    Suitability

    Suitable candidates for face & jawline slimming treatments typically:

    • Are concerned about a square or wide jawline, which may be associated with teeth grinding & jaw clenching.

    Book a consultation to personalise your treatment to your goals, and take the first step toward a slimmer face & jawline.

    Preparation

    Getting ready for your facial slimming treatment is simple:

    • Arrive with a clean face – just remove your makeup.
    • Hydrate before you arrive.

    We’ll provide more detailed easy-to-follow preparation instructions when you book.

    Aftercare

    After your facial slimming treatment, avoid touching your jaw for 4 hours and applying firm pressure to your cheeks or chin for up to 5 days, depending on which areas were treated.

    If you notice any redness, gently calm your skin with a wrapped cold pack for 20 minutes per hour.

    We’ll provide simple, easy-to-follow aftercare instructions during your appointment, so you can get straight back to your day.

    Results

    You’ll see a softer, slimmer lower face and jaw develop shortly after your treatment.

    Over time, results gently fade as the treatment is metabolised by the body. How long they last depends on your treatment plan, skin type, lifestyle, and metabolism.

    If you’d like to maintain your slimmer look, repeat treatments can be discussed during your consultation.

    Masseter muscles

    The masseter muscles, which are responsible for chewing, directly affect the width of your jaw. Enlarged masseters may be genetic or develop over time from habits like chewing tough foods or gum.

    Cheekbones

    The contour and projection of the cheekbones influence overall face shape, and can affect how wide your face looks. Strategic cheek contouring can support facial slimming by rebalancing the mid and lower face, helping to create a softer, V-shaped profile.

    Chin

    The length and projection of the chin influence the proportions of the lower face and can affect how wide the jaw looks. Adjusting chin length or projection can rebalance facial proportions, giving the face a slimmer and more tapered appearance.

      Facial slimming treatments may be suitable for people with mild to moderate concerns about a wide-looking lower face who want natural-looking refinements, such as a softer jawline or increased cheek and chin balance. The best way to determine suitability is through a personalised consultation, where your clinician will assess your facial structure, muscle activity, and skin quality to design a treatment plan tailored to your goals.

      Facial slimming is a non-surgical treatment that aims to reduce the appearance of a wide lower face, often caused by overdeveloped jaw muscles, a small chin, or flat cheekbones. This treatment aims to create a slimmer facial profile. The treatment targets specific muscles and cheek and chin structure, which may lead to a slimmer face shape.

      Facial slimming treatments are generally well tolerated, although each person’s experience of discomfort will vary. Numbing creams or cooling techniques can be used to minimise any discomfort.

      When considering facial slimming, it’s important to understand that the time to results varies depending on the approach used. Results typically emerge over days to weeks.

      Results from facial slimming treatments typically last months to years, but the exact duration varies depending on the treatment method. Multiple treatments may be required initially, and if you wish to maintain your results, follow-up treatments can be scheduled at an interval determined during your consultation.

      Some facial slimming treatment methods that target the masseter muscles may provide relief for symptoms associated with Temporomandibular Joint (TMJ) disorders.

      Some facial slimming methods may help individuals who experience teeth grinding (bruxism) and jaw clenching. These habits are frequently linked to overactivity or tension in the masseter muscles, which are the primary muscles involved in chewing and jaw clenching.

      After facial slimming, you may experience mild swelling or tenderness which settles over the following days.

      Depending on your personalised plan, results will emerge within days to weeks.

      During your consultation, your clinician will outline what you can expect after treatment, based on your personalised assessment and treatment plan.

      Facial slimming is generally considered low-risk when performed by experienced, qualified clinicians. Most patients experience minimal side effects, such as mild swelling or temporary redness, which usually resolve within a few days.

      During your consultation, your clinician will review your medical history, assess your facial structure, and discuss any potential risks to ensure that the treatments are appropriate for your individual needs.

      The side effects of facial slimming are typically mild and temporary. Some people may experience slight swelling, redness, or tenderness in the treated areas, which usually resolves within a few days. Less commonly, minor bruising or sensitivity, or rarely, infection can occur.

      Your clinician will provide information on treatment risks and how to minimise them during your consultation.
