If the lips are too thin, it will give people a bitter feeling. The best way to change this situation is to inject lip augmentation. Of course, hyaluronic acid, autologous fat and other lip augmentation materials are very good lip augmentation materials. But what kind of material to choose to enrich lips needs to be decided according to your own actual situation. I suggest you go to Zhimei to consult a plastic surgery hospital doctor and get more professional and reasonable advice.
