Masseter Muscle Relaxation

Masseter muscle relaxation is a non-surgical treatment designed to slim the jawline and relieve jaw tension, teeth grinding, and related discomfort.

The masseter muscles, located on each side of the jaw, are responsible for chewing and clenching, and when overactive, can cause jaw pain, headaches, and a wider facial appearance.

By carefully relaxing these muscles, the treatment helps reduce discomfort while creating a softer, more balanced jawline, all while maintaining natural movement.

Common Concerns

Clients often seek masseter muscle relaxation treatment for either medical relief or facial slimming, or a combination of both.

Treatments process

Masseter muscle relaxation treatment is quick and minimally invasive.

1. Personal Consultation

Your appointment begins with a detailed personal consultation, where we discuss your concerns and symptoms, assess your jaw muscles and facial structure, and determine whether you are experiencing bruxism or jaw tension.

Based on this, we recommend a personalised treatment plan tailored to your facial anatomy and goals, whether that is jawline slimming, relief from grinding, or both.

2. The Procedure

The procedure involves a few small injections into the masseter muscles on each side of the jaw. The treatment takes approximately 30 minutes, involves minimal discomfort, requires no anaesthetic, and has little to no downtime, allowing most clients to return to their normal activities immediately.

3. Aftercare

After treatment, you will be given simple aftercare advice to ensure optimal results. This typically includes avoiding touching or massaging the area for 24 hours, refraining from strenuous exercise for the rest of the day, and remaining upright for several hours after treatment.

The Results

Masseter muscle relaxation treatment offers both functional relief and aesthetic enhancement, helping to reduce jaw tension, clenching, and teeth grinding, while also minimising tension headaches and creating a softer, slimmer jawline with improved facial balance.

Relief from grinding can begin within 1–2 weeks, with visible facial slimming developing gradually over 4–6 weeks, and results typically lasting 3–6 months depending on individual factors. 

Before & After Expectations

Clients often report less jaw tension on waking, reduced grinding, a softer facial appearance, and greater comfort in daily activities.
