Jowls are the sagging skin that forms along the jawline on either side of the chin. This common concern often becomes more noticeable with age and can be attributed to three primary factors: the loss of facial volume, the gradual loosening of the skin, and the laxity of facial ligaments. These elements contribute to skin from the mid-face, particularly the cheeks, descending and forming nasolabial folds, marionette lines, and jowls.
