It is a sign that distinguishes the cheek from the mandible, and the nasolabial groove is formed by the interaction of dynamic tissue and non-dynamic tissue on the cheek. People make many expressions through nasolabial sulcus. We will use nasolabial groove a lot in our life, so we will deepen, widen and extend nasolabial groove. In addition, when we are over 30 years old, the face will gradually age and deepen the nasolabial groove. Nasolabial sulcus is an important sign to measure a person's age.
Causes of nasal groove formation:
1, the skin itself is tired, thin, lacking elastic fibers, and stretched by gravity; Zygomatic arch ligament and cutaneous masseter ligament lack elasticity and relaxation due to failure, and are elongated due to gravity; The difference between the outer upper part and the inner lower part of nasolabial groove is that the outer upper part is loose and the inner lower part is dense;
2. Nasolabial groove is the fulcrum of power arm and resistance arm after long-term repeated movement of facial muscles. Long-term repeated movement of facial expression muscles causes shear stress between skin and facial fat pad, and the skin and facial fat pad produce downward relative displacement, which accumulates on the lateral upper part of nasolabial groove to form nasolabial groove ridge.
Long-term repeated movement of the expression muscles causes relative movement between the upper and lower tissues with different textures and structural densities in the nasolabial groove, thus forming wrinkles between the two tissues, thus forming the nasolabial groove.
