Cosmetic surgery can enhance people's lives - but only if they truly understand what they are doing.
According to one plastic surgeon, too many people - as many as one in ten - are unhappy about the results of their cosmetic surgery.
However, this is not because the procedure has gone wrong or the surgeon has made a mistake, but simply because the patients have unrealistic expectations, says Dr Joe Gryskiewicz of the University of Minnesota.
The surgeon, who has been operating for over two decades, commented: "Cosmetic surgery is a wonderful option to improve the lives of many people; however often the patient's psychological reasons for having a procedure aren't considered or discussed prior to the surgery."
"With all of the new procedures and the attention given to the industry by the media, many patients develop unrealistic expectations about the impact that cosmetic surgery will have on their lives and if all elements aren't adequately considered, the patient won't be happy with the outcome," he warns.
Dr Gryskiewicz insists that patients should never have cosmetic surgery to please a partner or in reaction to a divorce or bereavement.
In addition, he advises that people should not go under the knife if they are suffering from depression in the belief that it will make them happy.
