Undecided Question

Is there a cream that can lighten skin a little bit?

I was watching The Tyra Show, and she had this special were darker colored women would use "bleach creams" to lighten there skin…
I want to know if there is any actual "bleach cream" that i can use to lighten beauty marks, and the dark circles around my eyes. Just looking for a name of the cream/lotion and if it was effective or not…
