What is the best concealer to use?

i really need help finding the perfect concealer for my skin. i dont like concealers that make ur face look whiter than the rest of your skin.i want something to blend it silky and have a natural tan.i use proactive so my face can get kind of dry, but i also need something that wont cause pimples by making it oily.right now im using SALLY HANSEN NATURAL BEAUTY INSPIRED BY CARMINDY,but it feels sort of thick and makes my face whiter than it really is.i need it to last all night, i dont want it to sweat off if im dancing like most makeup does. can someone please help or give some pointers ???
OH,and is it better to apply all concealers with the foam squares or is it ok to use your fingers…??
