Before plastic surgery, no matter the size of plastic surgery, a beauty contract must be signed. Signing a beauty contract is the protection of the rights and interests of both medical parties, and the protection of patients will be more prominent. We can't guarantee the doctor's operation method during the operation, but we can see the effect after the operation. If the doctor's operation is not satisfactory, the beauty contract signed at this time will play its legal role and protect the legitimate rights and interests of patients from infringement. If the hospital won't let you sign a beauty contract, you should take the initiative to ask. It is irresponsible for the hospital not to let you sign a beauty contract, so you should choose carefully.
