Non-Surgical Jaw Slimming

Precision muscle relaxation to contour the lower face and refine your jawline.

Achieve a beautifully contoured, softer facial silhouette without the need for surgery.

Non-surgical jaw slimming—also known as masseter reduction—is a highly precise aesthetic treatment designed to reshape a prominent or square jawline. By utilising targeted muscle-relaxing injections, this treatment gently softens the lower face to create a more balanced, refined profile.

We are predominantly a clinic specialising in the treatment of Migraines and TMJ conditions, of which the Masseter muscles form only a part of that treatment We have includes a separate treatment purely for “jaw slimming” it is important to recognise that this is not a therapeutic treatment for a medical condition, purely cosmetic. Nonetheless, it should only be carried out by clinicians such as Dental, Oral or plastic surgeons with a precise training in the anatomy and physiology of ALL the facial muscles of mastication (jaw movement)

How Masseter Reduction Works

The masseter muscles are the powerful chewing muscles located on either side of your lower jaw. Due to genetics, habitual jaw clenching, or teeth grinding (bruxism), these muscles can become overdeveloped and bulky. This overdevelopment often results in a wider, square, or more masculine lower face.

By injecting medical-grade neuromodulators, botulinum toxin, directly into the masseters, we safely relax the muscle activity. Over the following weeks, the muscle naturally shrinks in volume. This structural change slims the lower face into a softer, more balanced, oval or heart-shaped profile.

The Truth About Filler Longevity: Longevity, Migration, and Fixes

Hyaluronic acid (HA) fillers primarily migrate and persist rather than simply dissolving on a predictable 6 to 12-month timeline. While the body’s natural enzymes do break down HA, cross-linking in fillers makes them highly resistant. Consequently, un-dissolved gel deposits can remain trapped and shift under the skin for years.

The Science of “Dissolving” vs. Reality

  • Long-Term Persistence: MRI studies have revealed HA filler residue lingering in the skin 5, 10, or even 15 years after the initial injection. The gel does not magically disappear; it integrates into your soft tissue and continues to draw in water.
  • Natural Breakdown Limitations: Your body naturally produces an enzyme (hyaluronidase) that breaks down HA. However, this natural breakdown is most active in the first few weeks following an injection. The body does not maintain sustained, high levels of this enzyme long-term, as it would destroy your body’s native HA.

 

Understanding Filler Migration

  • How It Happens: Filler does not just sit completely still. Over time, factors like gravity, repetitive facial muscle movements (smiling, chewing, talking), and lymphatic spread cause the gel to disperse and settle into surrounding areas.
  • Overfilling: Migration is highly accelerated by repeatedly “topping up” the same area with too much product over time, eventually causing the tissue to lose its shape and the filler to spill out of the original injection plane.

 

How to Fix It

If you notice lumps, puffiness, or volume where it shouldn’t be (such as above the lip border or under the eyes), the filler needs to be actively corrected:

  • Synthetic Hyaluronidase: A trained practitioner can inject synthetic hyaluronidase, an enzyme that safely breaks down and dissolves the HA gel, allowing your body to naturally reabsorb it.
  • Multiple Sessions: Because migrated filler is often spread out into the tissue, achieving a complete correction may require multiple sessions of hyaluronidase.
