Anti Sweat Injections

Anti sweat injections by GMC Specialist Register plastic surgeons. Treatment for axillary hyperhidrosis. From £950 both underarms. CQC-regulated Baker Street clinic.

Anti Sweat Injections at Centre for Surgery, London

Anti sweat injections in summary: Botulinum toxin precisely placed in a grid pattern across the underarm skin to block nerve signals to the sweat glands, dramatically reducing or eliminating excessive underarm sweating for 6–9 months. Performed exclusively by GMC Specialist Register plastic surgeons at Centre for Surgery — not nurses or non-specialist doctors. Treatment is the gold-standard non-surgical option for axillary hyperhidrosis (excessive underarm sweating) and is licensed in the UK for this indication. Treatment takes 10–15 minutes; effects appear within 3–7 days. From £950 for both underarms. CQC-regulated clinic, 0% APR finance available subject to status.

Plastic surgeon-led, not nurse-led. Most London anti-sweat treatment is delivered by aesthetic nurses. At Centre for Surgery, every treatment is performed by a GMC Specialist Register plastic surgeon. Hyperhidrosis treatment requires precise mapping of the active sweating zone (using the Minor’s iodine-starch test or visual assessment), grid-pattern injection across the affected skin, and careful dose calibration. Surgeon-level placement ensures full coverage and consistent dosing — particularly important for patients with severe symptoms, those with previous incomplete treatment elsewhere, or those needing palmar/plantar treatment where anatomical knowledge of underlying muscles is critical to avoid grip weakness or foot dexterity issues.

Hyperhidrosis (excessive sweating beyond what the body needs for thermoregulation) affects roughly 1–3% of UK adults. The condition causes daily soaked clothing, repeated outfit changes, professional and social impact, and significant quality-of-life burden. Botulinum toxin is licensed in the UK for severe primary axillary hyperhidrosis that hasn’t responded to topical antiperspirant treatment, and is the established first-line option for patients who haven’t found relief from over-the-counter or prescription antiperspirants.

For patients seeking longer-lasting relief, surgical suction curettage offers significant long-term reduction — see our for details.

Understanding Hyperhidrosis (Excessive Sweating)

Hyperhidrosis is excessive sweating that goes beyond what the body needs to regulate temperature. Affected individuals sweat in cool environments, when not exercising, and when not stressed — often soaking through clothing daily and significantly affecting work, social life, and self-confidence.

The plastic surgeon will ask about your sweating pattern at consultation to confirm primary hyperhidrosis. Whole-body sweating, night sweats, sudden onset in adulthood, weight changes, fevers, or other systemic symptoms all suggest secondary hyperhidrosis and need investigation by your GP first.

Sweat glands are activated by nerve signals using a chemical messenger called acetylcholine. Botulinum toxin temporarily blocks the release of acetylcholine at the nerve endings supplying the sweat glands. With the signal blocked, the sweat glands stop producing sweat. The effect is reversible and lasts 6–9 months for axillary treatment.

Benefits of Anti Sweat Injections

For patients with primary axillary hyperhidrosis, anti sweat injections produce one of the most dramatic quality-of-life improvements available from any non-surgical aesthetic treatment.

Most patients experience 80–100% reduction in underarm sweating in the treated zones. Many describe their underarms as "completely dry" for the first time since adolescence. Clothing remains unmarked through normal daily activity, including in stressful situations and warm weather.

Effects typically last 6–9 months for axillary treatment — significantly longer than for muscle treatment because sweat-gland nerves regenerate more slowly than motor nerves. Some patients have effects lasting 12+ months. Most patients have 1–2 sessions per year.

Underarm odour comes from bacterial breakdown of sweat. With less sweat, bacterial activity reduces and underarm odour reduces or stops. Many patients find they no longer need strong antiperspirants or deodorants.

For axillary use, this is a licensed, evidence-based, well-studied treatment with extensive published efficacy and safety data. It’s not an off-licence aesthetic application — it’s an established medical treatment for a recognised medical condition.

Who is Suitable for Anti Sweat Injections? Comparison vs Other Treatments

Anti sweat injections are suitable for adults aged 18+ with primary hyperhidrosis (most commonly axillary) where antiperspirant treatment hasn’t worked. Suitability is confirmed at face-to-face consultation with the plastic surgeon.

A face-to-face consultation with the plastic surgeon is required. The mandatory two-week cooling-off period applies — you book consultation, then book treatment minimum 14 days later.

Preparing for Anti Sweat Injections

Good preparation reduces bruising risk and improves outcomes. The plastic surgeon will give you specific instructions at consultation.

The Anti Sweat Injection Procedure

The injection itself takes 10–15 minutes for both underarms. Allow 45–60 minutes total for the appointment including consultation review, sweating-zone mapping, photographs, numbing cream application (if requested), and aftercare advice.

Each injection is a brief pinprick. The underarm skin has relatively few sensitive nerve endings so the experience is generally less uncomfortable than facial treatment. With topical numbing cream applied, most patients describe the discomfort as 2–3 out of 10. Without numbing, slightly more — typically 3–4 out of 10. The whole treatment for both underarms takes 10–15 minutes.

A follow-up review is included in the treatment cost. At this review:

Aftercare After Anti Sweat Injections

Recovery in summary: Minimal downtime. Resume work and most normal activities the same day. Avoid lying flat, heavy exercise, and underarm massage for 4 hours. Avoid alcohol for 24 hours. No deodorant or shaving for 24 hours. Effects start to appear from day 3–7; full effect by 2–3 weeks.

Beyond Injections — Surgical Options for Long-Term Sweat Reduction

For patients who respond well to anti sweat injections but want a longer-lasting solution, surgical options exist. This section explains when each is appropriate and when to consider escalating beyond injection treatment.

is a minor surgical procedure performed under local anaesthetic at our Baker Street clinic. The plastic surgeon makes small incisions in the underarm crease and uses a fine cannula to physically remove a high proportion of the sweat glands from the underarm tissue. The result is significant long-term reduction in sweating — typically 70–90% reduction sustained for years.

Trade-offs of surgical curettage compared to injections:

The page URL on our site references "laser hyperhidrosis treatment" — this is historical naming. Our current surgical hyperhidrosis treatment uses suction curettage rather than laser-based devices. We’ve found surgical curettage gives more reliable long-term reduction than laser approaches.

RF microneedling treatment can produce some reduction in axillary sweating by thermally treating the sweat gland layer. The reduction is typically partial (30–50%) rather than the dramatic reduction from injections or surgery, and the effect is gradual over 3–4 sessions. We don’t currently consider this a first-line option for severe hyperhidrosis — patients with significant symptoms typically do better with injections or surgical curettage.

ETS is a more major surgical option historically used for severe palmar (palm) hyperhidrosis where everything else has failed. It involves division of sympathetic nerves in the chest. The treatment is highly effective for palms but has a significant rate of compensatory sweating elsewhere on the body — sometimes severe. We don’t perform ETS at Centre for Surgery and refer to specialist thoracic colleagues only in carefully selected cases.

It’s common to combine approaches. Examples:

The plastic surgeon will discuss the right approach for your specific symptom severity and treatment goals at consultation.

Risks and Side Effects of Anti Sweat Injections

Anti sweat injections are well-established and considered low-risk when performed by appropriately trained clinicians. Most adverse effects are mild and temporary. The treatment has decades of safety data both for the licensed axillary indication and for off-licence palmar/plantar use.

The treatment is not appropriate for:

Most adverse outcomes from anti sweat injections relate to incomplete coverage (some active sweat glands missed, leading to patchy results) rather than serious complications. Surgeon-level mapping using Minor’s iodine-starch test ensures full coverage of the active zone. For palmar treatment specifically, surgeon-level anatomical knowledge of underlying small hand muscles minimises the risk of grip weakness.

Anti Sweat Injection Cost in London — Plastic Surgeon-Led Pricing

Anti sweat injections at Centre for Surgery are £950 for both underarms treated together. Pricing reflects the GMC Specialist Register plastic surgeon credential and sits above standard nurse-injector tier in the London market.

Every quote at Centre for Surgery includes:

There are no hidden charges. The price quoted at consultation is the price you pay.

Most London anti sweat injections are delivered by aesthetic nurses at £350–£600 per session. Plastic-surgeon-led clinics sit at a different pricing tier because the credential, training time, and accumulated anatomical experience are significantly higher. For axillary treatment, the difference is most relevant in cases of incomplete previous treatment, very severe hyperhidrosis, or when the patient is also considering surgical curettage as a step-up. For palmar treatment, surgeon-level knowledge of underlying hand muscle anatomy is the primary safety differentiator.

For comparison: most patients with significant hyperhidrosis spend £100–£300 per year on prescription antiperspirants, replace clothing damaged by sweat and antiperspirant marks, and pay for repeated dry-cleaning of stained items. Single-session injection treatment at £950 lasts 6–9 months and typically eliminates these ongoing costs.

For patients budgeting over multiple years:

Patients who know botulinum toxin works for them and want a longer-lasting solution often consider surgical curettage as a sensible escalation after 2–3 successful injection cycles.

NHS provision exists in some areas via dermatology referral for severe primary axillary hyperhidrosis where prescription antiperspirants have failed — waiting times can be lengthy. Private health insurance may cover treatment depending on policy and prior authorisation. We can provide medical documentation to support insurance claims.

Why Choose Centre for Surgery for Anti Sweat Injections

Hyperhidrosis treatment is sometimes described as a routine procedure. It’s not, particularly when patients have significant disease burden, when previous treatment elsewhere has been incomplete, or when patients are considering escalation to surgical options. Here’s why patients choose Centre for Surgery.

Every injectable treatment at Centre for Surgery is performed by a plastic surgeon on the GMC Specialist Register — the same surgeon who would perform your suction curettage if you escalated to surgical treatment. This level of credential is uncommon for hyperhidrosis treatment in London, where most injections are delivered by aesthetic nurses. Surgeon-level anatomical knowledge is the primary safety mitigation, particularly for palmar treatment near hand muscles.

We offer the complete range of hyperhidrosis treatment options — from anti sweat injections through to surgical suction curettage. Most patients start with injections, see how they respond, and have the option to escalate to surgical treatment with the same clinical team if they want longer-lasting results. There’s no need to switch clinics or coordinate multiple practitioners.

Centre for Surgery is a private clinic on Baker Street, London. The same clinical governance standards required of any private hospital apply at our clinic.

We tell you directly if your sweating pattern suggests secondary hyperhidrosis (caused by an underlying medical condition) rather than primary hyperhidrosis. Whole-body sweating, night sweats, weight changes, fevers, or sudden adult onset all warrant medical investigation rather than direct toxin treatment. We don’t recommend treatment that won’t address the underlying problem.

We use the Minor’s iodine-starch test to map the active sweating zone precisely before injection. This ensures full coverage of all active sweat glands and avoids the patchy results that can occur with visual estimation alone. The test is included in the treatment cost.

The 4–6 week follow-up review is included. If any active sweating zones remain at review, we add a free top-up at that point. The reasoning is simple: full coverage matters, and we want to deliver complete reduction rather than partial.

For patients who respond well to injections but want longer-lasting results, our suction curettage service is available with the same plastic surgeon team. Many patients use injections for 2–3 cycles to confirm botulinum toxin works for them, then escalate to surgery for the long-term solution.
