Plastic surgery refers to the scientific, technical and artistic medical science that uses medical techniques such as surgery, drugs and medical devices to repair and reshape the appearance and shape of various parts of the human body in order to enhance the external aesthetic feeling of the human body. Generally speaking, plastic surgery is human body carving. Simply put, plastic surgery is to correct the dissatisfied parts (face or body) through plastic surgery to achieve the desired appearance.
