When to see a dermatologist
When to see a dermatologist
- Sweating began suddenly or became generalised
- It occurs at night or accompanies weight loss, fever, or palpitations
- Symptoms substantially disrupt daily life
- You want a procedure and need contraindication assessment
Accurate diagnosis
How assessment works
The clinician reviews age of onset, sites, symmetry, frequency, night symptoms, family history, medication, and other symptoms. Tests are not obligatory for typical primary focal disease but are targeted when a secondary cause is possible. Impact on quality of life also determines severity.
An individual plan
Treatment approach
Treatment is selected stepwise by site, severity, previous attempts, and patient priorities. A procedure is not the only option.
Medical antiperspirants
Aluminium-salt products are often first-line; correct use on dry skin reduces irritation.
Topical or systemic treatment
Selected sites may use prescription topical or oral medicines, balancing benefit against dryness and other adverse effects.
Botulinum toxin injections
Precise injections can temporarily reduce nerve signalling to sweat glands in underarms and selected other sites after assessment.

Botulinum toxin injections to reduce excessive sweating after assessment of causes, area, and possible functional effects.

What to expect
Effect and duration vary. Botulinum toxin usually develops over days and lasts several months before repeat treatment may be considered. Palms and soles can be more painful and need separate risk assessment. Secondary sweating is managed by addressing its cause.

Frequently asked questions
Is sweating a disease?
Sweating is normal; hyperhidrosis is excessive sweating disproportionate to cooling needs and disruptive to life.
Do injections stop all body sweating?
No. They act only in the treated area and do not switch off overall thermoregulation.
How long does the effect last?
Usually several months, although duration and repeat timing are individual.

Treatment starts with an accurate diagnosis
After assessment, the dermatologist will explain the appropriate plan and costs. There is no single fixed treatment price because it depends on the diagnosis and therapy required.
