Hyaluronic acid is recommended to improve skin. Hyaluronic acid is only used for moisturizing and has been included in the ranks of wrinkle removal and plastic surgery. This plastic surgery is based on non-animal stable hyaluronic acid fermented by bacteria, and hyaluronic acid is injected as a filler into wrinkles, depressions or parts that want to be full, so as to achieve the effect of removing wrinkles and modifying the face, which can immediately remove wrinkles and change the appearance. The price of hyaluronic acid plastic surgery mainly depends on the amount of hyaluronic acid. Because hyaluronic acid plastic surgery is not only to increase the bridge of the nose, but also to consider the tip of the nose, and different people have different requirements for the height of the bridge of the nose, so the dosage of hyaluronic acid is different. However, in general, it is better to use 1-2 hyaluronic acid for hyaluronic acid plastic surgery.
