The concept of "genetic acne" is highly debated.

In terms of Accutane, I believe it treats acne regardless of the cause as it is reducing oil, shrinking pores etc.

I'm with genetic acne and used to take accutane treatment for 6 months. Just want to tell, accutane is not a permanent treatment for genetic acne. It will reappear on your face once the antibiotic of accutane is no more in your body.
Try to change your lifestyle, eat clean. You will slowly see the result on your face.
