The reduced sensitivity of Propionibacterium acnes to antibiotics is a growing problem. Resistance is a major issue not only because it can result in treatment failure but also because of concerns that it may potentially be transferred to other bacteria that anti-acne antibiotics are used used against. One of the most important factors predisposing to the development of resistant strains of propionibacterium acnes is the prolonged use of antibiotics. Therefore, in order to help minimize the development for such resistance, it is evident that maintenance strategies for acne should aim to minimize the long-term use of antibiotics.
