When we worry about lines and wrinkles forming as we age, we tend to focus on the upper part of the face. But did you know that your lips and mouth area can show visible signs of aging as well? With age, fat and collagen that were once evenly distributed can deteriorate, resulting in thinner skin and noticeable lines and wrinkles. Lip shape, fullness and definition are based on a variety of factors including genetics. Over time, lips become thinner and can lose definition. The cupid's bow of the upper lip begins to flatten, vertical lines appear and become deeper with age. Even bone loss can occur, resulting in decreased lip volume and lengthening around the mouth. For more information, talk to your doctor to find out how you may be able to address these signs of aging.
