some people are even created that way, some people have darker toned legs than their faces, others have lighter toned arms than their legs, then as far as the joints most black people are 'naturally' heavily pigmented in those regions ( i guess it's a genetic thing

) I have a friend who is evenly toned all over her skin, even down to her buttocks!, so you really can not categorize one as bleaching because their knucles or knees are darker than the rest of the skin --- oh and By The Way
...Meddeen...You really don't want to know the number of black women who believe in the power of hydroquinone 2%, and it might be closer to home than you think... as long as it is done sensibly, in moderation and healthily...i dont know how someone can go morally wrong with that
