Jowls are the sagging skin that forms along the lower face and jawline, often as a result of aging and collagen depletion. Over time, gravity, lifestyle choices, and environmental factors such as sun exposure contribute to skin laxity. Some people may develop jowls earlier due to genetic predisposition, while others notice them after weight fluctuations. This change in facial structure can make a person look older or more tired than they actually are. However, various cosmetic solutions exist to tighten and redefine the jawline, restoring a youthful appearance.
