Hyperhidrosis Treatment · Kensington, London
Excessive Sweating Treatment in London for Underarms, Hands and Feet
Excessive sweating treatment reduces sweating at one site of the body — usually an underarm, a palm or a sole — through a series of small injections placed just under the skin. Sweating heavier than the body needs for temperature control has a medical name, hyperhidrosis, and more than one cause, so every case is examined face to face by Dr Prasad, a GMC-registered doctor, before treatment is planned. Hyperhidrosis treatment is available at Faciem Dermatology & Medical Clinic on Kensington Church St, London, where Dr Prasad assesses, prescribes and injects.
The medicine used is prescription-only, which means it cannot be supplied to anyone who has not been seen and examined in person. That consultation settles which areas suit treatment, what the alternatives are, and what the price will be in writing.

TL;DR
Excessive sweating treatment reduces sweating at a treated site — most often an underarm, palm or sole — using a series of small injections placed just under the skin. At Faciem it follows a face-to-face consultation with Dr Prasad, a GMC-registered doctor with 20 years’ experience, and prices start from £450. The appointment runs to about 45 to 60 minutes, the effect begins at around 72 hours, and for most people it holds for 3 to 5 months before fading. Patients and clinical studies have reported improvements of around 80 to 90% at the treated site, though the degree of change and how long it lasts are not the same for everyone.

About the Treatment
What Is Excessive Sweating Treatment and How Does It Work?
How the injections quieten sweating at one site, what the appointment involves, and why the type of hyperhidrosis is established before anything is treated.
Excessive sweating treatment interrupts the nerve signal that tells sweat glands in one area to produce sweat. A series of small injections is placed just beneath the skin across that area — commonly an underarm, palm or sole — so sweating there reduces while sweating elsewhere carries on normally. Hyperhidrosis is the medical term for sweating heavier than the body needs to control its temperature. The effect of treatment is temporary and usually holds for 3 to 5 months.
How do the injections reduce sweating?
Sweat glands do not switch themselves on. Small nerve endings release a chemical messenger that tells them to work, and it is that message the treatment interrupts. Botulinum toxin, a prescription-only medicine, is placed in tiny quantities just under the surface of the skin so the messenger no longer reaches the glands across the treated site.
The glands are neither removed nor destroyed. They simply stop receiving the instruction to produce sweat, which is why the effect is temporary and fades as the nerve endings recover. Patients and clinical studies have reported improvements of around 80 to 90% at the site treated, though response differs from person to person and no outcome can be promised in advance. Because the medicine acts only where it is placed, sweating on the rest of the body is unaffected and the body keeps its overall ability to regulate temperature.
Primary or secondary: why the type of sweating is established first
Excessive sweating is not a single condition. Primary focal hyperhidrosis usually starts in childhood or the teenage years, affects particular sites such as both underarms, both palms or both soles, often runs in families, and typically settles during sleep. Secondary hyperhidrosis is sweating driven by something else — a thyroid disorder, diabetes, an infection, the menopause, anxiety, or a medicine already being taken — and more often affects the body as a whole.
The distinction changes what should happen next. Sweating that begins suddenly in adult life, occurs mainly at night, affects one side of the body only, or arrives alongside weight loss, fever or feeling generally unwell warrants medical investigation before any cosmetic appointment. Dr Prasad takes a full history at the consultation and says openly when investigation, not injections, is the sensible next step — a private doctor appointment is often the better place to start in that case.
What the appointment involves, and how it feels
The appointment is unhurried and follows the same order each time. The area is cleaned, numbing cream is applied and left to work, sometimes under cling film, then removed before treatment starts. A series of small injections is placed just underneath the skin, spaced across the area so the whole of it is covered. Allow around 45 to 60 minutes, including the time the numbing cream needs.
Most people describe the sensation as a run of brief scratches, not a sharp pain. Palms and soles are more sensitive than underarms, so comfort measures are agreed in advance and the pace is yours to set. Sensitivity varies considerably, and saying so during the appointment changes how it is done.
The medicine used, and why it is prescription-only
The medicine used to reduce sweating is botulinum toxin, which in the United Kingdom is classified as a prescription-only medicine. That classification has practical consequences. It cannot be advertised to the public, it cannot be sold as an offer or an incentive, and it cannot be prescribed for you without a face-to-face consultation with a prescriber who has examined you. At Faciem that prescriber is Dr Prasad, who assesses, prescribes and injects, with none of those steps handed to someone else.
Several licensed brands are available in the UK and they are not interchangeable dose for dose. Which one is used for your treatment, and the indication it is licensed for, is confirmed at your consultation. You are entitled to be told its name and to have it recorded in your notes, and if that is not offered, ask.
The alternatives to injections
Injections are not the only approach to excessive sweating and they are not always the first one. Where sweating affects the whole body, prescription medication may be the more appropriate route, and its advantages and drawbacks are put to you in full. Where the underarms, hands or feet are the problem, iontophoresis is another option offered at the clinic. Every option is discussed in line with the General Medical Council’s Good Medical Practice, which is the standard Dr Prasad works to as a registered doctor.
Faciem also offers a micro-channelling infusion, in which low doses of botulinum toxin are placed very superficially across the face, forehead and palms; many people find it gives considerable relief through the hot summer months. The same medicine is used at different doses and depths for anti-wrinkle injections for facial lines, which is a separate treatment with separate aims and its own assessment.
Where Sweating Is Treated
Areas Treated for Excessive Sweating
Excessive sweating treatment is directed at the sites where sweating is most disruptive, not at the whole body. Underarms, palms and soles are treated most often, with the face, the area under the breasts and the groin treated in selected cases. Which areas suit treatment is decided at consultation, once the pattern of sweating is clear.
ZONE I
Most commonly treated
The sites where focal sweating interferes most with work, clothing and daily life.
Underarms
Sweat that soaks through shirts and marks clothing is the most frequent reason people ask about treatment. Underarms are also the least sensitive of the commonly treated sites.
Palms of the hands
Damp palms affect handshakes, paperwork, keyboards and grip. The palms feel injections more keenly than the underarms, so comfort is planned in advance.
Soles of the feet
Sweating soles can make footwear slip and leave skin softened and sore. Suitability and comfort are assessed individually before treatment is agreed.
Face and forehead
Facial sweating and a persistently damp hairline are treated in selected cases, and Faciem’s micro-channelling infusion places low doses very superficially across this area. Flushing with visible redness is more often rosacea, a separate condition, which is assessed on its own terms.
ZONE II
Treated less often
Sites treated in selected cases, where sweating is confined and troublesome.
Under the breasts
Sweating in this fold can leave skin sore and prone to irritation. Whether treatment is appropriate depends on what the examination shows.
Groin
Sweating in the groin is treated in selected cases only, and any rash or skin change in the area is assessed before treatment, not after.
ZONE III
Approaches discussed
What may be recommended once the pattern and cause of the sweating are clear.
Injections for focal sweating
Small injections of botulinum toxin, a prescription-only medicine, placed just under the skin across the affected site. Usually planned as a single treatment.
Micro-channelling infusion
Low doses placed very superficially across the face, forehead and palms, which many people find gives relief through the hot summer months.
Iontophoresis
A treatment offered for sweating of the armpits, hands or feet, using a weak electrical current passed through water instead of injections.
Prescription medication
Where sweating affects the whole body, the advantages and drawbacks of prescription medication are discussed as part of setting out every option.
Choosing the Right Treatment
Sweating Injections vs Iontophoresis: What’s the Difference?
Both approaches are offered at Faciem for sweating of the underarms, hands and feet, and neither is automatically the better one. Injections act on the nerve signal reaching the sweat glands and are usually planned as a single appointment. Iontophoresis works at the skin surface and is repeated over a course. Which suits you depends on the sites affected, how you feel about needles, and how much time you can commit.
| Injections for focal sweating | Iontophoresis | |
|---|---|---|
| How it works | Small injections just beneath the skin block the nerve signal that switches on the sweat glands in the treated area. | A weak electrical current is passed through water to the hands or feet. The mechanism is not fully established, but sweating reduces with repeated use. |
| Best for | Focal sweating of the underarms, palms and soles, and selected other sites. | Sweating of the armpits, hands or feet, particularly where injections are not wanted. |
| Results appear | From around 72 hours after treatment. | Gradually, across a course of sessions instead of after a single visit. The schedule and the interval between sessions are set out at your consultation. |
| Results last | One treatment usually holds for 3 to 5 months before the effect fades. The point at which it wears off is individual and is discussed at consultation. | Held by continuing to repeat sessions; there is no single course that ends the need for them. |
| Downtime | Usually minimal; redness, bruising or swelling can occur at the injection sites. | None expected, as nothing is injected and the skin surface is not broken. |
| Ideal candidate | Someone with sweating confined to one or two sites who would prefer to deal with it in a single appointment. | Someone who would prefer to avoid needles and can commit to attending repeated sessions. |
Neither approach suits everyone, and how well either works is individual. Where the assessment points to a secondary cause, or to prescription medication for generalised sweating, Dr Prasad says so — including when the honest answer is that neither option in this table is the right one for you.
Transparent Pricing
How Much Does Excessive Sweating Treatment Cost at Faciem?
Excessive sweating treatment at Faciem starts from £450. What you actually pay depends on how many areas are treated and how much medicine that requires, which is why a figure quoted over the phone before anyone has examined you can only ever be an estimate. The price that applies to you is set out in writing at your consultation, before anything is agreed.
Prices for injectable treatment across London vary far more than most patients expect, and the lowest quote is seldom comparing like with like. Ask which medicine is used, how much of it the price includes, who is prescribing and injecting it, and what happens if you need to be seen again afterwards. A price that cannot answer those questions is not a price you can compare.
We would rather you chose carefully than quickly. If the assessment suggests injections are not the right answer — because the sweating is generalised, or because it needs investigating first — Dr Prasad will tell you, and you will not be charged for a treatment you do not go on to have.
| Treatment | Price |

| Excessive sweating treatment, one area | From £450 |
| Additional area at the same appointment | Confirmed at consultation |
| Micro-channelling infusion | Confirmed at consultation |

Experience & Expertise
Why Who Treats Your Sweating Matters
Reducing sweating in an underarm, a palm or a sole is not a matter of injecting one spot. The medicine acts only where it is placed, so coverage depends on how the injections are spaced across the area and how deeply they sit. Too shallow or too widely spaced and patches of sweating remain; too deep in the palm and the small muscles that control grip can be affected temporarily. Dr Prasad plans the pattern for the site being treated and injects it herself.
The other half of the skill is knowing when not to inject. Sweating that has started suddenly, that happens at night, or that affects the whole body may point to a condition needing a diagnosis, not a site needing treatment. Dr Prasad is a GMC-registered doctor with 20 years’ experience in dermatology and medical aesthetics, and will discuss investigation or referral where the history calls for it. Her training, registration and clinical background are set out on her profile page.

Patient Reviews
Rated Excellent by Patients on Google
Your Journey, Our Promise
What Happens, Step by Step
Four stages, from the first consultation to the review once the effect has settled — and the points along the way where you can stop and think before anything is agreed.
STEP 01
Consultation
Dr Prasad asks when the sweating started, which sites it affects, whether it wakes you at night and what medicines you take, then examines the areas involved. This is the appointment at which primary and secondary hyperhidrosis are told apart, and at which investigation is raised if the history points that way.
STEP 02
Personalised plan
You are told which sites are suitable for injection, which are better served by iontophoresis or prescription medication, and what the treatment costs, in writing. A prescription-only medicine cannot be prescribed without this step. Going away to think it over is expected, not discouraged.
STEP 03
Treatment
The site is cleaned and numbing cream applied, then removed once it has worked. Small injections are spaced just under the skin so the whole area is covered — an underarm takes less time than a palm or a sole. The appointment runs to around 45 to 60 minutes in total.
STEP 04
Aftercare & review
You leave with written aftercare and a point of contact if anything concerns you. The first 24 hours are the ones with restrictions on heat, exercise and pressure; sweating then starts to reduce at around 72 hours and keeps reducing over the following one to two weeks. A review is arranged once the effect has settled, so any patch still sweating can be looked at. The timing of that review, and whether a charge applies, is confirmed at your consultation.
Side Effects & Safety
What Are the Risks and Side Effects?
Excessive sweating treatment carries side effects, and how likely they are depends heavily on who assesses you and where the medicine is placed. Most effects reported after treatment are local, temporary and related to the injections themselves. Everything below is discussed with you before you consent, not afterwards.
Common, temporary effects
- Redness at the injection sites, usually settling within hours
- Bruising, which is more visible on thin skin and can last a few days
- Swelling or tenderness across the treated area
- Discomfort during the injections, particularly on the palms and soles
Uncommon effects
- Less commonly, people report headache, or a feeling of mild weakness in the small muscles of the hand after palm treatment, which can affect fine grip. Effects of this kind are temporary and ease as the medicine wears off. Occasionally an area is missed and continues to sweat, which is one reason a review appointment is arranged. Any effect that worries you should be reported to the clinic, not waited out.
Who this treatment is not for
- Treatment is not offered during pregnancy or breastfeeding, where there is a neuromuscular condition such as myasthenia gravis, where there is infection or active skin disease at the injection site, or where you have reacted to botulinum toxin before. Sweating that began suddenly, occurs at night or affects the whole body needs investigating first. Suitability is confirmed individually at consultation.
After Your Treatment
Looking After Treated Areas
Aftercare following excessive sweating treatment covers the first 24 hours, and the arc after that is worth knowing in advance. Stay upright for 4 hours and keep heat and hard exercise away from the site for 24 hours; deodorant, antiperspirant and normal washing can go back to usual after that first day. Sweating then begins to reduce at around 72 hours and the effect keeps building over the first one to two weeks, which is the point at which the result is fairly judged.
Do
- Keep the treated area clean and dry for the first 24 hours
- Stay upright for at least 4 hours after treatment
- Carry on with light daily activity, and expect to be back at work the same day or the day after
- Use a cool compress for 5 to 10 minutes at a time if an injection site feels tender
- Contact the clinic if anything you were not expecting develops in the first 48 hours, or sooner if it worries you
Avoid
- Strenuous exercise, gym sessions and hot yoga for 24 hours
- Saunas, steam rooms, sunbeds and very hot baths for 24 hours
- Rubbing, massaging or scrubbing the treated area for 24 hours
- Deodorant, antiperspirant, and tight clothing or footwear pressing on the site, for 24 hours
- Alcohol for 24 hours either side of treatment, which can make bruising more obvious
This is general guidance and does not replace the personalised advice you are given on the day, which takes account of the sites treated and your own medical history. The written sheet you are handed at the clinic is the version to follow. A patch that is still sweating two weeks after treatment is worth raising at the review rather than waiting it out.
Common Questions
Your Questions, Answered
Cost, comfort, how quickly it works, when you can train or get back to work, and what happens when it wears off — the things people ring the clinic to ask about excessive sweating. Anything not covered here can be raised at your consultation.
How much does excessive sweating treatment cost in London?
At Faciem, excessive sweating treatment starts from £450. The final figure depends on how many areas are treated and how much medicine that takes, so it is confirmed in writing at your consultation and not quoted over the phone. Prices across London vary widely, and what is included in them varies just as much.
Does treatment for excessive sweating hurt?
Most people describe a run of brief scratches, not sharp pain. Numbing cream is applied to the area first and removed before the injections begin. Palms and soles are more sensitive than underarms, so comfort measures for those sites are agreed in advance. How much you feel differs from one person to the next.
How long does excessive sweating treatment take to work?
The effect usually starts at around 72 hours after treatment, not on the day. Sweating in the treated area then reduces gradually over the following days in most people. A review appointment is arranged once the effect has settled, so any patch still sweating can be identified and discussed.
How long do the results last?
For most people the effect of excessive sweating treatment lasts 3 to 5 months. It fades as the nerve endings recover, at which point treatment can be repeated. Duration is not the same for everyone, so where you fall in that range is discussed at your consultation and the repeat appointment is planned around the point at which it wears off for you.
Who is not suitable for excessive sweating treatment?
Treatment is not offered during pregnancy or breastfeeding, where there is a neuromuscular condition such as myasthenia gravis, where there is infection or active skin disease at the injection site, or where you have reacted to botulinum toxin before. Faciem treats adults. Sweating that suggests an underlying cause is investigated before anything is treated, and suitability is settled at a face-to-face consultation.
What causes excessive sweating?
Primary focal hyperhidrosis has no underlying illness behind it: the nerves supplying certain sweat glands are simply overactive, often from childhood, and it frequently runs in families. Secondary hyperhidrosis is caused by something else, such as a thyroid disorder, diabetes, infection, the menopause or a medicine you are taking. The two are managed differently, which is why the type is established first.
When should sweating be checked by a doctor before it is treated?
See a doctor first if sweating has started suddenly in adult life, happens mainly at night, affects one side of the body only, or comes with weight loss, fever or feeling unwell. Patterns of that kind can point to an underlying condition. Investigation, often at a private doctor appointment, comes before any cosmetic treatment.
How many sessions of excessive sweating treatment will I need?
Excessive sweating treatment is usually planned as one treatment, not a course. The effect wears off after 3 to 5 months in most people, so those who find it helpful tend to come back when the sweating does. How often that turns out to be is discussed at your review.
Can I exercise after excessive sweating treatment?
Leave 24 hours before strenuous exercise, gym sessions or hot yoga. Light activity and walking are fine straight away, so there is no need to write off the day. The 24-hour gap simply keeps heat, heavy sweating and pressure away from the injection sites while they settle. From the following day, training goes back to normal, and once the effect starts at around 72 hours the treated area sweats less during it.
How much does the treatment actually reduce sweating?
Patients and clinical studies have reported improvements of around 80 to 90% in the area treated. That is a reported range, not a promise: some people notice a bigger change and some less, and a patch that has been missed can usually be identified at the review appointment. Sweating outside the treated area is not affected.
Can excessive sweating be treated on the hands and feet, not just the underarms?
Yes. Palms and soles are both treated, alongside underarms, and in selected cases the face, the area under the breasts and the groin. Palms and soles are more sensitive than underarms, so they are discussed separately at consultation, including what the treatment involves, how it feels and what to expect afterwards.
How soon can I go back to work or to an event after treatment?
Most people go back to work the same day as excessive sweating treatment or the day after, as downtime is usually minimal. Redness at the injection sites tends to settle within hours, though bruising can show for a few days. An event needs different timing from a working day: sweating only begins to reduce at around 72 hours and keeps improving over the first one to two weeks, so book at least two weeks before a wedding, holiday or presentation you want it to help with.
Excessive Sweating Treatment in Kensington, London
A Doctor-Led Clinic in the Heart of Kensington
Faciem Dermatology & Medical Clinic sits on Kensington Church St, the road that runs between High Street Kensington and Notting Hill Gate stations — a few minutes on foot from one, about ten from the other. Most people who come for sweating treatment travel in from West and Central London, and there is a Kensington council underground car park close by for anyone who would prefer to drive.
Excessive sweating is something people tend to want handled discreetly and without taking a day off work. The clinic is open Monday to Saturday, 10am–7pm, so an appointment can sit at the start or the end of a working day, and most people go back to work the same day or the day after.
Before booking sweating treatment anywhere, ask four questions. Who will examine you, and will that happen face to face before a prescription is written? Are they registered with the GMC, NMC or GDC? Which licensed medicine is being used, and will its name go in your notes? And what does the quoted price cover if you need seeing again? A clinic that cannot answer all four is not one to hand a card to.
There is no obligation to go ahead after a consultation, and no pressure to decide on the day. If the sweating turns out to need investigating before it is treated, you will be told so plainly. You can put a question to the clinic first if you would prefer not to book straight away, or look through the full range of treatments offered at Faciem.
