Yes, the acne completely stop.
Yes as well. My face is oily.

i think what the doctor given is acutane, a type of "tretinoin", which is proven very effective on acne and oily skin.

however this oral tretinoin is being monitor strictly, so doctor will consider first b4 give to patients, especially women. (pregnant women cannot take this medicine)

another alternative is apply tretinoin cream, it is a bit less effective but also less harm and less side effect.

you can go to any pharmacy to buy low dosage tretinoin cream, around rm 40 - rm60
