Plastic surgery is a surgical specialty that involves the restoration, reconstruction, or alteration of the human body. It is typically focused on improving a person's appearance, but can also include reconstructive procedures to correct physical deformities or injuries. Plastic surgeons use a variety of techniques such as skin grafts, tissue expansion, and fat transfer to achieve their desired results. Common procedures include breast augmentation, rhinoplasty (nose job), liposuction, and facelifts. Plastic surgery can have both physical and psychological benefits for patients, improving self-esteem, confidence, and quality of life.
