A derm on everything you need to know about masseter botox
With an ever-growing number of injectable treatments available, it’s easy to feel overwhelmed by choice. From Botox to fillers and everything in between, the world of aesthetics has expanded rapidly – but that doesn’t mean all treatments are right for everyone. It’s more important than ever to do your research, ask the right questions, and consult with a qualified professional before committing to any procedure. That’s why we’ve spoken to Dr. Anjali Mahto, consultant dermatologist at Self London, to break down one treatment that’s gained popularity recently: masseter Botox.
You’ve probably heard of Botox for wrinkles, but masseter Botox is a little different. It involves injecting Botulinum toxin into the masseter muscles on either side of the jaw. But how exactly does it work, and who is it best suited for? Dr. Mahto answers all your questions to help you make an informed decision before booking in…
What is masseter botox?
Masseter Botox is a treatment where Botulinum toxin is injected into the masseter muscles which are located on either side of the jaw. The aim of this is to reduce their activity. ‘It’s commonly used to treat conditions like teeth grinding (bruxism) or jaw clenching, which can cause discomfort, tension or even headaches in some people,’ explains Dr Anjali Mahto, consultant dermatologist at Self London. ‘By relaxing the masseter muscles, this treatment can also slim the appearance of the jawline, giving a softer facial contour.’
How does it work?
‘Masseter botox blocks the nerve signals that cause the masseter muscles to contract, leading to temporary muscle relaxation,’ Mahto explains. ‘Over a few weeks, the treated muscles gradually weaken, alleviating symptoms of tension and reducing the size of the muscle. The effects usually last around 3-6 months.’
Who is masseter botox suited for?
‘Masseter Botox is suited for individuals experiencing teeth grinding, jaw clenching or those seeking a slimmer jawline. It is particularly beneficial for patients suffering from temporomandibular joint (TMJ) disorders, as it helps relieve muscle tension and associated pain.’
However, masseter botox is not suitable for everyone. ‘Those with certain neuromuscular conditions, pregnant or breastfeeding individuals, or those with allergies to certain components within Botox should avoid this treatment,’ advises Mahto.
‘Additionally, people with active infections at the injection site or those on certain medications that affect muscle function may also be advised against it. This is why a thorough consultation with a qualified dermatologist is essential to determine suitability and ensure the treatment aligns with your individual health needs.’
What to know before a masseter botox treatment
First, a thorough consultation with a qualified dermatologist is crucial. They will assess your medical history, current medications and specific concerns to determine your suitability for the procedure.
‘You should be aware of potential side effects, which may include mild swelling, bruising, or temporary weakness in the jaw muscles. It’s really important at this point to discuss your expectations regarding results and duration too. Finally, consider any lifestyle factors, such as stress levels or grinding habits, as these may influence the treatment’s effectiveness.’
Are there any risks to having masseter botox?
Masseter Botox, while generally safe, does carry some risks and potential complications.
‘If too much Botox is injected, or if the placement isn't done correctly, it can lead to undesired effects,’ says Mahto. ‘Over-injection may cause excessive muscle weakness, resulting in difficulty chewing, facial asymmetry, or an overly "slimmed" appearance of the jawline.’
‘It’s about striking a balance. In rare cases, improper placement can lead to complications such as difficulty swallowing or breathing if the toxin spreads to adjacent muscles. Additionally, some individuals may experience bruising, swelling, or headaches post-treatment. To minimise these risks, it's vital to choose a qualified and experienced practitioner who understands facial anatomy and can tailor the treatment to your specific needs.’
