Should I go back to Epiduo?

Hi Doc, I used Epiduo gel for 8mos. It cleared up my acne and it did wonders for my skin. I was able to tolerate the first weeks of initial irritation and it was magic for my skin. I then switched to Retacnyl 0.05 since 0.025 is not available in my country as a maintenance. I didn’t experience any irritation with it but I also noticed that I am becoming oilier and there are more congestion now that I’m in my second month using it. Should I switch back to Epiduo or stick wit Tretinoin. Thanks!
