When Michael Jackson passed away in 2009, his death left behind many unanswered questions about the eccentric pop star's alleged plastic surgery. Throughout his career, his dramatic transformation made him infamous as fans wondered exactly how much surgery he had and why his skin had become white.

In a 2003 documentary with Martin Bashir, Michael confessed to only having a nose job. "I’ve had no plastic surgery on my face, just my nose," he said. "It helped me breathe better so I can hit higher notes. I am telling you the honest truth, I didn’t do anything to my face."

As for his fair complexion, Michael told Oprah Winfrey back in the early '90s that he suffered from vitiligo, a skin condition that created pale blotches on his body. His dermatologist Dr. Arnold Klein confirmed that in 2009.

"His was bad because he began to get a totally speckled look over his body,” Klein said. “[It was] all over his body, but on his face significantly [and] on his hands, which were very difficult to treat.”
