Sculpt a Refined Jawline Without Surgery in Marylebone

What is Jaw Reduction?
Slim and contour your jawline with our masseter reduction treatment. Ideal for those seeking a more refined facial shape or relief from teeth grinding.
Jaw reduction treatment, also known as masseter reduction, is a non-surgical procedure that slims and contours the lower face by relaxing the masseter muscles. At Mesglo London, our expert practitioners use botulinum toxin to reduce the size of these powerful chewing muscles, creating a more refined, V-shaped facial silhouette. This treatment is particularly popular among those with a square or wide jawline who desire a softer, more feminine appearance, as well as those suffering from bruxism (teeth grinding) or TMJ discomfort. The procedure is quick, comfortable, and requires no downtime. Results develop gradually over 4-6 weeks as the muscles relax and reduce in size, with effects lasting 4-6 months.

Questions people ask
How does jaw reduction treatment work?
The treatment uses botulinum toxin to relax the masseter muscles. Over time, these muscles reduce in size, creating a slimmer, more contoured jawline. The effect is gradual and natural-looking.
Will jaw reduction affect my ability to chew?
No, the treatment targets only a portion of the masseter muscle. You will still be able to chew normally. Most clients notice no difference in their chewing ability.
How long until I see results?
Results develop gradually over 4-6 weeks as the muscles relax and reduce in size. Full results are typically visible at around 6-8 weeks.
Is jaw reduction treatment permanent?
Results typically last 4-6 months. With regular treatments, results may last longer as the muscles become trained to remain relaxed.
Can jaw reduction help with teeth grinding?
Yes, many clients experience significant relief from bruxism (teeth grinding) and associated jaw tension and headaches after treatment.
