1, the function of hyaluronic acid gel: hyaluronic acid gel has the function of hydrating and moisturizing. Hyaluronic acid is a component contained in dermis and other tissues and organs, such as eyes and articular cartilage. It can combine with a large number of water molecules, so it is a very good humectant.

2, for external use, because it can't penetrate the skin and be absorbed by the skin, it is only the moisturizing effect of the skin surface.

3. In addition to external use, it can also be injected into the superficial dermis through a water needle, or injected into the dermis with a syringe needle, which can play the role of moisturizing and local filling. Hyaluronic acid is widely used in dermatology and plastic surgery, but it will be metabolized over time after injection and needs to be supplemented.
