Changes to the jawline are a common concern for many people, and understanding what drives these changes can help inform decisions about treatment options. This page explains the factors that influence jawline appearance and provides information about volume-adding treatment as one non-surgical option that may be considered.
A consultation at Ascension Cosmetic Medicine with Dr Scott Allison is recommended as a starting point. This allows your clinician to assess your individual anatomy and discuss whether treatment may be appropriate for your circumstances.
Why does jawline appearance change over time?

Changes in jawline definition and contour are a natural part of ageing. Contributing factors include the gradual reduction in bone density and structural support, which can cause facial fat and soft tissue to shift position over time.
Collagen, a protein that contributes to skin firmness, also naturally decreases with age. As collagen production reduces, the skin’s supporting structure may weaken, which can contribute to changes in the contour of the lower face. These are normal biological changes that occur as part of the ageing process.
What is the procedure?
Jawline treatment is a non-surgical procedure that aims to address contour and structure in the lower face. As with all cosmetic procedures, there are potential risks and side effects — including but not limited to swelling, bruising, tenderness, and less common vascular complications — that will be discussed with you in full during your consultation prior to treatment.
How is the approach to treatment determined?
Treatment can be tailored to different anatomy and individual goals. During your consultation, your clinician will assess your facial anatomy and proportions and discuss what approach may be appropriate for your circumstances. Some patients seek more angular definition; others seek a softer change in contour. The treatment plan will be based on your individual assessment.
How long do they last?
Individual results vary. The duration of results is influenced by factors including metabolism, lifestyle, and overall health. Your clinician will discuss what to expect in terms of longevity based on your individual circumstances during consultation.
What should I expect after treatment?
Mild swelling and bruising in the treated area are common following this procedure and generally subside within a few days, though individual recovery varies. It is advisable to avoid exercise for the first 24 hours following treatment and to keep the area clean and free from makeup during the initial recovery period. A cold compress may help ease temporary discomfort. Your clinician will provide personalised aftercare instructions at your appointment.
Most importantly, every treatment is designed with you in mind. At Dr Scott Allison’s clinic, we take a personalised approach to cosmetic care, because every face is unique and every client deserves results that feel like their own.
Is this treatment appropriate for you?
Jawline enhancement may be worth considering for those who have noticed changes in the contour or definition of their lower face and wish to explore non-surgical options. Whether this treatment is appropriate depends on individual anatomy, health status, and other factors that can only be assessed during a clinical consultation.
