The lines can be caused by smiling too much, or by aging and abnormalities in the bony structure of the face.
The nasolabial folds are gradually deepened when smiling due to the pulling of the expression muscles. If you usually smile too much or have too rich facial expression, it may lead to the appearance of worry lines. Therefore, smiling too much may lead to the appearance of lines.
In addition, as we age, the skin tissue loosens and sags, which can deepen the nasolabial folds and lead to the appearance of the glabellar folds. In some patients, the nasolabial folds are deeper than those of their peers due to poor development of the bony structures of the face, which can lead to the appearance of worry lines.
If patients feel that their nasolabial folds are too obvious or if they are in need of aesthetic enhancement, it is recommended that they go to the dermatology department of a hospital in time to see a doctor and choose the appropriate treatment plan.
