Hyaluronic acid stock solution is the best ingredient to moisturize and lock water, 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, keep it moist and rejuvenate. 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.
