Removing nasolabial groove is to tighten facial skin, lift facial soft tissue or fill wrinkles in nasolabial groove by medical technology, so as to remove or alleviate nasolabial groove and improve facial aging. Commonly used technical means include surgery, injection filling and physical wrinkle removal.

Causes of nasolabial groove

The formation of nasolabial groove is the main sign of facial central aging. It can be recovered in the early stage, and it will become a permanent wrinkle with age. Nasolabial sulcus is a kind of mixed wrinkle with complicated formation mechanism.

First of all, the dynamic function of related muscles is an important reason for the formation of nasolabial groove. Facial expressions such as smiling and crying need zygomatic muscles and zygomatic muscles.

Removal of nasolabial groove

Muscle contraction, levator labia muscle and other muscles participate. When these muscles contract, the cheekbone tissue forms a depression along the folds, which is the nasolabial groove in the dynamic state (see Figure 3). With the increase of age, the formation of nasolabial groove gradually changed from dynamic to static. Like other wrinkles, perpendicular to the direction of muscle traction.

Secondly, the atrophy of soft tissue, including skeletal muscle and soft tissue, makes relatively redundant skin locally, and the subsidence of these skin deepens the nasolabial groove.

Thirdly, with the increase of age, natural aging makes the subsurface skin from nasolabial groove to mandibular margin relax gradually, and the role of gravity becomes more and more obvious; Photoaging leads to the weakening of the elasticity of dermal collagen fibers in skin tissue, and also aggravates the aging of nose and lips.

In a word, the main factors of nasolabial groove formation include repeated muscle contraction, soft tissue atrophy, skin relaxation and unsupported, and photoaging leading to decreased skin elasticity.
