Thankfully, society's understanding of plastic surgery has matured as the practice has demonstrated its ability to improve human well-being, as told to us by board-certified plastic surgeon Dr. John Zannis.

"Decades ago, I think it's fair to say there was a stigma that plastic surgery was for those with too much money and vanity, but now it's known to help people who have perfectly healthy reasons to alter their bodies -- from breast cancer survivors to people with breathing obstructions," Zannis said, who is head of the Zannis Center for Plastic Surgery.

"However, plastic surgery is a multi-billion dollar industry in the United States, and some of the doctors performing these procedures are not certified," the expert warned.

Recently, actress Renee Zellweger shocked much of the public with her new, post-surgical look.

"Zellweger has since stated that she embraces her new look, adding that change is the purpose of her surgery," Zannis said.

"However, many patients prefer to remain recognizable to their friends and family. Make sure to choose a procedure with a surgeon who grasps the idea of undergoing improvements while maintaining a recognizable appearance."
