i agree with jude, your best bet is to try something that's made to cover SERIOUS suff, like birthmarks, scars, etc...i don't know of any brands or anything, but i know that's what my mom uses when she wants her circles to disappear (we're sicilian, and we got them too!), and it works well.
cream-based products will ALWAYS provide more coverage too, just to keep in mind
