Dermal filler is hyaluronic acid, which is an acidic mucopolysaccharide. It is a component of the human body and has a strong moisturizing function. If the hyaluronic acid content in the human body decreases, it can lead to facial wrinkles, facial sagging, skin depression and other conditions.

Hyaluronic acid is often used in medical beauty. Small molecule hyaluronic acid can be used to repair the skin and directly applied to the skin to play a role in skin rejuvenation and moisturizing. Medium molecule hyaluronic acid can be used for facial filling, often used for small-scale filling such as cheeks, tear grooves, forehead wrinkles, crow’s feet, and nasolabial folds. Large molecule hyaluronic acid has a better supporting effect and is often used for filling the chin and nose. In addition, hyaluronic acid can also be used in various ophthalmic surgeries, as well as to treat arthritis and accelerate wound healing. Since hyaluronic acid is a preparation that can be absorbed by the human body, it generally does not produce side effects.
