Overview
Sweating is a natural and essential function that helps regulate body temperature. However, in hyperhidrosis, the sweat glands become overactive, producing perspiration beyond what the body requires.
This can occur even when the body is at rest or in a cool environment. In many cases, there is no identifiable underlying cause (known as primary hyperhidrosis), although it can sometimes be linked to medical conditions or hormonal changes.
How we approach excessive sweating
At Mirabel, excessive sweating is approached by focusing on the overactive nerve signals that trigger the sweat glands, rather than the surface of the skin alone.
The aim is to:
• Reduce excessive sweat production in targeted areas
• Improve day-to-day comfort and confidence
• Provide a controlled, predictable reduction in sweating
• Maintain normal function in the rest of the body
Treatment is carefully tailored to the area affected and the severity of the condition, allowing for a subtle but effective result.
Botulinum toxin is commonly used to treat excessive sweating by blocking the nerve signals that activate the sweat glands, preventing them from producing excess sweat in the treated area.

What you may notice
Excessive sweating can present in ways that feel disproportionate to the situation:
• Noticeable sweating without heat, exercise or exertion
• Damp patches on clothing, particularly under the arms
• Sweating that feels difficult to control or predict
For many people, the visibility of sweating can feel more impactful than the physical sensation itself.
What is happening in the body
Excessive sweating occurs when the nerves that control the sweat glands become overactive.
This means:
• Sweat glands are triggered more frequently than necessary
• Signals are sent even when the body does not need cooling
• Localised areas produce disproportionate amounts of sweat
Botulinum toxin works by interrupting these nerve signals, preventing the glands from being activated in the treated area.
This targeted approach allows sweating to be reduced without affecting the body’s overall ability to regulate temperature.
What can influence excessive sweating
Excessive sweating can be influenced by a number of factors:
• Genetics, particularly in primary hyperhidrosis
• Hormonal changes
• Stress or emotional triggers
• Underlying medical conditions in some cases
• Certain medications
While triggers may vary, the underlying mechanism is often related to overactive signalling between the nerves and sweat glands.
When to seek advice
If sweating feels excessive, unpredictable or is affecting your confidence or daily activities, a more tailored approach can help to manage it effectively.
Seeking advice can help to:
• Determine whether the sweating is primary or linked to another cause
• Identify the most appropriate treatment approach
• Reduce symptoms in a controlled and targeted way
• Improve comfort and confidence in everyday situations
