It may seem like the terms "cosmetic" and "plastic" surgery are used interchangeably, but, in fact, there are differences between these two medical professional specialties. Cosmetic surgery applies to those procedures, techniques and treatments used to change the appearance of the body that are non-surgical. Plastic surgery refers to surgical techniques and procedures used for both cosmetic and reconstructive purposes. Cosmetic and plastic surgeons have different requirements for medical training and accreditation. While plastic surgeons may provide some cosmetic procedures, cosmetic specialists cannot perform plastic surgery.
