9.8　Challenges and Perspectives

With the development of modern science and technology，especially the major breakthrough of biotechnology，the application of biomedical polymer materials in the field of beauty will be more extensive，and the demand is also increasing.New biomedical polymer materials have the advantages of good biocompatibility，better biological activity and nontoxic side effects，etc.New materials are constantly appearing，bringing more new choices for cosmetic dermatology.The research on biomedical polymer materials by many research teams at home and abroad provides more reference data for its application in skin repair，functional cosmetics，skin fillers，auxiliary laser therapy and other aspects.The safety，histocompatibility and interaction mechanism of biomedical polymer materials in human skin and tissues need to be further studied.In addition，the commercial application of biomedical polymer materials still needs to be further explored.It is believed that with the development of more related studies，the application of biomedical polymer materials in cosmetic dermatology will have a wider prospect.We believe that biomedical polymer materials can be developed more rapidly，thus promoting the development of beauty industry.(https://www.daowen.com)
