I was on Retin-a for a lonnnnng time, I really didn't like the product.. I'd assume you will see much more results with Epiduo, from what I researched people seemed to generally like adapalene better, and the combo of BP with it is all the better~ and you're right about the initial breakout.. since it's a weaker retinoid I don't believe you will experience any worsening of acne!

Good luck! (:
