All cosmetic surgery is risky. Even the simplest double eyelids, rhinoplasty, are likely to have accidents. All cosmetic surgery will have side effects. The so-called "side effect" refers to the secondary effect produced at the same time as the primary effect, such as following lead. For example, as long as the skin is cut, it will leave scars, and the tip of the nose will harden as long as it is raised.
If you want what God didn't give you, you must pay the price. And this price is not just money. It needs the pain, scars and all kinds of possible long-term complications caused by your operation.
