Plastic surgery experts at Shanghai Midland Johnson & Johnson Hospital said that filling the nasolabial groove with hyaluronic acid is to inject hyaluronic acid into the nasolabial groove and fill it, thus playing a role in wrinkle removal. The principle of filling nasolabial groove with hyaluronic acid is that hyaluronic acid is a natural moisturizing factor existing in human skin tissue. When I was young, my skin was rich in hyaluronic acid, so my skin was soft and elastic. With the increase of age, hyaluronic acid gradually decreases, leading to skin aging, loss of elasticity and luster, and then wrinkles. The role of hyaluronic acid in filling nasolabial groove: hyaluronic acid plays a role in stabilizing the integrity of extracellular matrix in cell matrix, which is non-toxic and has no inflammatory reaction. It is mainly used for soft tissue enlargement and filling. Hyaluronic acid can fill the deep nasolabial groove (legal line), forehead line (forehead line), crow's feet, brow line or superficial fine lines around the mouth without leaving traces, which also shows that hyaluronic acid has a good effect on filling nasolabial groove. So now it is often used to fill nasolabial groove.
