Jowls are a common sign of ageing that appear as sagging or fullness along the jawline. They typically develop when the facial muscles and skin lose tone and elasticity, often becoming noticeable in the late thirties or early forties. This sagging can make the chin appear less defined and create a downward fullness along the sides of the face.

Several factors contribute to the development of jowls. As we age, the skin produces less collagen and elastin, proteins that give it structure and firmness. This reduction causes the skin to lose its natural support, making it more prone to sagging. In addition, the gradual loss of facial fat, particularly in the cheeks and mid-face, allows the skin to loosen and descend. Over time, gravity and the weakening of facial muscles and ligaments further accentuate this downward shift, resulting in the formation of jowls.

The process of jowl development is gradual, with the combined effects of reduced skin elasticity, volume loss, and tissue descent becoming more apparent over the years.
