What other options are there besides Accutane? (finished 2 rounds)

I am a 24 year old male who finished a 2nd course of accutane 6 months ago but relapsed within 4 months and have been taking minocycline 100 mg 2x a day with 0.05% tretinoin every other night along with clindamycin wash in the morning for the past 2 months. The first course lasted several years and it didn't come back as bad by the time I started my second course though still was moderate and scarring. What would be the next step I could try before going on accutane for a third course assuming it doesn't get better? It's already been 2 months and I haven't seen much improvement
