Maybe for some people, but most of the people on here seem to get their oil back (at least from what I've seen).

It decreases the amount of sebum your body produces while on the drug. This occurs mostly on your face, back, and chest, the places where acne usually occurs. Once off the drug, the sebum levels are supposed to return to normal.

dosage dependant - beware..your body maystill produce some oil but it takes all the natural protective oils out of your skin across your entire body, I now have deep creases forming everywhere - shoulders, wrists, neck etc

my doctor said it makes some of her patients look much older than they are, i guess because of the lack of oil.
