I completed a 5 month course of Roaccutane (60mg a day) in August. Acne After Accutane?

I completed a 5 month course of Roaccutane (60mg a day) in August. The results were astonishing. Over the last 6-8 weeks my acne has slowly been returning. I've heard this isn't unusual, and it's still only at a moderate level, but like many acne sufferers the fear of substantial relapse is an ever-present one. Any advice on what approaches I should take in skin maintenance would be greatly appreciated. I don't mind the odd spot returning, but understandably don't want it coming back like before
