What materials are used to fill the nasolabial folds? Who are not suitable for nasolabial folds?

As we age, the nasolabial folds will become deeper and deeper. The deeper the nasolabial folds are, the older and uglier we will look. So what material is best for filling the nasolabial folds? Let’s learn about it below.

The nasolabial groove is located at the junction of the cheeks and upper lips on both sides, and runs diagonally outward and downward from the outer edge of the nose. In young people, the nasolabial groove is only obvious when they make facial expressions such as smiling, pouting, and puffing cheeks. As we age, the facial muscles become looser and looser, and the nasolabial groove becomes more and more obvious. Therefore, obvious nasolabial grooves are one of the important manifestations of aging. Once the nasolabial grooves become flatter and shallower, people will immediately look younger and more beautiful.

The nasolabial fold is formed by the interaction between the dynamic and non-dynamic tissues of the cheek. Many of people's facial expressions, such as smiling and crying, are initiated by changes in the morphology of the nasolabial fold. For example, smiling begins with the muscles around the nasolabial fold. When they contract, the upper lip is pulled backward toward the nasolabial fold. Due to the thick subcutaneous fat in the cheek, the lips encounter resistance at the nasolabial fold, causing the nasolabial fold to bend and deepen. Similarly, in expressions and actions such as crying, showing teeth, and chewing, the nasolabial fold will bend and deepen.
