London in the summer has its own rhythm. Packed Tube carriages, crowded pavements, long evenings that drift into rooftop drinks or outdoor events. It should feel energising, but for those dealing with excessive sweating, it often becomes something to manage rather than enjoy.
At Aesthetics Lab, we often see patients who have quietly adjusted their routines around sweating. Dark clothing, avoiding certain fabrics, planning journeys to minimise stress or heat. Many assume it is just something they have to live with. In reality, there is a highly effective medical treatment that can offer months of relief.
In this blog, we explore how wrinkle-relaxing injections are used to treat excessive sweating, what to expect from treatment, and how we approach it in clinic.
Why does excessive sweating happen?
Excessive sweating, or hyperhidrosis, is more than simply “sweating a lot”. It is caused by overactive signals from the nervous system to the sweat glands, even when the body does not need cooling.
The most commonly affected areas are:
- Underarms
- Palms of the hands
- Soles of the feet
- Forehead and scalp
For some patients, it is constant. For others, it flares in response to stress, heat, or social situations. While factors like heat and anxiety can worsen symptoms, the underlying issue is neurological. That is why topical products often fall short.
How do wrinkle-relaxing injections reduce sweating?
Wrinkle-relaxing injections are widely known for softening lines, but in clinic they are just as valuable for treating hyperhidrosis.
They work by temporarily blocking the chemical signals between nerves and sweat glands. Without that signal, the gland simply does not activate.
The effect is localised and controlled. Only the treated area is affected, meaning the body continues to regulate temperature normally elsewhere.
What areas can be treated?
Underarm sweating (axillary hyperhidrosis)
This is by far the most common concern we treat. It tends to respond very predictably to wrinkle-relaxing injections.
Patients often describe:
- Clothing no longer becoming damp during the day
- Increased confidence in professional and social settings
- Less reliance on strong antiperspirants
From a clinical perspective, the underarms are straightforward to treat and typically require a single session every 4 to 6 months.
Sweaty hands and feet
Treating palms and soles is more nuanced. These areas are more sensitive and require careful technique.
In clinic we would usually:
- Assess severity and impact on daily life
- Adjust dosing and placement accordingly
- Discuss comfort measures during treatment
Results can be excellent, but expectations need to be managed. These areas may require slightly more frequent maintenance.
Forehead sweating
Forehead sweating is often overlooked but can be particularly frustrating, especially during commuting or events.
Wrinkle-relaxing injections can:
- Reduce visible perspiration
- Improve makeup longevity
- Maintain a natural appearance when carefully administered
This is an area where clinical experience matters. The aim is always to balance sweat reduction without affecting natural expression.
What is the treatment process like?
The procedure itself is relatively quick and precise.
A typical appointment involves:
- A detailed consultation to assess the pattern and severity of sweating
- Marking the treatment area to ensure even coverage
- Administering small, targeted injections just beneath the skin
Most patients describe the sensation as mild and manageable. For more sensitive areas, we can use topical numbing.
There is no significant downtime. You can return to normal activities the same day, although we usually advise avoiding intense exercise or heat exposure for 24 hours.
How long do the results last?
Results typically begin within 5 to 10 days, with full effect at around two weeks. Most patients enjoy:
- 4 to 6 months of reduced sweating
- Gradual return of normal sweating over time
In clinic we often find that repeat treatments can feel even more effective, as patients become familiar with the process and timing.
Who is this treatment suitable for?
Wrinkle-relaxing injections for excessive sweating are suitable for a wide range of patients.
You may benefit if:
- Antiperspirants and topical treatments have not worked
- Sweating interferes with daily life or confidence
- You avoid certain clothing or situations due to sweating
For milder cases we would usually start with topical or prescription options. If that is not settling, we would normally look at injectable treatment as the next step.
What are the benefits beyond staying dry?
While the physical reduction in sweating is significant, the wider impact is often what patients value most.
In clinic, patients frequently report:
- Increased confidence in work environments
- Greater ease in social situations
- Freedom to wear lighter or more varied clothing
- Reduced anxiety linked to sweating
What stands out is how quickly patients adapt. Many realise how much mental energy they were previously dedicating to managing sweating.
Is it safe?
When performed by experienced practitioners, wrinkle-relaxing injections are a safe and well-established treatment for hyperhidrosis.
We take a conservative, medically-led approach:
- Thorough consultation and assessment
- Precise dosing tailored to the individual
- Ongoing review and adjustment if needed
Side effects are generally mild and temporary, such as slight redness or swelling at injection sites.
Living in London with hyperhidrosis
There is something very specific about navigating London in the heat. The combination of crowded transport, fast-paced schedules, and social expectations can make excessive sweating feel more pronounced.
Patients visiting our clinics in Belgravia and Primrose Hill often describe the same pattern. Avoiding the Central line at peak times, carrying deodorant, perfume and even spare clothing and planning routes around comfort.
Treatment does not change the city, but it changes how you experience it. The difference between enduring the heat and moving through it comfortably is often what brings patients to seek help.
Frequently Asked Questions
How effective are wrinkle-relaxing injections for excessive sweating?
They are considered one of the most effective treatments available, particularly for underarm sweating, with high patient satisfaction rates.
Does the treatment stop sweating completely?
It significantly reduces sweating in the treated area, but does not completely eliminate the body’s ability to regulate temperature.
Is the treatment painful?
Most patients find it very tolerable. For sensitive areas, numbing options are available to improve comfort.
How often will I need treatment?
Typically every 4 to 6 months, depending on how your body responds and the area treated.
Will sweating increase elsewhere?
This is very uncommon. The body continues to sweat normally in untreated areas.
Can I have treatment before a holiday or event?
Yes, but timing is important. We usually recommend having treatment at least 2 weeks beforehand to allow full results to develop.
Book a consultation
Excessive sweating can impact daily life more significantly than many realise. When simple measures are no longer effective, it is worth exploring medical options that are both safe and reliable.
At Aesthetics Lab, we take a personalised approach to excessive sweating treatment using wrinkle-relaxing injections. Each treatment plan is carefully tailored based on the area affected, the severity of symptoms, and how it fits into your day-to-day routine. Our level of detail makes a meaningful difference to both results and overall satisfaction.
For those living in London, or regularly commuting into the city, treatment can genuinely change how the warmer months feel. Whether it is navigating the Tube, attending meetings, or enjoying social events, many patients notice a shift from managing symptoms to simply getting on with their day.
If you are considering treatment, book a consultation at one of our clinics in Belgravia or Primrose Hill. We will assess your concerns in detail, talk through your options, and advise whether wrinkle-relaxing injections are the most appropriate choice for you.
