What Is Excessive Sweating (Hyperhidrosis)?
Sweating is a natural process that helps regulate your body temperature. With hyperhidrosis, however, the sweat glands become overactive and produce far more perspiration than is necessary for cooling.
While hyperhidrosis can affect various areas of the body, it most commonly impacts the underarms (axillary hyperhidrosis). For many people, this is a primary condition, meaning it occurs on its own without an underlying medical trigger, and causes sweating even when you are cold, resting, or not exercising.
Excessive underarm sweating can quickly become an everyday burden, affecting your clothing choices, social interactions, professional confidence, and general comfort. It affects both men and women equally, but it is a manageable condition. If persistent sweating is impacting your daily life, a private clinical assessment can help determine the right treatment plan for you.
What Causes Excessive Sweating?
Excessive sweating can be triggered by different factors depending on the type of hyperhidrosis you have:
- Primary (Idiopathic) Hyperhidrosis: This is the most common form of excessive sweating. It occurs when the nervous system signals the sweat glands to become overactive, even without triggers like heat or exercise. It typically targets specific areas (most commonly the underarms) and has no underlying medical cause, though genetics often play a role.
- Secondary Hyperhidrosis: This type occurs when excessive sweating is caused by an underlying medical condition or external factor, such as hormonal changes (e.g., menopause), thyroid issues, anxiety, or side effects from specific medications.
Because the underlying cause varies from person to person, a clinical assessment is an essential first step. During your consultation, we review where sweating occurs, your medical history, and how significantly it impacts your daily routine to confirm suitability for treatment.
Excessive Sweating (Hyperhidrosis) Treatment Information
Below, you will find essential information about excessive sweating treatment with Dr Preema at our Mayfair clinic, including expected treatment times, result duration, and maintenance recommendations.
Treatment Time
How long does a hyperhidrosis treatment take?
A treatment for excessive sweating typically takes around 30 minutes.
The appointment includes preparation of the treatment area and a series of small injections, making hyperhidrosis treatment a relatively quick procedure that can be easily fitted into your day.
Comfort Level
What does hyperhidrosis treatment feel like?
Hyperhidrosis treatment is generally well tolerated, although you may feel a series of small pinpricks during the injections.
A topical numbing cream may be applied beforehand where appropriate to help make the treatment as comfortable as possible.
Course Frequency
How many hyperhidrosis treatments are needed?
Most patients require a single treatment session to reduce excessive sweating in the targeted area.
Your practitioner will assess the severity of your hyperhidrosis and create a personalised treatment plan based on your symptoms, treatment area and individual response.
Action to Take Effect
How soon does hyperhidrosis treatment start working?
You may begin to notice a reduction in excessive sweating within 1–14 days of treatment.
Results typically continue to develop over the following 1–2 weeks as the treatment takes full effect, helping to reduce sweat production in the treated area.
Duration of Effect
How long do hyperhidrosis treatment results last?
The effects of hyperhidrosis treatment typically last around 6–9 months, although this can vary between patients and treatment areas.
Over time, the effects gradually wear off and normal sweat production may begin to return.
Maintenance
How often should you have hyperhidrosis maintenance treatments?
We generally recommend repeat treatment when the effects begin to wear off but we offer a review around 2 – 4 weeks.
Your practitioner will advise on the most suitable maintenance schedule to help provide ongoing control of excessive sweating and maintain your results.
How Effective Is Excessive Sweating Treatment?
Botox is widely recognised as one of the most effective non-surgical treatments for hyperhidrosis. For patients receiving underarm injections, treatment typically achieves an 80–90% reduction in perspiration.
Because Botox provides temporary symptom relief rather than a permanent cure, maintenance sessions are required to sustain optimal results.
What Treatments Are Available for Excessive Sweating?
There is no single hyperhidrosis treatment that works for everyone. The best approach depends on the primary area affected, severity of symptoms, previous treatments tried, and individual suitability established during clinical assessment.
Management options range from medical-grade topical antiperspirants and prescription oral medications to non-surgical injectable treatments and surgical interventions. The comparison table below highlights the key differences between available options to help you understand your choices prior to consultation.
| Treatment option | Where / when it may be considered | Role in management | Key considerations / availability |
|---|---|---|---|
| Topical & prescription antiperspirants | May be considered for excessive sweating depending on the area affected and the individual. | Can form part of the management of excessive sweating. Persistent symptoms may lead people to consider other treatment options. | Relevance varies by treatment area and individual circumstances, so professional assessment helps guide the most appropriate pathway. |
| Botulinum toxin injections | An established injectable approach used to reduce excessive sweating in targeted areas. | At Dr Preema London Clinic, Botox is offered for excessive underarm sweating as a targeted treatment option. | Offered as a discreet, non-surgical treatment with no downtime. Suitability depends on individual assessment. |
| Iontophoresis | Often discussed in relation to area-specific hyperhidrosis, including excessive sweating of the hands. | May be considered as another management approach within an individual treatment pathway. | Whether it is relevant depends on the individual concern, the area affected and the wider treatment plan being considered. |
| Medication | May be considered within the wider range of approaches to excessive sweating. | Can form part of a broader management pathway where clinically appropriate. | Medication is not presented as a standalone treatment service on this page. Appropriate medical assessment is important when considering whether it is relevant. |
| Other sweat-reduction treatments | Device-based or sweat-gland treatment approaches may be available for particular types of excessive sweating. | These approaches may sit within a broader range of options when treatment needs are area-specific or symptoms persist. | The most appropriate option depends on factors including the treatment area, severity of symptoms and individual circumstances. |
| Surgery for hyperhidrosis | Surgical approaches exist within the wider spectrum of hyperhidrosis treatment. | Surgery represents a different treatment pathway from the non-surgical injectable treatment provided at Dr Preema London Clinic. | Surgical treatment requires appropriate specialist assessment. |
Which Areas Can Be Affected by Excessive Sweating (Hyperhydrosis)?
Hyperhidrosis can occur in several regions of the body. Identifying the specific area affected is essential, as treatment suitability varies depending on the location of your symptoms.
- Underarms (Axillary Hyperhidrosis): This is the most common form of excessive sweating and the primary area we treat at Dr Preema London Clinic. Underarm hyperhidrosis often leads to visible sweat patches, clothing stains, and daily discomfort, but responds exceptionally well to targeted Botox injections.
- Hands (Palmar Hyperhidrosis): Sweaty palms can interfere with daily tasks, holding objects, and physical contact like handshakes. Because hand treatment requires specific clinical considerations, individual assessment is essential.
- Face and Scalp (Facial Hyperhidrosis): Excessive sweating around the forehead, face, or scalp can impact personal and professional confidence, particularly in warm environment or stressful situations.
- Feet (Plantar Hyperhidrosis): Sweaty feet are a common concern that can cause physical discomfort and footwear damage, requiring tailored management strategies.
During your private consultation in Mayfair, Dr Preema will evaluate your primary areas of concern and discuss whether underarm Botox or alternative management strategies are right for you.

Frequently Asked Questions About Botox for Excessive Sweating
Does Botox really work for excessive sweating?
Yes. Botulinum toxin type A can significantly reduce excessive underarm sweating by temporarily blocking the nerve signals that activate the sweat glands. Botox is licensed in the UK for severe primary axillary hyperhidrosis that has not responded to topical treatments such as antiperspirants.
How long does Botox last for excessive sweating?
Botox for underarm sweating typically lasts around 4–7 months, although the duration varies between individuals. As the nerve signals gradually recover, sweating will return and the treatment can be repeated when needed. The British Association of Dermatologists notes that some people may experience benefits for longer.
What are the risks and downsides of Botox for sweating?
The most common side effect is temporary pain at the injection sites. Other possible effects include swelling, irritation, bruising, headache and increased sweating elsewhere on the body. Muscle weakness is uncommon. Results are also temporary, meaning repeat treatments are usually needed to maintain the reduction in sweating.
Is Botox for sweating worth it?
Botox may be worth considering if excessive sweating significantly affects your confidence, clothing choices, work or daily life and treatments such as strong antiperspirants have not helped. It can provide several months of reduced sweating, but results are temporary and ongoing treatments involve additional cost. Suitability should be assessed individually.
Can Botox permanently cure hyperhidrosis?
No. Botox does not permanently cure hyperhidrosis. It temporarily interrupts the nerve signals that stimulate sweat glands, reducing sweating in the treated area for several months. Primary hyperhidrosis is often a long-term condition, although symptoms can change over time. Other treatments, including iontophoresis, medication and, in selected severe cases, surgery, may also be considered.
