In Latin language, naso means nose, labial lip. Nasolabial means the line between the nose and lips, the laugh line we know. This is a line formed in the junction of the muscles here with the skin at the attachment points. The nasolabial line begins to deepen as we age. When we are not laughing, there is a line appearance. Some people may have a line at an earlier age due to the structure of the face and face shape.
The deepening of this line and its further progression, especially from the corner of the mouth, give the person a tired, age-old appearance.
Nasolabial folds are the form of wrinkles on the inner cheek. It occurs in the area from the bottom of the nose to the corners of the mouth. These wrinkles are found in everyone to some extent and become deeper depending on age, decreased collagen production, and other factors. Of course, the main reason for this situation is the sagging of the facial SMAS tissue, the part that contains the muscles and nerves on the face.
Chronic sun exposure also severely damages the elastin and collagen in the skin, which causes the nasolabial folds to become more prominent. Losing excess weight in a short time will cause a decrease in facial fat pads and subcutaneous adipose tissue, which leads to a deepening of the nasolabial lines.
Smoking and alcohol use and sleep patterns also deepen the nasolabial folds. It usually begins to bother after the age of 35-40.
