Jawline Slimming

The procedure

Wide, or square, jaws can be caused by overactive masseter muscles in the sides of the face, used when chewing. Bruxism, or grinding teeth (consciously or subconsciously during sleep) can cause your masseter muscle to grow in size, leading to a heavier-set jaw. ​ Jawline slimming for cosmetic purposes is a simple and effective procedure that involves injecting the large masseter muscles to create a slim and more feminine jawline.

The most common asked questions

+ - How many sessions will I need, and how far apart can I have them?

One session is enough to notice a difference, but this is seen as an ongoing treatment, so it should be topped up every 3-4 months for continued slimming results.

+ - Am I a suitable candidate?

A wide jaw caused by an overactive masseter muscle is treatable, whereas a wide jawbone is not, and may require a more invasive procedure. To find out more about jawline slimming and whether you are suitable candidate for treatment, you will need to have a consultation.

+ - Any side-effects?

Side effects for this treatment can include swelling and redness, due to the injectable nature of the treatment, but any concerns you have should be raised with your assigned clinician in your initial patient consultation. Most patients report reduction in swelling and redness within 24 hours, with results visible from 5-7 days post treatment, and optimal results at 2-3 weeks.
