Before having cosmetic surgery, or even consulting a surgeon, you should find out what qualifications he/she has. There are many different qualifications given by universities and professional associations in different countries. Like in many professional fields these days there are even bogus or sham “degrees” given by disreputable operators.
In some jurisdictions there is no restriction on unqualified people calling themselves a cosmetic surgeon.
In Australia, just about anyone with a standard medical degree is allowed to perform cosmetic surgery. In fact, currently there is no legislation to stop any doctor from calling themselves a ‘surgeon’, even without formal surgical training.
You should ensure that for any surgical cosmetic treatment your cosmetic surgeon is FRACS (Fellow of RASC) and is a member of ASPS. These professional memberships are only possible after 10 or more years of training and examination far beyond a mere medical degree.
You could be less discerning for non surgical superficial cosmetic treatment.
