As the lead singer of the Jackson Five Jacko was a normal-looking kid, everyone said he was cute and loads of girls fancied him.
BUT apparently his dad used to call him 'big nose' and so Jackson became very sensitive about his looks.
Michael also says that as he became a teenager his face changed and people didn't think he was cute anymore - that made him even more worried about his looks.
To make things worse he said he suffered from vitiligo, a condition that makes your skin go blotchy and change colour.
Probably in about 1984 Michael started having his face changed by plastic surgery.
