People have different definitions of "beauty". Some people who love beauty will choose to change their appearance through plastic surgery. What if they find ugly after plastic surgery and the beauty salon refuses to admit the failure of plastic surgery? At this time, we can negotiate. If negotiation fails, relevant evidence can be collected to solve the problem. At present, there is no mandatory standard for cosmetic plastic surgery industry in China. In other words, the success or failure of surgery is generally decided by plastic surgery hospitals. If the victim is stubborn, it may not have a good result. Suggestions can be solved through litigation, but through litigation, the injured party may be at a disadvantage in fixing evidence. At this time, you should consult a professional damage compensation lawyer or a lawyer who specializes in plastic surgery disputes to directly represent the lawsuit. However, it should be noted that by proving that the other party failed in cosmetic surgery, you need to provide evidence to prove the following reasons: 1, there is a legal and effective contractual relationship between the original defendant; 2. The defendant violated the contract; 3. The defendant's breach of contract caused losses to the plaintiff; There is a causal relationship between the plaintiff's loss and the defendant's breach of contract.
