I believe that they themselves know the harm of plastic surgery, so they don't do it. In order to make profits for plastic surgery hospitals, they will definitely use superb technology to tell plastic surgeons that there is no harm or even sequelae. Just think about it.

Who will admit that their hospital is not good? As for those stars who go for plastic surgery, first, for the sake of career development, the return is greater than the injury and pay, so it is cost-effective, and second, they have money to deal with sequelae later. Plastic surgery doesn't mean once and for all. Second, it means regular maintenance.
