The jawline is a complex anatomical area that can be further defined in both younger and older patients. For some, it is subtracting volume and reducing fat in the area through treatments like Kybella. For others, it can be a matter of adding a little volume in the form of fillers or collagen under the skin to increase angularity and tightness. In the long term, addressing collagen production supports the foundational matrix of tissues that provide structure, lift, and projection to the area. Collagen loss can impact the jawline as it plays a vital role in maintaining the skin’s firmness, elasticity, and structure. The jaw muscle, called the masseter, plays a crucial role in profile balancing. When the masseter muscle atrophies or weakens, its size and prominence can decrease.
