Like most acne meds, i assume this is no different that I'm getting my more than usual pimples is because of the differin i'm taking (2 weeks on it now)? The differin i assume is causing the initial break outs since i've been on benzamycin for about 4 months now and never got this many pimples before I assume its because of the addition of differin? Whats usually teh expected period of break outs usually last with the use of differin
