1. hyaluronic acid: scientific name "hyaluronic acid". It is the most common substance in medical beauty. Hyaluronic acid can be divided into macromolecules and micromolecules. Small molecules are generally used for hydrating beauty, while large molecules are generally used for filling, such as rhinoplasty and chin pad.

2. Silicone rhinoplasty: Silicone is a common material for rhinoplasty in plastic surgery institutions. Similar to human cartilage, it is easy to cut and has strong plasticity, good biocompatibility, no toxicity and teratogenicity, and the rhinoplasty effect is very ideal. However, it will cause light to spread in the nose, and some allergic people will have certain allergic reactions. But now silicone rhinoplasty has rarely used L-shape as a prosthesis for overall rhinoplasty. Because of a little carelessness, it is easy to deform the nose due to capsular contracture in the later stage, forming a pig nose with everted nostrils.

3. Augmentation rhinoplasty: it is a porous solid material produced in the United States. It has many micropores and its properties are extremely stable. Soft and easy to plastic, the tip of the nose is opaque and not red. The operation is more realistic, but if there is infection after operation, the prosthesis needs to be taken out, which is more expensive than silicone.

4. Autologous cartilage: There are three kinds of cartilage that can be used as rhinoplasty materials: ear cartilage, nasal septum cartilage and autogenous costal cartilage. Autologous cartilage tissue has good compatibility and stability, and there will be no rejection. It is easy to survive after transplantation and has no stimulation to tissues after implantation. This rhinoplasty material is suitable for the overall plasticity of rhinoplasty and the special plasticity of nasal tip. It has good compatibility with nasal tip cartilage, real effect, no complications and no displacement infection, but it will have a certain absorption rate.
