I seriously wouldn't attempt to do that. You would severely damage your skin, scarring would most likely occur, and the results would not be evenly distributed. There have been black entertainers who have tried it. Of course, Michael Jackson comes to mind, but he had an unnatural condition called vitiligo. I think Li'l Kim has bleached her skin some, and Beyonce Knowles has done something to her skin. I would imagine it cost them hundreds of thousands of dollars to get it done. If you're doing it because you feel it would give you social or employment advantages, use your mind instead of your body to accomplish it. Be the best you can be, also be well-groomed and intelligent, and that will carry you through.
