The base of the nose can be filled with large molecule hyaluronic acid to achieve a better contouring effect. Large molecule hyaluronic acid has a harder texture and provides a better filler effect that lasts longer. Hyaluronic acid is a component contained in the human body. It will not harm the skin and muscles after injection, but will be completely metabolized by the body over time. Large molecule hyaluronic acid filling the base of the nose has the advantages of no surgery, little damage and no recovery period. However, the disadvantages are also obvious. The texture of the material is soft and the support is insufficient. It can only improve the slight depression of the base of the nose, and its effect is not long, so it needs to be injected repeatedly to maintain. Therefore, regular injections are needed to maintain long-lasting effects. In addition, the base of the nose can be improved by filling macromolecule hyaluronic acid, which is good at shaping and can make the nose look fuller and increase the aesthetics after filling. You can go to a regular hospital to do the surgery when filling, to avoid any bad phenomenon in the process, or affect the effect.
