Discussions that mention benzaclin

Acne board

I have read a lot about retin-A micro on this board. What is this? Is it just a milder form of retin-A? Which one would work the best? Also, do both have an initial breakout? And would taking antibiotics(minocin) and using a topical such as benzaclin help control the initial breakout? Sorry for so many ?????. Thanks for any info!
