Lippenrand

Lippenrand, also known as the labial commissure or corner of the mouth, is the anatomical junction where the upper and lower lips meet. This area plays a significant role in facial expression, speech, and oral function. The lip corners are formed by the convergence of the orbicularis oris muscle, which encircles the mouth, and surrounding connective tissues.

The lip corners are influenced by various factors, including muscle tone, skin elasticity, and underlying bone structure. With age, natural changes such as muscle weakening, collagen loss, and skin thinning can lead to sagging or asymmetry in the lip corners, contributing to a less defined or uneven appearance. This condition is often referred to as "marionette lines" when vertical lines extend downward from the corners of the mouth.

Lip corners can be affected by both functional and aesthetic concerns. For example, conditions like Bell’s palsy, which causes temporary facial nerve paralysis, may result in drooping at the lip corners. Aesthetically, individuals may seek treatments to enhance symmetry, fullness, or youthfulness in this area. Common interventions include injectable fillers, such as hyaluronic acid, which temporarily restore volume, or surgical procedures like facelifts or lip lifts to reposition sagging tissue.

Maintaining overall skin health through hydration, sun protection, and a balanced diet can help preserve the natural appearance of the lip corners. Professional consultations with dermatologists or plastic surgeons can provide personalized recommendations for addressing specific concerns.
