Anyone tried this bleaching cream?

Okey im confident now that i wanna get rid of my bluemarks (plus im interested in getting the anus a little bleached). I googled around and i see a lot of people talking about creams that contains hydroquinone. Did anyone try this?

This one for example: http://www.texasbeautysupplies.com/amskindisfad.html

I read reviews and most people seems happy but some says it has some negative sides too, and can irritate skin.
