One of the first changes we see in our face when we start aging are the smile lines or the naso - labial folds. These lines run from the nose to the corners of the mouth. Loss of collagen and bone support, combined with sagging of the cheek tissues, are responsible for the formation of the naso - labial folds. As the fat compartments of the mid-face descent and deflate, the appearance of the fold becomes even deeper.
On the other hand, the marionette lines cruise from the corners of the mouth downward to the jaw line and often times give a sad or bitter look to the face.The prime example for this type of appearance is the German chancellor - Angela Merkel.
Although most people are distressed by the smile lines or naso - labial folds, they are less aging than the marionette lines. A smile line might be present in a young and skinny person, but a marionette line is found only in older persons. This is a reason why marionette lines are more aging than smile lines.
If you ever have to choose between marionette and smile line correction because of budgetary or time constraints, always opt for marionette correction first. Depending on the magnitude of volume loss, one or two syringes of filler might be needed to achieve optimal results in this area. The effect should last for 6 months. After repeated injections, as the collagen is replenished, the treatment may be gradually spread out to every 8-9 months.
