Jowls are areas of sagging skin that form along the lower jawline and chin, often making the face appear older. They are typically caused by the loss of skin elasticity and the downward pull of gravity, leading to the accumulation of skin and fat. As the skin loses its firmness, the soft tissues beneath it can shift, resulting in the formation of jowls. Various treatments can help reduce or eliminate the appearance of jowls, restoring a more defined jawline.
