Botox For Excessive Sweating (Hyperhidrosis)

at Omniya Clinic in London

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.

What Is Hyperhidrosis?

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:

  • Underarms (axillary hyperhidrosis)
  • Palms of the hands
  • Soles of the feet
  • Face or scalp
  • Chest or back

 

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.

How Botox Treats Hyperhidrosis

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.

Benefits of Botox for Hyperhidrosis

  • Up to 80% reduction in sweating
  • Quick and comfortable procedure (around 30 minutes)
  • No downtime – you can return to normal activities straight away
  • Effective for underarms, palms, feet, scalp, face and more
  • Results typically last 4-6 months

 

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 Treatment Journey at Omniya Clinic

1. Consultation

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.

2. During the Procedure

  • A topical numbing cream may be applied beforehand for comfort.
  • Using ultra-fine needles, your practitioner will inject small amounts of Botox into the affected area (typically 10-15) injections per underarm.
  • The procedure usually takes around 30 minutes to complete.
  • Most patients describe the sensation as a mild sting or pinprick.

 

This is a quick, well-tolerated procedure with minimal discomfort and no need for downtime.

3. Aftercare

  • You can resume normal activities immediately after treatment.
  • Avoid hot showers, saunas, or intense exercise for 24 hours.
  • Refrain from using deodorants or tight clothing over the treated area for 12 hours.

 

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.

Results and Longevity

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.

What to Expect

  • A significant reduction in sweating in the treated area
  • Improved comfort and dryness throughout the day
  • The confidence to wear lighter clothing without worry
  • Results lasting 4 to 6 months, sometimes longer with consistent treatment

 

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.

“I used to worry about sweat marks every day – now I don’t even think about it. It’s genuinely life-changing.” – Omniya patient review (Google)

For many, Botox for hyperhidrosis doesn’t just reduce physical symptoms, it restores comfort, confidence, and peace of mind in social and professional settings alike.

Is Botox Safe for Hyperhidrosis, and Which Areas Can Be Treated?

Yes. Botox has been safely used in both medical and aesthetic treatments for over two decades. When administered by qualified practitioners, it’s a low-risk and highly effective procedure for managing excessive sweating. At Omniya Clinic, all treatments are carried out by experienced medical professionals to ensure your safety and comfort.

Possible Side Effects

  • Mild redness, tenderness, or bruising at the injection site
  • Temporary muscle weakness (for example, a slight reduction in hand grip strength if palms are treated)

 

These effects are temporary and typically resolve within a few days.

Who Should Avoid Botox for Sweating

You may not be suitable for treatment if you:

  • Are pregnant or breastfeeding
  • Have an allergy to Botox or any of its ingredients
  • Have a neuromuscular disorder such as myasthenia gravis

 

Before any procedure, we’ll take a comprehensive medical history to ensure Botox is safe and appropriate for you.

Commonly Treated Areas

  • Underarms (axillary hyperhidrosis)
  • Palms of the hands
  • Soles of the feet
  • Forehead or scalp
  • Chest or back (in selected cases)

 

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.

The Procedure

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.

Expected Results

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.
