If you have an injection rhinoplasty, it's not permanent. The main method of augmentation rhinoplasty by injection is injection, and the injected materials are fused with the surrounding soft tissues, so its fatal disadvantage is that once the effect is not ideal or there is rejection, it is not easy to take it out completely, and the effect is not lasting and it will be absorbed by the human body.

Generally, a single injection of collagen can maintain the effect of rhinoplasty for one year to one and a half years. If the second injection, such as supplementary treatment after one year, may prolong the maintenance time, generally reaching two years or even longer. The materials used for collagen will be different, some are macromolecules and some are small molecules, and the maintenance time of rhinoplasty effect will be slightly different.
