Perspiration is a normal and healthy way for the body to regulate temperature, but for some people, it can be excessive, unpredictable, and deeply uncomfortable. If you often find yourself changing clothes, feeling self-conscious about odour, or avoiding handshakes because of clammy palms, you may be experiencing hyperhidrosis (excessive sweating).
At Omniya Clinic in Knightsbridge, London, we offer Botox injections for hyperhidrosis, an MHRA-approved treatment proven to reduce excessive sweating by up to 80%. This safe, doctor-led procedure targets overactive sweat glands to deliver long-lasting relief, helping you feel comfortable and confident again in everyday situations.
Hyperhidrosis is a medical condition in which the sweat glands are overactive, producing more sweat than the body needs to regulate temperature. It can occur even when you’re not hot, anxious, or exercising, and may affect specific areas such as:
For many people, the effects extend far beyond physical discomfort. Excessive sweating can limit wardrobe choices, affect professional confidence, and cause social anxiety or embarrassment, impacting overall quality of life.
Causes of hyperhidrosis vary. In some cases, it’s primary (idiopathic) hyperhidrosis, which means there’s no clear medical cause and it may run in families. In others, it’s secondary hyperhidrosis, linked to underlying conditions such as thyroid disorders, diabetes, or menopause.
Before starting treatment, it’s important to rule out any underlying causes with your GP to ensure the most appropriate and effective management plan.
While Botox is best known for reducing fine lines and wrinkles, it’s also an MHRA and FDA-approved medical treatment for excessive sweating. When injected just beneath the skin, botulinum toxin blocks the nerve signals that activate the sweat glands. As a result, the treated glands temporarily stop producing sweat, without affecting your body’s ability to regulate temperature elsewhere.
According to the NHS, Botox is a recognised medical treatment for severe underarm sweating (axillary hyperhidrosis) when other antiperspirants have not worked. At Omniya Clinic, our experienced practitioners use precise, targeted injections to deliver reliable results with minimal discomfort.
Your journey begins with a comprehensive consultation with one of our experienced doctors at Omniya Clinic in Knightsbridge. During this appointment, we’ll review your medical history, discuss your symptoms, and assess the areas most affected by sweating. You’ll have the opportunity to ask questions and understand exactly how Botox works, ensuring the treatment is right for you.
This is a quick, well-tolerated procedure with minimal discomfort and no need for downtime.
Our clinicians will provide personalised aftercare advice to support optimal results and comfort. You can expect to notice a gradual reduction in sweating within a few days, with full results typically visible in about two weeks.
Most patients begin to notice a reduction in sweating within 3 to 7 days after treatment, with the full effects visible by 10 to 14 days. The results are both measurable and life-changing for many who have struggled with excessive sweating for years.
As sweating gradually returns, treatment can be safely repeated. Many patients find that regular sessions help maintain longer-lasting dryness over time, as the sweat glands become less active with each course.

Botox is not recommended for generalised full-body sweating or areas with infection or broken skin. Treatment is always localised and targeted for precision and safety.
varies per patient
Your clinician will begin with a thorough consultation to ensure you may be suitable for Botox for sweating. This will include assessing the areas where you experience excessive sweating. The treatment itself is straightforward and typically lasts about 15-30 minutes.
Using fine needles, Botox is injected into the targeted areas to block the sweat glands. Most patients report minimal discomfort, and there is no need for downtime after the procedure. You can resume your usual activities immediately.
After undergoing Botox treatment for hyperhidrosis, patients typically notice a significant reduction in sweat production within two weeks. For underarm treatments, the effects generally last between 4 to 6 months on average, although some patients experience longer lasting results. When sweating begins to return, patients can opt for follow-up treatments.
The ability to regain control over excessive sweating can dramatically improve quality of life, giving individuals the confidence to wear a broader range of clothing without the worry of sweat stains or odour.
Botox is becoming an increasingly popular treatment for hyperhidrosis, particularly in the UK. A 2016 study estimated that approximately 365,000 people in the UK suffer from severe hyperhidrosis that significantly impacts their lives. While not everyone with hyperhidrosis requires Botox, many individuals find it a life-changing option after exhausting other treatments. More recent data suggest that Botox is one of the most sought-after solutions for managing excessive sweating, especially among those aged between 20 and 50, who are often most affected by the condition.
At Omniya Clinic, the cost of Botox for hyperhidrosis starts at £500 per session. The price varies depending on the size of the treatment area and the number of injections required. During your consultation, we will provide a personalised plan tailored to your specific needs, ensuring that you receive the best possible outcome, and you will be informed of your suitability and cost of treatment during your consultation.
Hyperhidrosis is considered to be caused by a problem with the body’s nervous system. In particular, it is the part that controls sweating. It can be triggered by pregnancy, menopause, anxiety, low blood sugar, overactive thyroid, infections and medication.
