Accutane for BlackHeads & WhiteHeads?

I was on accutane (trevissage) last year and it helps a lot to get rid of my comedones but after 8 months of finish the treatment the blackheads are coming back again. They are all over my nose, lip line, and forehead. so im thinkig in trying again accutane cause I was using retin a 0.5 every night about 3 months and I dont not see any results . I also squeeze every morning my nose and at the end of the day they reappear. so im frustrated. what else can i do?? I also quit alcohol, smoking.
