There are a lot of aspects about Michael's appearance and other issues that can be explained if you just look around and research a bit, and none of it is the sensationalist tabloid rumor crap. He never bleached his skin, he had vitiligo universalis and lupus. Vitiligo causes the skin pigmentation to become obliterated, and lupus medications can further that effect.

He had his first nose surgery done after he broke his nose after falling during a dance routine. He had his second surgery when scar tissue from the first was causing alterations in his voice. The surgeries were not done very well and he also became paranoid about his appearance (some believe he had a psychological disorder called body dysmorphic syndrome) and kept trying to "fix" it. He was somewhat anorexic because he was afraid of losing his 'dancing body' form. He was very mistreated and emotionally and physically abused by his father.

But there was a lot he did too. He was in the Guiness book of records for most charities given to by a pop star. When he was burned badly during a Pepsi commercial simulated concert. "PepsiCo settled a lawsuit out of court, and Jackson gave his $1.5 million settlement to the Brotman Medical Center in Culver City, California, where he had been treated, allowing the hospital to acquire the best available technology for treating severe burns; Brotman subsequently renamed its burn ward "Michael Jackson Burn Center" in his honor." (quoted from Taraborrelli, pp. 279–287, MJ biography).

Also stated in the biography:
Jackson stated that he was physically and emotionally abused by his father from a young age, enduring incessant rehearsals, whippings and name-calling. However, he also credited his father's strict discipline as playing a large part in his success. In one altercation — later recalled by Marlon Jackson — Joseph held Michael upside down by one leg and "pummeled him over and over again with his hand, hitting him on his back and buttocks". Joseph would also trip or push his male children into walls. One night while Jackson was asleep, Joseph climbed into his room through the bedroom window. Wearing a fright mask, he entered the room screaming and shouting. Joseph said he wanted to teach his children not to leave the window open when they went to sleep. For years afterwards, Jackson said he suffered nightmares about being kidnapped from his bedroom. In 2003, Joseph admitted to the BBC that he had whipped Jackson as a child.
I think it can be said he had a very hard life and was both glorified and then made a mockery of by the media.
