Hyperhidrosis of the Armpits

Botox as a treatment that to help control the symptoms of severe underarm sweating

If you have hyperhidrosis of the armpits, you’re likely all too familiar with the emotional and physical toll this condition can take on your life. From constantly worrying about visible sweat stains to feeling self-conscious in social situations, hyperhidrosis can be a challenging and frustrating problem to manage. However, a potential solution may provide long-lasting relief: botulinum toxin injections.

Understanding Hyperhidrosis


Hyperhidrosis is a medical condition characterised by excessive sweating that goes beyond what is necessary for the body to regulate its temperature. This excessive sweating can be triggered by factors such as heat, stress, or even no apparent reason at all.

There are two types of hyperhidrosis: primary and secondary. Primary hyperhidrosis is usually localised to specific body areas, such as the armpits, palms, or feet. In contrast, secondary hyperhidrosis is caused by an underlying medical condition or medication side effect and typically affects the entire body.

According to the International Hyperhidrosis Society, about 2.8% of the population suffers from hyperhidrosis, meaning millions worldwide are dealing with this condition.

Treating Hyperhidrosis with Botulinum Toxin Injections


Botulinum toxin, more commonly known as Botox, is a neurotoxin derived from the bacterium Clostridium botulinum. While it’s best known for its cosmetic uses in reducing wrinkles and facial lines, botulinum toxin has also been approved for treating various medical conditions, including hyperhidrosis.

When injected into the skin, botulinum toxin blocks the release of acetylcholine, a neurotransmitter that stimulates sweat glands. By preventing this release, the sweat glands become temporarily inactive, significantly reducing sweating.

Several studies have shown that botulinum toxin injections are highly effective in treating armpit hyperhidrosis, with up to 90% success rates. Many patients undergoing botulinum toxin injections for armpit hyperhidrosis report a significantly improved quality of life. They often describe newfound confidence, freedom in social situations, and the ability to wear clothing without fear of visible sweat stains.

Frequently Asked Questions

If you’re considering botulinum toxin injections for your armpit hyperhidrosis, here’s a general overview of the process:

  1. Consultation: First, you’ll meet Dr Bong who is experienced in administering botulinum toxin injections for hyperhidrosis. He will evaluate the severity of your condition, discuss your medical history, and determine if you’re a suitable candidate for the treatment.
  2. Preparing for the treatment: Before the procedure, you may be asked you to shave your armpits and avoid using antiperspirants or deodorants. You should also inform Dr Bong of any medications or supplements you’re currently taking.
  3. The injection process: During the procedure, a small amount of botulinum toxin will be injected into several points in each armpit, targeting the areas with the highest concentration of sweat glands. The process is relatively quick and may cause mild discomfort, but most patients tolerate it well.
  4. Post-treatment care and expectations: After the injections, you should avoid strenuous activity and excessive heat exposure for a few days. You may notice a reduction in sweating within a week, but it can take up to two weeks for the full effects to become apparent. The results usually last between four and twelve months, after which you may need to repeat the treatment.

As with any medical procedure, there are potential risks associated with botulinum toxin injections for hyperhidrosis. Some of the possible side effects include:

  • Pain or bruising at the injection site
  • Muscle weakness or stiffness in the treated area
  • Headaches
  • Flu-like symptoms

These side effects are generally mild and temporary, but please do discuss any concerns you may have with Dr Bong before undergoing the treatment.

If you are not attending the Essence Medical Clinic, to ensure your safety and minimise risks, it’s crucial to choose a qualified and experienced medical professional for your injections. Be sure to discuss your medical history and any medications or supplements you’re taking, as certain conditions or medications may increase the risk of complications.

The effects of botulinum toxin injections for armpit hyperhidrosis typically last between four and twelve months. However, individual results may vary, and some patients may require more frequent treatments.

If you are a new patient, a booking fee will be taken at the point of making your appointment.  Please read our full terms and conditions here.

We respect that your time is valuable, and we appreciate that you understand ours is too. Unfortunately, if appointments are cancelled or rescheduled at short notice, or if you do not attend an appointment, we cannot allocate your appointment slot to someone else; however, we still have overheads and staff salaries to pay. Please read our full terms and conditions here.

Please note for all patients, a £50 fee will be charged if you cancel or reschedule ANY appointment (including appointments which do not require an upfront deposit, such as a ‘check-up’ or review appointment) less than 48 hours before the appointment time. Patients who have pre-purchased a course of treatment will forfeit one of the treatments instead of paying this fee.

Late arrival to your appointment may result in reduced treatment time or the forfeiting of the appointment. We will endeavour to ensure that your appointment runs on time.

To help our patients minimise the chance of losing their deposit or pre-paid treatments, we issue text reminders a minimum of 48 hours ahead of appointments. Patients should be aware that there may be reasons beyond our control, meaning that the text message does not reach them. Patients should diarise themselves when making follow-up appointments and not rely solely on the text message from the clinic as a reminder.

I had Botox in my armpits to prevent excessive sweating, and it has been the best decision I've made. My sweating has not yet returned to normal, allowing me to confidently wear anything without worrying about sweat marks. Thank you Dr Bong, I am so pleased.

I was so unsure about whether to invest in this until a friend recommended me to Dr Bong. I can't tell you how pleased I am - no more embarrassing sweat marks for me!
