Help with acne treatments i received from dermatologist?

when he says it gets worse b4 it gets better its called "purging" ur face will look worse bcuz ur face is getting rid of all the bacteria inside ur skin-it rises to the top. then the treatment starts to cureit. bcuz u get rid of that bacteria, u will breakout much less. they tell u this bcuz so many times, peoples faces get worse and they freak out and think its making theyre face worse and stop using it. u have to keep using it! it sux that ur face gets worse but then its worth it.
