To put it simply, you need to take a small piece of your own cartilage and insert it into your nose to achieve the effect of rhinoplasty~

You can remove ear cartilage from the ear or from the chest. Make an incision below and remove the costal cartilage.

The advantage is that it is natural, looks very real, and its own parts will not cause rejection or infection. The disadvantage is that it will deform and absorb, but I feel that compared to silicone, expanded or self-derived cartilage is better.
