1. Prohibited substance for injection 1: polyacrylamide hydrogel.

Polyacrylamide hydrogel is a new type of microplastic material used for soft tissue filling. This kind of material is always soft after being put into the human body, which makes the tissue at the injection site unable to stand tall and straight and difficult to shape.

2. Injection of prohibited substance II: hydroxyapatite

Hydroxyapatite is also called artificial bone. I don't know when or why, someone used it for rhinoplasty. At first, users may not know that this material is actually an old material for repairing bone defects with a long history. This material exists in the form of particles and powder, and its hardness is extremely high, so it cannot be molded. Even a doctor with superb medical skills can't give full play to his skills.

3. Injection of banned substance III: liquid silica gel

Liquid silicone injection for rhinoplasty was ten years ago. Because there are too many complications, disfigurement cases occur frequently, and the treatment is very difficult. About 90 years ago, under the strong appeal of relevant experts, this microplastics material has stopped being used.
