Please tell me what skin lightening cream is better for a dark skin person?

None of them: Just don't do it. In the US, where the world's trends are set, trying to change your natural color is considered the height of ignorance. Looking good is about physical fitness and self care, not skin shade. These chemicals can disfigure you -- Muchael Jackson had only a mild case and he looked awful. Embrace what nature gave you, get / stay fit and trim, and be proud of yourself.
