Hyaluronic acid is recommended to improve eye skin. Hyaluronic acid stock solution is the best moisturizing and water-locking component, and the effect is extremely remarkable. However, with the increase of age, hyaluronic acid in the skin is also decreasing. Applying this stock solution can help the skin to enhance elasticity, maintain moisture and restore youth. 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.
