Also termed aesthetic surgery, it is the branch of plastic surgery involving undertaking procedures to change (hopefully, improve) physical features. It is an expanding branch of surgery and, largely outside the NHS, has been more lightly regulated in the UK. There is also a large market in non-surgical cosmetic procedures such as the use of dermal fillers, often by individuals who are not registered with a regulatory body. Concern over problems involving a particular type of breast implant found to have safety risks, the British government accepted the advice of a review committee in 2012, which proposed major changes in the governance and regulation of cosmetic surgery. This included tightening up the consent procedures, updating advertising restrictions and prohibiting financial inducements. The Royal Colleges of Surgeons are devising an accreditation system to allow patients to identify those practitioners recognised as competent and ethical and the GENERAL MEDICAL COUNCIL (GMC) has produced practice guidance.
