The lines that run from the nose to the mouth are known as nasolabial folds. These lines tend to develop as the area’s skeletal and fat structures alter. Nasolabial creases can also form as a result of frequent facial expressions, decreased collagen formation, and fat breakdown.

​

Marionette lines are creases that appear on the face as a result of normal aging. These are straight lines that form between the lips and the chin, which cause sagging in the lower part of the face. Because the skin around your lips is thinner than the remainder of your face, it is more prone to wrinkles.

Muscle fatigue, gravity, and the depressor muscles at the edges of your mouth are the three main elements that contribute to marionette folds and lines.  Gravity has an impact on your face every day.  Part of the aging process causes your cheekbones and face to begin to slide downward and inward over time, resulting in nasolabial folds and marionette lines.

​

Volume loss is the second most common cause of marionette lines and folds. It can be the soft tissue volume decrease, in which fat skin gets lighter, or the loss of bone volume.

The persistent activation of the depressor muscles in your mouth corners is the final factor that contributes to the development of these lines and folds. When this muscle is repeatedly stimulated, it gives the appearance of a sad face. Many people unwittingly utilize this muscle, which causes their mouth edges to drop down.
