What is an effective bleaching cream without hydroquinone? And why is hydroquinone so bad?

I'm trying to fade a way a scar and someone told me to use a bleaching cream without hydroquinone. Dr. Palmer's skin whitener has hydroquinone, and I thought it would be good. So now I'm sort of confused about what I should try.What is an effective bleaching cream without hydroquinone? And why is hydroquinone so bad?
It's bad because it's a carcinogen. Yet another carcinogen in US cosmetics...imagine that...





This use is banned in some countries (e.g. France) because of fears of a cancer risk.
