First of all, many cosmetic surgery itself will not change life. Do you think a girl can change her life by making a single eyelid into a double eyelid? Most people who have plastic surgery are actually just meeting their psychological needs. Those artificial beauties boasted in advertisements can only believe 10% at most if they enter the film and television circle. People who can enter the film and television industry must first have good conditions and a little cosmetic help. Speaking of plastic surgery, it can really change a person's life. In medicine, the full name of plastic surgery is "plastic and reconstruction surgery". The initial purpose of plastic surgery is to improve the pathological appearance of patients, such as cleft lip and palate (without surgery, patients can't eat, drink and talk normally), serious trauma (without surgery, they can't enter social life normally), serious body diseases (with serious trauma) and severe burns (without surgery, patients may not survive). Finally, talk about failure. In fact, the risk of cosmetic surgery is not as great as the outside rumors. If you choose a regular hospital and doctor, it will not be more risky than ordinary surgery. This gives people a wrong impression, because many plastic surgeons are healthy people. Once their appearance does not meet their expectations, they may be dissatisfied. Second, most cosmetic patients, especially cosmetic patients, have high requirements on the appearance of the parts that need surgery, otherwise they will not spend money on surgery, so the effect of surgery sometimes has high expectations, which is beyond the control of doctors; Thirdly, many plastic surgery operations have been damaged by some private medical institutions and even beauty salons. The most famous case is breast enhancement by injection. I believe you have heard of it. Driven by interests, this method of breast augmentation, which violates the basic principles of plastic surgery, is popular in China, and even beauty salons without medical qualifications are carrying out this operation, resulting in tens of thousands of patients being injured. Regular plastic surgery, even if the operation fails, I mean that the appearance effect is not ideal, which can generally be adjusted by repair surgery. Other failures, such as massive bleeding, serious infection, serious scar, anesthesia reaction, etc. Similar to general surgery. Generally, there are corresponding medical treatments, so don't worry too much.
