Hello im a college student and i have pimples that grow as large as m&m's. Since im worried about it I went to a dermatologist and prescribed me acnetrex (isotretinoin, capsule) for 8 months (its from the leaflet). So it really worked. But after the 10th month pimples started ruining and carving my face again. Here are my suspects from what I have read on some pages:
Stresstabs
Peanuts

What are the causes? And how to permanently seal my past of acnes. Im really worried again and well, im always teased.

Thanks in advance
