Oye, I'm guessing you posted this some time ago... If you can't get back to the store to make sure you either bought the right type of cream, or to buy the right type of cream (we're not even 100% sure this is the wrong one) try it - don't full out rub it in on all of those places that can be hard to clean easily, but just a little, on the outermost spot and see if it helps. Should it not help, or at this point you're not even willing to try (which I wouldn't blame you) get your butt back to a pharmacy quick, yes? And in the meantime, use cold water.
