Drooping mouth corners: causes and treatment

We’ve all been accused of our resting (B****) faces not necessarily telling a true tale of how we feel, as drooping mouth corners can make us look sad, tired or just plain angry.


Introduction to Drooping Mouth Corners

Have you ever wondered what causes the sagging skin on the corners of your mouth? This common concern can be attributed to a specific set of muscles in the jaw known as the depressor anguli oris (DAO). Extending from the corners of the lips down to the chin, these muscles can contribute to a tired and aged appearance. 


Additionally, as we age, there is a natural loss of volume in the cheeks and lateral sides of the face, which further accentuates the effects of drooping corners. Understanding these underlying factors helps us address this issue effectively, restoring a more youthful appearance.

Other causes of droopy lines around mouth

  • Ageing. The natural ageing process, which results in the natural loss of collagen and elastin, proteins that control how plump and firm skin is. As these deteriorate, skin can sag or look lax, which, especially around the mouth, can lead this concern.


  • Smoking accelerates the natural ageing process, restricting blood flow to the top layer of skin, depleting vitamins and nutrients, and actively destroying collagen to affect the skin’s ability to “bounce back” from facial expressions as it is looser or saggier.


  • Genetics can also play a part in how the mouth looks, generally being passed from mother to daughter and father to son.

The most effective approach to addressing drooping mouth corners is to intervene early. By focusing on tightening the facial muscles, we can lift the corners of the mouth and enhance the jawline. This can be achieved through Botox injections, which relax the muscles around the mouth, preventing repetitive movements that pull the lip corners downward. 


Additionally, dermal fillers play a crucial role in providing structural support to the cheek and jawline, resulting in a lifted appearance. Together, these treatments offer comprehensive solutions to combat sagging mouth corners and achieve a more youthful aesthetic.
