Does seoborric dermatitis cause acne? seem to be getting a good few since i got this. also, does sd ever go into submission for long periods of time?

Not directly: Seborrhea does not usually directly cause acne, but the treatments use can clog the pores and create pimples. Seb derm is a chronic skin condition which is controllable, but not curable. Many people experience long periods of time with no or minimal symptoms, with occasional relapse when exposed to triggers (stress, chemicals, age, medications, illness, etc.).
