Small White Bumps on Cheaks After Accutane Treatment?

I have just completed my 6 month accutane treatment. (40mg, twice a day) My acne is gone, HOWEVER it has been replaced by small white bumps on my cheaks (almost like little whiteheads...somewhat resembling keratosis pilaris) I have read up on this side effect and it seems to be very widely reported on accutane forums... Has any one heard of this? What is the cause of this? and, what can I do to get rid of it?? Thank-you in advance for your help!!
