Jawline Slimming in london

Reduce Teeth Grinding & Achieve a Slimmer Jawline

Jawline slimming can be achieved with the use of Botulinum toxin A injections into the masseter muscle. This muscle is responsible for chewing, and when overactive it can lead to teeth grinding (bruxism), jaw clenching, headaches, and a widened or square jawline.

At Surgicare Aesthetics, our jawline slimming treatments relax the masseter muscle to create a slimmer, more contoured jawline while also reducing the symptoms of teeth grinding. This is a particularly popular treatment with our Oriental patients, as it helps refine facial proportions while maintaining natural harmony.

All treatments are carried out in our CQC-registered Marylebone and Cockfosters clinics, led by experienced doctors to ensure safe, precise results.

How Does JAWLINE SLIMMING Work?

Consultation

Your treatment journey begins with a doctor-led facial assessment to evaluate jaw muscle activity, facial proportions, and aesthetic goals. We’ll discuss how targeted injectables can refine and contour your lower face, reducing the appearance of a square or heavy jawline — all while maintaining natural balance and symmetry.

Treatment

During your appointment, one of our doctors will precisely administer botulinum toxin injections into the masseter muscles on either side of the jaw. This helps to relax overactive muscles responsible for clenching or teeth grinding, gradually softening the jawline for a slimmer, more refined profile. The procedure takes around 20–30 minutes with minimal discomfort and no downtime.
