What are jaw and face slimming injections?

Do you feel that your jaw is too square or too wide? Do you grind your teeth? Jaw slimming and facial slimming injections could be the solution you need. 

Also known as masseter injections, jaw slimming or facial slimming using muscle-relaxing injections is a minimally invasive procedure to produce a more feminine shape to the lower face. The square-jawed look – which is highly desirable for men – is usually the result of overly-developed masseter muscles. These are the muscles attached to the angle of your jaw and they control your chewing.

Women who tense these muscles or grind their teeth can find that they can become more pronounced, creating a wider, more masculine-appearing jawline. Teeth grinding, known as bruxism, is typically involuntary and most patients aren’t even aware they are doing it. 

Asian women typically have a wider lower face than Caucasians due to the width of the jawbone, the thickness of the masseter muscle and underlying fat pads. Facial slimming with botulinum toxin has become an increasingly popular procedure for Asian patients.

Muscle-relaxing injections into the masseter muscle are a simple and effective non-surgical treatment for reducing your jawline, making your face look slimmer and more youthful. If you’d like to know more about jaw slimming treatment, call our London clinic and we can arrange a consultation for you.

How quickly will I see the results of my facial slimming procedure?

Muscle-relaxing injections work by blocking the nerves that activate our muscles. Over a period of approximately a week, the muscles will relax and the face will gradually become slimmer and smoother over the following weeks.

If you suffer from Bruxism or teeth grinding, this treatment should also ease any symptoms you might be experiencing such as facial pain, headaches, pain and stiffness in the jaw, disrupted sleep or tooth sensitivity.
