that stuff is designed to work after many uses, if there was an an instant permanent hair removal method, it would be big news! but unfortunatley we don't have such a thing.
there are some prescription strength creams that some have had decent results, but it's not permanent and you have to continue treating even after your beard is cleared (vaniqua is one that comes to mind).
i've been using a lotion that impedes hair growth for a couple years now and it has slowed growth, but not completely stopped hairs from growing. I had to stop using it on my face, becuase I am going through laser right now and I don't want to slow any hair growth so that it is actively growing during treatment. keep this in mind if you decide to get laser later on down the road (doesn't apply to electro)
wait a second, are we just talking about nair and the like? if so, I never had good results with that on my face and in many cases my face was worse off than if I just had a beard (chemical burns suck!).
