Hyaluronic acid has a wide range of applications, which can be used as plastic materials for eyes and nose and also as skin care products. The skin care products of hyaluronic acid stock solution are generally high-concentration hyaluronic acid, because its principle is to absorb the surrounding water to the water-deficient parts, so it must be used with lotion. After washing your face in the morning and evening, drop two drops of hyaluronic acid on your palm, and add a proper amount of emulsion to smear it on your face (or fully mix the whole bottle of emulsion at one time and use it several times), because hyaluronic acid is only a water-absorbing moisturizing agent, and if you don't supplement the water-locking moisturizing agent, the moisturizing effect will not be too good, but it may bring side effects. Therefore, skin care products containing oil must be rubbed, and the moisturizing effect can be complete. At present, hyaluronic acid is also a popular material for subcutaneous injection in the plastic surgery field, because hyaluronic acid originally exists in the skin and has a strong moisturizing effect, and there is almost no allergic reaction after injection into the human body. Hyaluronic acid for injection is a purified component. After injection, it will fuse with the original hyaluronic acid in the body, the skin will swell, and the wrinkles will flatten and swell, which is extremely safe.

Hyaluronic acid will be gradually absorbed by human metabolism after injection, and the effect can last for about 8 months each time. At present, it is widely used to fill the wrinkles between decrees, sunken corners of the mouth, forehead and eyebrows, and can even be used to repair the nose and nose, enrich the lips, repair the chin, and correct acne and chickenpox scars.
